[01:33:17] <just_pink> hi
[01:38:02] <ganzuul> http://i.imgur.com/8Bkg41A.gifv
[01:39:55] <just_pink> ganzuul: It work also with end mills?
[01:41:09] <ganzuul> I think the crankshaft is magical.
[01:41:20] <ganzuul> ~crank
[01:41:43] <ganzuul> How do I CNC masterwork/magical items?
[01:42:18] <toastydeath> carefully
[01:42:38] <just_pink> I broke 2 end mills today :(
[01:42:46] <ganzuul> awww
[01:42:55] <just_pink> with 8mm/min
[01:42:56] <ganzuul> Drink sorrows away?
[01:43:14] <ganzuul> I hear that slow speeds do that.
[01:43:21] <ganzuul> Fast speeds just wear out the tool.
[01:43:31] <just_pink> 1000 RPM
[01:43:47] <just_pink> it was 1/32" end mill
[01:43:47] <ganzuul> What material?
[01:43:55] <ganzuul> oic
[01:43:59] <just_pink> PCB
[01:44:03] <ganzuul> :o
[01:45:36] <just_pink> I think to order a turbine.. but really afraid from the noooois
[01:48:34] <MrSunshine> what type of endmill ?
[01:48:42] <MrSunshine> material
[01:49:29] <just_pink> cheap 1/32 with 1/8 shank
[01:49:36] <MrSunshine> hss ?
[01:49:44] <just_pink> yes
[01:49:49] <MrSunshine> well theres your problem =)
[01:49:59] <just_pink> I'm use it to cut the pcb
[01:50:01] <MrSunshine> pcb is a fibre glass material =)
[01:50:10] <MrSunshine> VERY abrasive
[01:50:33] <MrSunshine> a hss drill usaly lasts like ... 3 holes to drill the frekkin things
[01:51:03] <just_pink> I have hss drill that mak bore than 20 pcbs..
[01:51:15] <just_pink> more*
[01:52:29] <just_pink> each pcb has 30 holes * 20 pcbs = 600 holes!
[01:52:45] <just_pink> hss drill bit 0.8 mm
[01:52:51] <ganzuul> PCB material isn't all the same. They have various levels of quality and fiber content.
[01:53:37] <ganzuul> Cheap single-sided copper board for example look like they tried to mummify something.
[01:53:47] <just_pink> i got it from radio shack
[01:54:55] <just_pink> http://www.ebay.com/itm/10pcs-0-5-2-5mm-Micro-HSS-Straight-Shank-Twist-Drill-Bits-for-Drill-Tools-/251969947939?var=&hash=item3aaa944923
[01:55:03] <just_pink> drill bit
[01:56:10] <just_pink> http://1.bp.blogspot.com/-xjFjNqI9SmU/U3C8QtrKcrI/AAAAAAAABC8/yG_CGxPOy9o/s1600/276-1499-pcb.jpg
[01:56:13] <just_pink> pcb
[01:57:43] <just_pink> MrSunshine: ganzuul ^
[01:59:12] <MrSunshine> anyhow i would guess that endmill breakage is deteriation of the cutting edge =)
[01:59:17] <MrSunshine> put it under a microscope
[02:00:02] <just_pink> it just snap
[02:00:05] <MrSunshine> specialy if going to slow .. do not know the speeds to cut pcb with that kind of endmill but =)
[02:00:19] <MrSunshine> just_pink: directly ?
[02:00:54] <MrSunshine> 0.8mm endmill ... ok =)
[02:01:06] <MrSunshine> but that has to be carbide ?
[02:01:19] <MrSunshine> can they even make that small endmills in hss? =)
[02:01:24] <just_pink> 0.8 drill - for holes
[02:01:58] <ganzuul> just_pink: Yup. That's the cheap Chinese stuff.
[02:03:13] <just_pink> I also try to cut with the small center drill from HF - also snap
[02:05:34] <ganzuul> If you use this stuff on the backside of a one-sided PCB, you get a good ground plane, and you can shield stuff too: http://www.aliexpress.com/item/40MM-X-30M-Conductive-Copper-Foil-Tape-Free-Shipping/838170796.html
[02:06:00] <ganzuul> I ordered from them and was happy with the product and delivery.
[02:08:57] <just_pink> ganzuul: thanks but I have duble sided pcbs (30 of them) by mistake
[02:08:58] <Deejay> moin
[02:09:04] <just_pink> hi Deejay
[02:09:13] <Deejay> hi just_pink
[02:09:57] <just_pink> how is everything going with you?
[02:10:23] <ganzuul> just_pink: lol... better use them then xD
[02:13:34] <just_pink> 6 rings of yellow- solders, 6 ring of green solderd - now i need to make 6 rings of red
[02:13:49] <just_pink> but i dont have single side pcb!!
[02:22:28] <just_pink> Deejay: ganzuul - do you wat to see a pic of it?
[02:22:49] <ganzuul> sure
[02:27:20] <just_pink> http://i.imgur.com/IJoMN8P.jpg
[02:27:28] <just_pink> ganzuul: ^
[02:31:10] <ganzuul> Tricky.
[02:32:24] <just_pink> yes, It's tiny.. but fun to make
[02:40:47] <just_pink> JB-Weld can work on aluminum?
[02:58:50] <just_pink> time for pasta

[03:25:38] <just_pink> I've post it here before..
[03:28:12] <just_pink> ganzuul:do you think It's good idea to power the cnc in 4:05 AM?
[03:29:05] <ganzuul> Nope!
[03:29:21] <just_pink> why?

[05:53:17] <XXCoder> cool
[05:54:27] <XXCoder> I wish I am an engineer
[05:54:35] <XXCoder> I has a idea but unsure how to build it
[05:55:20] <just_pink> XXCoder: I wish I was an engineer also..
[05:56:35] <XXCoder> too bad eh heh
[05:57:16] <just_pink> I'm going to sleep

[05:57:36] <XXCoder> 3 am here
[05:57:45] <just_pink> good night.
[06:30:09] <stelicho> Hello all, I was hoping to get some help on possibly setting up a 5 axis mill with a galil DMC-2x00 motion controller. Has anyone had sucess setting up emc2 with galil boards?
[06:33:35] <Loetmichel> *meh* have to bike to the computer shop AGAIN... mHDMI to HDMI cable is to short to reach from tinkerPC to second TFT :(
[06:34:18] <jthornton> I'll have to sing in the rain while I bike this morning
[06:34:20] <XXCoder> I wish wormholes method has been discovered
[06:34:58] <XXCoder> it would be possible to use wormholes to thread with cable so you has cable with no limit
[06:36:07] <fenn> stelicho: i could be wrong but i think linuxcnc/emc2 is incompatible with galil DMC boards because the galil has an onboard computer that performs the same function as linuxcnc/emc2
[06:36:42] <fenn> stelicho: you can probably salvage the existing servo drives though
[06:37:48] <stelicho> fenn: I see. is there a way to set up linuxcnc/emc2 as the controller software?
[06:38:45] <malcom2073> Looks like it outputs +/-10v for servos, or stepper control to normal amplifiers/drivers, so you should be able to run it with linuxcnc using a mesaboard
[06:38:58] <malcom2073> run it meaning the maching, replacing the DMC-2x00
[06:42:33] <stelicho> malcom2073: which board would you reccomend to replace the galil board? are the daughter boards still usable?
[06:42:55] <malcom2073> stelicho: I'd recomend a PC with mesaboards inside :-D. And I don't know, are the daughter boards the servo drives?
[06:44:47] <fenn> stelicho: if you're set on keeping the galil, try mach3 as there is a plugin for galil cards that includes the 21x0 and 22x0 compatibility
[06:45:21] <fenn> otherwise you'd either have to scrap the galil card itself or be doing some serious hardware hacking
[06:45:44] <skunkworks> what are the daughter boards?
[06:46:22] <skunkworks> what issues are you having with the current setup?
[06:46:27] <stelicho> I think so. I havent gotten into the cabniet yet but looking at the book i'd say probably. DMC-2200
[06:47:13] <stelicho> Im not set on keeping the galil but maybe as a project what could I do to make it work? what hacks am I looking at?
[06:47:54] <stelicho> the galil is also quite old. you have to suply power to it constantly or else it wont turn back on without a heat gun
[06:48:18] <skunkworks> yikes
[06:48:50] <stelicho> the machine is down for maintainance (lead screw on x carrige broke from misalignment) so I have time to play around
[06:49:37] <fenn> the "hack" would involve writing a driver for the galil :)
[06:50:18] <fenn> skunkworks: you said there was ethernet capability added recently to linuxcnc, would that be a good template to copy for writing a galil driver?
[06:51:41] <skunkworks> fenn, I really doubt it. linuxcnc is still the motion controller.
[06:52:08] <skunkworks> the ethernet interface is at the hal level
[06:52:27] <skunkworks> just like any of the other external interface devices for linuxcnc
[06:52:42] <malcom2073> Heh reading the manual, it looks like the ethernet is just accepting gcode
[06:53:05] <fenn> a DNC DMC
[06:53:44] <stelicho> considering this is for a "maker/hackerspace" I am down to try my hand at that. Maybe I need to know more about linuxcnc
[06:57:33] <fenn> stelicho: the galil dmc boards are not really compatible with the linuxcnc "philosophy" of dumb peripherals, so this may just be an impossible task
[06:58:25] <fenn> it would be great if the trajectory planner inputs/outputs were exposed in hal so people could do this sort of thing
[07:02:07] <stelicho> so linuxcnc uses the system as the controller and goes to the peripherals where as the galil board is its own mico and just recives from the software. what about making a better version of the galil tools or is the firmware too closed source?
[07:03:10] <skunkworks> I don't think many around here know much about galil..
[07:05:18] <fenn> i'm not too clear on how you're *supposed* to use the board in the first place... there should be some software provided by galil to send g-code to the machine right?
[07:05:48] <fenn> http://galil.com/downloads/software
[07:08:06] <stelicho> Is there a way to configure emc to "send" rather than "control"? the mesaboards you mentioned would work with the controllers too right? the galil tools software will take commands but it is a painful process. We have mach3 with a galil profile but no pitch and yaw, also the galil does have to die at some point and they dont like it when we call them (because it's second hand)
[07:09:58] <mutley> morning all
[07:10:04] <stelicho> hi there
[07:10:29] <mutley> looking to replace electronics on an Isel CNC mchine ive got here
[07:10:59] <CaptHindsight> skunkworks: do you recall where the 3d model is for "Chips" as seen in your new trajectory planner video (that I can't find the link to at the moment)
[07:11:25] <mutley> the intenral electronics are screwed, y axis circuit burnt out, still runs but very quickly overheats and skips steps, pcb is clearly showing signs of this overheating
[07:11:52] <mutley> so im looking at 4amp bipolar stepper drivers, and a controller
[07:11:55] <skunkworks> CaptHindsight, what video?
[07:12:53] <mutley> i guess im open to using a pc box with linuxcnc, but wondering if anyone knows a decent supplier of good value stepper drivers, preferably uk based
[07:13:05] <CaptHindsight> skunkworks: a youtube for the new trajectory planner using that small training stage, was last year
[07:13:23] <mutley> otherwise a reccomendation for stepper drivers, and i dont have the budget fo gecko drives
[07:13:29] <mutley> :)
[07:14:09] <skunkworks> CaptHindsight, this one? https://www.youtube.com/watch?v=HPzow8L1dxw
[07:14:13] <malcom2073> mutley: Look at T6600's on ebay, they're about $12, and seem to do alright
[07:14:37] <mutley> hey malcom2073
[07:14:47] <malcom2073> Heya
[07:14:59] <mutley> malcom2073: ok they sound like god value
[07:15:02] <mutley> good*
[07:15:10] <malcom2073> Also check out leadshine DM542's. I've used them with great success
[07:15:16] <mutley> i got leadshine dm442 drivers on the bigger machine here,
[07:15:18] <malcom2073> They're a bit more expensive, but known to be good
[07:15:26] <CaptHindsight> skunkworks: yes as seen at ~ 1:00 https://youtu.be/HPzow8L1dxw?t=1m1s
[07:15:45] <mutley> the original electronics have a choice of single or half step, and thats it
[07:15:52] <mutley> its a machine from early 90s
[07:15:56] <mutley> late 80s
[07:16:20] <mutley> the machine is built like a tank, rock solid, and its in near perfect condition,
[07:16:45] <mutley> malcom2073: any suggestion on a controller?
[07:16:52] <malcom2073> mutley: LinuxCNC of course :-D
[07:17:05] <malcom2073> Get an old PC with a parallel port and go to town
[07:17:08] <mutley> yea i know, anything other options?
[07:17:22] <mutley> well i do have an old box with par port under the bench here
[07:17:48] <malcom2073> It a mill or what?
[07:17:55] <mutley> yea cnc mill
[07:19:10] <CaptHindsight> https://www.youtube.com/watch?v=Qp0ZpxsgxVs is "Chips" in the sample programs on the LiveCD?
[07:19:14] <fenn> CaptHindsight: that's an old model that used to be in an ftp directory on linuxcnc.org somewhere
[07:19:18] <jthornton> isn't leadshine what they use a lot in uk for stepper drives?
[07:19:32] <malcom2073> I'd use linuxcnc, but I've only really played aroudn with grbl, smootheboard and mach3. Haven't been happy with any of them
[07:19:59] <skunkworks> CaptHindsight, http://electronicsam.com/images/KandT/testing/LHchips4.ngc
[07:20:26] <mutley> yea leadshine seem to be quite well established
[07:20:35] <skunkworks> but that the feed is set to F999actualfeed. so you you wanted to run at what it was cam'ed to - you would have to remove the 999
[07:21:00] <mutley> malcom2073: yea i might just have to bite the bullet o something a bit beyond my original budget
[07:21:10] <CaptHindsight> skunkworks: thanks, I wanted to use it to make a Howto for making PP molds for custom made Gummys
[07:21:15] <malcom2073> mutley: Tbh, linuxcnc as a controller is near free
[07:21:22] <malcom2073> especially if you have an old PC laying around
[07:21:55] <malcom2073> Certainly worth the try, since drivers are reusable for any controller
[07:22:00] <malcom2073> drives*
[07:24:54] <fenn> CaptHindsight: "Probably not the same version, but should help for something.
[07:25:02] <fenn> CaptHindsight: http://dsplabs.upt.ro/~juve/emc/tux/
[07:25:21] <CaptHindsight> https://youtu.be/qrypdAGEZBg?t=1m58s mill PP patterns and then press into corn starch for the molds
[07:25:39] <fenn> it's a different model than the 3D_Chips.ngc example program
[07:25:57] <skunkworks> fenn, awesome! I could not remember where I got them
[07:26:23] <CaptHindsight> thanks, I didn't want to generate a new model
[07:26:54] <CaptHindsight> ah the .stl is there, I can scale it
[07:27:23] <mutley> malcom2073: yea this is true
[07:27:54] <CaptHindsight> milling 1" high patterns out of PP or HDPE should go pretty quick
[07:29:18] <CaptHindsight> and a corn syrup (Twizzlers) type formula vs gelatin could speed up the process to make custom Gummys
[07:30:21] <fenn> melted gummy worms would be gummier
[07:32:42] <fenn> not sure why people need custom gummy candy
[07:32:46] <skunkworks> http://www.machsupport.com/forum/index.php/topic,30580.msg212622.html#msg212622
[07:32:55] <CaptHindsight> low pressure injection molding using a Twizzlers formula would also be quick
[07:33:11] <CaptHindsight> fenn: need vs want
[07:33:25] <fenn> would an aluminum heatsink type mold go faster?
[07:33:42] <CaptHindsight> but it also needs to meet NSF
[07:34:01] <fenn> i don't know what that implies
[07:34:06] <CaptHindsight> not sure if aluminum molds would meet the spec
[07:34:56] <CaptHindsight> http://www.nsf.org/services/by-industry/food-safety-quality/
[07:37:10] <fenn> it's in their interest to keep you guessing
[07:37:42] <fenn> "Our wide range of auditing, consulting and certification services"
[07:40:07] <CaptHindsight> Aluminum is not a problem, though SS is usually preferred but not necessary
[07:40:39] <CaptHindsight> http://standards.nsf.org/apps/group_public/download.php/3941/nsf51-97.pdf
[07:42:26] <CaptHindsight> so aluminum low pressure molds or patterns are not a problem
[07:44:59] <fenn> what i'm getting from this document is that it's OK to have lead in your food-contacting materials as long as you intended it to be there
[07:46:10] <fenn> as long as it's limited to tea, coffee, or water, and doesn't exceed 8%
[07:46:43] <CaptHindsight> blame it on CFR21
[07:49:10] <CaptHindsight> 7.3.2 Brass and bronze may be used in a food zone where exposure to food is clearly and specifically limited to tea, coffee, or water. When used, the lead content of brass and bronze components shall not exceed 8.0 percent.
[07:51:55] <CaptHindsight> so 6061 and 6013 are acceptable
[07:53:06] <fenn> yay
[07:55:16] <fenn> skunkworks: joeaverage is incorrect, the RTAI kernel is a true realtime OS and runs on PC. but he is right that some "realtime" linux kernels are not true realtime just low latency
[07:55:53] <fenn> also i can take a dump in a box and guarantee it's a piece of shit
[07:57:18] <fenn> simply accepting a "guarantee" without testing is what caused the recent spacex launch failure
[08:03:07] <CaptHindsight> it's faster milling polypropylene, cutting speed (ft/min) 920-1640
[08:03:50] * jthornton doesn't even have to look at radar to know riding in the woods is not on the agenda today
[08:14:52] <CaptHindsight> cornstarch molds work for chocolate as well
[08:17:28] <CaptHindsight> 3D scanner to candy in <1 hour
[08:37:38] <_methods> heheh dump in a box
[08:37:44] <_methods> schrodingers turd
[08:39:07] <CaptHindsight> live or dead turd?
[08:41:10] <_methods> hahah
[08:41:17] <_methods> you'd have to ask fenn i guess
[08:41:24] <_methods> his experiment
[08:41:43] <_methods> might also make a good saturday night live song
[08:41:49] <_methods> dump in a box
[08:42:09] <CaptHindsight> not much of a market for custom molded versions either, so must be another topic
[08:44:33] <CaptHindsight> what's the lowest cost 3d-ish scanner for people faces?
[08:44:48] <fenn> camera and software
[08:44:53] <CaptHindsight> probably an app using your phone
[08:45:03] <fenn> phones are terrible and should be banned
[08:45:37] <fenn> autodesk makes an app but it's terrible
[08:46:24] <CaptHindsight> http://3dprint.com/15947/autodesk-123d-catch-android/ yeah just good enough
[08:48:12] <skunkworks> fenn, have you played with autodesk 360?
[08:48:44] <CaptHindsight> just needs to generate a reasonable facsimile of a persons face on a ~1" dia pattern
[09:01:55] <fenn> david-3d with a decent camera and a standard video projector can do impressive stills at high resolution.. i can't find the original thread but here are some examples: http://fennetic.net/irc/structured_light_scan_david3d_johanna.jpg http://fennetic.net/irc/structured_light_scan_david3d_shoe.jpg more examples here: http://forum.david-3d.com/viewforum.php?f=15
[09:02:21] <fenn> as usual with data acquisition systems there is a time/space resolution and SNR tradeoff
[09:02:43] <fenn> you can have a quick but crappy scan or a slow but high quality scan
[09:05:46] <fenn> there are various open source structured light scanning apps but the whole field seems terribly disorganized and i haven't completed my research into what's available and what actually works
[09:06:08] <fenn> s/apps/programs and pieces of source code that may or may not do anything/
[09:08:46] <CaptHindsight> http://www.ebay.com/itm/3-Axis-CNC-Router-Engraver-3020T-Engraving-Drilling-Milling-Machine-USA-/301114608328
[09:09:58] <CaptHindsight> I really don't know how they can offer a 1 year warranty on this ^^^
[09:10:18] <fenn> this might be more relevant to your use case http://forum.david-3d.com/viewtopic.php?f=7&t=5542&hilit=contest&start=30
[09:11:30] <CaptHindsight> the David scanner
[09:12:51] <fenn> it's confusing because they sell a laser scanner (hardware) but their software supports structured light scanning with off the shelf cameras and projectors
[09:13:24] <CaptHindsight> most have a smartphone, scan to candy in under an hour, the carrageenan formula sets up in <15 minutes
[09:14:24] <fenn> so people would be ordering candy from you over the internet?
[09:14:52] <fenn> or they would get the molds? or you set up shop at a touristy spot or what?
[09:15:21] <CaptHindsight> school fund raisers, touristy places etc
[09:16:06] <fenn> i considered doing the 3d portrait thing at fisherman's wharf, i think people would pay for that
[09:16:26] <fenn> but i'm not sure about candy, people expect candy to be cheap
[09:17:25] <CaptHindsight> candy, chocolates, ice cream, cookies, cake etc
[09:18:54] <CaptHindsight> Edible Arrangements
[09:19:36] <fenn> bite the head off your very own board member
[09:20:15] <malcom2073> Heh, 1 year warranty: My guess? They don't pay for shipping, and require you to ship the whole machine back. Banking on the fact that nobody will do that
[09:20:56] <CaptHindsight> yeah, how can the "spindle" last that long if used?
[09:23:09] <CaptHindsight> I recall seeing some smaller ones on ebay
[09:25:48] <ssi> morn
[09:27:13] <CaptHindsight> 3" x 5" would be plenty
[09:27:40] <fenn> the table size is roughly a sheet of paper, would smaller even be any cheaper?
[09:31:53] <CaptHindsight> not by much unless you make enough and maybe start knocking parts out of sheet metal
[09:32:30] <fenn> i am thinking a kit made from sheet metal and the user pours concrete into it after assembly
[09:53:08] <Deejay> re
[10:15:16] <SEL> hello
[10:18:50] <skunkworks> hello
[10:19:21] <zeeshan|2> hi
[10:22:03] <PetefromTn_> yo
[10:22:08] <ssi> HI
[10:22:39] <PetefromTn_> buenos dias?
[10:22:45] <SEL> hi
[10:27:02] <zeeshan|2> how do you check if the table is perpendicular to the column?
[10:27:13] <zeeshan|2> you put a cylindrical square on the table
[10:27:31] <ssi> jog the head up and down and run an indicator against your cylsquare
[10:27:32] <zeeshan|2> and mount the dial indicator on the spindle quill for example
[10:27:34] <zeeshan|2> and jog up and down?
[10:27:40] <ssi> or use something like a protram
[10:27:57] <ssi> or an indicator holder and spin it around and measure the table 180 degrees out
[10:28:04] <ssi> all the same stuff as tramming teh head on a bridgeport
[10:28:14] <zeeshan|2> youd do this in the ZY plane right?
[10:28:21] <zeeshan|2> and ZX plane
[10:28:28] <ssi> yes
[10:28:30] <zeeshan|2> well zy plane would show its messed
[10:28:47] <PetefromTn_> actually that is not right
[10:28:55] <PetefromTn_> there are two things in play here
[10:29:05] <PetefromTn_> the perpendicularity of the column to the table
[10:29:16] <PetefromTn_> and the perpendicularity of the spindle to the tbale
[10:29:17] <PetefromTn_> table
[10:29:22] <zeeshan|2> yes
[10:29:24] <zeeshan|2> my next test was
[10:29:36] <zeeshan|2> i mounted indicator on table
[10:29:41] <zeeshan|2> and moved the quill up and down only
[10:29:49] <zeeshan|2> to check if the spindle was perepndicular to the table
[10:29:52] <PetefromTn_> if you just use a pro tram or sweep the table it will only tell you the spindle is square at that particular height
[10:30:03] <ssi> true
[10:30:08] <ssi> sweeping a cylsquare will do it though
[10:30:54] <PetefromTn_> I would put the indicator on the column and sweep the edge of the cylindrical square up and down raising the table and lowering the table in both X and Y
[10:31:39] <PetefromTn_> then once you have the column adjusted to the table you can worry about the spindle tram with as stated before you can use a protram or sweep the table...I use a bigass bearing race laid on a clean table top
[10:33:01] <SEL> i made a lcnc configuration with 4 axis, the 4th axis (A) is rotative. i have set home_search_vel to 0 for the A axis, this alone won't home the A axis at current position, this needs also home_sequence = -1 :-)
[10:33:31] <archivist> zeeshan|2, http://www.ebay.co.uk/itm/Milling-Head-Square-Tramming-Gauge-Edge-Technology-1-8-Shank-/231205535219
[10:34:07] <archivist> that gets spindle to table right
[10:34:11] <PetefromTn_> why would you have home search velocity at zero?
[10:34:32] <SEL> to home the A axis at current position without moving
[10:34:58] <archivist> to tell the A to use its current pos as home to save a seek to no switch
[10:35:13] <SEL> exact
[10:35:24] <archivist> I use a level :)
[10:37:30] <zeeshan|2> 11:07:57] <PetefromTn_> I would put the indicator on the column and sweep the edge of the cylindrical square up and down raising the table and lowering the table in both X and Y
[10:38:00] <zeeshan|2> you must have a big mag base :{
[10:38:21] <zeeshan|2> i am on a forum where people have similar type machine trying to get some help
[10:38:27] <PetefromTn_> meh any mag base should work?
[10:38:28] <zeeshan|2> it really sucks i dont have a manualk for this
[10:38:40] <zeeshan|2> this is my dilemma:
[10:38:44] <zeeshan|2> for #1 -- table to column check, I put a cylindrical square on the table and mounted the mag base on the quill. The dial indicator was touching the Cylindrical square for first the ZY plane and then second the ZX plane. I jogged the machine up and down and saw no indicator movement.
[10:38:52] <PetefromTn_> SEL I suppose there is no home switch on the A is what you are saying
[10:38:54] <zeeshan|2> for #3 -- I mounted mag base to the table with the indicator touching the quill in the first the ZY plane and then the ZX plane. I moved the quill up and down manually. I zero'ed the indicator at the largest possible extension of the quill and closed it to get my readings. I noticed that the ZY plane displayed an error of +0.0015
[10:39:01] <zeeshan|2> logically I was thinking this is telling me that the table isn't perpendicular to the column.
[10:39:27] <SEL> the A axis is rotative and without limit switches
[10:39:59] <PetefromTn_> SEL OK sorry I misunderstood
[10:40:14] <zeeshan|2> never be sorry!!!!!!!!!
[10:40:29] <zeeshan|2> that is a weird config!!!!!!!
[10:40:31] <zeeshan|2> :P
[10:41:47] <archivist> zeeshan|2, there is also a mirror technique with a collimator horizontal and an optical square, then a mirror on the Z
[10:42:10] <zeeshan|2> archivist: double slit experiment?
[10:42:11] <zeeshan|2> :-)
[10:42:16] <archivist> no
[10:42:19] <zeeshan|2> im kidding
[10:42:23] <SEL> so I've set home_search_vel to 0 and effectively the motor is not moving but not homing too. It started working when I have also set home_sequence = -1 for the A axis
[10:42:29] <zeeshan|2> archivist: im not setting up a cmm here :P
[10:42:34] <zeeshan|2> just a mill to within a thou :P
[10:42:35] <archivist> proper old school machine testing
[10:43:10] * archivist waves his testing machine tools books at all teh zeeshans
[10:43:21] <zeeshan|2> heheh
[10:43:36] <zeeshan|2> archivist: if youre so intro metrology
[10:43:46] <zeeshan|2> are you into how t hey measure things like speed of light
[10:44:45] <zeeshan|2> the cern accelerator must fancy you
[10:45:01] <zeeshan|2> it is currently the most precise measuring equip in the world!
[10:47:39] <archivist> I have a visitor
[10:49:29] <trentster> Ok all - just put the new beta version of the CNC Community site live - check it out http://cnc4.me/ all feedback welcome ;-) I would like to make it as beneficial as possible to folks
[10:51:38] <PetefromTn_> they are gonna blow up the world from cern ;)
[10:51:53] <zeeshan|2> hah
[10:52:14] <PetefromTn_> Just kidding man
[10:53:32] <PetefromTn_> they are doing some things that have never been done before to be sure... I just get a bit annoyed at some of the really out there ideas they talk about. Who knows what they will actually find with that collider.
[10:54:18] <zeeshan|2> i have issues with that too
[10:54:26] <zeeshan|2> a lot of this quantum mechanics stuff
[10:54:28] <zeeshan|2> has solid
[10:54:37] <zeeshan|2> and i really mean solid experimental backing
[10:54:54] <zeeshan|2> im trying to learn it -- and its been an annoying endeavour
[10:55:06] <zeeshan|2> cause a lot of courses just talk about random math etc
[10:55:19] <zeeshan|2> i dont give a shit about some random math that is trying to explain phenomenon
[10:55:37] <zeeshan|2> i want to know the experiment someone did, the results, and why they picked a math model that explains it
[10:55:41] <zeeshan|2> that's the proper way to learn something
[10:56:11] <zeeshan|2> anyone can go and say Pete = k*e*m*c^2/ Force
[10:56:12] <zeeshan|2> :)
[10:56:24] <zeeshan|2> that might not be dimensionally correct, but you get the point :P
[10:57:00] <PetefromTn_> it should read....
[10:57:12] <PetefromTn_> PETE= FREAKING AWESOME IN EVERY WAY!!
[10:57:21] <PetefromTn_> ;)
[10:57:23] <zeeshan|2> :D
[11:03:58] <ganzuul> trentster: Github Oauth
[11:05:23] <trentster> ganzuul: ?
[11:05:25] <ganzuul> PetefromTn_: CERN's energy levels are much lower than what's going on out in deep space.
[11:05:46] <ganzuul> trentster: To make registration easier. Same as Twitter.
[11:07:26] <ganzuul> zeeshan|2: Regarding QM, the only interpretation which has been disproven is the Copenhagen one.
[11:07:49] <PetefromTn_> the sky is falling!!
[11:08:13] <trentster> ganzuul: aah yeah Oauth would be nice to have but its not a current integration mechanism. The only other one there is facebook, which I have not enabled yet, perhaps I should, what do you think?
[11:08:25] <ganzuul> Well poop! Guess they done gone done it after all.
[11:09:34] <ganzuul> trentster: Linked in too. Might be worth the effort of seeing how those plugins are made, and fiddle with their fiddly bits.
[11:10:46] <ganzuul> zeeshan|2: Lasers are a really good way to understand more about quantum mechanics BTW.
[11:11:04] <archivist> .me giggles at <body></body></html> a blank page
[11:11:34] <PetefromTn_> I think it's /me
[11:11:46] <trentster> archivist: sorry :-(
[11:11:48] <archivist> next door key
[11:11:50] <ssi> lasers are good for a lot of things
[11:12:00] <PetefromTn_> LOL
[11:12:05] <jdh> like home remodeling?
[11:12:19] <ssi> exactly
[11:13:19] <ssi> https://pbs.twimg.com/media/CLqATA1WEAAD5ft.jpg:large
[11:13:22] <ssi> it's coming along btw
[11:13:54] <PetefromTn_> gotta hurry up so you can get your new Laser cutter back in there huh :D
[11:14:07] <ssi> exactly
[11:14:27] <archivist> the page source http://www.collection.archivist.info/archive/grabs/Screenshot-28.png
[11:14:30] <PetefromTn_> I thought you were going to sell it and move to the airport or something?
[11:14:40] <ssi> I am
[11:14:45] <ssi> but I have to finish it first
[11:16:34] <trentster> archivist: sorry mate its built with https://www.meteor.com/ which is a javascript app platform - you won't have much luck with non modern browsers.
[11:16:42] <ssi> also this
[11:16:42] <ssi> https://pbs.twimg.com/media/CLqA7SWWoAAtHGc.jpg:large
[11:16:44] <ssi> was my weekend
[11:16:46] <ssi> ftw
[11:16:46] <malcom2073> archivist: is... well... an archivist.
[11:16:53] <malcom2073> He does things much as you'd assume with his name :P
[11:17:17] <MacGyverX> How difficult is it to add a couple of buttons to AXIS?
[11:17:34] <ssi> MacGyverX: gladevcp makes it pretty simple
[11:17:38] <MacGyverX> Is there a xml/ini file that has the GUI parameters?
[11:17:50] <ssi> yep
[11:17:59] <archivist> can be easy, there is even a step in stepconf to add some
[11:18:02] <ssi> not for the regular axis ui, but for the addon panel
[11:18:16] <MacGyverX> stepconf is the devil. heh.
[11:19:01] <archivist> apart from the orrible stepconf it is just an editing exercise
[11:19:05] <MacGyverX> I use Rockhopper to change any config values
[11:20:01] <archivist> trentster, you need to get used to people complaining too JS is not the one and only way
[11:21:24] <archivist> JS does work on my browser
[11:21:45] <mozmck> MacGyverX: You have a link for Rockhopper? What is bad about stepconf?
[11:22:25] <archivist> it does not re read actual editied hal and ini files
[11:22:40] <mozmck> Oh, yes - I don't like that.
[11:23:18] <archivist> so trashes anything you add unless you put it in some special file that can be included
[11:23:34] <furrywolf> trentster: took forever to load, requires javascript, ugly. sorry....
[11:23:38] <mozmck> I have some ideas for a configuration program that would do that properly.
[11:23:44] <trentster> archivist: yeah - I know - i am sorry mate. If it helps I dont mind posting your stuff on there on your behalf, I know you have a lot of great knowledge to share.
[11:24:03] <malcom2073> trentster: You're not liable to find many people into web 2.0 here
[11:24:15] <furrywolf> also, is it just a list of videos? that seems pretty useless...
[11:24:22] <ssi> web 2.0 is so 2005
[11:24:24] <ssi> haha
[11:24:50] <malcom2073> Yep, and some people still haven't even gotten that far :P
[11:24:51] <trentster> furrywolf: its hosted far away from you as well so quite a lot of latency involved, once/if it builds up momentum I will colocate it to a LA datacenter we use.
[11:25:04] <archivist> I think a blank screen is web .0000002
[11:25:07] <furrywolf> I'm trying to figure out what the buttons even do. there's unlabeled up and down arrows. clicking them goes to a login page. huh?
[11:25:28] <trentster> furrywolf: I just seeded it with some content I liked, Hoping that others would do the same.
[11:25:32] <furrywolf> doesn't even tell me what I'm logging in TO...
[11:25:37] <malcom2073> That being said, trentster, you should probably check for JS capatability, and notify the user that their web browser is not comptible
[11:25:44] <furrywolf> or what the buttons would do if I did log in.
[11:26:01] <trentster> malcom2073: yeah when itys out of beta for sure great idea
[11:26:21] <furrywolf> and none of the links actually point to where they go, instead they go through some stupid redirect?
[11:26:22] <archivist> malcom2073, obvious that the cms involved writers dont care a bit
[11:26:37] <archivist> get a working cms
[11:27:39] <furrywolf> you have options for top, new, and best, with no definition of what they mean. how's top and best different? what metrics are these based on, since there's not even a date shown?
[11:27:41] <mozmck> It's probably written by kids who think *everybody* is on twitter and mobile phones now.
[11:27:46] <trentster> furrywolf they work for me they should take you to the link of the video or webpage etc.
[11:28:04] <trentster> archivist: it looks like this btw http://monosnap.com/image/13tZdYRIeek6VAtH3B36554OQ1mDfS.png
[11:28:06] <furrywolf> and what the hell does " 1 point an hour ago " mean anyway?
[11:28:06] <mozmck> Is that site supposed to be competition for cnczone or something?
[11:28:41] <trentster> it means one person clicked the up arrow to say they liked it - namely me
[11:28:44] <furrywolf> "Login forbidden" that's a nice one.
[11:29:02] <furrywolf> ok, so the up arrows have something to with liking things. would be nice if they were LABELED...
[11:29:15] <trentster> once more people start adding stuff and liking it/ranking it the popular stuff starts to float to the top of the list
[11:30:02] <archivist> I have never hit a like button yet anywhere
[11:30:09] <furrywolf> gah, and it can't even go to your profile page without waiting for a bunch of javascript crap to load.
[11:30:21] <trentster> its not really a like button its like a vote
[11:31:29] <ganzuul> https://www.reddit.com/r/Machinists/comments/3dg0id/just_a_few_notable_sayings_that_ive_heard_over/
[11:31:35] * ganzuul snarfles
[11:31:36] <trentster> furrywolf: its still in beta and I did not create the framework or the app have a look at http://www.telescopeapp.org/
[11:31:37] <archivist> does anybody remember google +1 button that one could add to sites, google itself told me it slowed my pages down
[11:32:06] <trentster> maybe you could suggest and help build something better? :-) would be great a you seem to be quite a technical chap
[11:33:17] <furrywolf> I haven't yet figured out why it even exists. :P
[11:33:34] <trentster> yup
[11:33:52] <malcom2073> I kinda wish the cnc group could get into the 21st century when it comes to web forums and the like... but for every person like me who wants that, there are at least 10 who still run their browsers without javascript :P
[11:34:43] <furrywolf> malcom2073: I have functioning javascript. that doesn't make it any faster to load or any less stupid.
[11:34:52] <archivist> I see the number of server requests slowing the web down a lot, it is a poor design for speed idea
[11:35:14] <ganzuul> trentster: Are you using nginx?
[11:37:18] <furrywolf> malcom2073: cnc people often tend to be practical people, and just want to see the content quickly and simply, without a bunch of useless crap. :P
[11:38:20] <malcom2073> furrywolf: Heh/
[11:38:39] <furrywolf> rounded boxes are for art majors. :P
[11:40:21] <archivist> rounded boxes can be done in css and html, no js needed
[11:40:56] <furrywolf> yes, I know. I am, in fact, reasonably proficient at CSS. I was just using it as an example of something strongly associated with web 2.0 design. :P
[11:41:06] <archivist> the use of js seems to be a badly implemented fad
[11:41:08] <furrywolf> I used CSS3 transforms the other day. :P
[11:42:03] <ganzuul> There are many ways to write bad and slow JS...
[11:42:13] <trentster> ganzuul: no it uses node.js
[11:42:13] <furrywolf> I'm not even sure why JS is so popular... it's harder to write than doing the exact same things server-side.
[11:42:30] <trentster> can put nginx proxy in front of it tho
[11:42:50] <malcom2073> furrywolf: Easier to distribute the code to peoples PC's, than to load the server down wit hprocessing
[11:43:04] <ganzuul> trentster: That'll speed it up a lot.
[11:43:15] <furrywolf> malcom2073: cpu is cheap, and unless it's crap code, doesn't use much of it. :P
[11:43:18] <malcom2073> That, and you can't do the exact same thing server side in most cases.
[11:43:42] <archivist> actually loading peoples PCs with crap is exceedingly rude
[11:43:43] <furrywolf> you can't generate a list of videos server-side? :P
[11:43:54] <malcom2073> furrywolf: You can't dynamically update that list without refreshing the page, no
[11:44:22] <furrywolf> malcom2073: and refreshing the page when you want to see if there's new videos is a bad thing? :P
[11:44:43] <malcom2073> furrywolf: Yep
[11:44:45] <malcom2073> Bad design practice.
[11:44:53] <furrywolf> lol
[11:45:06] <furrywolf> I don't wany any of my bandwidth being used unless I initiate it.
[11:45:08] <furrywolf> ever.
[11:45:30] <malcom2073> Change is scary eh?
[11:45:41] <ganzuul> ...I don't think there is one good design practice. - What makes wikipedia work is that all the articles follow the same format.
[11:45:48] <furrywolf> Spending my change because of your bad web design, yes.
[11:45:49] <archivist> these people do not understand the costs piled onto the uses
[11:45:53] <trentster> wow furrywolf is one tough customer :-)
[11:45:58] <zeeshan|2> http://www.busybeetools.com/products/v-block-4.html
[11:46:00] <zeeshan|2> am i missing something here
[11:46:03] <ganzuul> So you just need to be internally consistent as a minimum.
[11:46:05] <zeeshan|2> what is the capacity of this v-bock
[11:46:07] <zeeshan|2> v-block
[11:46:22] <archivist> trentster, nope, we are the people paying for bandwidth
[11:46:26] <zeeshan|2> it looks like theyre giving you overall dimensions
[11:46:28] <zeeshan|2> makes no sense? :P
[11:46:35] <malcom2073> archivist: A website pays much more for bandwidth, than you do
[11:46:35] <furrywolf> malcom2073: especially with the rise of mobile devices, people are PAYING for all the bandwidth you waste.
[11:46:45] <archivist> malcom2073, not true
[11:46:53] <furrywolf> LOL
[11:46:59] <trentster> so archivist that $14 break out board arrived today - gonna slap it in tomorrow and hope for the best. I probably should cut the 2nd gantry side before I start tinkering tho.
[11:47:00] <furrywolf> I pay $11/GB.
[11:47:08] <zeeshan|2> ssi nice pic dude
[11:47:09] <furrywolf> my linode is $20 a month and includes hundreds of GB.
[11:47:13] <ssi> zeeshan|2: :D
[11:47:13] <zeeshan|2> the water looks fantastic down there :P
[11:47:19] <ssi> it's so nice... trip was amazing
[11:47:36] <malcom2073> Anyway, this conversation is rapidly going nowhere :P
[11:47:49] <ganzuul> I pay 20e/mo for 100/50Mbps...
[11:47:55] <zeeshan|2> ganzuul: what is the copenhagen one?
[11:48:03] <furrywolf> malcom2073: care to explain how a few cents per gb is more than $11/gb? :P
[11:48:10] <zeeshan|2> ssi where is that pic taken @
[11:48:12] <zeeshan|2> approx
[11:48:13] <malcom2073> furrywolf: Not to someone who really doesn't care... nope
[11:48:20] <archivist> zeeshan|2, you could scale the image and measure
[11:48:42] <zeeshan|2> archivist: no
[11:48:49] <zeeshan|2> that is assuming its not a generic pic

[11:49:07] <ssi> zeeshan|2: uhm we were enroute home and we had just passed new providence island / nassau
[11:49:15] <zeeshan|2> ganzuul: i dont like theories just based on math
[11:49:18] <zeeshan|2> i want experimental evidence
[11:49:23] <zeeshan|2> that sounds like it had no experimental evidence
[11:49:42] <ssi> if I had to guess I'd say roughly here

[11:49:47] <furrywolf> I think methods is one of those people who has an inexpensive, high-speed, low-latency link, and has forgotten that 90% of the planet does not.
[11:50:01] <zeeshan|2> wow cool
[11:50:09] <zeeshan|2> looks so nice
[11:50:33] <zeeshan|2> wait whats going on what that google map
[11:50:37] <archivist> zeeshan|2, their pricing v weight is suspect, try another seller
[11:50:39] <zeeshan|2> that whole region is surrounded by amassive trench?
[11:50:50] <CaptHindsight> ssi: was that pic your planes reflection off the spaceship? :)
[11:50:57] <zeeshan|2> archivist: they are cheap though
[11:50:59] <zeeshan|2> so id like to get it from them
[11:51:02] <zeeshan|2> and they are local
[11:51:17] <zeeshan|2> http://www.busybeetools.com/products/v-block-5in.html
[11:51:20] <zeeshan|2> this is their largest v-block
[11:51:24] <archivist> zeeshan|2, the 39$ are lighter and smaller...odd
[11:51:30] <zeeshan|2> lol
[11:51:34] <ganzuul> zeeshan|2: That was one of the intepretations. You said you wanted less math earlier, so an impressionistic intepretation is an alternative to that. Experimental approaches are thorough but require hard work; e.g. how laser deplete local entropy to align and synchronize photons
[11:51:53] <ssi> CaptHindsight: eh?
[11:52:28] <malcom2073> furrywolf: I think you were talking to me, and fwiw, I have 1.5mbit down, and 256kbit up.
[11:52:42] <CaptHindsight> ssi: Bermuda triangle stories
[11:52:47] <archivist> zeeshan-lab, look at the dimensions and weight of http://www.busybeetools.com/products/v-block-5in.html
[11:52:47] <furrywolf> see, ten times faster than mine. :P
[11:52:54] <zeeshan|2> archivist: yes i see what you mean
[11:52:55] <zeeshan|2> scam!
[11:52:59] <malcom2073> We're also extremly heavily in the minority
[11:53:05] <malcom2073> Possibly majority in this channel though :P
[11:53:06] <archivist> dont trustem
[11:53:15] <furrywolf> and I'm one of the lucky people who has 250-ish kbit, not dialup. :P
[11:53:17] <archivist> web 2 error
[11:53:24] <zeeshan|2> i think there is error
[11:53:24] <furrywolf> and my latency is only 300ms, not 1000ms like the people on satellite. :P
[11:53:29] <zeeshan|2> look at the weight listed for v-block 4
[11:53:30] <zeeshan|2> its 2.25kg
[11:53:35] <zeeshan|2> for v-block 5 its 3.2 kg
[11:53:51] <archivist> they are confused
[11:54:12] <zeeshan|2> that 3" is a typo for sure
[11:54:14] <zeeshan|2> its prolly 5"
[11:54:16] <archivist> you may get discount for informing them
[11:54:40] <zeeshan|2> i dont understand why they just list the overall dimensions
[11:54:49] <zeeshan|2> and dont list he most important dimension
[11:54:51] <zeeshan|2> vblock capacity!!

[11:59:07] <archivist> I am in the UK and on the slow adsl
[11:59:15] <zeeshan|2> http://pastebin.com/2aZr4HJH
[11:59:25] <zeeshan|2> if my table has this type of deviation along its travel
[11:59:26] <furrywolf> yes. this is 3g. 3g, or anything g, is worse than adsl, or anything dsl. :P
[11:59:54] <zeeshan|2> and i was facing a component like this with a face mill:
[12:00:32] <archivist> my old mill produced a saw tooth form with a face mill
[12:00:41] <zeeshan|2> http://i.imgur.com/lg6Bt4O.png
[12:00:50] <zeeshan|2> note the flange is mounted sideways
[12:00:56] <zeeshan|2> would the flange surface still be flat
[12:01:04] <zeeshan|2> but slightly angled
[12:01:05] <zeeshan|2> thats it?
[12:01:21] <zeeshan|2> (thats my logic! :P)
[12:01:35] <zeeshan|2> youre basically machining an angle on the surface
[12:01:39] <zeeshan|2> but it should still be flat..
[12:01:58] <archivist> if the face mill covers the width then ok
[12:02:15] <zeeshan|2> yes
[12:02:24] <zeeshan|2> but if i moved it, i guess it makes sense
[12:02:28] <zeeshan|2> that it would no longer be coplanar
[12:02:35] <zeeshan|2> well would it?
[12:02:35] <archivist> exactly
[12:02:36] <furrywolf> zeeshan-lab: obviously your mill is unusable. I'll do you a favor and head up there with a truck and haul it off for you, save you the work of scrapping it.
[12:02:47] <malcom2073> haha
[12:02:52] <archivist> hey thats mine first!
[12:03:14] <archivist> I am swapping for my V blocks
[12:03:32] <ganzuul> Noob question: Why don't people make their own v-blocks and 1-2-3s etc?
[12:03:35] <furrywolf> are the units thous?
[12:03:36] <zeeshan|2> damn it the flange is 2.62" wide
[12:03:42] <zeeshan|2> ganzuul: cause its cheap to buy them
[12:03:50] <furrywolf> ganzuul: you can buy them pre-made cheaper than you can buy the stock to make them
[12:03:50] <zeeshan|2> furrywolf: yes
[12:03:55] <archivist> ganzuul, it is a good exercise, go make some
[12:04:07] <furrywolf> and what percentage of the table does your flange cover?
[12:04:11] <zeeshan|2> all
[12:04:12] <zeeshan|2> :-)
[12:04:18] <zeeshan|2> cause it's mounted on a diagonal
[12:04:24] <furrywolf> and how thick is your exhaust gasket? :P
[12:04:34] <zeeshan|2> 3 thou aint gonna do shit
[12:04:36] <ganzuul> I figured you could score some scrap and make 'em out of that...
[12:04:36] <zeeshan|2> to an exhaust gasket
[12:04:43] <zeeshan|2> especially if its flat
[12:04:44] <malcom2073> That reminds me, I havea kurt vice on the mill at work. I stuck a piece of bar stock on it and measured along its length,it seems the vice is at a slight angle, but has no play (since it fits in the table slots) to adjust. How do I straighten that?
[12:04:44] <archivist> then fly cut if you can at full width
[12:04:48] <furrywolf> and will you even notice your exhaust pointing 3 thous sideways? :P
[12:05:00] <zeeshan|2> furrywolf: no
[12:05:05] <zeeshan|2> but i will definitely notice if its not flat
[12:05:07] <furrywolf> then get machining. :)
[12:05:12] <zeeshan|2> cause id like to use a multilayer metal gasket
[12:05:18] <zeeshan|2> not composite
[12:05:43] <furrywolf> if the problem is just the table's tilted, the results will be the same as if you mounted the flange at a slight angle - slightly wedge shaped.
[12:06:11] <zeeshan|2> we need a module for linuxcnc
[12:06:17] <archivist> malcom2073, check for bumps and dents first, might just need cleaning them up
[12:06:17] <zeeshan|2> that interpolates table errors !:P
[12:06:20] <zeeshan|2> instead of fixing the problem
[12:06:20] <ganzuul> Oh! And why don't people re-melt their own chips? Is it some kind of standards thing?
[12:06:22] <furrywolf> there is a module for linuxcnc
[12:06:25] <zeeshan|2> compensate :P
[12:06:30] <furrywolf> that interpolates table errors
[12:06:30] <zeeshan|2> there is?
[12:06:32] <furrywolf> and compensates
[12:06:36] <furrywolf> yes :P
[12:06:38] <zeeshan|2> name
[12:06:38] <zeeshan|2> link
[12:06:39] <zeeshan|2> address
[12:06:44] <malcom2073> archivist: Ah true, I'll double check to make sure the slots are really clean adn smooth ,same with the ridges on the underside of the kurt
[12:06:45] <furrywolf> don't remember.
[12:06:50] <archivist> zeeshan|2, stuart fixed his cinci with the kins
[12:07:01] <furrywolf> you give it a map of points and offsets, and it does fancy triangular interpolation.
[12:07:03] <malcom2073> sorry not tilted, but rotated
[12:07:16] <zeeshan|2> it should really need the values i have listed
[12:07:17] <zeeshan|2> to figure it out
[12:07:18] <furrywolf> it was originally intended for pcb milling, where being off by a few thous across a wide board might cause issues.
[12:07:20] <zeeshan|2> cause it is a linear error
[12:07:55] <archivist> nothing is exact, the amount of error may or may not be in spec
[12:08:15] <furrywolf> but, really, at 3 thous across your whole table, I'd label it not a problem.
[12:08:22] <zeeshan|2> it bothers me
[12:08:25] <zeeshan|2> cause things arent flat :P
[12:08:34] <furrywolf> if you need things flatter than that, get a surface grinder. :)
[12:08:43] <zeeshan|2> and people who own this machine have suggested what to do
[12:08:45] <zeeshan|2> but its quite involved
[12:08:55] <furrywolf> mount a sheet of aluminum on top of the table and face-mill it flat.
[12:09:09] <zeeshan|2> a mill should do 0.0005 flatness
[12:09:10] <zeeshan|2> no problem
[12:09:14] <zeeshan|2> what kind of solution is that
[12:09:14] <zeeshan|2> lol
[12:09:35] <zeeshan|2> furrywolf: that is a good solution actually
[12:09:40] <furrywolf> if you use the mill to face-mill it flat, it'll be perfect relative to the head, regardless of the table.
[12:09:41] <zeeshan|2> would be less work
[12:10:02] <furrywolf> also, make sure you're not just on an unlevel base or something. try sticking a shim under the low corner of the machine. :P
[12:10:25] <archivist> may be better to fix or adjust the slides
[12:10:34] <zeeshan|2> the slides arent out
[12:10:41] <zeeshan|2> its the mating of the table they suspect
[12:10:52] <archivist> the error proves otherwise :)
[12:10:54] <zeeshan|2> http://i.imgur.com/cr6IPoY.jpg
[12:10:59] <zeeshan|2> http://i.imgur.com/yuBBs6Y.jpg
[12:11:17] * furrywolf wonders who "they" is
[12:11:30] <zeeshan|2> archivist: i did different tests to come to that conclusion
[12:11:36] <zeeshan|2> if it was the ways, i woulda seen it!
[12:11:44] <zeeshan|2> i jogged the Z up and down
[12:11:50] <zeeshan|2> with a square on the table
[12:12:03] <zeeshan|2> and it reads 0 in both ZY and ZX planes
[12:12:57] <archivist> that implies the table can be hanging forward, wear top rear and bottom front of the z slide
[12:12:59] <furrywolf> I have no idea how level my machine is. It got knocked over with a forklift and fell hard. my plan is to pretend it's perfect until I make some part that actually doesn't work. :P
[12:13:07] <zeeshan|2> no the table is higher from the front
[12:13:27] <zeeshan|2> 1. table is perpendicular to column within 0.0002"
[12:13:35] <zeeshan|2> 2. Y axis is not parallel to table. The way I check this is by mounting a mag base to the quill and then jogging around the table. the error is shown here:
[12:13:41] <zeeshan|2> (see the pastebin link)
[12:13:50] <zeeshan|2> according to this check, the Y axis is out by -0.003" (last time i got ~0.0025", but i only did one measurement, this time i repeated this measured 3 times to get confidence)
[12:14:04] <zeeshan|2> 3. quill is perpendicular to the table within 0.0001". however, it is not parallel to the column. I get an error of +0.0015. Visually this looks like (side view):
[12:14:17] <zeeshan|2> 4. The vertical to horiziontal spindle mount is perpendicular to the table within 0.0004"
[12:14:37] <zeeshan|2> so i think the Y axis droops down a bit
[12:14:43] <zeeshan|2> but most of the error comes from the table mounting
[12:15:04] <zeeshan|2> im gonna redo the table map for different Z heights
[12:15:06] <zeeshan|2> and see if its consistent
[12:15:22] <zeeshan|2> if it is, i can compensate for the error by scraping the table mounting
[12:15:32] <zeeshan|2> or just add a layuer of aluminum like furry suggested :)
[12:15:58] <furrywolf> or make chips. :P
[12:16:10] <furrywolf> and only deal with it if you actually have a part that needs that tolerance.
[12:16:10] <archivist> front heavy mills wear the Z slides
[12:17:25] <zeeshan|2> archivist: if z slide is worn
[12:17:31] <zeeshan|2> then i should see different numbers
[12:17:34] <zeeshan|2> for the table map
[12:17:38] <zeeshan|2> at diff z heights, right?
[12:18:17] <archivist> depends if the jacking screw is in front or side of CG
[12:18:33] <archivist> and where the wear is
[12:18:34] <furrywolf> what order are your slides stack? Z, X, Y, right?
[12:18:36] <furrywolf> stacked
[12:19:00] <zeeshan|2> archivist: the table map covers all regions of travel
[12:19:00] <furrywolf> or Z, Y, X, actually
[12:19:03] * furrywolf is tired
[12:19:04] <zeeshan|2> so it should show
[12:19:24] <zeeshan|2> what do you mean by slides stack?
[12:19:31] <furrywolf> tried tightening your gibs, especially Z?
[12:19:33] <archivist> you are not getting the bending moment of the jacking screw
[12:19:38] <furrywolf> what's the play in the table like?
[12:19:52] <zeeshan|2> i dont feel any play :/
[12:20:02] <zeeshan|2> but the table is also 250lb
[12:20:06] <zeeshan|2> or more
[12:20:07] <zeeshan|2> :P
[12:20:09] <archivist> it is heave, measure dont feel play
[12:20:11] <zeeshan|2> so i cant really move it that will
[12:20:12] <ssi> put a dti on it and measure it
[12:20:20] <furrywolf> if the Z gibs were a little loose, moving the table around could be causing it to tilt back and forth slightly
[12:20:20] <zeeshan|2> oh that
[12:20:21] <zeeshan|2> i did that
[12:20:28] <zeeshan|2> i tried lifting the table with all i got
[12:20:30] <zeeshan|2> and i couldnt move it
[12:20:33] <zeeshan|2> (the dti)
[12:20:37] <furrywolf> ... 25 lbs.
[12:20:39] <furrywolf> :P
[12:20:42] <zeeshan|2> :]
[12:21:07] <zeeshan|2> this machine only has 2000 hours on it
[12:21:17] <zeeshan|2> im pretty sure osmeone mounted the table
[12:21:22] <zeeshan|2> and didnt clean the interface
[12:21:32] <furrywolf> heh, for lifting heavy things... I once watched a guy pick up and carry around a toyota v6 with tranny and t-case.
[12:21:41] <zeeshan|2> cause the table is meant to come off for different accessories
[12:21:44] <archivist> you can also see a rock on a dti when you do an axis reversal
[12:22:00] <zeeshan|2> archivist: when jogging up and down?
[12:22:19] <archivist> and left right front back/whatever
[12:23:00] <archivist> place dti as far from centre as possible on a flat
[12:23:49] <archivist> it is time the Schlesinger testing machine tools book was online
[12:24:38] <furrywolf> the way it looks to me like your machine is built, unless the table were machined crooked, your measurements are odd... for X moves, only the table is moving, right?
[12:25:49] <zeeshan|2> furrywolf: yep
[12:26:00] <zeeshan|2> the table can come off using 6 bolts
[12:26:05] <zeeshan|2> there is a "Vertical" table
[12:26:11] <zeeshan|2> that is mounted to the X axis
[12:26:29] <zeeshan|2> this is an accurate surface
[12:26:32] <furrywolf> so then unless the table was machined as a wedge, wouldn't any changes in height during X-only movements have to be slop somewhere?
[12:26:33] <zeeshan|2> where you can mount a rotartary table
[12:26:35] <zeeshan|2> hirizontal table
[12:26:36] <zeeshan|2> etc
[12:26:53] <zeeshan|2> furrywolf: if somoene took of the table to use a rotary tablle for example
[12:27:01] <zeeshan|2> and mounted it back so there were chips behind it
[12:27:04] <zeeshan|2> it could cause this error
[12:27:15] <zeeshan|2> i need to do one obvious test that i didnt do
[12:27:28] <zeeshan|2> mount a indicator in the spindle and rotate the spindle and measure the table
[12:27:37] <zeeshan|2> and see if i get the same error in the +y -y regions
[12:27:37] <furrywolf> oh, so the table is in two parts, one that actually has the x-axis ways, and one that mounts to that, that has the t-slots?
[12:27:46] <zeeshan|2> furrywolf: yep
[12:27:54] <furrywolf> so take it apart, clean/shim it, put back together?
[12:28:09] <zeeshan|2> i will do all that work when im damn sure about the error
[12:28:13] <zeeshan|2> its quite heavy :)
[12:28:20] <zeeshan|2> and ill have to go buy eye bolts
[12:28:25] <zeeshan|2> they are metric scum :p
[12:28:39] <furrywolf> another possibility is you just have slop in your gibs somewhere, and when the weight moves to the other side of the machine, they're tilting a few thous. :P
[12:28:57] <zeeshan|2> a static sweep like i descrived a sec ago
[12:28:59] <zeeshan|2> should verify that
[12:29:21] <zeeshan|2> if its still out while the machine is as centered as possible
[12:29:32] <zeeshan|2> that almost positively shows that the table is not square
[12:29:55] <furrywolf> put a dial indicator somewhere off to the side of the machine, from head to the table, with the table all the way to one side, and apply >250lbs of force up/down to the table.
[12:31:15] <furrywolf> I'm sure you have a car jack or other device capable of applying force. :)
[12:33:07] <zeeshan|2> no
[12:33:13] <zeeshan|2> i usually just lift the car with my strength
[12:33:46] <archivist> if I tighten the gibs on my horizontal I cannot do a full traverse it is that worn, ex boss claimed it was almost new!
[12:34:55] <zeeshan|2> haha
[12:35:29] <furrywolf> I got an electric car jack a couple weeks ago. I love it.
[12:35:39] <archivist> ew lazy :)
[12:35:50] <furrywolf> presumably one of these days my back will stop hurting, and then it won't be as useful...
[12:37:36] <furrywolf> http://www.amazon.com/Electric-Scissor-Auto-Jack-Lift/dp/B000P0RP0I just one of those, nothing fancy.
[12:37:47] <furrywolf> I was surprised that it actually has limit switches.
[12:38:10] <zeeshan|2> nice
[12:38:11] <zeeshan|2> lol
[12:40:43] <PetefromTn_> They wanted to put Chuck Norris' face on Mt. Rushmore.......but apparently the granite was not hard enough for his beard LOL
[12:42:06] <zeeshan|2> haha
[12:43:04] <PetefromTn_> Apparently Chuck Norris' Tears actually cure Cancer......only problem is that he never cries...EVER!! ;)
[12:44:08] <furrywolf> only problem with that jack is now that I lifted my car, I have to stick the jack on a block of wood. :)
[12:44:18] <PetefromTn_> That electric jack is actually pretty cool....too bad it is not a big strong bottle jack
[12:46:00] <furrywolf> works fine for lifting my subaru. :)
[12:49:15] <PetefromTn_> well sure whats it weigh about 50or60 lbs?
[12:49:28] <furrywolf> lol
[12:49:35] <furrywolf> 2200ish
[12:49:45] <PetefromTn_> :D
[12:50:44] <archivist> zeeshan|2, you were going to get a machinists level, now is the time to use it to check the table error
[12:51:49] <zeeshan|2> i have one
[12:51:52] <zeeshan|2> i did level the machine
[12:52:55] <PetefromTn_> You got every measuring tool known to man and are trying to sell spares and you can't get that thing sorted???!! Just kidding man...
[12:53:04] <furrywolf> PetefromTn_: http://www.hiwtc.com/products/electric-car-jack-electric-hoisting-jack-hydraulic-jack-2051-73079.htm electric screw jack, bottle jack style.
[12:53:29] <PetefromTn_> cool
[12:54:17] <archivist> zeeshan|2, place it on the table, traverse the table, does the level change, yes then an error
[12:55:41] <furrywolf> you have a level that will show a few thous change over three feet? I want one. :P
[12:56:04] <zeeshan|2> furrywolf: they are common
[12:56:04] <zeeshan|2> :P
[12:56:15] <furrywolf> not here!
[12:56:16] <zeeshan|2> most machinist level will do that
[12:56:25] <zeeshan|2> look up starrett #98
[12:56:34] <furrywolf> of course, there's no machinist tools for sale here, only carpenter's tools...
[12:56:39] <FinboySlick> Tom Lipton showed a pretty amazing differential level on one of his recent videos.
[12:56:50] <zeeshan|2> FinboySlick: yes it is bad ass
[12:56:52] <archivist> gnats cock per yard per div
[12:56:57] <furrywolf> and a thou a foot is a lot tighter than anyone here builds houses to. :)
[12:58:46] <archivist> and turn your level 90 degrees and traverse again
[12:59:01] <zeeshan|2> i wanna do the Z check
[12:59:05] <zeeshan|2> at different Z heights
[12:59:09] <zeeshan|2> gonna do that in a few min
[12:59:15] <zeeshan|2> just finishing up some school work :P
[13:00:48] <furrywolf> don't you get a summer vacation? or is there no summer in canada? :P
[13:01:06] <zeeshan|2> no summer vac :/
[13:01:09] <archivist> constant winter I though
[13:02:00] <furrywolf> yeah, I don't think they get a summer vacation since they don't have a summer...
[13:05:51] * FinboySlick saw a Datron C5 and fell in love.
[13:06:13] <archivist> Sinclair C5 ?
[13:06:49] <FinboySlick> What is that, some sort of british joke? ;)
[13:07:23] <archivist> absolutely https://en.wikipedia.org/wiki/Sinclair_C5
[13:07:34] <FinboySlick> Yeah, I looked it up.
[13:07:55] <archivist> not one of his finest ideas
[13:08:13] <FinboySlick> Do have a peek at the Datron though.
[13:10:52] <archivist> I have seen this style in the flesh at the local machine show
[13:11:50] <archivist> for some work the need exceedingly long slender tooling and therefore small cuts
[13:11:54] <FinboySlick> I find the trunion pretty high though. I figure it's to fit the table rotation motor but it seems like useless stress on the pivot to me.
[13:12:30] <FinboySlick> I'm sure it could have been made much more compact.
[13:15:39] <archivist> there is another version with vertical spindle and more stacked rotaries, one at 45 deg
[13:16:57] <archivist> cannot remember who made it
[13:19:20] <CaptHindsight> is there a small tabletop mill that not complete rubbish for milling polypropylene? http://www.ebay.com/itm/3-Axis-CNC-Router-Engraver-3020T-Engraving-Drilling-Milling-Machine-USA-/301114608328
[13:20:03] <FinboySlick> Wow, that's cheap.
[13:20:14] <FinboySlick> Then again, it might not even be worth its price.
[13:20:36] <archivist> more important can those little things carry the required dust/swarf extraction
[13:20:40] <CaptHindsight> if it's anything like the others I had to rework
[13:20:51] * furrywolf wonders if a datron c5 is anything like a daystrom m5
[13:20:57] <CaptHindsight> shopvac adapter
[13:21:22] <CaptHindsight> or air knife
[13:22:22] <zeeshan-mill> just moved to Z 0
[13:22:23] <CaptHindsight> it just needs to mill ~1/4" PP sheet up to maybe 4 x 5"
[13:22:28] <just_pink> really cheap.
[13:22:38] <zeeshan-mill> and and jogged in xy table plane, got the same profile as
[13:22:42] <zeeshan-mill> when the z is at max travel
[13:22:51] <zeeshan-mill> proof its the table :P
[13:23:03] <zeeshan-mill> actually not 100% proof
[13:23:08] <zeeshan-mill> but getting closer :P
[13:23:41] <CaptHindsight> going to make PP patterns for casting gummys, chocolates, icing etc
[13:24:40] <FinboySlick> zeeshan-mill: What sort of problem is it? If you face a plate it doesn't have even thickness?
[13:24:40] <CaptHindsight> https://www.youtube.com/watch?v=qrypdAGEZBg&feature=youtu.be&t=1m58s
[13:25:15] <just_pink> CaptHindsight: for casting you can work with wax
[13:25:30] <furrywolf> bbl
[13:26:15] <zeeshan-mill> FinboySlick, trying to figure the problem still :P
[13:26:15] <CaptHindsight> food grade wax pattern with corn starch molds
[13:26:26] <zeeshan-mill> FinboySlick, i sweep the table
[13:26:30] <zeeshan-mill> and it looks like my pastebin kink
[13:26:32] <zeeshan-mill> *link
[13:27:06] <CaptHindsight> for low volume wax might be better
[13:27:46] <CaptHindsight> or a food gum
[13:28:16] <PetefromTn_> coated with mineral oil??
[13:28:25] <CaptHindsight> no oil
[13:28:53] <PetefromTn_> thats what it said in the video
[13:29:51] <CaptHindsight> PetefromTn_: oh for the shiny finish
[13:29:53] <just_pink> Ihear that too
[13:30:22] <PetefromTn_> surely there is some other goo they can spray on em for a shiny finish
[13:30:26] <CaptHindsight> or sour mix
[13:30:49] <FinboySlick> zeeshan-mill: http://www.kennametal.com/content/dam/kennametal/kennametal/common/Products/Metalworking/Indexable%20Milling/Face%20Mills/KSRM_Daisy_Group_Inserts.jpg and mill the table flat! ;)
[13:31:02] <PetefromTn_> remind me to NOT eat any more Gummy candy
[13:31:05] <FinboySlick> That's the brute-force solution.
[13:31:21] <SpeedEvil> http://boxofrocks.com/
[13:31:25] <PetefromTn_> I like that facemill...
[13:31:33] <CaptHindsight> plus there are other formulas like Twizzlers, the oil knocks off the corn starch
[13:32:25] <PetefromTn_> yeeeuuukk
[13:32:29] <CaptHindsight> heh, mineral oil for the older crowd, and fish oils for the Gunmmy Sushi Fish
[13:32:35] <just_pink> PetefromTn_: I think I'm eat much more cutting oil than few drop of mineral oil on the gummys..
[13:32:52] <CaptHindsight> cod liver
[13:33:06] <PetefromTn_> few drops? Did you see the spray nozzle?
[13:33:10] <CaptHindsight> there must be >100 oils and fats to choose from
[13:33:26] <PetefromTn_> CaptHindsight yeah and some more healthy to eat surely
[13:34:02] <PetefromTn_> I mean I got a can of mineral oil out in the shop but I don't plan on drinking it any time soon....at least not while I am sane anyways ;)
[13:34:10] <just_pink> the nozzle is for the whole drum..
[13:34:12] <CaptHindsight> Olestra slides right through
[13:34:18] <zeeshan-mill> haha fenn
[13:34:20] <zeeshan-mill> FinboySlick, i mean :P
[13:34:43] <PetefromTn_> just_pink for the record you are not supposed to EAT the cutting fluids... that is kinda frowned on :D
[13:34:50] <ganzuul> doood
[13:34:57] <ganzuul> Titanium is expensive.
[13:35:07] <PetefromTn_> sure as hell is
[13:35:20] * ganzuul wants it anyway
[13:36:19] <PetefromTn_> me too hehe
[13:36:49] <PetefromTn_> I swear I must come across as quite a smartass here. Wonder how true that is....
[13:37:24] <ganzuul> eh. internet standards aren't high
[13:37:46] <FinboySlick> PetefromTn_: Well, take comfort in the fact that I'm around as a 'worse than Pete' option.
[13:38:10] <PetefromTn_> CaptHindsight I am setting up that Cast Iron plate job right now on the machine. Got to pickup several datum points for locations of the holes and then I will take a peck at it
[13:38:29] <PetefromTn_> FinboySlick LOL you are TAME in comparison man
[13:39:04] <PetefromTn_> Worst I ever saw here that is STILL here has gotta be Zeeshan ;)
[13:39:44] <FinboySlick> Maybe we all tolerate zeeshan because we're mildly jealous of his toys.
[13:39:57] <PetefromTn_> what toys?
[13:40:09] <FinboySlick> Even his uneven mill is better than my uneven mill :P
[13:40:19] <PetefromTn_> hehe
[13:40:41] <PetefromTn_> The only thing he has that I would want is that damn RX7 and he pulled out the best part ;)
[13:40:42] <FinboySlick> Doesn't he have a lathe too? That's got you covered, Pete.
[13:41:13] <PetefromTn_> Meh I sold that lathe because I wanted the one I have.....but I wish I could have kept it AND gotten this lathe
[13:41:45] <FinboySlick> PetefromTn_: Are you saying his RX7 doesn't have a wankel?
[13:42:16] <PetefromTn_> That is EXACTLY what I am saying
[13:42:41] <FinboySlick> But without a wankel, all a RX-7 has left is the wanker driving it.
[13:44:03] <PetefromTn_> heh
[13:44:29] <PetefromTn_> honestly thats not fair it is a good looking car with a pretty damn good suspension setup really
[13:44:31] <skunkworks> turbo in -> apex seals out ->
[13:45:59] <PetefromTn_> damn man I need some more 123 blocks
[13:47:27] <just_pink> someone know how to calculate the correct distance between the electrode to the material?
[13:47:41] <archivist> mine are jacking up my B axis
[13:47:59] <PetefromTn_> B? woah
[13:48:16] <archivist> just_pink, in a battery, anodising vat?
[13:48:20] <zeeshan|2> FinboySlick: shuddap
[13:48:38] <just_pink> archivist: EDM
[13:48:40] <FinboySlick> zeeshan|2: Hey, you did it, you earned it ;)
[13:48:53] <PetefromTn_> wanker?
[13:49:09] <archivist> PetefromTn_, can just see the edges http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_11_bevel/IMG_1635.JPG
[13:50:38] <archivist> had to get it up in the air to spin A properly
[13:50:51] <PetefromTn_> that thing is way out there in space man no?
[13:51:42] <archivist> just_pink, remember EDM is in fluid and sparks, the gap is varied to enable the sparks
[13:52:51] <archivist> PetefromTn_, 4" up in space iirc
[13:54:47] <zeeshan|2> http://pastebin.com/3eADx8QB
[13:54:53] <zeeshan|2> here is more results from measuring
[13:54:57] <zeeshan|2> when i sweep
[13:55:04] <zeeshan|2> so none of the axis are moving
[13:55:08] <zeeshan|2> i get these results!
[13:55:22] <FinboySlick> You're making it worse!
[13:56:34] <archivist> a level will show any curve of the ways
[13:57:00] <archivist> + on the indicator means what
[13:57:09] <zeeshan|2> high
[13:57:53] <PetefromTn_> what adjustments does the table have?
[13:57:59] <zeeshan|2> none :)
[13:58:03] <archivist> and your Y is on the column so as it moves forward can bend downwards more
[13:58:15] <just_pink> archivist: I know it's under oil, but I need to keep the same distance all the time (except of the finish pass)
[13:59:22] <archivist> just_pink, real machines plunge they dont traverse, except for wire edm
[14:00:00] <archivist> the contact current /voltage is measured to move closer/further in a loop
[14:00:58] <archivist> not the right technique to strip the rear of a pcb :)
[14:01:44] <just_pink> archivist: you cought me..
[14:02:04] <archivist> I do remember things :)
[14:02:27] <just_pink> but
[14:02:32] <zeeshan|2> archivist: the sweep test
[14:03:01] <zeeshan|2> i guess i need to figure out how to isolate the Y droop
[14:03:07] <just_pink> I have much beigger problem with the pcb - half of the LEDs from ebay not working.
[14:03:17] <archivist> just_pink, cover one side in resist, dip in ferric chloride
[14:03:42] <just_pink> archivist: It's too normal..
[14:03:43] <zeeshan|2> archivist: do you know how to adjust the Y axis gibs?
[14:03:59] <zeeshan|2> its not obvious t ome
[14:04:01] <archivist> zeeshan|2, a level on the head should spot that
[14:04:48] <zeeshan|2> couldnt i do it more definitively
[14:04:55] <zeeshan|2> like by mounting the mag base to the table
[14:04:55] <archivist> I dont have the mikron manual for that!
[14:05:00] <zeeshan|2> and measuring the Y ways
[14:05:15] <zeeshan|2> well i think must be an euro style thing
[14:05:32] <zeeshan|2> actually im gonna do do that
[14:05:37] <zeeshan|2> measure the Y ways directly
[14:05:48] <zeeshan|2> by mounting the mag base to the stationary table
[14:05:50] <zeeshan|2> should show this error
[14:06:32] <archivist> does it have taper gibs with a screw at each end
[14:07:00] <zeeshan-mill> yea its a big dove tail
[14:07:04] <zeeshan-mill> but i cant see where the gib is
[14:07:32] <archivist> I have seen one where it moves the main bed casting
[14:07:55] <archivist> my sliding head is strange
[14:09:41] <Tom_itx> archivist, keep it fixed to your shoulders
[14:09:45] <archivist> some have both closing and jacking apart screws to adjust, I hate them
[14:10:43] <archivist> too much crap on the lathe to get a pic of its adjustment
[14:11:22] <zeeshan-mill> archivist hi
[14:11:31] <zeeshan-mill> lemme take a pic
[14:12:29] <zeeshan-mill> 0.0003 in 9"
[14:12:43] <zeeshan-mill> when mounting mag base to table, and indicating the Y way
[14:12:53] <zeeshan-mill> so its not y axis drooping down
[14:18:36] <zeeshan-mill> with base mounted to Z way , and square on table
[14:18:43] <zeeshan-mill> 0.0004 in 8"
[14:18:55] <zeeshan-mill> sigh!!
[14:19:32] <archivist> remember the flat on the way is not the V on that same way
[14:20:16] <archivist> adjust gibs see if it gets better
[14:20:50] <zeeshan-mill> ill measure the v
[14:20:54] <zeeshan-mill> with a test indicator
[14:22:19] <zeeshan-mill> same thing
[14:22:25] <zeeshan-mill> now its actually better
[14:22:35] <zeeshan-mill> 0.0001 over 9"
[14:23:03] <Tom_itx> or are you measuring dirt on the ways?
[14:23:06] <zeeshan-mill> why will tightening the gibs do anything?
[14:23:15] <zeeshan-mill> the y axis isnt drooping
[14:23:21] <archivist> just take off the table clean behind remount
[14:23:26] <zeeshan-mill> yes!
[14:23:29] <zeeshan-mill> that suggestion makes more sense
[14:23:33] <zeeshan-mill> but its a lot of work!!
[14:23:37] <zeeshan-mill> (heavy work!)
[14:23:41] <Tom_itx> you like work
[14:23:47] <archivist> is it done yet?
[14:23:50] <zeeshan-mill> hahaha
[14:23:52] <Tom_itx> heavy grunt work
[14:23:58] * Tom_itx cracks the whip
[14:24:08] <zeeshan-mill> im trying to measure the threaded hole loctions
[14:24:13] <zeeshan-mill> i need to by eye bolts
[14:24:21] <archivist> her indoors will give you a lift
[14:26:46] <zeeshan-mill> guess what
[14:26:57] <zeeshan-mill> looked in the scrap pile from the elec cabinet
[14:27:06] <zeeshan-mill> eye bolts in there :D
[14:30:34] <PetefromTn_> surely there has got to be SOME sort of adjustment in the machine to square it to the table. I mean I know the bavarians are so meticulous but jeez what are the odds of getting the castings perfect the first time?
[14:30:57] <zeeshan-mill> pete everyting is hand srapped
[14:30:59] <zeeshan-mill> scraped
[14:31:02] <archivist> one adjusts the castings!
[14:31:04] <PetefromTn_> BS
[14:31:07] <zeeshan-mill> it is
[14:31:17] <zeeshan-mill> its not a bridgeport :P
[14:31:27] <zeeshan-mill> these euros are crazy
[14:31:35] <PetefromTn_> sorry not buyin' it
[14:31:46] <zeeshan-mill> just look up deckel online
[14:31:47] <zeeshan-mill> ull see
[14:31:53] <archivist> this old method is very real
[14:32:02] <PetefromTn_> if it is so damn good and the machine is not that old how come it is so far out?
[14:32:18] <archivist> he doin it wrong :)
[14:32:37] <zeeshan-mill> im looking at the vertical tabl
[14:32:43] <zeeshan-mill> the key in it looks not factory
[14:32:59] <archivist> crap in the table mount is a prime suspect
[14:33:01] <zeeshan-mill> someone definitely had this apart
[14:33:06] <zeeshan-mill> this makes sense now
[14:33:11] <zeeshan-mill> why i had 4 servo drive cards
[14:33:15] <zeeshan-mill> and one wasnt connected
[14:33:33] <zeeshan-mill> they likely had the rotary axis table option for this
[14:34:25] <zeeshan-mill> LOL
[14:34:33] <zeeshan-mill> the top bolt is LOOSE
[14:34:48] <zeeshan-mill> on the one side of 3 bolts
[14:35:14] * archivist hands zeeshan-mill a mirror to look at the culprit
[14:35:35] <zeeshan-mill> i don think its the reason
[14:35:40] <zeeshan-mill> but im almost damn sure somoene has this table off
[14:35:52] <zeeshan-mill> archivist, give me superman vision
[14:35:56] <zeeshan-mill> so i can see through the metal
[14:37:46] <archivist> nothing beats looking the other side after taking bits off :)
[14:37:47] <zeeshan-mill> ofcourse, i only got 3 out of 4 eye bolts i need.
[14:37:48] <zeeshan-mill> =[
[14:37:57] <zeeshan-mill> yea
[14:38:27] <zeeshan-mill> im gonna have to move my metal stock and a whole bunch of shit
[14:38:31] <zeeshan-mill> to be able to use the engine hoist
[14:38:50] <ganzuul> http://cncmanual.com/
[14:38:52] <FinboySlick> zeeshan-mill: Use 3 eye bolts, a normal bolt and steel-capped boots.
[14:38:59] <archivist> shift that old car out
[14:39:11] <zeeshan-mill> FinboySlick, i dont think i have a single m12x1.75 bolt
[14:39:17] <zeeshan-mill> its not a common size for me
[14:39:20] <FinboySlick> archivist: Nah, the sheet metal should dampen the blow and save the table.
[14:39:51] <FinboySlick> It doesn't have a wankel anymore, it's all it's good for anyway.
[14:40:01] <zeeshan-mill> lol archivist
[14:40:01] <archivist> we do have fun with his scrap car
[14:40:25] <zeeshan-mill> this thing is so much better than the pos wankel can be
[14:40:30] <zeeshan-mill> so i giggle when you guys troll
[14:40:31] <zeeshan-mill> :D
[14:40:58] <FinboySlick> Delusion, the one ailment one never wants to cure.
[14:41:01] <Tom_itx> those headers are worth more than the chassis
[14:41:53] <archivist> so how is this so valuable http://www.ebay.com/itm/Barber-Colman-Company-Industral-Metalworking-Gear-Hobber-New-Modern-Postcard-M59-/301705439109
[14:43:10] <Tom_itx> only to the seller
[14:44:06] <zeeshan-mill> haha
[14:44:08] <zeeshan-mill> fu tom
[14:44:56] <archivist> I cannot imagine something so "used" ever being the subject of a real postcard
[14:45:05] <FinboySlick> archivist: That's crazy.
[14:45:47] <PetefromTn_> Hey 3 bucks WIN
[14:46:24] <archivist> I have barber colman in my watch list, those keep coming up, never sells any
[14:46:41] <CaptHindsight> "having a wonderful time, wish you were here"
[14:47:35] <archivist> got covered in oil
[14:52:55] <PetefromTn_> Active shooter in Nashville Movie Theater...apparently the cops killed him pretty quickly.
[14:54:42] <_methods> gotta wear body armor to the movies anymore
[14:54:51] <_methods> i wish they'd go back to shootin up post offices
[14:55:02] <PetefromTn_> hell I never hardly ever go to the movies anymore anyway
[14:55:16] <_methods> i guess no one goes to the post office anymore either lol
[14:56:03] <PetefromTn_> they said an officer entered the building and exchanged fire with the shooter and the officer retreated and moments later SWAT arrived and stormed the building and took him down.
[14:56:47] <zeeshan-mill> damn that is a beast
[14:56:58] <_methods> can't imagine a theater being too crowded on a wednesday afternoon
[14:57:07] <PetefromTn_> yeah thankfully
[14:57:23] <PetefromTn_> apparently he had a hatched and he injured one person with it.
[14:57:28] <PetefromTn_> hatchet
[14:57:38] <_methods> wtf
[14:57:48] <_methods> we need hatchet control
[14:57:52] <_methods> ban hatchets
[14:57:56] <PetefromTn_> ROFL
[14:58:06] <_methods> hehe
[14:58:11] <_methods> take em all off the shelves
[14:58:19] <_methods> walmart will be pullin all hatchets
[14:58:48] <Tom_itx> their hatchets are too dull to worry about it anyway
[14:58:49] <PetefromTn_> when I heard it was a hatchet I wondered if it was furrywolf hehe
[15:00:56] <FinboySlick> Question is, was this one on a prozzak derrivative too?
[15:01:12] <FinboySlick> Um, compared to other shooters that is.
[15:01:19] <FinboySlick> Not compared to furrywolf :P
[15:02:16] <PetefromTn_> don't care if he was on fruit loops he is dead now thankfully... coward that he was.
[15:05:03] <FinboySlick> PetefromTn_: I have a girl friend who was on that shit a while back. She described what it feels like to stop them and from what she told me, I have no problem understanding how it would drive someone to go on a shooting spree.
[15:13:22] <PetefromTn_> well either way it sounds like Nashville Police were quick and effective thankfully.
[15:20:34] <zeeshan|2> fak the eye bolts
[15:20:37] <zeeshan|2> did it my good old way
[15:20:47] <zeeshan|2> table is definitely around 300lb
[15:20:51] <zeeshan|2> feels like an engine block
[15:21:09] <zeeshan|2> http://imgur.com/a/gObpA
[15:21:38] <zeeshan|2> looks like whoever mounted the table had the table up one notch
[15:21:46] <zeeshan|2> im gonna lower it a bit and get more clearance!!
[15:35:43] <zeeshan|2> http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_11_bevel/IMG_1635.JPG
[15:35:49] <zeeshan|2> thats a pretty intricate setup archivist
[15:35:49] <zeeshan|2> :)
[15:36:14] <zeeshan|2> since you do fine stuff
[15:36:34] <zeeshan|2> how would you cut a 0.1 mm on a nozzle
[15:36:40] <zeeshan|2> 0.1 mm slit i mean.
[15:36:58] <FinboySlick> fine edm wire?
[15:37:12] <zeeshan|2> well i was thinking he would suggest a slitting saw
[15:37:16] <zeeshan|2> but thats so paper thing
[15:37:34] <zeeshan|2> http://homepage3.nifty.com/amigos/small_slotter/small_slotter-e.htm
[15:37:38] <zeeshan|2> this guy shows some 0.2 mm slitting saws
[15:37:48] <zeeshan|2> and even 0.1mm
[15:54:32] <MrSunshine> http://mdmetric.com/ this page realy contains a welth of information =)
[15:54:53] <MrSunshine> i thin kit was that page :P
[15:55:44] <MrSunshine> nah.. seems it was a tad off .. hmm
[15:55:57] <malcom2073> Nice, that place is really close to me
[15:56:25] <malcom2073> I love finding metric suppliers near me. There is a place called british metric very close which is nice, but they still have to order most stuff online
[15:57:24] <MrSunshine> heh =)
[15:57:41] <MrSunshine> i think it was that page that igot a wealth of info about thread depths and stuff on etc
[15:57:47] <MrSunshine> but cant seem to find them now ?
[16:05:38] <just_pink> MrSunshine: page is too yellow
[16:05:52] <MrSunshine> you are to pink
[16:08:50] <just_pink> MrSunshine: NO! the CNC is green,
[16:11:55] <MrSunshine> and blueberries are blue .. your point? :P
[16:13:15] <zeeshan|2> my god that yerllow background
[16:14:19] <just_pink> you have you use welding mask to use the website
[16:14:24] <XXCoder> hey 90s you forgot that site
[16:14:35] <zeeshan|2> just_pink: i agree!
[16:16:22] <just_pink> some one have an idea how to make thick spacer..
[16:16:29] <zeeshan|2> how thick
[16:16:37] <XXCoder> .001 LY
[16:16:37] <just_pink> 1/4''
[16:16:41] <zeeshan|2> got a lathe?
[16:16:47] <just_pink> no
[16:16:53] <just_pink> just VMC
[16:17:02] <zeeshan|2> got hole saws?
[16:17:11] <just_pink> no :(
[16:17:29] <zeeshan|2> why dont you just cut it out
[16:17:32] <zeeshan|2> of a sheet of 1/4"?
[16:17:36] <zeeshan|2> using circular interpolation
[16:17:42] <zeeshan|2> do the center hole first
[16:17:45] <zeeshan|2> then interpolate the outside
[16:17:53] <XXCoder> 1/4 inch is 6.71209866 × 10-19 ly lol
[16:18:03] <zeeshan|2> XXCoder: hahaha
[16:18:05] <zeeshan|2> nice way to look at it is
[16:18:07] <zeeshan|2> *it
[16:18:32] <just_pink> I forgot for a sec that i have a CNC..
[16:19:46] <zeeshan|2> just_pink: i notice a lot of people build cnc machines
[16:19:50] <zeeshan|2> but they dont know what to do with them after :P
[16:20:19] <just_pink> me too
[16:20:37] <Deejay> use the first cnc to build a second one
[16:20:39] <Deejay> :)
[16:20:48] <XXCoder> then repeat
[16:21:29] <jdh> <-
[16:21:30] <just_pink> LOL!!
[16:23:25] <XXCoder> I do have plans for my machine
[16:23:32] <XXCoder> that is, if I ever get to work on it lol
[16:24:01] <just_pink> why it's so complicated to solder stuff after you put hand lotion???
[16:24:33] <zeeshan|2> at least the people who build machines and dont know with them are still useful people
[16:24:51] <zeeshan|2> the average person is appauling
[16:26:14] <XXCoder> depends on where you are
[16:27:19] <zeeshan|2> well my definition of appauling should really be defined
[16:27:24] <zeeshan|2> people who can't change a lightbulb
[16:27:30] <zeeshan|2> people who feel entitled
[16:27:58] <zeeshan|2> :-)
[16:28:59] <XXCoder> I met one deaf guy like that
[16:29:19] <XXCoder> not "special" either, he just want to get money and watch tv
[16:29:42] <XXCoder> now, I understand ones that isn't smart enough to live on their own
[16:29:47] <zeeshan|2> he's deaf, not disabled.
[16:29:53] <zeeshan|2> theres plenty of stuff to do
[16:29:55] <XXCoder> well
[16:29:57] <XXCoder> thats what I said
[16:30:44] <XXCoder> it IS harder for deaf to get jobs
[16:30:52] <XXCoder> over 80% unemployed
[16:31:18] <zeeshan|2> why
[16:31:21] <XXCoder> but it is quite different when guy just want to do shit
[16:31:26] <zeeshan|2> theyre deaf not disabled
[16:31:31] <XXCoder> exactly
[16:31:41] <XXCoder> employers look at interpeter costs and say fuck no
[16:31:44] <zeeshan|2> that being said youre right
[16:31:48] <zeeshan|2> ive never worked with a deaf person before
[16:32:05] <XXCoder> well
[16:32:09] <zeeshan|2> so that basically just means a deaf person has to work twice as hard
[16:32:12] <zeeshan|2> to be more valuable
[16:32:15] <zeeshan|2> to justify the cost?
[16:32:16] <XXCoder> there is no "deaf person", just people who are deaf
[16:32:18] <zeeshan|2> thats not fair
[16:32:46] <XXCoder> not really its just a excuse in most cases
[16:32:54] <XXCoder> I can work without interpeter 99% of time
[16:33:01] <XXCoder> need interpeter if meeting
[16:33:05] <XXCoder> besides that nah
[16:33:46] <XXCoder> now that I am cnc operator I'm doing fine most times, and problems is due to my skills not my hearing ability
[16:34:03] <zeeshan|2> do you wear hearing protection?
[16:34:05] <zeeshan|2> sorry random q
[16:34:11] <XXCoder> most times no
[16:34:18] <zeeshan|2> :D
[16:34:22] <zeeshan|2> you get away with it!
[16:34:29] <zeeshan|2> you know here if they require hearing protection and youre cauight without it
[16:34:35] <zeeshan|2> the company can get fined 5000 or something silly like that
[16:34:39] <XXCoder> one time at old job theres vibrator I use plugs (not entire ear covers) because of bad dust that can damage ears
[16:34:41] <zeeshan|2> you can troll the inspectors
[16:34:43] <Deejay> gn8
[16:34:52] <zeeshan|2> ah
[16:35:04] <XXCoder> besides that never lol
[16:35:24] <XXCoder> anyway gonna go work, later :)
[16:36:55] <zeeshan|2> cya
[16:44:37] <CaptHindsight> will somebody please manufacture a small reliable and reasonably accurate mill
[16:45:02] <zeeshan|2> sure
[16:45:06] <zeeshan|2> 10k plz
[16:45:15] <CaptHindsight> do I gotta do everyting?
[16:47:40] <CaptHindsight> I could even use those Chinese mills if they came unassembled
[16:48:35] <CaptHindsight> if they could just machine everything consistently
[16:49:50] <MrSunshine> hmm, does the beaglebone green also have the pru's and will work with linuxcnc? =)
[16:49:55] <MrSunshine> cant find a pricetag etc
[16:54:19] <malcom2073> I'd imagine it does, since it uses the same design
[16:59:10] <MrSunshine> as it seems to promise to dump the price alot =)
[17:06:50] <just_pink> CaptHindsight: hass mini mill
[17:16:19] <zeeshan|2> lol @ mini mill costr
[17:16:20] <zeeshan|2> 45k
[17:17:32] <malcom2073> Indeed they are cheaper, nice
[17:19:10] <malcom2073> Lack of a hdmi port means x forwarding, or other remote control hacks though
[17:20:51] <zeeshan|2> ?!
[17:21:12] <malcom2073> linuxcnc on the beaglebone green
[17:23:29] <SpeedEvil> green?
[17:24:13] <si1v3r_> is new
[17:24:16] <PetefromTn_> CaptHindsight If only right LOL
[17:26:13] <Computer_barf> what machine are you running with the beaglebone malcom?
[17:27:18] <MrSunshine> malcom2073: found prices ?
[17:27:24] <malcom2073> MrSunshine: $39
[17:27:31] <malcom2073> Computer_barf: a 3d printer
[17:27:57] <MrSunshine> malcom2073: not bad .. thats like nothing =)
[17:27:58] <Computer_barf> cool
[17:28:10] <Computer_barf> i want to see someone run a mill with one
[17:28:21] <MrSunshine> ahh no display port at all ?
[17:28:23] <malcom2073> I thought about it, but tbh, it's not powerful enough to run axis
[17:28:42] <malcom2073> a full PC gives a much smoother user experience on a mill, something where you're interacting with the software more often
[17:29:19] <Computer_barf> perhaps you could use pins on the beaglebone for the interface
[17:29:29] <malcom2073> Possibly, like a pendant
[17:30:10] <Computer_barf> essentially build a pendant
[17:30:26] <Computer_barf> digital ins , buttons, etc.
[17:30:57] <malcom2073> Yeah it'd probably be doable, especially if you can get the reading of the I/O down far enough
[17:31:03] <Computer_barf> ive been thinking about building a small mill for certain operations on some parts
[17:31:05] <malcom2073> Keyboard input has *really* low priority
[17:31:21] <Computer_barf> like have the main mill doing the primary tasks and the small mill doing secondary tasks
[17:32:17] <Computer_barf> probably most of the time, put it in the fixture, press start
[17:32:23] <malcom2073> Small mill doing roughing, large mill doing precision, since roughing requires less precision... or would the precision be better for the small mill, since it's significantly less tool force?
[17:32:48] <Computer_barf> well i was just thinking engraving and champhering on the small mill
[17:32:51] <malcom2073> Computer_barf: It's the stuff like touching off and all that is crappy
[17:32:59] <malcom2073> If you've automated methods for that, you'd be set
[17:33:21] <malcom2073> Or tie jog commands into a hard I/O pendant
[17:33:53] <Computer_barf> hey whats the diffrence between setting z to zero on top of the material and touch off?
[17:34:01] <malcom2073> My first real user experience with linuxcnc was on the beaglebone, and it almost turned me off to it, until I tried it on a full size mill :-D
[17:34:20] <Computer_barf> since I face off the parts later I just lower z until it touches and set it to zero and start my program
[17:34:27] <andypugh> It’s been something like 16 months, but the shiny old lathe is now back together. And now the slides are tight and wobble-free.
[17:34:48] <andypugh> Computer_barf: It’s exactly the same thing
[17:35:19] <andypugh> How are you setting Z to zero if not using the “touch off’ button?
[17:35:38] <Computer_barf> move the z into place and hit home axis
[17:35:44] <andypugh> Ah.
[17:35:50] <andypugh> No home switches then?
[17:35:57] <malcom2073> Machine zero vs part zero
[17:35:57] <skunkworks> andypugh: was it you that uses autodesk fusion 360?
[17:36:04] <andypugh> That isn’t exactly the same thing then.
[17:36:15] <Computer_barf> should i be hitting touch off instead?
[17:36:25] <andypugh> skunkworks: No, I have full Autodesk Inventor Professional as a perk of work.
[17:36:31] <malcom2073> using touch off keeps soft limits effective I believe
[17:36:36] <malcom2073> keeps you from crashing the machine heh
[17:37:06] <andypugh> Computer_barf: If you don’t have home switches then it amounts to the same thing, but with your method you don’t get the protection of the soft limits
[17:37:23] <Computer_barf> lately ive been terrrified of doing anything new since what I am doing seems to be working, and whenever I change things my work day seems to be effectively canceled trying to figure things out lol
[17:37:42] <Computer_barf> if im cutting out hooks all day, i call it a big win.
[17:38:13] <andypugh> Better would be to home to fixed marks on the axes, then touch-off the XYZ. Then the machine will refuse to move outside the limits (if the marks are in the place that the INI says they are and the axis limits are right too.
[17:39:22] <Computer_barf> cool , good information going to notes to look at when i start the next batch after this plate
[17:39:57] <malcom2073> Yeah, my dads mill uses blue painters tape for home since he doesn't have home switches hooked up
[17:40:13] <malcom2073> if he forgets to return to zero before turning off, he zeros to that point to ensure gcode doesn't accidently crash
[17:40:16] <Computer_barf> i have the wires run
[17:40:21] <Computer_barf> lol , switches picked out
[17:40:29] <Computer_barf> parts designed for mounting them
[17:40:30] <andypugh> http://www.linuxcnc.org/docs/html/config/ini_homing.html
[17:41:19] <Computer_barf> i want to design a front chip guard to replace the one the mill came with
[17:41:44] <Computer_barf> mostly the reason on delaying installing the home switches
[17:43:20] <Computer_barf> the parts im doing now , i never even come close to the ends
[18:11:49] <PetefromTn_> Computer_barf what machine?
[18:12:06] <zeeshan-mill> so i cleaned the surfaces
[18:12:13] <zeeshan-mill> there was chips embedded in the surface
[18:12:20] <zeeshan-mill> someone definitely put the table on when it was dirty
[18:12:26] <zeeshan-mill> trying to remeasure now ;/
[18:12:44] <PetefromTn_> so now it should be PERFECT right hehe
[18:12:47] <zeeshan-mill> i hope so man
[18:12:50] <zeeshan-mill> im kinda excited
[18:12:55] <zeeshan-mill> i just gained 4" or room
[18:12:58] <zeeshan-mill> or 3"
[18:13:03] <zeeshan-mill> from spindle to table
[18:13:12] <zeeshan-mill> cause i moved the key to a diff slot on the vertical table
[18:13:20] <PetefromTn_> does that take into account the travel of the table/quill?
[18:13:27] <zeeshan-mill> its homing right now
[18:13:32] <zeeshan-mill> about to see if it will reach the table
[18:13:42] <zeeshan-mill> with quill closed
[18:13:46] <PetefromTn_> my machine does not even reach the table
[18:13:59] <Tom_itx> that's probably a good thing
[18:14:12] <PetefromTn_> hehe
[18:14:20] <zeeshan-mill> yay it reachs!!!!!!
[18:14:25] <PetefromTn_> it does pose a problem sometimes tho
[18:14:25] <zeeshan-mill> the tabl!!
[18:14:35] <zeeshan-mill> pete igot that prob in horizontal mode
[18:14:44] <Tom_itx> i run into that on my sherline once in a while
[18:15:00] <zeeshan-mill> moment of truth guys
[18:15:01] <zeeshan-mill> im so nervous
[18:15:05] <PetefromTn_> for instance I have had need to put something directly on the table before that is not thick and I can only reach it with extended length toolholders
[18:15:26] <zeeshan-mill> i guess you can always space it
[18:15:31] <zeeshan-mill> or build that index plate table
[18:15:44] <PetefromTn_> the machine has a bit more than 20" of Z so it is not really too big a deal...
[18:15:46] <zeeshan-mill> i think itd be nice to have more clearance
[18:15:52] <zeeshan-mill> 20 is a lot!
[18:15:53] <zeeshan-mill> lucky
[18:15:59] <zeeshan-mill> what about x a y
[18:16:01] <zeeshan-mill> *and
[18:16:18] <PetefromTn_> most of the time I put parts atop 123 blocks anyways so I don't risk cutting the table..
[18:16:26] <PetefromTn_> its 20x20x20
[18:17:10] <zeeshan-mill> nice!
[18:17:45] <zeeshan-mill> could you not stick your tool out more?
[18:17:51] <PetefromTn_> yeah wish it was 30x20x20 but I have not really ran into too many things I cannot do in a single pass
[18:18:16] <PetefromTn_> sure but that is not a great idea unless it is a drill or something
[18:18:28] <PetefromTn_> I have short and long length toolholders for that
[18:18:36] <PetefromTn_> still makes a difference
[18:19:48] <LatheBuilder> Hello. Been a while. While I've been gone I've sorted my VMC retrofit. Getting ready to cut parts today or maybe tomorrow. Have to retune the Z first.
[18:20:04] <PetefromTn_> SWEET!!
[18:20:08] <PetefromTn_> what kind of VMC?
[18:20:14] <LatheBuilder> Tell me about it, eh?
[18:20:47] <LatheBuilder> BT40 taper, 26 x 16 x 20 in travels.
[18:20:57] <zeeshan-mill> YAYYYYYYYYY
[18:21:05] <zeeshan-mill> there is improvement!!!
[18:21:16] <PetefromTn_> what brand machine is it?
[18:21:33] <LatheBuilder> been a long slog. Thanks for all the help here and in the archives.
[18:22:01] <just_pink> I'm looking for IR non contact temperature sensor
[18:22:17] <LatheBuilder> Taiwanese made. Used to have a dynapath control. Now Mesa 5i25/7i77. DC servos xyz, vfd spindle
[18:22:47] <LatheBuilder> just_pink - looking for handheld or industrial?
[18:22:59] <PetefromTn_> nice, DC servos? kinda unusual... I have the 5i25/7i77 and they are excellent
[18:23:02] <just_pink> someone know about not expensive sensor
[18:23:07] <LatheBuilder> Long Chang
[18:23:17] <PetefromTn_> HF sells one for cheap as I recall
[18:23:20] <zeeshan-mill> nice lathebuilder
[18:23:22] <just_pink> LatheBuilder: industrial - to monitor the bearings
[18:24:23] <LatheBuilder> >> just_pink check out the one from harbor freight. it is not too bad though if you are not local to a store you might like to get a better one. Mine took several returns to find a good one.
[18:24:46] <LatheBuilder> thanks zeeshan-mill & PetefromTn_
[18:25:18] <just_pink> I want just the sensore not not the "gun" type..
[18:25:23] <LatheBuilder> if I may, what do you guys use on your vmc's for acceleration limits?
[18:26:21] <LatheBuilder> just_pink what do need to use to capture the data?
[18:26:41] <JT-Shop> 10-20 times max velocity
[18:27:18] <just_pink> http://www.alibaba.com/product-detail/Wireless-infrared-temperature-sensor_312985295.html?spm=a2700.7724857.35.1.GDfHdl
[18:27:28] <just_pink> something like this thing..
[18:28:34] <LatheBuilder> I see where I am straying then. mine is set at 2in/s/s max rapid is 200 ipm thanks JT-Shop
[18:30:41] <LatheBuilder> just_pink what country are you in? for availability of local stock
[18:31:02] <just_pink> NY
[18:31:56] <LatheBuilder> for a professional installation, or a hobby project?
[18:33:01] <just_pink> to install in front of the bearings of the spindle
[18:33:49] <LatheBuilder> for your own use then. ok, in that case I would buy one of these:
[18:33:52] <LatheBuilder> http://www.harborfreight.com/infrared-thermometer-93984.html
[18:34:25] <LatheBuilder> and tear the housing down if it was too big to mount where I need it.
[18:36:16] <andypugh> If you are installiing permanently, why use IR? A contact thermocouple or thermistor will be a lot cheaper.
[18:37:02] <andypugh> You can wire them back into LinuxCNC and have temperatures displayed in an info tab.
[18:37:20] <andypugh> (I keep meaning to add my system voltages and coolant level to such a tab)
[18:39:24] <heyarn> hi folks, can anyone point me to where in the grbl firmware i would go to customize the geometry for my machine? I want to use the grbl shield with an Uno to drive a pan/tilt mechanism. :)
[18:41:00] <LatheBuilder> thermocouple will likely be more accurate as well.
[18:41:26] <cradek> heyarn: I don't think any grbl people are here
[18:41:36] <cradek> heyarn: linuxcnc and grbl are totally different
[18:42:09] <heyarn> ah i see sorry :) i couldn't find a grbl channel so i thought id ask here :)
[18:42:10] <Tom_itx> yeah you may as well check #reprap for that one
[18:42:25] <heyarn> yeah ill try them :)
[18:42:29] <heyarn> thanks folks! :)
[18:47:09] <andypugh> These little chips are nice for use with thermocouples (they link nicely to Arduino SPI) https://uk.rs-online.com/web/p/instrumentation-amplifiers/7861017/
[18:47:48] <andypugh> They do all the cold-junction and linearisation work, you get a number in degrees C out.
[18:48:56] <SpeedEvil> andypugh: TMP006 - TI - nice IR
[18:49:00] <SpeedEvil> in a chip
[18:49:05] <SpeedEvil> Same
[18:49:09] <SpeedEvil> (C out)
[18:49:59] <LatheBuilder> just_pink is it as a precaution for overtemp protection, or do you need narrow limit temps for spindle length control?
[18:57:44] <just_pink> LatheBuilder: just to know the temp..
[18:59:19] <just_pink> I'm going to connect it to the HMI
[19:04:33] <LatheBuilder> i'd lean away from ir and toward andypugh's suggestion then. The other down side to optical sensors is dirt contamination...no prob with thermocouple or thermistor
[19:06:17] <just_pink> LatheBuilder: - very good point!!
[19:07:32] <andypugh> You don’t need an actual thermocouple either. You can use thermocouple extension wire for the range you are looking at. Twist the ends together, trap them under a bolt, job done :-)
[19:08:15] <andypugh> There is no magic to thermocouples, just two wires in electrical contact at the point where you want to measure temperature.
[19:09:28] <just_pink> andypugh: I have about 20 of them...
[19:09:38] <andypugh> (The thermocouple effect takes place in each wire, not at the junction, every wire that is hotter at one end than the other has a different voltage at one end than the other. The point of a thermocouple is the two different wires havd two different different voltages, and you measure that difference)
[19:10:22] <just_pink> good reminder- i need to make tags for them..
[19:10:34] <andypugh> And now to sleep.
[19:10:36] <andypugh> Night all
[19:36:54] <PetefromTn_> http://diply.com/perfection/diy-black-light-camera-phone-easy-tape/164322 Pretty cool..
[20:19:26] <LatheBuilder> neat
[20:35:26] <PetefromTn_> Cool just sold a custom weaver rail that will be the FIRST anodized rail I have ever sold! Gonna start machining it tomorrow LOL
[20:42:48] <SpeedEvil> Woo!
[20:43:05] <just_pink_> ?
[20:49:07] <LatheBuilder> free float tube?
[20:50:31] <PetefromTn_> woo!!
[20:50:38] <PetefromTn_> ;)
[20:56:22] <just_pink> too much cutting oil in the food
[21:04:24] <PetefromTn_> Hey was that a crack LOL ;)
[21:05:57] <PetefromTn_> http://i.imgur.com/1rHrqtk.jpg One of these only brushed finish and black anodized...
[21:06:27] <os1r1s> PetefromTn_: Whats it for?
[21:07:03] <PetefromTn_> http://i.imgur.com/1Gda44T.jpg
[21:09:21] <os1r1s> PetefromTn_: Nice
[21:09:45] <PetefromTn_> thanks man I designed it to fit the rifle.
[21:17:36] <just_pink> PetefromTn_: WOW
[21:17:56] <just_pink> look so nice
[21:18:10] <just_pink> how did you make the finish?
[21:18:12] <jdh> would look good in Ti
[21:20:22] <just_pink> PetefromTn_: ^
[21:24:08] <PetefromTn_> sorry guys had to run out to the shop
[21:24:29] <PetefromTn_> just_pink Thanks I appreciate it. which finish are you talking about?
[21:24:55] <PetefromTn_> jdh I would make them in Ti if people wanted them but it would probably quadruple the cost LOL
[21:26:35] <just_pink> PetefromTn_: no tool marks
[21:27:12] <PetefromTn_> well of course I TRY to ensure that there are no tool marks but that is not always possible.
[21:27:59] <PetefromTn_> those two parts are two different finishes. The first one is a bead blasted finish that gives it a real matte look and of course removes any visible tool marks unless they are really bad.
[21:28:57] <just_pink> this is what I thought
[21:29:04] <PetefromTn_> the second one has a brushed finish I do this with both wet or dry sandpapers and scotch brite pads as well as scotch brite wheels. it is just a light brushed finish
[21:29:45] <PetefromTn_> honestly the parts come off the machine looking pretty damn good so neither of these is all that necessary it just gives it a more uniform appearance.
[21:30:06] <PetefromTn_> most shops that make aluminum parts like this typically use vibratory finishers or similar
[21:31:17] <PetefromTn_> http://i.imgur.com/8UYnzps.jpg here is a photo of one of them still on the machine after the first op.
[21:31:45] <just_pink> I thought to buy a tumbler but I'm wondering from the noise
[21:32:43] <just_pink> PetefromTn_: what rpm you using?
[21:33:12] <PetefromTn_> depends on the cutter and whatnot
[21:33:23] <PetefromTn_> my machine only runs max 6k RPM tho
[21:34:00] <os1r1s> PetefromTn_: How do you flip it and cut the other side
[21:34:04] <just_pink> I mean for this part
[21:34:05] <just_pink> LOL
[21:34:06] <just_pink> http://www.amazon.com/FNFAB-Tumbler-High-Capacity-Parts/dp/B007LVJLHE/ref=aag_m_pw_dp?ie=UTF8&m=A177E8613CXCNA
[21:34:10] <just_pink> OMG
[21:34:33] <PetefromTn_> LOL woah that is some rig hehe
[21:34:53] <just_pink> the wood cubes inside..
[21:35:26] <PetefromTn_> os1r1s well for that particular part It is a parallel part so the top is parallel with the bottom so I can just flip it over and clamp it in the vise jaws atop some parallels
[21:35:50] <PetefromTn_> then I can locate the Y halfway between top and bottom
[21:36:20] <PetefromTn_> and for that particular part I locate X even with the front vertical part of the leg of the rail
[21:37:00] <PetefromTn_> then it is just a matter of facemilling the flashing off, machining the pockets from the second side, and then champfering everything
[21:37:58] <PetefromTn_> I have actually seen a DIY for that kind of tumbler before somewhere
[21:38:29] <just_pink> PetefromTn_: you use hss or carbide?
[21:38:41] <PetefromTn_> both
[21:39:03] <just_pink> I have just hss end mills
[21:39:15] <redlegion> Nice piece, PetefromTn_
[21:39:27] <PetefromTn_> for that part I am using a carbide 3/8 to rough out the part followed by a HSS 1/4 inch 2 flute to finish the perimeter and an 1/8 three flute maritool cutter for the small pockets.
[21:39:38] <PetefromTn_> thanks redlegion
[21:40:50] <Tom_itx> you should get some insert cutters
[21:41:06] <Tom_itx> btw do you have any roughing cutters?
[21:41:13] <PetefromTn_> I have some but what specifically are you talking about?
[21:41:26] <PetefromTn_> I have quite a few roughers
[21:41:51] <Tom_itx> if you don't have a grind shop nearby you can use inserts
[21:41:55] <PetefromTn_> right now I would say I probably have a couple hundred different endmills
[21:42:28] <Tom_itx> probably can't find them much under 1" though
[21:42:51] <PetefromTn_> honestly most cutters are cheap enough that it is not really worth the trouble of sharpening them especially the sub 1/2 inch ones...
[21:43:27] <PetefromTn_> I get most of them from Maritool or Lakeshore Carbide and believe it or not some from Fastenal over here locally LOL
[21:44:10] <Tom_itx> http://www.shars.com/media/catalog/product/cache/1/small_image/233x/9df78eab33525d08d6e5fb8d27136e95/products/404-1863/404-1863Main.jpg
[21:44:33] <Tom_itx> i don't care for them in a way though since they're not centercutting
[21:44:34] <PetefromTn_> meh I have honestly NOT had that much luck with maritool
[21:44:46] <PetefromTn_> Err shars sorry
[21:44:52] <Tom_itx> just a pic
[21:44:57] <PetefromTn_> Maritool is excellent from my experience
[21:45:43] <Tom_itx> http://www.zoro.com/micro-100-indexable-end-mill-coolant-dia-1-14-in-30-4024/i/G7885771/?utm_source=google_shopping&utm_medium=cpc&utm_campaign=Google_Shopping_Feed&gclid=CjwKEAjw6IauBRCJ3KPXkNro1BoSJAAhXxpyg0DzcV13-2o2NodaAxHLkgrdxlf-PJzmvQ_oFOHrvxoCX_bw_wcB&gclsrc=aw.ds
[21:46:33] <just_pink> PetefromTn_: what's wrong shars?
[21:47:39] <PetefromTn_> well I have bought many things over the years from them and I would say half of them I was not happy with.
[21:48:07] <just_pink> Tom_itx: Cutting Dia.: 1-1/4" - it is almost face mill..
[21:48:10] <PetefromTn_> for instance I bought one of their coaxial indicators and it was out of round a good bit and wobbled on me
[21:48:30] <PetefromTn_> I fixed it in my old lathe so I can use it now but I should not have had to
[21:48:36] <Tom_itx> just_pink, depends on the mill :D
[21:48:44] <Tom_itx> we had some 6" shell mills
[21:48:46] <just_pink> G0704
[21:49:16] <PetefromTn_> I also bought one of their 6" CNC vises and it was kind of a POS not flat or square and the fixed jaw deflected pretty good when you crank down on it
[21:49:17] <cradek> my shars vise was just fine, after re-machining it flat and square
[21:49:32] <cradek> (it was pretty unusable the way it came)
[21:49:36] <PetefromTn_> +cradek LOL
[21:49:51] <cradek> I have also liked everything I've bought from maritool
[21:50:03] <cradek> maritool >> shars
[21:50:14] <PetefromTn_> I also bought one of those LED edge finders and it was not terrible but it would not pickup larger chunks of aluminum
[21:50:52] <just_pink> cradek: you are not supposed to machine your brand new vise to make them flat...
[21:50:58] <PetefromTn_> got a couple different mag bases with them and both of them the shaft came loose on the base and screwed up the threads
[21:51:23] <PetefromTn_> maritool sells some very good tools and holders for reasonable prices
[21:51:42] <Tom_itx> most of our holders were valenite
[21:52:08] <PetefromTn_> http://www.ebay.com/itm/New-1-INDEXABLE-END-MILL-EXTRA-LONG-INSERTS-/231543221210?pt=LH_DefaultDomain_0&hash=item35e90d2bda This type of insert mill I have found is pretty helpful to have
[21:52:23] <PetefromTn_> it has a wider cutting face than the shank diameter
[21:52:56] <PetefromTn_> this allows you to reach down and undercut things slightly OR allows you to make multiple depth passes without rubbing or having to grind the shank
[21:54:45] <just_pink> PetefromTn_: my G0704 feel so small now
[21:55:22] <PetefromTn_> just_pink LOL honestly while I think it is a decent machine it IS a very small mill
[21:56:18] <just_pink> :-S
[21:56:44] <PetefromTn_> sorry I have helped my pal connor here with his and seen it close up...
[21:57:36] <PetefromTn_> it is not bad for a very small mill tho. If you are used to any sort of commercial machine it will seem positively TINY
[21:58:57] <PetefromTn_> http://www.ebay.com/itm/SHARS-3-45-DEGREE-INDEXABLE-FACE-MILL-CUTTER-SEHT-SEHW-INSERTS-NEW-194-95-OFF-/300637690150?hash=item45ff671926 Much as I don't like shars I think this looks like a decent facemill and I have considered getting one to try
[21:59:45] <PetefromTn_> just_pink you mad bro? er miss? :D
[22:09:14] <PetefromTn_> https://www.youtube.com/watch?v=yLQoSp4JXKY OUCH!
[22:11:46] <Tom_itx> he probably won't remember it
[22:12:08] <PetefromTn_> heh probably not
[22:12:22] <PetefromTn_> I was working with my EX boss one time
[22:12:38] <PetefromTn_> back when I was a professional woodworker/Cabinet builder
[22:13:11] <PetefromTn_> they found this HUGE high powered vacuum system for a woodshop that was being sold at auction
[22:13:26] <PetefromTn_> it was down in South Alabama
[22:13:45] <PetefromTn_> they asked me to come with them and help them dismantle it so it could be shipped to our shop
[22:14:07] <PetefromTn_> so they rented one of those all terrain extenda boom lifts
[22:14:19] <PetefromTn_> and we brought an oxy ace torch
[22:14:32] <PetefromTn_> and grinders/cutoff wheels etc.
[22:14:43] <PetefromTn_> to cut this monster metal framework off the side of the building
[22:15:05] <PetefromTn_> I was hanging off the bucket cutting bolts and trying to get it done
[22:15:53] <PetefromTn_> my boss was standing behind me and he was like 58 years old or so at the time and he was getting impatient with me saying it was taking too long and that we would run out of gas before I cut the damn bolts/nuts off
[22:16:00] <PetefromTn_> so he kinda pissed me off
[22:16:17] <PetefromTn_> I turned off the torch and handed it to him and told him to do it himself
[22:16:37] <PetefromTn_> he steps in the spot I was standing in and fires up the torch
[22:16:47] <PetefromTn_> and starts cutting...not really any faster than I was
[22:16:58] <PetefromTn_> but he was in a mood so he was trying to prove something
[22:17:18] <Tom_itx> that seldom works out
[22:17:23] <PetefromTn_> next thing I know he is trying to jerk the cables which were really long
[22:17:47] <PetefromTn_> they ran down to the ground where the tanks were because I told them it was probably not the best idea to put them in the lift with us
[22:18:05] <PetefromTn_> he did not realize I tied the hoses to the railing of the kart box
[22:18:38] <PetefromTn_> so when he pulled up on it impatiently the handle kinda twisted when he ran out of hose and it turned the handle so that the fire went right by his right ear
[22:18:53] <PetefromTn_> basically disintegrated his ear lobe in about a half a second
[22:19:03] <SpeedEvil> Ow.
[22:19:09] <PetefromTn_> I felt really bad but it only happened because he was being an asshole
[22:19:19] <Tom_itx> karma
[22:19:21] <PetefromTn_> So I lowered us down and they took him to the hospital
[22:19:31] <PetefromTn_> just reminds me of this video somehow
[22:19:37] <SpeedEvil> Working with any tool when you're pissed is just a disaster.
[22:19:45] <PetefromTn_> torches are NOT to be played with LOL
[22:19:55] <PetefromTn_> aint it the truth.
[22:20:12] <PetefromTn_> I have hurt myself before getting stupid and impatient trying to push things
[22:20:34] <SpeedEvil> ^Got away damn lucky with it hitting him square in the head
[22:20:40] <SpeedEvil> - that is - on the mask
[22:21:16] <SpeedEvil> And that it diddn't have more spring
[22:21:33] <SpeedEvil> I question if he had adequate training
[22:23:07] <PetefromTn_> yup right in the grille... that had to smart pretty good. I am sure the mask probably protected his face from punctures but not from the sheer impact
[22:23:57] <SpeedEvil> And that it had already mostly stopped due to the spring
[22:24:47] <PetefromTn_> reminds me of a video I saw where a guy was branding a horse and walks up behind the horse right about when the horse lets loose that HUGE rear leg on him LOL
[22:25:17] <SpeedEvil> Horses can be gentle caring animals.
[22:25:32] <SpeedEvil> But they kill way more people than tigers
[22:26:37] <PetefromTn_> I have no use for an animal that can kill me with a kick, thanks but I will take a dirtbike or quardunner any day and I won't have to feed it or shovel up after it LOL
[22:28:26] <PetefromTn_> they are beautiful animals tho so I appreciate them from AFAR
[22:53:50] <mozmck> Reminds me of a rhyme I heard: "On mules we find, two legs behind, two legs we find before. We stand behind, before we find, what the two behind be for."
