[00:00:16] <XXCoder> unless they are aduts that own that place,
[00:00:24] <XXCoder> adults
[00:54:46] <mike_LCNC> hey guys
[00:55:14] <XXCoder> hey
[00:55:18] <XXCoder> bye
[01:25:46] <XXCoder> https://www.youtube.com/watch?v=wD8EbBS_KAI
[01:25:48] <XXCoder> not bad idea
[01:25:58] <XXCoder> when all you need is the weight
[02:34:15] <Deejay> moin
[03:33:16] <pink_vampire> XXCoder: i'm just lower my z axis..
[03:33:33] <XXCoder> whats wrong with it
[03:33:50] <pink_vampire> for clamping
[03:34:54] <pink_vampire> the servo push it vary hard. + the weight of the head..
[03:35:39] <XXCoder> im printing dial indictor holder for my 3d printer
[03:35:45] <XXCoder> so i have easy way to level.
[03:37:27] <pink_vampire> look, precision tools and plastic is not the way to go.
[03:38:45] <XXCoder> I just need it to precisely tell me distance from surface to any point on X assembly.
[03:40:10] <pink_vampire> for the cnc?
[03:40:26] <XXCoder> means I can make plate more or less exactly normal to X and Y
[03:40:48] <XXCoder> meaning layer is even. no slanting. well 3d printer is cnc too lol
[03:44:17] <XXCoder> hope I offset it correctly lol
[03:50:27] <pink_vampire> do you have a picture of it?
[03:50:39] <XXCoder> assembling it now
[03:54:52] <XXCoder> remember that its just short term addon
[03:54:57] <XXCoder> remove after leveling
[03:55:10] <XXCoder> uploading
[03:56:08] <XXCoder> http://picpaste.com/IMG_20161029_012438-SuZ5Y8RL.jpg
[03:59:32] <XXCoder> jeez
[03:59:35] <XXCoder> bed is way off.
[03:59:40] <XXCoder> .3 mm across bed
[04:01:05] <pink_vampire> i thing that you need to make sure that the bed can slide on one side, so it's not get bowed
[04:01:42] <XXCoder> it nmay be because its little too loose a second
[04:03:17] <pink_vampire> materials expend when heat it applied
[04:03:30] <pink_vampire> and also plastics
[04:03:47] <XXCoder> well of course. that is basic physics.
[04:04:05] <XXCoder> I thought I tuned it well but apparently not.
[04:04:35] <pink_vampire> so if you level it once, why you need to re-level it all the times?
[04:04:57] <XXCoder> because its reprap :)
[04:05:35] <pink_vampire> i'm level the head on the machine only after heavy cuts and most of the time is just perfect.
[04:06:35] <pink_vampire> i want to play my violin!
[04:24:04] <XXCoder> violin?
[04:24:11] <XXCoder> btw there is 3d printable one on thingverse LOL
[04:24:16] <XXCoder> no idea how good it is :P
[05:04:39] <XXCoder> hey jthornton
[05:19:36] <pink_vampire> i play on a violin few years ago.. then nails...
[05:19:46] <pink_vampire> XXCoder:
[05:19:55] <XXCoder> doh
[05:20:03] <XXCoder> some of hobbies cannot be combined.
[05:20:54] <pink_vampire> metal working, music (play and listen), nails..
[05:24:17] <XXCoder> cool'
[05:26:37] <jthornton> morning
[05:26:57] <XXCoder> I made and printed dial indictor holder
[05:27:13] <XXCoder> and found out my bed was pretty badly off lol
[05:27:52] <XXCoder> and in strange ways too. I had to remove glass, clean it, and finally remove tape and clean surface tii'
[05:28:09] <XXCoder> it was better but not whole lot better. .04 varance
[05:31:43] <pink_vampire> i'm not sure how to make the cable for the x axis
[05:36:05] <pink_vampire> i thing i need 2 drag chains
[05:36:10] <pink_vampire> think*
[05:43:13] <XXCoder> yeah?
[05:43:26] <XXCoder> why?
[05:49:32] <jthornton> made a dial indicator holder for the printer?
[05:53:29] <XXCoder> yeah
[05:53:38] <XXCoder> http://picpaste.com/IMG_20161029_012438-SuZ5Y8RL.jpg
[05:53:47] <XXCoder> it worked well enough lol
[05:54:12] <jthornton> ah cool
[05:54:40] <jthornton> did you just move around in XY directions and read the indicator?
[05:55:12] <XXCoder> yeah
[05:55:18] <XXCoder> it was strange
[05:55:26] <jthornton> why
[05:55:31] <XXCoder> so i cleaned it up and removed tape from alum bed
[05:55:40] <XXCoder> returned glass to it
[05:56:01] <XXCoder> it was more even but still not too flat (0.3mm vary)
[05:56:19] <XXCoder> it wasnt flat but not slanted, just weird
[05:57:11] <jthornton> the glass was wavy?
[05:57:33] <XXCoder> it is. but problem was under glass was not clean alum lol
[05:57:51] <XXCoder> and overall there was small slant too. fixed that too. printed nice
[05:58:25] <jthornton> cool I need to get my X axis mounted and test out the E3D hot end
[05:59:11] <jthornton> and put my LM8LUU bearings in the Z axis to replace the LM8UU bearings
[05:59:13] <XXCoder> nice. :)
[06:00:22] <jthornton> but I have to go back to the wood place today and finish up a PLC swap out on the dip tank
[06:00:39] <pink_vampire> the x axis is seat on the y axis..
[06:00:43] <jthornton> got stuck yesterday on a allen bradley nema type starter
[06:01:04] <jthornton> start stop circuit lol
[06:01:56] <pink_vampire> so the extra cable that drag after the x axis is count, but also extra cable count because of the y axis travel
[06:01:58] <pink_vampire> XXCoder:
[06:02:06] <XXCoder> yeah
[06:02:13] <XXCoder> my cnc router has 2 drag chains
[06:02:40] <pink_vampire> one sec i'm taking picture
[06:06:30] <pink_vampire> i can't find an angel that show the problem
[06:08:36] <XXCoder> oh well
[06:15:58] <pink_vampire> http://i.imgur.com/yfyH1RQ.png
[06:16:41] <XXCoder> hmm
[06:16:43] <pink_vampire> this is the problem that i have with the cable on the x axis
[06:17:19] <XXCoder> probably does need 2 drag cables
[06:17:29] <XXCoder> thats how my cnc router does it.
[06:17:52] <pink_vampire> but how do i connect them to the machine
[06:18:06] <XXCoder> Y only needs one drag cable but Z needs 2, because wires need to be routed there
[06:18:26] <XXCoder> in my machine Y and Z share same drag chain
[06:18:44] <XXCoder> then Z goes into its own drag chain on way to motor so as Y moves it does not snag
[06:18:55] <pink_vampire> and how i protect the cable from razor sharp chips in the drag cable?
[06:19:29] <XXCoder> that part im not too sure too
[06:20:30] <pink_vampire> how large companies solve it?
[06:20:57] <XXCoder> big machines I use at work use completely covered drag chains
[06:22:18] <pink_vampire> steel
[06:22:19] <pink_vampire> ?
[06:22:30] <XXCoder> nah plastic
[06:22:51] <XXCoder> most machines are mostly enclosed anyway
[06:26:04] <pink_vampire> http://www.hubbell-gleason.com/engprod/PowerTrak/Catalogs/PwrFlex.pdf
[06:36:21] <jthornton> have two cable chains one on each axis
[06:36:46] <XXCoder> yeah thats what my machine has
[06:44:41] <jthornton> mine just has flex that dangles to the box
[06:45:45] <pink_vampire> i need to make mount for the stepper motor driver
[06:45:58] <pink_vampire> that can goon the din rail
[06:46:17] <sync> pink_vampire: by using proper drag chain cable that is hard to cut
[06:46:52] <pink_vampire> sync:proper drag chain cable = ?
[06:47:48] <XXCoder> https://www.amazon.com/Machine-7-3mm-Cable-Carrier-Nested/dp/B008SKT00A
[06:47:49] <pink_vampire> any idea for good brand?
[06:47:55] <XXCoder> similiar to one I used
[06:48:35] <pink_vampire> but you are cutting wood.. on metal the chips came hot and sharp
[06:49:16] <XXCoder> yah. those can take the abuse. though I dont know about hole sections so metal would be able to get in.
[06:49:38] <XXCoder> big machines I run has similiar, but has more parts to cover any gaps. and much bigger of course.
[06:50:42] <pink_vampire> http://i.imgur.com/wZRrDzS.png
[06:51:05] <XXCoder> heh small pile of chips
[06:52:08] <sync> pink_vampire: igus chainflex
[06:53:10] <XXCoder> ironically last thursday I made less chips than that in 10 hours. 4 different operations I ran that day was all just hole making or prep grip setups
[06:53:18] <XXCoder> none making much chips.
[06:54:29] <pink_vampire> sync: i see just cables
[06:56:53] <XXCoder> I found this mic. https://www.thingiverse.com/thing:1257186
[06:57:08] <XXCoder> how precise and repeatable is it, what you guys think heh
[06:57:10] <pink_vampire> http://www.igus.com/wpck/17554/overview_E2micro
[06:57:15] <pink_vampire> sooooooooooooo cuuuuuteeeee
[06:57:25] <pink_vampire> i want them in pink!
[06:57:46] <XXCoder> there is 3d print models you can print up and make heh
[06:58:15] <XXCoder> https://www.thingiverse.com/search?q=drag+chain&sa=
[07:00:06] <pink_vampire> i don't have good adhesion in the printed parts
[07:00:27] <XXCoder> you mean staying on surface as its being printed?
[07:00:32] <XXCoder> or inter-layer fusion?
[07:02:18] <pink_vampire> the end of youtube https://www.youtube.com/watch?v=d9TpRfDdyU0&feature=
[07:02:28] <XXCoder> looking
[07:04:31] <jthornton> https://www.youtube.com/watch?v=ptmxSjxWM70
[07:05:45] <XXCoder> I looked even though i thought it would be another music videp
[07:06:22] <pink_vampire> something wrong happening to the world https://en.wikipedia.org/wiki/PPAP_%28Pen-Pineapple-Apple-Pen%29
[07:09:13] <XXCoder> jthornton: nice
[07:09:34] <jthornton> yea seemed like a neat way to indicate a non round part
[07:45:46] <enleth> pcw_mesa: are there any guidelines regarding shared ground and avoiding ground loops between a 7i77, the host PC, the field I/O and stuff connected to those?
[08:10:28] <Meduza> XXCoder: about that 3d printable Violin, i am acutally printing the last parts for one of those right now :p
[08:10:39] <Meduza> the http://www.hovalin.com/
[08:11:28] <Meduza> tough mine is fancier than most, since i use Colorfabb Corkfill for the body and Colorfabb XT-CF20 for the neck :-)
[08:20:57] <Frank_20> hii
[08:26:49] <MacGalempsy> mornin
[08:43:23] <jthornton> morning
[08:45:33] <MacGalempsy> hi jthornton hows the printer going#
[08:59:22] <Tom_L> morning
[09:02:25] <MacGalempsy> hi
[09:02:36] <JT-Shop> doing pretty good about to get all the undocumented features sorted out
[09:03:27] <MacGalempsy> undocumented features?
[09:03:58] <Tom_L> they come with no extra charge
[09:04:09] <JT-Shop> lol
[09:04:25] <JT-Shop> things you need to fix to make it print better
[09:05:06] <MacGalempsy> lol
[09:05:25] <MacGalempsy> like replacement parts?
[09:05:38] <archivist> or all of it
[09:05:45] <MacGalempsy> lol
[09:06:22] <JT-Shop> no, just minor things like getting rid of slop in rods with tape shim stock
[09:06:24] * MacGalempsy welcomes everyone one to #thegluegunchannel
[09:06:47] <JT-Shop> the biggest thing was adding some print fans for $8
[09:07:40] <MacGalempsy> ah. yesterday i added kapton tape to the bed glass. prints stick WAY BETTER
[09:07:45] <Tom_L> those robo ones at the uni have 2 40mm ones near the head
[09:08:12] <JT-Shop> I added a glass to mine and just use white rain hair spray
[09:08:15] <Tom_L> one on the print at an angle and the other on the extruder above the heater
[09:09:00] <JT-Shop> yea you have to keep the cold side of the hot end cool
[09:09:03] <MacGalempsy> i used hairspray and this is handsdown the best adhesion ive ever had
[09:09:29] * JT-Shop heads off to the lumber place to finish (I hope) fixing the dip tank controls
[09:09:34] <Tom_L> you should go all out and make a water cooler for it
[09:10:03] <MacGalempsy> yea with cpu cooling blocks
[09:10:05] <JT-Shop> don't need that the fan does fine
[09:10:15] <JT-Shop> see you guys later
[09:10:19] <MacGalempsy> bye
[09:10:21] <Tom_L> they need a better thermal barrier between the heater and the top of the extruder
[09:10:43] <MacGalempsy> i use the budaschnozzle
[09:10:48] <JT-Shop> Tom_L: I did make some more progress on the logger this morning, log indexes are in descending order now
[09:10:57] <MacGalempsy> it has a ptfe block
[09:11:00] <JT-Shop> just need to change the append to insert
[09:11:19] <JT-Shop> I have the all metal E3D
[09:11:52] <Tom_L> nice
[09:12:17] <Tom_L> will it resort an exhisting directory?
[09:59:25] <R2E4> anyone up?
[10:13:06] <MacGalempsy> nope
[10:14:26] <MacGalempsy> a friend of mine hooked me up a ball mill
[10:14:58] <archivist> a power station coal pulverising ball mill?
[10:15:14] <archivist> they are not small :)
[10:15:26] <MacGalempsy> rocl tumbler :)
[10:15:29] <MacGalempsy> rock
[10:16:30] <archivist> I went on a few power station open days, quite interesting
[10:20:46] <MacGalempsy> big motors
[10:20:57] <MacGalempsy> capacitors
[10:21:10] <MacGalempsy> what else?
[10:21:12] <archivist> big boilers
[10:21:39] <archivist> 500MW turbines are not small
[10:22:01] <gregcnc> capthindsight did you find any interesting 100W-200W servos? Some of the yaskawa are very small. trying to plan a retro to the emco mill
[10:22:24] <archivist> one power station might still be using gears made by me :)
[10:24:07] <archivist> they wanted another 10 years out of their chart recorders http://www.collection.archivist.info/searchv13.php?searchstr=gears+rugeley
[10:26:01] <archivist> poor thing it shut this year in June
[10:26:17] <CaptHindsight> gregcnc: found a bunch of yaskawa 50-100w ~17's/40mm and ~200w 23's and matching drives
[10:26:27] <gregcnc> ebay or?
[10:27:00] <CaptHindsight> gregcnc: yeah ebay, once you have some good series numbers it gets easier to find them there
[10:27:31] <gregcnc> right, most of the cheap one seem to be pushing 15 years old
[10:27:33] <CaptHindsight> I got a great deal on a 100w "yascawa" obviously due to the typo :)
[10:27:44] <gregcnc> hah
[10:28:12] <CaptHindsight> motor and drive for ~$150 shipped
[10:28:23] <gregcnc> that's a good deal
[10:28:33] <gregcnc> 13 bit encoder?
[10:28:59] <CaptHindsight> there are a bunch of 100w delta AC servo drives new in box for ~$70
[10:29:07] <gregcnc> is serial encoder a non issue?
[10:29:26] <CaptHindsight> 2048/rev incremental
[10:30:03] <CaptHindsight> gregcnc: download all the docs from Yaskawa, they are a bit confusing
[10:30:13] <gregcnc> i'm going through them now
[10:30:31] <CaptHindsight> motor and drive part numbers are listed in the middle of 300 page docs
[10:31:01] <CaptHindsight> the main thing to watch for is Speed vs Position control drives
[10:31:21] <gregcnc> ok
[10:31:29] <CaptHindsight> I'm using it with a 40tpi screw and 1um glass encoder
[10:31:45] <gregcnc> ok that was next question, so separate axis encoder
[10:32:23] <CaptHindsight> my app has to be dead on
[10:33:24] <gregcnc> the little emco makes great parts and finishes, except when the steppers resonate, which is always on a circle
[10:34:12] <CaptHindsight> there is a setting for the encoder divider so the drives can work with any quad encoder
[10:34:29] <Roguish> gregcnc: hey, which emco do you have?
[10:34:37] <gregcnc> my frankenmill was with gecko servo so I was spoiled in that department
[10:34:40] <gregcnc> PC Mill 125
[10:36:07] <gregcnc> I found a curious "feature" it monitors spindle load while cutting and does a brief feed hold if it loads up and RPM drop.
[10:36:26] <gregcnc> so if you push the limit on power you get a bunch of short moves
[10:37:50] <gregcnc> the servos are in the enclosure and while I run mist for now, the servos really should be rated for flood
[10:38:19] <gregcnc> actually only X is in the flood plain
[10:50:06] <MacGalempsy_> this is sweet https://youtu.be/tW0PxUzTRT8
[10:50:26] <MacGalempsy_> that chain between the clamp slide is interesting
[10:52:15] <CaptHindsight> gregcnc: there are lots of size 23 parker servos on ebay and older gemini drives
[10:56:25] <CaptHindsight> gregcnc: http://www.ebay.com/itm/311726889415 4 mitsubishi $150
[10:57:59] <CaptHindsight> http://www.ebay.com/itm/191990514271 $80 for servo and positioner!
[10:58:09] <CaptHindsight> with cables
[10:59:51] <CaptHindsight> http://www.ebay.com/itm/NEW-Delta-ASD-B0121-A-AC-Servo-Drive-100W-SEE-DESCRIPTION/161904687116 $60 NEW no box 100w AC drive
[11:07:27] <CaptHindsight> gregcnc: new in box $164 http://www.ebay.com/itm/Yaskawa-AC-Servo-Motor-SGM-01B314-/331976181723
[11:12:16] <gregcnc> I still have to do the math on the servos. Original is a 2Nm 3 phase stepper run at what seems to be 1000 step/rev
[11:12:47] <gregcnc> haven't decided if 100W or 200W
[11:14:37] <CaptHindsight> http://www.convertunits.com/from/N-m/to/oz-in
[11:16:38] <gregcnc> if i reduce stepper torque to account for microstepping, the axis thrust is 37% of machine spec
[11:17:32] <gregcnc> so i'm a bit confused about how it was rated
[11:18:33] <archivist> steppers are often quoted full step at a very low speed as it drops off a lot with speed
[11:18:59] <CaptHindsight> gregcnc: what is the screw pitch?
[11:19:46] <gregcnc> steppers yes, but i've calculated for other emco and the numbers worked out with micro step torque reduction
[11:20:52] <gregcnc> 2:1 belt, 5mm pitch, 2kN thrust rated
[11:21:07] <gregcnc> i have a spreadsheet setup to figure this
[11:22:06] <CaptHindsight> the 200w yaskawas are 0.637Nm
[11:22:22] <CaptHindsight> peak is 1.91Nm
[11:23:35] <gregcnc> that should be adequate, I need to look into how peak loads are figured into machine operation
[11:24:40] <CaptHindsight> ballscrew?
[11:24:45] <gregcnc> yes
[11:24:49] <CaptHindsight> yeah
[11:25:50] <CaptHindsight> my top speed is ~100um/min
[11:26:04] <gregcnc> going nowhere fast
[11:26:32] <CaptHindsight> slow moving Z-axis, fast XY galvos
[11:26:57] <gregcnc> that still for the sla?
[11:27:16] <CaptHindsight> SLS
[11:27:40] <gregcnc> we went to CL library fall fun last weekend a few guys were running a pair of 3d printers
[11:27:41] <CaptHindsight> laser + powder
[11:29:24] <gregcnc> the had a kinect scanning people by rotating on a stool
[11:31:48] <CaptHindsight> I'm off to fab a bunch of curved sheet metal, fun fun
[11:32:13] <gregcnc> later
[11:34:11] <archivist> wheeling machine or hammer and anvil
[11:43:31] <CaptHindsight> yes and lots of cursing
[11:44:11] <CaptHindsight> excellent example http://www.monocoque-metalworks.com/main/2013/11/ge-rear-wheel-arch/
[11:57:08] <archivist> CaptHindsight, actual Jag work? /me has serial numbers from the factory, engine rectification records
[11:59:56] <CaptHindsight> archivist: different make, same project
[12:00:16] <CaptHindsight> archivist: are those E-series as popular there as they are here?
[12:00:31] <archivist> silly prices over here
[12:00:37] <CaptHindsight> ok, the same
[12:22:53] <Meduza> If i want to control more than 5 axes of motion with a Mesa ethernet card, wich would i use (or combination of card and daughter card)?
[12:37:50] <zeeshan> anyone here use hsm
[12:41:51] <Kevin`> the general toolpath techniques or some specific product?
[12:42:07] <zeeshan> inventor hsm
[12:42:07] <zeeshan> sorry
[12:42:28] <Kevin`> heh yeah, thought so. kind of an odd question otherwise
[12:43:05] <zeeshan> hehe
[12:43:14] <zeeshan> having a hard time doing multiple setups on it
[12:43:18] <zeeshan> not sure why its being a pain!
[12:52:38] <gregcnc> autoparts for AN fittings locally?
[12:52:50] <zeeshan> not going to happen
[12:52:53] <zeeshan> bust out the lathe!
[12:53:03] <zeeshan> are they sae45 deg or jic 37
[12:53:55] <gregcnc> one is 37 , marked AN, the other not sure, looks 37 but is opposite gender and the thread doesn't match the damn an chart
[12:54:26] <zeeshan> they're mating together?
[12:54:33] <gregcnc> i'm adding an after cooler to my california compressor
[12:54:34] <zeeshan> do you have a hydraulic store locally?
[12:54:44] <zeeshan> up here we have a place called princess auto
[12:54:47] <zeeshan> its like harbor freight
[12:54:55] <zeeshan> harbor freight will likely have
[12:55:05] <gregcnc> HF website doesn't show any
[12:55:48] <zeeshan> im sure you have a hydraulic store open
[12:55:55] <zeeshan> but it is past 1
[12:56:00] <zeeshan> locally mine are closed =/
[12:56:01] <gregcnc> this can wait
[12:56:07] <gregcnc> i'll have to check
[12:56:11] <zeeshan> then hydraulic store for sure
[12:56:12] <zeeshan> they have
[12:56:16] <zeeshan> is it npt on one side
[12:56:18] <zeeshan> and an on the other
[12:56:29] <CaptHindsight> gregcnc: what size? Found a few at Farm & Fleet, Menards has a small selection
[12:57:08] <gregcnc> i didn't looka t menards site
[12:57:10] <zeeshan> fuck im really having a hard time w/ changing part orientation
[12:57:18] <zeeshan> to machine another side of a part
[12:57:23] <zeeshan> im not sure why inv hsm is failing me
[12:57:25] <CaptHindsight> gregcnc: not open till Monday http://www.midhose.com/
[12:57:33] <CaptHindsight> ^^ Johnsburg
[12:58:23] <gregcnc> zee yeah that's not intuitive easiest way to be sure is add a coordinate system in the model
[12:58:47] <gregcnc> thanks Capt, if nothing I'll check with them monday
[12:59:33] <zeeshan> gregcnc: you use it right?
[12:59:36] <CaptHindsight> gregcnc: Lee on rt14 also carries a few
[12:59:46] <gregcnc> I use hsmxpress in SW
[12:59:56] <zeeshan> apparently hsmxp can deal with it
[13:00:02] <zeeshan> but not inv hsm
[13:00:14] <gregcnc> how did that happen?
[13:00:15] <zeeshan> like its such a common thing to want to do this..
[13:00:31] <gregcnc> I set up two job on a single part all the time
[13:01:10] <zeeshan> lemme show you a pic of where im stucjk
[13:01:17] <zeeshan> this is a random part i drew up
[13:04:16] <zeeshan> http://i.imgur.com/tPetBoC.png
[13:04:19] <zeeshan> that is op 1
[13:04:30] <zeeshan> i mean machining side 1
[13:04:33] <zeeshan> http://i.imgur.com/YLWr1Mn.png
[13:04:36] <zeeshan> this is machining side 2
[13:04:44] <zeeshan> notice how it tries to cut the curved section again?
[13:04:49] <zeeshan> w/ adaptive
[13:05:19] <gregcnc> i need to get into the pocket toy/junk biz that tactical keychain guy just bought a speedio and hadn't run his robodrill in like 3 weeks machine utilization is lower than low
[13:05:49] <gregcnc> you can define stock boundaries
[13:05:54] <gregcnc> with a sketch
[13:06:00] <zeeshan> OH
[13:06:06] <zeeshan> let me try that
[13:07:29] <Tom_L> duh
[13:07:31] <Tom_L> :D
[13:07:58] <zeeshan> i tried this before
[13:08:03] <zeeshan> i remember now
[13:08:08] <Tom_L> in catia you define your stock as a part as well
[13:08:10] <zeeshan> it tries to keep the tool within the model geometry
[13:08:32] <Tom_L> then 'assemble' them together
[13:08:40] <Tom_L> with an anchor point
[13:08:48] <zeeshan> never mind
[13:08:48] <zeeshan> it worked
[13:08:50] <zeeshan> youre right
[13:08:52] <zeeshan> im stupid :)
[13:09:03] <Tom_L> when you flip the part you need to disable the anchor temporarily
[13:09:34] <Tom_L> and move the whole assembly to the new position
[13:11:43] <zeeshan> nm
[13:11:46] <zeeshan> it still crashes
[13:12:05] <zeeshan> but i can see that it can be fixed using a manual sketch
[13:13:01] <nubcake> hi
[13:13:05] <gregcnc> just need to be smarter than the software
[13:13:15] <zeeshan> are you calling me dumb
[13:13:38] <zeeshan> want i will beat you with my high speed chips
[13:13:38] <zeeshan> !
[13:13:43] <zeeshan> want = cause
[13:17:38] <gregcnc> no, just learning how to take advantage of what they offer
[13:17:49] <gregcnc> even if they don't say so
[13:17:51] <zeeshan> honestly dude
[13:17:59] <zeeshan> i click so much less in inv hsm now
[13:18:02] <zeeshan> in comparison to mastercam
[13:18:05] <zeeshan> it feels like im making mistakes
[13:18:06] <zeeshan> lol
[13:18:15] <zeeshan> (like forgetting something to do)
[13:20:03] <gregcnc> https://www.instagram.com/p/BMJgGOjlUL0/ 2" face mill on 1/2 shank for router
[13:20:45] <zeeshan> lol
[13:20:52] <zeeshan> looks like a straight shank too
[13:21:02] <zeeshan> that'll do REAL well!
[13:21:16] <gregcnc> for wood
[13:21:20] <zeeshan> O
[13:21:22] * Loetmichel_ s wife just made a pot of "einstein-heisenberg" soup (thats a pun about "relativ unscharf" in german)... Ground meat as for bolognese, some fresh mushrooms, two cans of coconut milk, and a complete can of green thai curry... *cough* ... * tears in the eyes* she should work a bit on the heisenberg part ;)
[13:22:11] <zeeshan> gregcnc: is that you
[13:22:12] <gregcnc> still I'd be terrified
[13:22:14] <gregcnc> no
[13:22:23] <zeeshan> good
[13:22:31] <zeeshan> we dont need to lose you from a face mill into your face!
[13:23:06] <Jymmm> Loetmichel_: Well, is your face fuzzy or not?! lol
[13:23:11] <zeeshan> jeez you have a lot of 5c collets
[13:23:38] <Loetmichel_> Jymmm: it feels a bit fuzzy right noe ;)
[13:23:45] <Loetmichel_> now
[13:23:50] <Jymmm> Loetmichel_: haha
[13:23:50] <gregcnc> cheap ebay lots. I got like 50 emergency that were barely used for $150 maybe
[13:24:32] <Loetmichel_> Jymmm: more precise it feels a bit numb at the moment ;)
[13:24:58] <Jymmm> gregcnc: Nah, that is no big deal, now THIS on the other hand are scary as fuck to use... http://www.icscuttingtools.com/imagesMX/products/sing-blde-univ-hole-ctr.jpg
[13:25:29] <Jymmm> gregcnc: Yes, I have one and have used it. All I can say is damn....
[13:25:32] <gregcnc> yeah i have one of those, I hate using it
[13:25:50] <Loetmichel_> Jymmm: i see you and raise to: http://www.cyrom.org/palbum/main.php?g2_itemId=5474
[13:25:55] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=5471

[13:26:21] <Loetmichel_> 80mm sawblade on a 6mm shaft... hold on by a 0,5mm taper on the end of the shaft... ;)
[13:29:45] <Jymmm> Loetmichel_: Your s beats this, but only b a slight margin http://www.harborfreight.com/4-in-mighty-mite-table-saw-with-blade-61608.html
[13:29:51] <Jymmm> by*
[13:30:41] <Loetmichel_> have i mentoined that that blade spins at 20kRPM?
[13:30:42] <Jymmm> Loetmichel_: That lil fucker is scary as fuck, no stability to it's base, uses a 1/16" blade, so even no teeth it can still rip ya to shreds =)
[13:30:45] <Loetmichel_> :-)
[13:31:23] <Jymmm> Loetmichel_: Well, I think that would be instant death and dismemberent.
[13:31:24] <gregcnc> 20kRPM? why
[13:31:48] <Loetmichel_> I admit to have positioned myself behind the gantry side post when first operating it... ;)
[13:32:02] <Jymmm> Loetmichel_: ya thaink?!
[13:32:05] <Loetmichel_> gregcnc: habit. the pot on the VFD was always rightmost ;)
[13:32:07] <Jymmm> think*
[13:32:53] <gregcnc> if my boss needed some shit like that done i'd tell him to job it out
[13:33:07] * Jymmm forcenickchange Loetmichel_ TimTheToolmanTaylorUGUGUGMorePower
[13:33:17] <Loetmichel_> hihi
[13:33:49] <Loetmichel_> i just needed a slitting saw which could cut down to the surface
[13:34:12] <Loetmichel_> and i saw the slightly damaged circular sawblade laying around...
[13:34:34] <Loetmichel_> took a M10 Bolt into the lathe...
[13:34:48] <Loetmichel_> a few minutes later the contraption was ready to use ;)
[13:34:52] <Jymmm> Loetmichel_: They call them TABLE SAWS with guides attached
[13:35:19] <Jymmm> ...and include height adjustments and NOT 20K rpm
[13:36:12] <Loetmichel_> Jymmm: to your dismemberment argument: i dont think so
[13:36:30] <Loetmichel_> the sawblade simply hasnt enough mass to do more than a few nasty cuts
[13:36:37] <Loetmichel_> even at 20krpm
[13:36:46] <Loetmichel_> not enough stored engergy
[13:37:03] <Loetmichel_> but i would wear some protective glasses... just in case ;9
[13:37:03] * Jymmm waits for the photo of Loetmichel_9_fingers
[13:37:09] <gregcnc> 9 fingers is enough?
[13:37:13] <gregcnc> lol
[13:37:22] * Jymmm high fives gregcnc
[13:37:27] <Loetmichel_> i still have all 10
[13:37:32] <Loetmichel_> ... surprisingly ;)
[13:38:22] * Jymmm ponders if Loetmichel_ looks down the barrel to see if it's loaded, or uses a match to check for gas leaks
[13:38:56] <Loetmichel_> not the first one because we have strict gun laws here
[13:39:07] <Loetmichel_> ... but did the second. quite often
[13:39:20] <Loetmichel_> after repairing some gas pipes
[13:39:27] * Jymmm just shakes his head
[13:39:52] <Loetmichel_> easiest way to find some leaks... open the main valve and run the lenght of the pipe with a cigarette lighter
[13:40:17] <Loetmichel_> if you have a leak (that you cant HEAR) you will have a tiny flame on the leaking spot ;)
[13:40:35] <sync> you can also just use the dtek
[13:40:37] <Jymmm> I prefer the bubbles, they are more fun anyway
[13:40:56] <Loetmichel_> if yxou can HEAR the leak when opening the main valve i recomment to NOT light a cigarrette tho
[13:41:02] <Loetmichel_> have seen how that goes...
[13:41:20] <Loetmichel_> a friend of mine is "gas wasser scheisse" master of trade...
[13:41:33] <CaptHindsight> I'm too lazy for either method. I just go to sleep and I wake up, No Leak, simple
[13:41:34] <Loetmichel_> his apprentice installed a furnace...
[13:41:56] <Loetmichel_> in a newbuilt building cellar
[13:42:14] <Loetmichel_> then came up to my friend: "it wont start, can you look at it?"
[13:43:01] <gregcnc> Capt I went to Able in Mhenry to buy a gas valve. they did sell me one without question years ago, he just said "there won't be any problems"
[13:43:04] <Loetmichel_> so my friend got down and checked... All valves open... no ignition... "no idea whats causing that, lets have a cigarrete and think about it"
[13:43:11] <Loetmichel_> ... *FFFUMP*
[13:43:35] <Loetmichel_> He said he could see about 1 foot light when the house briefly lifted off the cellar
[13:43:40] <Jymmm> Loetmichel_: So, he found the probelm =)
[13:44:36] <Loetmichel_> Jymmm: yeah. Faulty ingiter AND faulty safety valve...
[13:44:49] <Jymmm> Loetmichel_: nice
[13:45:10] <Jymmm> Loetmichel_: and NOBODY smeeled the gas?
[13:45:14] <Loetmichel_> Vaillant even paid for rebuilding the house to keep that double fault under the carpet ;)
[13:45:28] <Loetmichel_> Jymmm: obviously not
[13:45:41] <Jymmm> Loetmichel_: the mfg did?
[13:45:55] <Loetmichel_> vaillant was the mfg ;)
[13:46:00] <Jymmm> k
[13:47:16] <Jymmm> Does anyone know anything about Radiant Heat Transfer Plates ?'
[13:47:47] <Loetmichel_> and apparently german "citygas" is so heavy that it just settles to the lowest point if not disturbed much
[13:48:12] <Loetmichel_> so it cant be smelled easily (if not disturbed)
[13:48:36] <Jymmm> Loetmichel_: That sounds like propane her,e but that shit stinks and hard NOT to smell it, but I get it.
[13:48:54] <CaptHindsight> everyone knows that us Germans are gas experts :)
[13:49:07] <Loetmichel_> CaptHindsight: that was some time ago ;)
[13:49:09] <CaptHindsight> sorry too soon
[13:49:40] <Loetmichel_> Jymmm: actually not
[13:51:31] <Jymmm> not what?
[13:51:51] <Loetmichel_> its simply "erdgas H" (natural gas) so mostly methane
[13:52:05] <Loetmichel_> and they even add some smelly component to it
[13:52:35] <Jymmm> Loetmichel_: Yeah, that's what I meant. It's artificial smell, but it's very pungent
[13:53:20] <Loetmichel_> its distributed by pipes
[13:53:40] <Loetmichel_> as opposed to some places that have big propane tanks in the backyard
[13:54:20] <Jymmm> Loetmichel_: Both NG (natural gas) and LPG (propane) have the injected smells
[13:54:54] <Loetmichel_> which (to me) is a lot more terrifying... to think one has a steel container in the backyard that has about 2000kg liquified propane in it...
[13:55:47] <Loetmichel_> i mean in comparsion to a low pressure gas line coming into the house
[13:55:49] <Jymmm> Loetmichel_: I do, and it's not THAT bad
[13:57:32] <Loetmichel_> i have accidentally thrown a full cartridge of "camping gaz" ( 190 gr of propane/butane IIRC) into a campfire
[13:57:43] <Loetmichel_> pretty "flasbang" kind of effect.
[13:57:50] <Jymmm> I think I'm more terrified of my nitrogen tank faling over and snapping off than the 250 gallon propane tank =)
[13:58:23] <Loetmichel_> and we found the lst pieces of smoldering wood about 50 meters from the camp fire site ;)
[13:59:20] <Jymmm> and I JUST exchanged my 40cf to an 80cf tank yesterday too, not even out of the car yet =)
[13:59:33] <Loetmichel_> i dont even WANT to be anywhere near when a 2000kg tank of propane is engulfed in a fire and decides to give way to its internal pressure buildup
[14:00:01] <Loetmichel_> +that
[14:00:53] <Loetmichel_> can you convert the cf to something metric? perferably kg?
[14:01:17] <Loetmichel_> just so i get an idea of how much liquid propane we are talking here?
[14:01:33] <Jymmm> 80CF == 2.2Cmeter
[14:01:55] <Loetmichel_> so roughly 1,8 metric tons of liquid gas?
[14:01:59] <Loetmichel_> ouch...
[14:02:09] <zeeshan> gregcnc: have you used parallel tool path before
[14:02:39] <Jymmm> 250 gallon propane tank
[14:03:08] <Jymmm> 250 gallon propane tank = 946 liters
[14:07:25] <gregcnc> xpress doesn't have parallel
[14:07:29] <Jymmm> gregcnc: Was it you that was interested in the garage wood heating results?
[14:07:35] <gregcnc> yes
[14:08:22] <sync> Jymmm: if you snap the valve off nothing will happen
[14:08:46] <Loetmichel_> sync: is that new?
[14:08:49] <sync> or "nothing" it will just vent
[14:09:00] <Jymmm> gregcnc: Untested, but cam to the conclusion that the 1/4" tubing and lil harvested radiator would give poorer-than-expected results to even bother trying, just too small and not enough volume to the system as a while. But...
[14:09:06] <Jymmm> whole*
[14:09:17] <Loetmichel_> i remember oxygen bootles falling off the roof... and landing on the valve
[14:09:26] <sync> Loetmichel_: the valves have a small diameter hole in them now
[14:09:30] <Loetmichel_> ... just to disappear up into the blue
[14:09:33] <sync> so they vent safely instead of taking off
[14:09:54] <Loetmichel_> ah, kind of a "choke"
[14:09:59] <Loetmichel_> yeah, makes sense
[14:10:11] <gregcnc> hmm i was wonderinghow much heat you can move
[14:10:33] <gregcnc> you can buy heat exchangers for like 100$ made for that
[14:10:40] <Jymmm> gregcnc: But, 1/2" copper tubing in the firebox and 100+ft of pex (aka radiate floor heating) and some of these http://www.pexuniverse.com/4ft-pex-heat-transfer-plates-htp12450 might actually HEAT the garage, not just reduce humidity, at least to soem degree
[14:11:07] <Jymmm> gregcnc: hung in ceiling area, not in floor
[14:11:34] <gregcnc> well a fan on your AC core would work
[14:11:46] <Loetmichel_> Jymmm: i once heated my self floating pool with a barbecue... works surprosingly well
[14:12:02] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=12271&g2_imageViewsIndex=1
[14:12:04] <Jymmm> gregcnc: Sure, but not enough volume in 1/4"
[14:12:10] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=12274&g2_imageViewsIndex=1
[14:12:24] <gregcnc> depends how fast you can pump hot water through
[14:12:29] <Jymmm> Loetmichel_: how long did it take?
[14:12:58] <Loetmichel_> about 5 meters of 3/8" copper pipe coiled up... and a few hours (5 iirc) and a sack of wood coal
[14:13:04] <Jymmm> Loetmichel_: I dont see a check valve?
[14:13:10] <Loetmichel_> check valce?
[14:13:15] <Loetmichel_> valve? for what?
[14:13:22] <Jymmm> for water fow
[14:13:25] <Jymmm> flow
[14:13:49] <Loetmichel_> look at the second pic right low insert
[14:13:50] <Jymmm> gregcnc: No "pump" being used
[14:14:00] <Loetmichel_> you can see the fountain pump sitting in the pool
[14:14:05] <gregcnc> that will be the limiting factor
[14:14:31] <Jymmm> Loetmichel_: gotcha
[14:14:54] <Jymmm> gregcnc: Not sure about that, it's how a coffee maker works
[14:15:15] <Loetmichel_> the red text says: "pump does roughtly a gallon a minute, intake 20°C, output 31°C"
[14:15:28] <Jymmm> gregcnc: Not doubting you, I'm really no idea, just trying to make it as minimal SPOF as posisble
[14:16:35] <Jymmm> gregcnc: We can have days without power
[14:16:57] <Jymmm> gregcnc: I can always add a pump, and use the check valve setup as a backup
[14:17:09] <Loetmichel_> Jymmm: the pool is roughly 5000 liters water (1300 gallons)
[14:17:22] <Loetmichel_> so it took not THAT long to heat it up 10°c
[14:17:24] <Jymmm> Loetmichel_: and just one bag of charcoal?
[14:17:32] <gregcnc> coffee makers is total loss, not recirculating, or is that your plan
[14:17:35] <Loetmichel_> yes, a 10kg bag
[14:18:13] <Jymmm> gregcnc: Yes, an open loop so there is no boiler effect, just gravity fed reservoir to the firebox
[14:18:18] <Jymmm> Loetmichel_: nice
[14:18:25] <Loetmichel_> gregcnc: you can make a coffee maker recirculating
[14:19:31] <Loetmichel_> The drawbacks are the fact that the tank has to be above the heating coil and the check valve and that it has to be open to the enviroment because the hot pipe is spitting out a mix of steam and boiling water so you have to have some expansion space
[14:19:55] <Jymmm> I just picked up 4CF of perlite and motar mix yesterday too. going to custom pour my own firebricks
[14:20:43] <gregcnc> so when the water begins to boil the pressure will push it out to the radiator?
[14:20:50] <Jymmm> Loetmichel_: I plan on having the reservoir on the cold return
[14:21:01] <Jymmm> gregcnc: correct
[14:21:14] <Loetmichel_> gregcnc: you could make a contraption with an (open) water tank at the roof, a pipe from there to some radiators, from there to the wood stove with the heating coil inside, then the check valve, from there back to the tank on the roof
[14:21:25] <Loetmichel_> should work flawlessly.
[14:21:40] <Loetmichel_> with the drawback that the fire has to heat up the tank before it heats the room
[14:22:40] <Jymmm> Loetmichel_: Well, not necessarily. The tank can feed the cold side to the firebox coil
[14:23:09] <Jymmm> Loetmichel_: ... so that the coil feed the radiator first
[14:23:11] <Loetmichel_> Jymmm: then the radiators have to be able to handle boinkg water and the induced pressure
[14:23:21] <dioz> boinkg
[14:23:37] <Jymmm> Loetmichel_: No, it still flows to the tank on the cold outlet
[14:23:39] <Loetmichel_> if that is checked you could pack the radiators in the "hot" pipe
[14:23:53] <gregcnc> it can't flow uphill by itself
[14:23:55] <Loetmichel_> s/boink/ boiling
[14:24:03] <Jymmm> gregcnc: it can,
[14:24:07] <dioz> it can
[14:24:34] <Jymmm> gregcnc: it's the check vavle that allows this
[14:24:37] <Loetmichel_> gregcnc https://www.youtube.com/watch?v=4j4Q_YBRJEI
[14:24:49] <gregcnc> well the boiling pressure would do it
[14:25:26] <Jymmm> gregcnc: Right, and you are trying to EXTRACT that heat so the temp will drop as well, but there still will be flow
[14:27:41] <gregcnc> well i'll be damned learned something today. i' knew of bubble pumps, but never seen their combination with boiling
[14:28:26] <Jymmm> gregcnc: =)
[14:28:52] <Loetmichel_> gregcnc: as we say in germany: "man wird so alt wie eine kuh und lernt immer noch dazu!" ;)
[14:28:57] <gregcnc> never taken apart a coffee maker either, been asking that question for years
[14:29:06] <Jymmm> gregcnc: You should take apart an old coffee maker sometime, it's really quite interesting in the parts and design, thermally, electrically, etc
[14:29:20] <gregcnc> never owned one
[14:29:46] <Jymmm> gregcnc: YOU COMMY BASTARD!!!! no coffee maker?! WTF?! lmao
[14:30:11] <Loetmichel_> Jymmm: i opted for the fully auto thingy...
[14:30:17] <gregcnc> been using aeropress since I started drinking coffee
[14:30:17] <Jymmm> Loetmichel_: lol
[14:30:32] <Jymmm> gregcnc: is that like a french press?
[14:30:36] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=12721&g2_imageViewsIndex=1 <- i am lazy that way ;)
[14:30:49] <gregcnc> sort of
[14:31:02] <gregcnc> you pres it directly into your mug
[14:31:24] <Jymmm> gregcnc: h, I see it now, k
[14:31:39] <gregcnc> flavored coffee... blasphemy!!
[14:32:13] <Jymmm> Loetmichel_: that was a great video find btw
[14:32:25] <Loetmichel_> gregcnc: the pistacio syrup is actually quite nice in coffee. wouldnt have thought that myself ;-)
[14:33:10] <Loetmichel_> thy
[14:33:49] <gregcnc> aeropress is patented by the guy that patented aerobie
[14:35:26] <gregcnc> loet i've never heard that!
[14:37:13] <Jymmm> gregcnc: So, do you have a better idea of what I'm attempting now?
[14:37:50] <gregcnc> yes. I keep thinking of testing somehow before going all out
[14:37:58] <Jymmm> gregcnc: get as many BTUs out of the firebox and into the garage as possible =)
[14:38:40] <Jymmm> gregcnc: I know it actually works, now it's just a matter of how well it works
[14:38:44] <Jymmm> =)
[14:39:08] <gregcnc> right, getting water flow and heat in/out of the exchangers right
[14:39:18] <gregcnc> and air
[14:39:34] <Jymmm> gregcnc: running 1/4 vs 1/2 is a matter of volume transfer, which is directly related to btu's transfered
[14:39:59] <gregcnc> water temp is limited to boiling so you have to move a lot of water
[14:40:08] <Jymmm> which is actually how I can control the heat in the garage as well
[14:40:44] <gregcnc> i'd have to do the math to get a better idea
[14:40:48] <Jymmm> gregcnc: there will be a LOT of heat loss along the way, so speed isn't that much of an issue, plus this is over time, not "instant heat"
[14:41:31] <Jymmm> gregcnc: And "boiling" for me is 207F too, not 212F
[14:42:00] <gregcnc> agree, but if flow is low you can only get so much heat out no mater how much you put in
[14:42:52] <Jymmm> gregcnc: True, but like I said I cna start with the check valve setup, and add a pump later one for mor eflow.
[14:43:00] <Jymmm> on*
[14:43:24] <Jymmm> but I want to be "worse cae" aas in during a power outage
[14:43:40] <gregcnc> then you need a big passive radiator
[14:43:46] <Jymmm> anything better is just iccing on the cake
[14:43:56] <Jymmm> gregcnc: radiant cieling heating =)
[14:44:10] <Jymmm> aka http://www.pexuniverse.com/4ft-pex-heat-transfer-plates-htp12450
[14:44:34] <gregcnc> I think near the ground would provide some circulation in the shop otherwise cold air will be cold on the floor
[14:44:56] <Jymmm> No floor space, so going in the cailing area
[14:45:22] <gregcnc> on the wall?
[14:45:32] <Jymmm> heat will eventually fill top- down
[14:46:02] <Jymmm> Cant do wall either, they are "double parked" =)
[14:47:42] <Jymmm> I have these chrome racks that go from floor to rafters that line the walls. behind them is long term storage, like materials, wood, etc. I cna just roll out a rack if I need to get to them.
[14:48:49] <Jymmm> gregcnc: I have like 6 of theses https://images-na.ssl-images-amazon.com/images/I/41U6VxuMb%2BL._AC_UL320_SR248,320_.jpg
[14:49:09] <Jymmm> 18" deep x 48" wide
[14:51:07] <Jymmm> Loetmichel_: How many gpm was the pump you used?
[14:51:32] <Loetmichel_> as i said above: roughly one gallon per minute
[14:51:52] <Loetmichel_> a small submersible fountain pump
[15:01:44] <Jymmm> Loetmichel_: and the coper tubing... diameter and length?
[15:02:02] <Jymmm> Loetmichel_: sorry if I missed this info above
[15:02:27] <Loetmichel_> about 5 meters of 10mm tube (15 feet of 3/8")
[15:02:38] <Loetmichel_> the rest normal garden hose
[15:02:52] <Jymmm> Loetmichel_: Cool, so 1/2" should be more than plentiful
[15:03:08] <Loetmichel_> yes
[15:03:41] <Jymmm> Loetmichel_: You should do a writeup on it, it would help a lot of people I'd suspect.
[15:04:32] <Jymmm> Loetmichel_: I'm actually a bit surprised you only needed 10kg of charcoal, I would have expected a lot more
[15:05:04] <Loetmichel_> i was surprised myself
[15:05:33] <Jymmm> Loetmichel_: I'll be converting a newspaper rack into an outdoor firebox =)
[15:06:01] <Loetmichel_> Jymmm: have you thought about a simple "bullerjan" for inside your workshop?
[15:06:13] <Jymmm> Loetmichel_: a what?
[15:06:20] <Loetmichel_> or arent you allowed to put a chimney outside?
[15:06:24] <Loetmichel_> google it ;)
[15:06:44] <Jymmm> Loetmichel_: Oh, a barrel stove.
[15:07:00] <Loetmichel_> barrel stove with hot air pipes added
[15:07:06] <Jymmm> Loetmichel_: I can, but scars the fuck out of me to have the firebox indoors
[15:07:11] <Jymmm> scares*
[15:07:25] <Loetmichel_> the pipes go great lenghts to increase the efficiency of the barrel stove
[15:07:39] <Jymmm> Loetmichel_: I only have 374 sq ft of floor space, and that really is maxed out.
[15:07:44] <Loetmichel_> AND to cool downt the barrel walls
[15:08:06] <Jymmm> Loetmichel_: I also dont want to breath that shit =)
[15:08:29] <Loetmichel_> i think you could mount the bullerjan outside and elongate the tubes to get a "hot air heating system"
[15:08:51] <Loetmichel_> if you have the means to drill a dozen 3" holes into your wall
[15:09:26] <Loetmichel_> that would save space inside AND have the fears of breathing in CO
[15:09:27] <Jymmm> Loetmichel_: haha, I just spent all summer sealing all the holes/cracks in the exterior walls of the garage
[15:09:46] <Loetmichel_> have you google the bullerjan?
[15:09:52] <Loetmichel_> and know how it works?
[15:09:55] <Jymmm> Loetmichel_: yes, I see the pics
[15:10:14] <Jymmm> no idea on it's operation.
[15:10:29] <Loetmichel_> the bent pipes heat up air inside
[15:10:44] <Loetmichel_> hot air floats up, so more cold air gets sucked in the lower end
[15:10:58] <Loetmichel_> repeat as long as enough heat is in the fire box ;)
[15:11:15] <Loetmichel_> so no danger of getting fire fumes in the air supply
[15:11:27] <Loetmichel_> the tubes are completely sealed to the firebox
[15:11:51] <Jymmm> Loetmichel_: Right, like a boiler inside-out so to speak, using air instead of water
[15:11:53] <Loetmichel_> AND dont need a pump of any sort ;)
[15:11:57] <Loetmichel_> yes
[15:12:34] <Loetmichel_> only drawback there: you have to find a way to get a dozen tubes connected to the top and bottom of your garage wall
[15:12:34] <Jymmm> Loetmichel_: 1) I dont have a source for the tubes, 2) I dont have a way to bend them
[15:13:00] <Jymmm> Loetmichel_: ...and install LOTS of heat shielding
[15:13:02] <Loetmichel_> was just an idea
[15:13:21] <Loetmichel_> because those bullerjans are fairly inexpensive
[15:13:24] <Jymmm> Loetmichel_: no worries, I'm totally open to any/all realistic ideas. Which that one is.
[15:14:32] <Jymmm> Loetmichel_: heh, they kinda look like car engines in a way =)
[15:14:47] <Jymmm> with "exhaust pipes" sticking up
[15:15:28] <Kevin`> there are plenty of commercial heat exchanger systems
[15:15:39] <Kevin`> I doubt you HAVE to build one
[15:15:41] <Jymmm> Loetmichel_: I guess someone else thought so too... https://c1.staticflickr.com/5/4022/4655918342_7ca83166ce_b.jpg
[15:16:01] <Jymmm> Kevin`: Insert YOUR credit card here --> [ ]
[15:16:33] <Loetmichel_> :-)
[15:17:19] <Jymmm> Loetmichel_: Hmmm, interesitng... http://wd.ua/uploads/posts/2015-09/1442824825_img_8506__tehno_pr.jpg
[15:19:04] <Loetmichel_> yeah, that would work similar
[15:32:28] <Tom_L> not as sexy
[15:37:26] <CaptHindsight> paint it blue since it's the hottest color
[15:38:07] <Jymmm> CaptHindsight++ ("warmest" btw)
[15:38:58] <CaptHindsight> Jymmm: I use the hotness scale for situations like these
[15:40:23] <CaptHindsight> http://superuser.com/questions/671249/does-the-color-of-a-heatsink-affect-its-performance-in-dissipating-heat
[15:42:07] <Tom_L> do the touch test
[15:42:24] <CaptHindsight> https://www.britannica.com/science/Stefan-Boltzmann-law
[16:21:12] <witnit> JT-Shop: thanks for always shipping so fast!
[16:22:03] <Jymmm> Tom_L: LICK IT ;)
[16:22:31] <XXCoder> Meduza: nice lol
[16:26:20] <Meduza> XXCoder: it is actually turning out pretty nice :p
[16:29:12] <MacGalempsy> question. how would I go about disabling the following error on an A axis? The encoder is out, but it rotates when I jog it.
[16:29:58] <MacGalempsy> I want to cut a couple of screws with the mill, and give it a little jog.
[16:31:47] <XXCoder> med, I'd have asked you how it sound like when done but I havent heard anything for last 40 years and it wont change anytime soon lol
[16:32:22] <JT-Shop> witnit: that is one of the things I want to be known for
[16:33:03] <XXCoder> JT-Shop: I found better clip :D https://www.thingiverse.com/thing:1854540
[16:33:11] <JT-Shop> dang power supply was going nuts today and made me think my laptop was going bonkers... spent the whole day chasing that one
[16:33:38] <JT-Shop> XXCoder: have you printed one?
[16:33:48] <XXCoder> not yet, plan to today
[16:33:58] <XXCoder> see if it works, then I plan to print a few
[16:34:31] <JT-Shop> I quit hitting the download all button lol
[16:35:00] <XXCoder> yeah? something had huge useless file? heh
[16:35:28] <Meduza> That looks like a quite nice idea for a wire clip actually
[16:36:01] <JT-Shop> saves me time not having to chase the stl file down through a zip file
[16:36:15] <XXCoder> yeah and looks like insertable and removable without disassembly too
[16:36:34] <Meduza> i would probably have made the base a bit longer so it would not twist easily
[16:39:23] <JT-Shop> let you know in 10 minutes or so
[16:45:44] <nubcake> having only ssh access to a raspberry(raspbian), how can i check the size of the card (not just the partition)
[16:48:55] <XXCoder> jt ok
[16:54:22] <Deejay> gn8
[17:00:00] <JT-i3> it's a little loose fitting in the 2020
[17:00:14] <XXCoder> can slip out or?
[17:00:31] <JT-i3> yea
[17:02:11] <XXCoder> interesting'
[17:02:18] <XXCoder> would it hold wires fine?
[17:02:24] <JT-i3> just needs to be scaled up a bit I think
[17:03:33] <JT-i3> I scaled it to 110%
[17:04:56] * JT-i3 needs to invent an auto butt wipe for the nozzle
[17:06:25] <JT-i3> my wife bought some Halloween wine glasses for the bond fire tonight
[17:06:56] <BeachBumPete> bond?
[17:06:58] <Jymmm> JT-i3: 44 ounce ones?
[17:07:16] <Jymmm> BeachBumPete: bond fire = BIG ASS FIRE
[17:07:31] <JT-i3> something like that pete
[17:07:38] <XXCoder> with some volkwagon engine part in it?
[17:07:43] <BeachBumPete> isnt that bonfire?
[17:07:54] <Jymmm> XXCoder: he wishes =)
[17:08:03] <XXCoder> lol
[17:08:18] <JT-i3> well that too but you should see the pile of wood I brought over the other day
[17:08:25] <Jymmm> gott alove an angine blocks wirth of magnesium on fire =)
[17:08:39] <Jymmm> JT-i3: brought? Not gathered?
[17:08:53] <JT-i3> 5x10 trailer piled 4' high with wood and the back of the pickup full
[17:09:07] <Jymmm> JT-i3: Not enoug on your land?
[17:09:13] <JT-i3> crap I didn't want to split for firewood
[17:09:27] <Jymmm> ah, haha, yeah I totally get that.
[17:09:52] <Jymmm> The kid across the street moved, and he was a damn good/cheap wood splitter too =)
[17:10:13] <JT-i3> if I don't have any wood I'll burn everything, when I have a shit load of wood I get a little picky
[17:10:42] <Jymmm> JT-i3: is your house full wood heating?
[17:11:03] <JT-i3> XXCoder: might try 101%, 110% is way too big lol
[17:11:08] <XXCoder> lol
[17:11:23] <XXCoder> hpefully you didnt print 20 of em ;)
[17:11:31] <JT-i3> no, just the one
[17:11:58] <JT-i3> just the garage, shop, and new shop
[17:12:41] <JT-i3> if I knew how easy it was to split firewood with the Mean Green Splitting Machine I would have built a hardy for the house
[17:13:14] <XXCoder> http://www.optipess.com/2016/10/17/halloween-horror/ heh
[17:13:20] <Jymmm> JT-i3: looking...
[17:13:48] <Jymmm> JT-i3: oh, using your PTO. I don't have a tracotr
[17:14:53] <Jymmm> It looks easy, but slow https://www.youtube.com/watch?v=A4TfMwl6x40
[17:16:16] <Jymmm> THE ONE THING that *REALLY* kills me about firewood, is the handling. OH MY GAWD you have to handle each piece of firewood at LEAST 20 times before it hits the firebox
[17:17:23] <XXCoder> well you gonna gladhandle em till they are happy enough to die in fire lol]\
[17:17:49] <andypugh> Cams without CAM : https://goo.gl/photos/UU9sxWu1wep55uPR9
[17:18:09] <andypugh> That was by setting a parameter to 101100111 in the G-code.
[17:18:58] <Jymmm> XXCoder: say that agian?
[17:19:10] <XXCoder> nah was stupid joke
[17:21:24] <andypugh> You might be able to count how many goes I had at it to get the G-code working.
[17:21:25] <andypugh> (Guess what the material is)
[17:21:25] <andypugh> Jymmm: You need a genetically modified tree that grows continuously into the stove.
[17:21:44] <XXCoder> milling wax
[17:22:31] <Jymmm> andypugh: haha, great idea. Too bad I'd rather have monsanto cease to ever exist.
[17:23:13] <Jymmm> andypugh: Although... I wonder if that would actually be possible using bamboo?
[17:23:22] <nubcake> Jymmm: +1
[17:23:57] <Jymmm> sme specieis of bamboo can grow in feet per day
[17:24:04] <andypugh> XXCoder: Did the wick give it away?
[17:24:40] <XXCoder> didnt see that lol I just figured from look of chips and material
[17:27:42] <andypugh> It will be brass eventually, but at £70 per blank I wanted a cheap practice
[17:27:51] <XXCoder> makes sense.
[17:28:00] <XXCoder> http://www.optipess.com/2016/06/20/flipping-out/ brilliant. lol
[17:28:59] <JT-i3> Jymmm: no pto splitter
[17:30:03] <JT-i3> XXCoder: actually 110% is still too small
[17:32:07] <JT-i3> Jymmm: firewood heats you up multiple times be glad it does and cut your firewood in the winter lol
[17:34:30] <JT-i3> the wife got a mask for me for tonights Halloween party so I don't scare anyone
[17:35:35] <XXCoder> jt weird
[17:35:41] <JT-i3> lol
[17:35:43] <XXCoder> did you forget to re-export gcode? heh
[17:35:58] <JT-i3> no
[17:36:07] <JT-i3> doing one at 115% now
[17:36:08] <XXCoder> happened to me lol
[17:36:20] <JT-i3> oh yea done that before
[17:36:37] <JT-i3> wife made devilish eggs with eyes and blood
[17:37:54] <andypugh> I am a haloween refusenik.
[17:38:13] <andypugh> I hate it.
[17:38:25] <andypugh> And I especially hate having to hide indoors with the lights off.
[17:38:32] <XXCoder> too scary? lol
[17:38:37] <XXCoder> kidding. laters
[17:38:43] <JT-i3> just an excuse for the OTH biker gang to gather and have fun
[17:39:06] <andypugh> No, I just have no desire for any interaction with other people’s kids.
[17:39:19] <JT-i3> andypugh: you should live out in the woods where children are afraid to come out after dark
[17:39:51] <andypugh> Especially as we didn’t have trick or treat when I was a kid so I have _no_ idea what the rules are
[17:40:10] <JT-i3> when we lived in civilized place the universal sign for no candy here is the porch light is off
[17:40:12] <andypugh> It’s a recent import from the US
[17:40:38] <JT-i3> damn americans
[17:40:59] <JT-i3> XXCoder: you fit some print fans yet?
[17:49:14] <witnit> from start to finish it only took me about 20 minutes to get that 7i80 up and running, I figured I would be at this alot longer
[17:51:03] <JT-i3> XXCoder: try 120%, 115% is a fair fit but a tad loose
[17:55:09] <witnit> JT-i3: are you planning on getting any of the usb based controls on hand?
[18:42:08] <Flipp_> hey all. anyone ever heard of Wilton brand lathes?
[18:57:23] <pfred1> I've heard of Wilton vises
[18:57:41] <pfred1> is it the same wilton?
[18:57:55] <pfred1> Wilton makes the pinnacle of vises
[19:12:23] <Jymmm> YAY! Go the new 80Cf tank chained to the wall and made a lil makeshift cart for it =)
[19:12:30] <Jymmm> s/Go/Got/
[19:13:06] <pfred1> litle baby bottle
[19:15:40] <Jymmm> pfred1: Well, bigger than the 40Cf I had
[19:16:28] <pfred1> I acquired a 330cuft tank
[19:17:04] <pfred1> that's my argon then i have a 244 oxidizer
[19:17:11] <Jymmm> pfred1: I was able to exchange my 40cf nitrogen plus an expired 40CF acetaleyene I had for the 80Cf nitrogen straight across plus the cost of the gas
[19:17:19] <jdh> baby bottle. I have 4 440ft^3 bottles
[19:17:54] <pfred1> 330 is big enough for me it is all I can carry
[19:18:17] <Jymmm> and I can tossed in the back of the SUV easily
[19:18:20] <jdh> these are only slightly bigger, they are 4500psi
[19:19:12] <jdh> Jymm: http://www.artichoke.org/vw.jpg
[19:19:32] <Jymmm> jdh: what size are those?
[19:19:47] <jdh> 330ish
[19:19:51] <Jymmm> ah
[19:19:55] <jdh> the silver ones are a little bigger
[19:19:59] <jdh> o2 and helium
[19:20:06] <Jymmm> lol I see the "DON NOT DROP" on the cardboard, kinda funny
[19:20:35] <Jymmm> jdh: helium for diving?
[19:20:36] <jdh> that was when I had a brief moment of sanity issues and bought a VW
[19:20:43] <jdh> yeah.
[19:20:53] <jdh> I can fit 5 easily in my Yukon
[19:20:59] <Jymmm> jdh: Well, they fit, that's the good thing at least
[19:21:32] <jdh> I have 5 o2, 3 He, 8 banked gas
[19:21:46] <Jymmm> jdh: fFor your next trick, try carrying them =)
[19:22:40] <Jymmm> I've been using a 10" crest wrench, what is the proper size wrench for CGA-580 (?)?
[19:22:56] <Jymmm> (or is that 540?)
[19:23:03] <jdh> a 14" crescent wrench
[19:23:04] <pfred1> I always used an adjustable on my regulators
[19:23:13] <jdh> 580 is inert, 540 is o2
[19:23:15] <pfred1> I think a 12"
[19:23:32] <Jymmm> pfred1: 10" works
[19:23:40] <Jymmm> ok, 580
[19:23:41] <pfred1> not like my Bacho
[19:24:40] <R2E4> Hi all
[19:25:10] <R2E4> Looking for info on joint-axes
[19:26:07] <R2E4> Is it included in 2.7.7?
[19:27:56] <pfred1> that was fast
[19:28:10] <Jymmm> pfred1: you musta scared em away
[19:28:20] <pfred1> I didnna say a thing
[19:28:28] <Jymmm> pfred1: EXACTLY
[19:28:48] <Jymmm> pfred1: take off your halloween custom next time
[19:28:56] <Jymmm> costume*
[19:30:06] <pcw_home> R2E4: JA? is 2.8+ only

[19:32:21] <Jymmm> ...companion to the video lecture
[20:08:44] <witnit> after switching to PREEMPT my latency jumped up to 65,000 I never ran a machine with this latentcy should I be concerned?
[20:10:14] <witnit> 64,684 servo thrd
[20:10:14] <witnit> 71,180 base thrd
[20:10:49] <pfred1> I have an intermittant latency issue I'd love to track down
[20:11:11] <pfred1> it is very long and sporadic
[20:11:27] <witnit> which kernal you on?
[20:11:37] <pfred1> beats me 3.2 maybe?
[20:11:47] <witnit> uname -v
[20:11:49] <witnit> in terminal
[20:11:53] <pfred1> whatever cradek's distro has in it
[20:12:03] <pfred1> that machine is disassembled ATM
[20:12:11] <pfred1> I moved my machine
[20:13:08] <pfred1> it still isn't quite all back together yet either
[20:13:48] <pfred1> I am installing new motor drives and putting them into a whole new controller box
[20:13:53] <CaptHindsight> witnit: what was your latency with RTAI?
[20:13:56] <pfred1> so that takes time
[20:14:07] <witnit> CaptHindsight: 15-20k
[20:14:10] <pfred1> oh yeah new PSU too
[20:21:41] <pcw_home> witnit: latency may or may not be significant, depends on the hardware
[20:24:42] <pfred1> my machine hiccup doesn't seem to affect much other than to pop up the unexpected real time delay warning
[20:24:43] <andypugh> Flipp_: Nothing about Wilton on “The Best Web Site in The World” http://www.lathes.co.uk
[20:24:52] <pcw_home> also the latency test doesn't actually do anything, real latency for I/O is often noticeably worse
[20:26:17] <andypugh> witnit: PREEMPT is generally worse than RTAI. Whether it matters depends on your system. 65k might be a disaster for software stepping, but no problem for an FPGA card system.
[20:26:26] <andypugh> But, why did you change?
[20:28:31] <pfred1> I might try acpi=ht when i get my system going again
[20:29:39] <enleth> hm, I'm doing the very first in-system tests with the new drives and 7i77 on my bridgeport and the X drive is acting funny
[20:30:14] <alex4nder> like, it's telling jokes?
[20:30:26] <pfred1> I was thinking there's always a comedian
[20:31:27] <enleth> when I give it 5V using the open loop test tool in pncconf (by setting the Fast DAC speed to 5) and hold the + button, it jerks the servo forward by a turn or so and stays there at idle current; when I let go of the button, it jerks back to more-or-less the previous position
[20:31:37] <enleth> the - button jerks it in the opposite direction
[20:32:00] <enleth> curiously, reversing the tacho does not cause a runaway
[20:32:56] <enleth> I haven't bench tested this particular servo drive, which means the trimpots could very well be set to something stupid
[20:33:45] <enleth> I'll swap it for a tested and more-or-less tuned one, but I'm curious what is actually happening with this one
[20:34:02] <pfred1> swapping is a valid troubleshooting technique
[20:34:49] <witnit> pcw_home: andypugh_ Im using the 7i80, 7i33, 7i37 combo with servo systems
[20:34:53] <pfred1> ah our buddhist monk is back
[20:35:04] <witnit> andypugh: *
[20:43:02] <andypugh> witnit: 65k is fine with a Mesa card
[20:44:25] <enleth> yep, it must have been the pots on the drive, the other one absolutely does work
[20:44:44] <pfred1> enleth congratz on sussing it out
[20:45:05] <pfred1> now just set the pots on the funny drive like the good one is
[20:45:08] <enleth> well, the X axis on my bridgeport is now officially powered by LinuxCNC
[20:45:16] <enleth> on to Y and Z
[20:54:06] <nubcake> night everyone
[20:54:28] <andypugh> In case you are not subscribed, there was a new Cliclspring video on YouTube today: https://www.youtube.com/watch?v=NsnLVYwqESM
[20:54:53] <gregcnc> watched it with the kids already
[20:56:56] <enleth> http://imgur.com/a/FxxAs - current progress with the retrofit
[20:59:33] <SpeedEvil> enleth: :)
[21:07:55] <enleth> there's one interesting side effect of replacing the old shitty SCR-based servo drive with a modern DC H-bridge drive
[21:08:07] <enleth> the servo is almost completely silent at low speeds
[21:39:52] <enleth> so X works, Y and Z still need some work
[21:40:19] <enleth> spindle control almost works - I need to figure out how to configure separate start and stop outputs
[21:40:37] <enleth> (the spindle is controlled by a latching relay here)
[21:40:49] <tiwake> meh
[21:41:04] <tiwake> this guy is confusing configuration file with program with machine controller
[21:41:48] <tiwake> I'm kinda tired of trying to tell this guy that knowing the configuration file won't help him do what he wants, and that he needs to build a new controller for it
[21:41:50] <Jymmm> OH DAMN... he blew that iron ball into pieces using ice!!! =)
[22:02:47] <witnit> andypugh: im not really sure for some reason I was thinking I needed pre to run an eth card, that is not so?
[22:03:12] <andypugh> Yes, that is the case
[22:03:14] <witnit> well then
[22:03:24] <witnit> was that ever the case?
[22:03:33] <witnit> or not the case hahah
[22:04:01] <witnit> I dont know why I was thinking I needed pre for it, is there some card I would ever need it for?
[22:04:31] <andypugh> No, you do need “uspace” to use an ehternet card.
[22:04:51] <witnit> welp, I guess I know how to do it though
[22:05:42] <witnit> do the usb cards perform different or need anything special?
[22:06:01] <andypugh> LinuxCNC doesn’t support any USB cards
[22:06:23] <witnit> oh, bummer, is it in the works?
[22:06:42] <andypugh> No, and never will be. USB introduces random delays
[22:07:51] <witnit> so 7i43H?
[22:08:45] <andypugh> No, will never work.
[22:10:24] <andypugh> You can use a 7i43 on the parallel port though, that works well.
[22:12:12] <witnit> okok, how about this trick the eth connections into using wifi, latency aside could it function?
[22:12:17] <skunkworks_> andypugh, he is amazing and patient..
[22:12:21] <witnit> hahahah
[22:14:07] <andypugh> The card probably couldn’t tell it was on WiFi. It might well function. I am not sure that’s the same as working.
[22:14:52] <witnit> it would be a fun quadcopter type of test
[22:15:21] <andypugh> Anyway, even with the bonus hour of sleep with the welcome return to the _actual_real_time_ rather tham lying by an hour, it’s time for me to depart.
[22:15:21] <witnit> very low weight complete servo system with programable waypoints
[22:15:29] <witnit> thanks cu!
[22:19:30] <zeeshan> man there is a lot of hydraulics on the lathe
[22:19:33] <zeeshan> not even sure where to start!
[22:19:34] <zeeshan> =[
[22:20:05] <witnit> what lathe you got?
[22:20:36] <zeeshan> nakamura tome tmc-3
[22:20:39] <zeeshan> trying to retrofit
[22:20:44] <zeeshan> ive searched for manuals over the year
[22:20:46] <zeeshan> nothing to be found
[22:22:58] <witnit> what year is it?
[22:24:34] <zeeshan> 83
[22:26:35] <skunkworks_> zeeshan, our big mill used to be all hydraulic - even down to the servos... We are still using most of the hydraulics
[22:27:00] <zeeshan> this i think uses dc motors w/ tachometers
[22:27:21] <zeeshan> but the tail stock, chuck, etc
[22:27:23] <zeeshan> use hydraulics
[22:27:34] <zeeshan> it looks like the gear shifter for the trans is also hydraulic..
[22:27:39] <zeeshan> theres like 40 hyd hoses =/
[22:28:10] <enleth> zeeshan: did you get the pump as well?
[22:28:16] <zeeshan> the powerpack?
[22:28:16] <zeeshan> yea
[22:28:24] <zeeshan> gotta change the motor to single phase tho
[22:28:29] <enleth> does it work?
[22:28:32] <zeeshan> yea
[22:28:39] <zeeshan> machine was running when i bought it
[22:28:44] <zeeshan> i gotta go from 3 phase to 1 phase tho
[22:28:56] <zeeshan> i need manuals tho
[22:28:59] <zeeshan> was missing
[22:29:26] <enleth> is it so complex it can't be reverse engineered?
[22:30:52] <zeeshan> everything can be reverse engineered!
[22:30:56] <zeeshan> problem is time
[22:31:01] <zeeshan> i'd like to spend 4 months max on the conversion
[22:31:59] <zeeshan> with the mill
[22:32:10] <zeeshan> my approach figure out each component/sensor till i had no more wires left
[22:32:20] <zeeshan> this ones going to be a bit more difficult cause of the hydraulics
[22:32:39] <skunkworks_> http://electronicsam.com/images/KandT/conversion/hydaulic.JPG
[22:32:53] <zeeshan> haha
[22:32:56] <zeeshan> mine looks similar to that
[22:33:24] <pink_vampire> linux cnc support at that type of servos? http://imgur.com/gallery/ew0pdFs
[22:33:39] <R2E4> Hey Zeehan
[22:33:47] <R2E4> zeeshan
[22:33:56] <zeeshan> hi :]
[22:34:40] <R2E4> you up to date on the latest 2.7.7?
[22:34:44] <zeeshan> nope
[22:34:51] <R2E4> lol
[22:34:55] <skunkworks_> we used to have to cool the oil when the spindle/servos where hydraulic.. now we don't
[22:34:59] <zeeshan> 2.7.2 i think
[22:35:16] <zeeshan> you converted to electric servos?
[22:35:37] <R2E4> no, building a servo machine
[22:36:21] <zeeshan> skunkworks_: do you have experience with lathe turrets
[22:36:23] <zeeshan> and how they work?
[22:37:17] <skunkworks_> we have a cincinati malicron lathe that we hope to convert.. but have not looked to far into it. (2 turrets)
[22:37:35] <zeeshan> http://i.imgur.com/zGFsvLY.jpg
[22:37:36] <witnit> well figure it out zeeshan I got this mazak coming up and it looks just like what you got
[22:37:38] <zeeshan> thi sis what i see on the turrett
[22:38:00] <zeeshan> ii guess that is the motor that indexes the turrett?
[22:38:10] <zeeshan> and that pancake thing with a hydraulic fittign in it
[22:38:12] <zeeshan> or something like that
[22:38:15] <zeeshan> is a locking mechanism
[22:38:39] <zeeshan> http://i.imgur.com/7FTPMhJ.jpg
[22:38:42] <zeeshan> i look this pic before the move
[22:38:46] <zeeshan> see all the goddamn hydraulics?
[22:38:48] <witnit> http://www.patelmachinery.com/mazak-quick-slant-30-4-axis-pr78-prc1.html#image
[22:38:57] <zeeshan> nice witnit
[22:39:05] <zeeshan> im learning mazatrol in the next couple of weeks
[22:39:19] <zeeshan> we got mazaks coming at work, need to figure out their capabilities
[22:39:55] <zeeshan> hmm
[22:39:59] <zeeshan> x1 x2? z1 z2?
[22:40:01] <zeeshan> 4 drives?
[22:40:22] <zeeshan> o. twin turrett!
[22:40:23] <zeeshan> nice!
[22:40:25] <witnit> yah :)
[22:40:35] <zeeshan> you can do some crazy shit with that
[22:40:43] <zeeshan> like turn a really long thin bar
[22:40:48] <witnit> has conveyor still but no flex arm thing
[22:40:49] <zeeshan> by machining both sides
[22:41:09] <witnit> I could use one as a follower with rollers and then the other cutting
[22:41:42] <witnit> but they ran hard material on it and the ways are really badly worn I would need to do some serious work to get them right or do my best to program out the problems
[22:42:00] <zeeshan> scraping :)
[22:42:26] <witnit> they are like... .150 drop in places hahaha
[22:42:43] <witnit> a ski slope
[22:42:49] <witnit> with ruts
[22:43:44] <zeeshan> lol
[22:44:04] <zeeshan> http://i.imgur.com/slg9m6U.jpg
[22:44:06] <zeeshan> this picture makes me lol
[22:44:11] <zeeshan> damn thing is in my garage
[22:44:56] <witnit> hahahah its beautiful, but sadly you have to walk outside to load a 12" bar
[22:45:03] <zeeshan> not anymore!
[22:45:09] <zeeshan> its along the side now
[22:45:12] <zeeshan> car goes in the middle
[22:45:15] <witnit> oh, very good
[22:45:28] <zeeshan> bar would go over the welding table tho
[22:45:29] <zeeshan> =[
[22:45:35] <zeeshan> can't weld and machine!
[22:45:59] <zeeshan> are you going to retrofit?
[22:46:12] <witnit> yes, in time, I have so many other projects currently
[22:46:16] <witnit> it just sits for now
[22:47:09] <zeeshan> hehe
[22:47:19] <witnit> it takes alot of amps to run the spindle and I have not yet gotten a big enough disconnect for it
[22:47:41] <zeeshan> http://i.imgur.com/S4BpCcK.jpg
[22:47:45] <zeeshan> these are the original servo drives
[22:47:48] <zeeshan> im planning to reuse them
[22:47:56] <zeeshan> on ebay they go for 120-250$
[22:48:01] <zeeshan> so it's worth using
[22:48:05] <zeeshan> cause cheap to replace
[22:49:26] <witnit> is something like this for my spindle http://i.ebayimg.com/images/i/141657996912-0-1/s-l1000.jpg
[22:49:51] <zeeshan> haha
[22:49:59] <zeeshan> i remember discussing my spindle motor here
[22:50:06] <zeeshan> but i totally forgot what type it is
[22:50:11] <zeeshan> for sure it's not a dc servo
[22:50:27] <witnit> that would be one hell of a generator
[22:50:28] <witnit> :)
[22:51:56] <zeeshan> http://i.imgur.com/oH2zCdh.jpg
[22:52:08] <zeeshan> !
[22:52:08] <zeeshan> =]
[22:52:36] <witnit> I can only assume these two machines are very similar, if I make any breakthroughs with mine I will let you know :)
[22:52:43] <witnit> which cards are you planning to use for the build?
[22:52:47] <zeeshan> mesa
[22:52:54] <witnit> do you know which ones yet?
[22:53:00] <zeeshan> 7i77 + 6i25
[22:53:01] <zeeshan> likely
[22:53:15] <R2E4> That the ethernet one?
[22:53:21] <zeeshan> no
[22:53:23] <zeeshan> regulator
[22:53:26] <zeeshan> *regular
[22:53:31] <AndChat|234416> hey
[22:53:37] <zeeshan> http://imgur.com/a/w4VTf
[22:53:41] <zeeshan> this is the spec of the spindle motor
[22:53:46] <zeeshan> it clearly says 200V 3 phase on it
[22:53:59] <zeeshan> i have no idea how the original spindle drive was controlling it as C axis.
[22:54:08] <witnit> mine will likely be 7i90+7i48+7i37
[22:54:15] <zeeshan> why that combo
[22:54:37] <R2E4> Whats the diff between the 6i25 and 5i25?
[22:54:40] <witnit> I got lots of pieces around that match and are easy to swap around
[22:54:44] <zeeshan> one goes in pci slot
[22:54:47] <zeeshan> the other goes in a pci-e slot
[22:54:53] <R2E4> ah
[22:55:33] <zeeshan> man this is going to be nuts
[22:55:37] <zeeshan> the motor is 15kW
[22:55:41] <R2E4> 6i25 is for steppers no?
[22:55:58] <R2E4> nevermind
[22:56:11] <zeeshan> no
[22:56:28] <witnit> I was planning on starting my retrofit without the spindle anyhow and get everything else working...
[22:56:39] <zeeshan> what is your spindle motor size
[22:56:44] <witnit> that will give me the ambition to run a heavy line back
[22:56:45] <zeeshan> for me to run this spindle motor on single phase
[22:56:47] <witnit> I funno
[22:56:49] <zeeshan> i need frigigng a 100A breaker.
[22:56:52] <zeeshan> just for the spindle motor
[22:57:00] <zeeshan> i might have to downgrade to a 7.5kW motor or something
[22:57:32] <MacGalempsy> is this a home project or work project?
[22:57:33] <witnit> you have to consider the draw on the amps wont exactly be small either
[22:57:37] <zeeshan> MacGalempsy: home
[22:57:54] <witnit> for the turrets
[22:57:55] <MacGalempsy> this is the lathe you picked up?
[22:58:01] <zeeshan> witnit: yes
[22:58:06] <zeeshan> MacGalempsy: yea last year
[22:58:07] <witnit> those are pretty big motors if they all move at once
[22:58:13] <zeeshan> going to start working on it soon
[22:58:15] <zeeshan> winter project :)
[22:58:18] <zeeshan> witnit: exactly
[22:58:21] <zeeshan> each servo is 2kW
[22:58:26] <zeeshan> er servo drive is 2kW
[22:58:37] <MacGalempsy> i was just wondering what kind of service you have at home
[22:58:47] <zeeshan> 3kW for hydraulic power pack..
[22:58:53] <zeeshan> and prolly another 2kW for misc stuff.
[22:58:58] <zeeshan> 24kW total
[22:59:13] <zeeshan> 100-120A breaker prolly
[22:59:46] <zeeshan> MacGalempsy: service is 200A
[22:59:48] <witnit> well your neighbors might complain when their lights all dim when you make that first heavy cut :)
[22:59:56] <MacGalempsy> lol
[23:00:00] <zeeshan> honestly, im just thinking of keeping this motor
[23:00:08] <zeeshan> and running it with a 7.5kW spindle drive
[23:00:27] <zeeshan> i've done some serious cuts on a 7.5kW motor before
[23:00:30] <zeeshan> i dont think i need 15kW
[23:00:37] <MacGalempsy> witnit: started making headway on the machine again.
[23:00:45] <witnit> If you build a proper capacitor bank you might be able to get through your rapids without over drawing your main line
[23:00:51] <witnit> nice MacGalempsy
[23:01:05] <zeeshan> my mills motors are 2.4kW each
[23:01:06] <zeeshan> x 3
[23:01:26] <zeeshan> + 4kW spindle..
[23:01:32] <zeeshan> that machine is on a 100A breaker
[23:01:36] <witnit> glad to hear, I have made some more moves, just got new mesa cards in from JT-Shop
[23:01:40] <zeeshan> it doesnt really draw 100A tho
[23:02:40] <Loetmichel_> americans and their 110V-0-110V strange thing
[23:02:51] <Tom_L> hah
[23:03:11] <Loetmichel_> over here in german nearly every house has a 3 phase 63A main fuse
[23:03:30] <zeeshan> question for you guys
[23:03:34] <Loetmichel_> meaning 75kw maximum load
[23:04:02] <zeeshan> if you have a 20HP motor, that is supposed to draw 53A FLA
[23:04:07] <zeeshan> but you're only using 10hp of it
[23:04:14] <zeeshan> will it still draw 53A?
[23:04:15] <zeeshan> :/
[23:04:36] <Tom_L> half load?
[23:04:41] <zeeshan> ya
[23:04:45] <Loetmichel_> it will only draw 53A if loaded to the max
[23:04:47] <Tom_L> you should know that answer already
[23:04:57] <zeeshan> i'd think i'd drawing 53/2
[23:05:07] <Loetmichel_> not exactly
[23:05:38] <Loetmichel_> usually the motor itself has some inefficiencies
[23:05:56] <zeeshan> well im assuming its a linear relationship
[23:05:57] <Loetmichel_> calculate ~10% "headroom" for that
[23:06:17] <zeeshan> if you take a motor thats 1hp
[23:06:23] <zeeshan> and you stall it
[23:06:31] <zeeshan> it should be drawing out fla right?
[23:06:39] <zeeshan> but if you take a 20hp motor and you stall it
[23:06:41] <Loetmichel_> whats fla?
[23:06:45] <zeeshan> it'll want to draw 53 FLA?
[23:06:47] <zeeshan> full load amps
[23:06:51] <Loetmichel_> no
[23:07:03] <zeeshan> a/c motors confuse me :P
[23:07:09] <Loetmichel_> not if its a asynchronus three phase
[23:07:24] <Loetmichel_> once that stalls it will draw slightly UNDER FLA
[23:09:47] <zeeshan> http://ecmweb.com/mag/405ecm08fig1.jpg
[23:09:52] <XXCoder> hey all
[23:09:52] <R2E4> Did I see that joint-axes is merged? 2.7.7?
[23:09:52] <zeeshan> no idea which nema letter mine is :P
[23:09:58] <XXCoder> man not used to car driving :P
[23:10:02] <XXCoder> got too used to van
[23:11:58] <Loetmichel_> XXCoder: hrhr.. i drove a stick shift merc sprinter for the company lately... after driving automatic gearbox for years... took me a few km to "silence" the shifting ;)
[23:12:08] <XXCoder> lol
[23:12:23] <XXCoder> loet my van just decided to die :P
[23:12:25] <Tom_shop> http://kurz.com/wp-content/uploads/2014/09/Baldor-NEMA-Frame-Chart.pdf
[23:12:28] <Tom_shop> zee
[23:12:40] <MacGalempsy> https://flic.kr/p/NfeM7L
[23:12:48] <XXCoder> im sure its something minor but fuck it been repairing it so far, I'd have confused it with FORD (fix or repair daily)
[23:12:54] <MacGalempsy> spent the day printing away.
[23:12:57] * XXCoder now owns ford, ironic.
[23:13:54] <zeeshan> that doesnt tell you abcde!
[23:13:56] <Loetmichel_> XXCoder: i invested €3900 in a car that is worth less than 1800 earlier this year...
[23:14:14] <Loetmichel_> engine gaskets broke.
[23:14:16] <XXCoder> ow.
[23:14:16] <Loetmichel_> ALL of them
[23:14:29] <XXCoder> that is when having laser cnc is handy
[23:14:49] <Loetmichel_> the gasket set was cheap
[23:15:02] <XXCoder> ah yea labor
[23:15:46] <Loetmichel_> dismantling the 2,5 liter 6cylinder turbodiesel (including the whole front of the car up to the firewall) was not THAT cheap tho
[23:16:32] <Loetmichel_> it is so cramped under that hood that there is no way to get the engine out there without getting rid of the front wheels, steering AND the fenders
[23:16:47] <Tom_L> poor design
[23:17:08] * zeeshan just found on the internet
[23:17:12] <Loetmichel_> to big an engine into a to small motor compartment
[23:17:18] <zeeshan> that undersizing a vfd for an ac motor is okay
[23:17:32] <zeeshan> ac motors do need about 1/3-1/2 the fla rating to generate their mag field and spin
[23:17:48] <Loetmichel_> its an Opel Omega station wagon... with the BMW turbodiesel engine and gearbox
[23:17:57] <Loetmichel_> it barely fits in there
[23:18:56] <Loetmichel_> they even shrank (whats past of "shrink"?) the radiator
[23:19:33] <Loetmichel_> ... with the effect that the engine now lights the "too hot" lamp if you floor it more than 10 minutes continous
[23:20:39] <Loetmichel_> but anyways: i like that car or i wouldnt have paid 2 times its street worth in repairs
[23:20:58] <XXCoder> lol loet ever seen mecury sable 1988 big block v6?
[23:21:11] <XXCoder> theres 3 inches or less clearance around engine.
[23:21:25] <XXCoder> need anything fixed? lift engine
[23:21:37] <Loetmichel_> XXCoder: american cars tend to be a bit bigger
[23:21:41] <XXCoder> 3.8l in small car
[23:21:43] <Tom_L> just torch the fenderwells out
[23:21:44] <XXCoder> well yes.
[23:21:49] <Loetmichel_> and 3 inces is WAAAY room
[23:21:59] <XXCoder> but then mecury sable is midsize, and engine belongs to BIG truck.
[23:22:07] <Loetmichel_> i am happy if i can get my hand between the fenders and the block
[23:22:57] <zeeshan> https://www.motortong.com/model/96296/PC1-200.html
[23:23:00] <zeeshan> 2000 bux for the drive
[23:23:01] <zeeshan> jesus!
[23:23:42] <Loetmichel_> https://data.motor-talk.de/data/galleries/0/38/2317/40242964/haendler2-7566401499671804030.JPG <- any questions? (not my car, but same car, same engine)
[23:23:47] <Tom_L> better get a spare zee
[23:24:31] <XXCoder> pretty tight
[23:24:34] <zeeshan> honestly
[23:24:41] <zeeshan> im better off buying a name brand 40hp 3 phase vfd
[23:25:03] <XXCoder> Loetmichel_: http://www.ford-taurus.org/taurusinfo/Engine/Large/90-95_Essex.jpg
[23:25:03] <Loetmichel_> zeeshan: all VFDs i know can limit the current
[23:25:14] <zeeshan> yes
[23:25:14] <Loetmichel_> by some parameter
[23:25:16] <zeeshan> you're right
[23:25:18] <XXCoder> front is more roomy at 3 inches
[23:25:22] <zeeshan> both my eaton and sumitomo do that
[23:25:30] <zeeshan> but it'd be nice to just get the right size vfd.
[23:25:36] <Loetmichel_> so why dont use the machine as it is and simply limit the max current?
[23:26:13] <Loetmichel_> XXCoder: oh nice, mounted sideways
[23:26:14] <zeeshan> Loetmichel_: i gotta buy a drive anyway
[23:26:20] <zeeshan> so might as well buy something correct
[23:26:35] <Loetmichel_> zeeshan: be careful
[23:26:36] <XXCoder> loet the tank on left on mine had belt rub marks lol thats how close it is
[23:26:36] <XXCoder> tank was bit loose
[23:26:41] <zeeshan> ??
[23:27:05] <Loetmichel_> i have once driven a 11kw 3phase motor with a 3,5kW VFD
[23:27:19] <zeeshan> ive driven a 5hp motor with a 1hp drive
[23:27:19] <zeeshan> :D
[23:27:26] <Loetmichel_> it took a bit on parameter tewaking to get it running at all
[23:27:48] <zeeshan> https://www.driveswarehouse.com/sj700d-220lfuf3-1-3217
[23:27:48] <zeeshan> lol
[23:27:52] <zeeshan> its cheaper to buy the 40hp vfd
[23:28:02] <XXCoder> Loetmichel_: still miss mine. :( utterly reliable. owned it for over 9 years, getting close to 10 when idiot totaled it
[23:28:03] <Loetmichel_> it didnt like the "spin up" current of the big AC
[23:28:29] <Loetmichel_> XXCoder: recenty some idiot in a VW caddy reared me...
[23:28:42] <XXCoder> second one record is just 3 years.
[23:28:58] <Loetmichel_> his car was 8 inces shorter... mine had some scratches on the bumper ;)
[23:29:07] <XXCoder> lol
[23:29:32] <MacGalempsy> which
[23:29:35] <XXCoder> I was lucky that accient, to react rapidly to turn fatality to really bad headache
[23:29:41] <MacGalempsy> model is the caddy?
[23:30:15] <Loetmichel_> caddy is a "golf" with a pickup instead of the rear seats
[23:30:28] <Loetmichel_> Golf is rabbit in america i belive?
[23:30:40] <Loetmichel_> s/pickup/flatbed
[23:31:15] <MacGalempsy> yeah. just looked it up. not sure ive seen those before
[23:31:49] <R2E4> Have to load master to get the news joint-axes?
[23:32:50] <Loetmichel_> it was unfair tho
[23:33:04] <MacGalempsy> any luck with insurance on the damage?
[23:33:35] <Loetmichel_> the Omega is ~2 tons of steel. and the back bumper is not meant to crumple to take away engergy
[23:33:42] <Loetmichel_> as the front of any modern car is
[23:34:17] <XXCoder> loet yeah I check my newish car (2012)
[23:34:18] <Loetmichel_> i didnt need insurance. not much done to my car aside from some scraches
[23:34:34] <XXCoder> it has crumble support bars for front
[23:34:41] <XXCoder> interesting structure
[23:36:06] * Loetmichel_ was standing on a roundabout waiting to get in... foot on the brakes
[23:36:39] <Loetmichel_> the caddy thought i would use that space ahead and accelerated... i didnt thought i would fit so i stood on the brakes...
[23:36:45] <Loetmichel_> *bang*
[23:36:54] <Loetmichel_> didnt even feel the car shaking ;)
[23:37:02] <XXCoder> olviously not defensive driver.
[23:37:04] <MacGalempsy> ha!
[23:38:00] <Loetmichel_> bad thing was that the caddy was a brandnew company car... and the driver was on his first day... ;)
[23:38:13] <Loetmichel_> for that company
[23:38:45] <XXCoder> doh
[23:38:49] <MacGalempsy> ouch.
[23:38:50] <Loetmichel_> i think it was also his last day.
[23:39:34] <XXCoder> my bro was driving 1975 mushung, other guy rear hit my bro's car. bumper was crooked. other car was totaled.
[23:39:54] <XXCoder> and funny thing car was in that guy name for few days only
[23:40:42] <Loetmichel_> result on the caddy was: totally mashed grill, both headlights shattered, front bumper disappeared into the engine, hood rolled up a good 2" like a tin can
[23:41:05] <Loetmichel_> coolant and steering fluid was leaking
[23:42:18] <Loetmichel_> and on my Omega it was some barely visible cracks in the paint of the bumper and a "fallen in" Ultrasonic transducer for the PDC
[23:43:06] <MacGalempsy> pdc?
[23:43:18] <Loetmichel_> park distance control
[23:43:26] <MacGalempsy> ah
[23:45:13] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=12135&g2_imageViewsIndex=1 <- you can barely see one of the sensor pressd in a little
[23:45:29] <Loetmichel_> and some shadows where the paint on the bumper cracked
[23:45:58] <Loetmichel_> the bumper is plastic so it snapped back to the intended shape after the caddy backed up
[23:46:03] <XXCoder> loet I can see car lines not quite line up now
[23:46:08] <XXCoder> so its slightly deformed
[23:46:13] <XXCoder> but hardly visiable
[23:47:10] <Loetmichel_> you mean the silver trim on the sides?
[23:47:18] <Loetmichel_> they were simply mounted that way ;)
[23:47:30] <XXCoder> nah the hatch
[23:47:42] <XXCoder> bumper too
[23:47:54] <Loetmichel_> the hatch was never touched
[23:47:57] <XXCoder> its off by maybe a mm or 2 at most
[23:48:10] <XXCoder> like I said its hardly visible
[23:48:43] <Loetmichel_> the car is from 2003... so i didnt care about a few more scratches/dents ;)
[23:49:01] <XXCoder> indeed
[23:49:22] <Loetmichel_> and the transducer was easily enough fished out the foam inside the bumper and replaced into the slot ;)
[23:49:56] <XXCoder> that mecury sable I menioned? it was quite ugly
[23:50:15] <Loetmichel_> it being an Opel(GM!) i still cant belive it isnt rusting til now... being 13+ years old...
[23:50:54] <Loetmichel_> usually you could touch the street whit closed doors sitting on the drivers seat on an opel after 10 years
[23:51:31] <Loetmichel_> and its dirt cheak to buy used in germany
[23:51:43] <Loetmichel_> seems the ppl here dont want "big" cars any more
[23:51:51] <Loetmichel_> cheap
[23:52:34] <Loetmichel_> sadly Opel discontinued the Omega in 2003
[23:53:01] <Loetmichel_> it was the last station wagon with THAT kind of loading capacity that you could buy here.
[23:53:30] <Loetmichel_> the newer cars are all smaller and/or unreasonably expensive.
[23:54:44] <Loetmichel_> that thing can load a 160*205*85cm box that weights 1.2 metric tons
[23:54:55] <Jymmm> lowridah:Question... Did you pump water from or to the pool?
[23:55:02] <Loetmichel_> ... and still lock in the cruise control at 140 mph ;)
[23:55:10] <Jymmm> bah Loetmichel_ ^^^
[23:55:39] <Loetmichel_> Jymmm: as the pump is a submersible...
[23:56:11] <Loetmichel_> it pumped water from the pool thru the copper spiral and back into the pool
[23:56:28] <Jymmm> Loetmichel_: ty
[23:56:33] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=12271&g2_imageViewsIndex=1
[23:56:42] <Loetmichel_> http://www.cyrom.org/palbum/main.php?g2_itemId=12274&g2_imageViewsIndex=1
[23:56:54] <Loetmichel_> the gray pump outside is the filter
[23:57:03] <Loetmichel_> it has nothing to do with the heating ;)
[23:57:14] <Jymmm> Loetmichel_: I understand
[23:57:42] <Jymmm> Loetmichel_: I didnt think that pump could deal with "hot" water, but I was just dbl checking
[23:58:47] <Loetmichel_> Jymmm: it could deal with 31°c water
[23:59:01] <Loetmichel_> but i doubt it would survive boiling water
