[00:11:18] <pink_vampire> hi
[00:11:46] <pink_vampire> cradek: alex_joni seb_kuzminsky ?
[00:12:36] <XXCoder> hey pink_vampire
[00:12:41] <pink_vampire> hi XXCoder
[00:13:51] <pink_vampire> I know It's not going to make any difference for you, but I want to make a teamspeak server for out cnc comunity
[00:19:26] <XXCoder> cool
[00:20:24] <pink_vampire> https://www.youtube.com/watch?v=9huUsYDJZrM
[00:20:34] <pink_vampire> this is amazing
[00:26:27] <XXCoder> yeah
[00:26:38] <XXCoder> there is severial "easy" to make lasers
[01:05:42] <trentster> pink_vampire: teamspeak - thats pretty awesome!
[01:06:26] <XXCoder> I bet it is.
[01:20:26] <pink_vampire> trentster: I know, I like it, and I'm use it alot.
[01:21:22] <XXCoder> I remember one time you had live video of machine running
[01:25:55] <pink_vampire> yes, I was really fun.
[01:26:07] <pink_vampire> I ned to finish the panel..
[01:26:19] <pink_vampire> now I'm not even home :(
[01:26:41] <pink_vampire> did you finish with youre machine?
[01:36:49] <chupacabra> what is the best free engraving program. no more than .005
[01:37:27] <chupacabra> diamond tip
[01:43:04] <archivist> chupacabra, the tool size is not really relevant to your software
[01:43:34] <archivist> what are you really trying to do with what machine
[01:55:35] <trentster> XXCoder: I am busy uploading a 25 minute long Vectric / LinuxCNC tutorial to Youtube, does youtube handle the captioning automagically via voice recognition?
[01:56:27] <XXCoder> trentster: yes, though i suggest do quick correction
[01:56:38] <XXCoder> fix some errorous words
[01:56:53] <XXCoder> if its pretty accurate it should be few minutes
[01:56:56] <pink_vampire> trentster: do you have a youtube channle?
[01:57:18] <XXCoder> trentster: I dont worry about word for word perfect translationb
[01:57:27] <XXCoder> just basically what you are saying
[01:57:46] <trentster> it probably is not optimised for non US accents, so error rate will be higher I guess.
[01:58:09] <XXCoder> yeah try and see
[01:58:15] <trentster> pink_vampire: yeah but its mainly technology videos there, this is the first CNC related one I have done
[01:58:23] <pink_vampire> link?
[01:58:44] <trentster> the video is not up yet its still uploading its 2.7GB in size
[01:59:05] <pink_vampire> I mean to your channel
[01:59:58] <pink_vampire> trentster: ^
[02:03:12] <pink_vampire> chupacabra: for 2d or 3d?
[02:04:32] <pink_vampire> chupacabra: and also what is your cad program?
[02:04:59] <trentster> pink_vampire: https://www.youtube.com/channel/UCzqIbFebRrDwfW46BAN26Uw
[02:07:42] <pink_vampire> a lot of cloud stuff
[02:07:46] <pink_vampire> trentster: ^
[02:09:12] <trentster> yup - a lot of cloud stuff
[02:14:11] <XXCoder> I see your cnc is making 3d profile of animal
[02:16:21] <trentster> aah yeah thats an old one, was test carving something
[02:16:26] <XXCoder> yeah
[02:16:38] <XXCoder> looks cool, want to make stuff like that evenually.
[02:17:30] <trentster> I dont even have that spindle anymore - that was a 400W spindle - its since been upgraded to a 2.2Kw
[02:18:03] <XXCoder> lol ok.
[02:18:08] <XXCoder> still uploading?
[02:18:59] <trentster> you will probably like the video tutorial I am uploading then, it also features 3D Art Peice object creation and 3D carving. I also included some lessons learned.
[02:19:13] <XXCoder> nice
[02:19:20] <trentster> Just takes so darn long to upload when rest of the family is Netflixing!
[02:24:56] <trentster> Deejay: Moin
[02:25:05] <trentster> ;-) beat you to it
[02:25:30] <Deejay> moin
[02:25:59] <trentster> XXCoder: I am sure a ton of folks outsource the captioning to a "mechanical Turk" type service - probably costs a couple of cents per minute for professional human captioning services
[02:26:32] <XXCoder> yeah some cheat and download autocaptions and send it to you as "english"
[02:26:44] <XXCoder> I had let few people know that
[02:26:59] <XXCoder> there is fewe services that you can use lemme get links
[02:28:21] <trentster> XXCoder: here is a company that leverages mechanical turk and charge per minute https://www.speechpad.com/
[02:28:40] <trentster> they must make a ton of money as mech turk is really cheap
[02:28:45] <XXCoder> interesting
[02:29:03] <XXCoder> http://nomorecraptions.com/
[02:29:06] <XXCoder> this is for yourself
[02:29:25] <XXCoder> free
[02:30:25] <XXCoder> other way, also free http://www.amara.org/en/
[02:30:56] <XXCoder> earlier one you dont even need to make an account
[02:31:52] <trentster> cool thanks, I have bookmarked both of them
[02:32:07] <trentster> I guess I should get in the habit of doing this for all videos
[02:34:16] <trentster> accessibility shouldn't be an after thought.
[02:35:18] <XXCoder> yeah
[02:35:27] <XXCoder> its not only accessability though
[02:35:36] <XXCoder> 80% of captions users arent deaf.
[02:35:41] <XXCoder> 80%.
[02:37:04] <trentster> yeah, its great for SEO as well
[02:37:13] <trentster> and indexing of information
[02:37:14] <XXCoder> many reasons but yeah
[02:42:51] <archivist> subtle difference between SEO and search engine spam :)
[04:23:59] <trentster> XXCoder: video is up - but captioning still needs to be done: https://www.youtube.com/watch?v=swa-eX0irPg
[04:24:06] <XXCoder> looking
[04:24:38] <XXCoder> guess it takes time for voice translation to appear
[04:24:50] <XXCoder> that or you have to go somewhere and set it? dunno
[04:25:34] <trentster> probably takes some time
[04:25:43] <trentster> bbl - dinner time
[04:26:49] <XXCoder> em to do buolk removal then ballnose em
[04:26:50] <XXCoder> nice
[04:27:01] <XXCoder> erm maybe facemill on left too?
[04:29:38] <XXCoder> dang
[04:29:40] <XXCoder> you has auto z
[04:29:45] <XXCoder> I need that lol
[04:32:29] <CaptHindsight> http://thenextweb.com/shareables/2016/01/25/this-robot-can-solve-a-rubiks-cube-in-1-second/ should have placed it in water to make it even faster and keep the joints from melting
[04:33:40] <XXCoder> CaptHindsight: or coolant asprayer heh
[04:34:43] <XXCoder> CaptHindsight: can it solve 22x22 cube? ;)
[04:35:17] <CaptHindsight> I get the standard off the shelf cube as a standard
[04:35:52] <XXCoder> that is fast,.
[04:35:54] <CaptHindsight> otherwise you could machine something that could handle more stress and have less friction on the joints
[04:36:13] <XXCoder> 22x22 can barely be handled by people. very frigile
[04:36:21] <Hawku> solve 22x22 cube like this: https://youtu.be/i84PRVPieeU?t=1h34m42s ?
[04:36:30] <XXCoder> guy who made it had to rebuild it few times, replacing parts few times I think
[04:36:46] <XXCoder> Hawku: sorry I was faster lol
[04:37:24] <XXCoder> https://www.youtube.com/watch?feature=player_embedded&v=qlnUEknwdcI more easily usable
[04:42:58] <XXCoder> 7:32 time to complete. insane
[04:43:06] <XXCoder> it would take me years
[05:18:18] <gonzo_> does the computer know about pealing the stickers off though?
[05:18:47] <XXCoder> heh 1 second? peeling one sticker off cleanly takes more time.
[05:19:20] <MrSunshine> hmm two wire sytem to hold the machine square compared to one, same length of cables BUT each part of the two wire has half the length, would that help with stiffness of the wire? =)
[05:20:08] <archivist> something solid is stiffer than wire
[05:22:02] <MrSunshine> http://postimg.org/image/pst1taf6x/
[05:22:13] <MrSunshine> archivist: yes but due to structure i cant have anything solid =)
[05:22:24] <MrSunshine> the right one is how i do it now, the left one is what im thinking of =)
[05:22:39] <trentster> XXCoder: yeah auto z and proximity sensors are the most useful things by far on the machine
[05:22:49] <XXCoder> nice
[05:23:20] <MrSunshine> from what i can tell the cable even tho its tensioned quite a bit flexes quite alot over the like 7 meters of wire that is there now .. continious wire
[05:24:14] <trentster> you can make auto z out of anything, I use a magnet latch to click onto spindle, which makes it effortless to use
[05:24:53] <XXCoder> guess it uses pin
[05:25:08] <MrSunshine> gonna make stiffeners for the ballscrew holder plates today to get that flex go away atleast =)
[06:35:46] <mase-tech> hi peps, i want to build a cnc machine with linux cnc
[06:35:57] <mase-tech> quiet nice.. yes i know :d
[06:36:21] <XXCoder> there is so mny ways to do it
[06:36:28] <mase-tech> i want to use linux cnc installed on a linux pc which i have.
[06:36:59] <mase-tech> so i think i must start with the hardware
[06:37:18] <XXCoder> what you planning to make?
[06:37:35] <mase-tech> which hardware do i need to controll the motor drivers from pc ?
[06:37:45] <XXCoder> also few different ways
[06:37:54] <XXCoder> theres mesa, cheap chinese controllers
[06:38:04] <mase-tech> it is more like i want to learn and develop me and the machine i use
[06:38:05] <XXCoder> there is few ways using arduino
[06:38:25] <XXCoder> for example arudino is fine for small machine for simple things
[06:38:28] <XXCoder> but not for big machine
[06:38:43] <mase-tech> i already build such a machine
[06:38:51] <mase-tech> i have a raspberry pi
[06:39:00] <mase-tech> and used the gpios
[06:39:34] <mase-tech> work fine. can linux cnc control the arduino ?
[06:39:53] <XXCoder> yeah but arudino is not very suitable for cnc reallt
[06:40:02] <XXCoder> again, depends on what you need to do
[06:40:12] <mase-tech> i want to use a old pc with linux working with linux cnc
[06:41:37] <mase-tech> why is arduino not very suitable? because it control the motor driver
[06:41:58] <Tom_itx> linuxcnc does a better job at that
[06:42:03] <XXCoder> if you need more powerful machine to cut metal
[06:42:13] <XXCoder> arudino just cant do it
[06:42:22] <XXCoder> though there is ways using drivers
[06:44:21] <mase-tech> i really believe u, could u explain why arduino is not suitable. because it only controls the motor driver. and the motor driver supplies the motor with "high" current needed
[06:44:48] <XXCoder> honestly? I would prefer a suitable pc with linuxcnc to do it
[06:44:56] <XXCoder> basically any reasonable pc would work
[06:44:59] <XXCoder> but not too new
[06:45:03] <XXCoder> or old
[06:45:04] <Tom_itx> with linuxcnc and mesa cards you can get higher steprates etc and better performance
[06:45:23] <XXCoder> Tom_itx: and better compution power for pathway prediction
[06:45:26] <XXCoder> less pauses
[06:45:37] <archivist> mase-tech, you only have to pass the same infor from linuxcnc to the drivers, the arrrrguino has nothing to do
[06:46:17] <archivist> just use a cheap BOB off ebay for opto isolation
[06:47:03] <mase-tech> thx tom and coder. good arguments
[06:47:13] <archivist> eg http://www.ebay.co.uk/itm/321905519866
[06:48:18] <mase-tech> nice
[06:49:06] <mase-tech> which ports do i use ? the parallel port ?
[06:49:08] <mase-tech> or usb ?
[06:49:35] <Tom_itx> not usb
[06:49:38] <archivist> parallel the usb cable is just a 5v supply
[06:49:42] <Tom_itx> it's not 'realtime' enough
[06:50:07] <mase-tech> ok got it
[06:52:22] <mase-tech> this is cool stuff
[06:54:14] <mase-tech> so when i connect the controller will linux see what is connected ? or does linux cnc use paralell port
[07:05:14] <Tom_itx> there are config files for that
[07:05:29] <mase-tech> ok i am searching tuts
[07:05:51] <mase-tech> i am working on it
[07:06:19] <Tom_itx> http://linuxcnc.org/docs/2.7/html/
[07:08:08] <archivist> linuxcnc requires some configuration
[07:15:06] <mase-tech> i love it :)
[07:15:23] <archivist> that is a good start
[07:15:48] <mase-tech> and thx
[07:16:28] <mase-tech> and by the way. Thx for this software. much appriciated
[07:16:37] <mase-tech> free and open
[07:16:43] <mase-tech> even more love :D
[07:36:24] <jthornton> 55 down 10 to go
[07:41:22] <archivist> BP in production?
[08:18:33] <JT-Shop> pounds lol
[08:19:03] <JT-Shop> well it could be the number of times I've rewired the BP
[08:19:14] <archivist> ah, getting rid of the fatberg
[08:24:17] <JT-Shop> aye, been working on that for a year or more
[08:25:31] <JT-Shop> my target is 12.5 stone
[08:25:57] <JT-Shop> so today I'm 13.214285714 stone
[09:06:17] <JT-Shop> that didn't take long to bend my first probe tip :(
[09:06:41] <archivist> ouch
[09:07:31] <archivist> must approach slowly
[09:11:10] <JT-Shop> selector in wrong position
[09:11:22] <JT-Shop> went down instead of left
[09:14:17] <archivist> but the contact brake should have stopped the machine before bending
[09:14:23] <archivist> break
[09:15:05] <JT-Shop> quite possibly if I wasn't using the MPG
[09:16:39] <archivist> I think we need a new hal input for probing where it is a stop because unexpected touch rather than estop
[09:17:40] <archivist> I am reading/playing with my cmm and how the Makino does probing
[09:17:53] <JT-Shop> I get a probe tripped during a jog but the jog does not stop
[09:18:49] <archivist> with my cmm you have to restart and jog off the item
[09:19:07] <archivist> not an estop error though
[09:20:17] <pcw_home> estop is not good on many servo systems as they will coast
[09:22:18] <pcw_home> you probably want a controlled stop at max accel (does setting the feed rate/rapidrate to 0 do this? )
[09:23:40] <archivist> yup I agree, system needs an oh bugger controlled stop
[09:26:33] <Sync> most of them will open the dc link and short one set of the driver fets
[09:26:58] <Sync> as that is a safe mode of operation for motors
[09:27:43] <archivist> a concept the cmm has, it arms(enables) the probe which lights the probe led and when jogging will immediately stop on a touch
[09:27:47] <Sync> but that depends on the safety level your inverter is capable of
[09:29:29] <ReadError> hey quick question, if i am not using RTAI (need the rtnet stuff), can I go w/ x86_64 ?
[09:35:58] <ReadError> ahh looks like preempt-rt works with amd64 on wheezy
[09:36:51] <MarkusBec> 64bit is not a problem
[09:42:44] <ReadError> MarkusBec yea seems its just for RTAI-5 having issues
[09:57:20] <MrSunshine> what to do when datasheet of the stepper driver does not state the hold times etc for the logic levels ?
[09:57:37] <JT-Shop> start large
[09:57:40] <pcw_home> use 20 usec
[09:58:48] <pcw_home> setup and hold times have very little impact on performance so there is really no cost associated with making them large
[10:00:28] <pcw_home> also step time/space time should be as large as you maximum step rate will allow
[10:00:30] <pcw_home> (dont use manufacturers minimums, these are on the edge of not working)
[10:00:41] <MrSunshine> and it states 300khz step frequency, so for step len and space there?
[10:01:30] <ssi> morn
[10:06:13] <MrSunshine> but at 300khz then, would that be 1.6 step time and 1.6 step space ?
[10:15:34] <maxcnc> Hi from a sunny Day in Germany
[10:21:15] <CaptHindsight> ReadError: what is wrong with RTAI-5?
[10:25:13] <miss0r> New mill up and running. Thank you guys ;)
[10:25:44] <archivist> already!!
[10:25:59] <miss0r> What do you mean already?
[10:26:16] <miss0r> it took two days :)
[10:26:30] <archivist> most seem to take weeks :)
[10:26:45] <miss0r> with my first mill it took forever.
[10:26:49] <miss0r> :)
[10:26:50] <maxcnc> miss0r: hommade or retro
[10:27:06] <miss0r> maxcnc: neither.
[10:27:32] <maxcnc> is there a third option
[10:27:37] <miss0r> at the moment it is still manual. Will probaly continue to be so for a while. It is there to prepare the raw material for the CNC
[10:28:26] <miss0r> I assumed you meant retro-fitted? (as in supplied with steppers'n such)
[10:31:18] <miss0r> archivist: Today I ordered two tapers for it. It turns out it is DIN2080 SK40 it uses. (I brought the insert I already had with me to the local tool pusher). One with a ER32 collect chunk and a collect set (18 peices) and one that can accomidate my 80mm indexable endmill. Will come later this week - can't wait
[10:32:10] <miss0r> and I got it for a steal; ~150USD
[10:36:50] <maxcnc> im off AFK
[10:37:25] <archivist> manual is very useful for one off jobs
[10:39:02] <miss0r> I don't presume anyone in here is into classic computers? I am giving away my old HP 2640A terminal. that or it will hit the trash(which i'm not happy about)
[10:39:42] <archivist> there are a couple sort of
[10:40:06] <archivist> I have some parts from a dead one
[10:40:26] <archivist> it had an 8008
[10:40:28] <miss0r> hehe this is a '74 terminal. so I guess not many are left
[10:40:51] <archivist> so really wants to be saved
[10:41:21] <miss0r> archivist: I love old/classic computers. My favorite is a 80286 desktop I have. :)
[10:41:45] <miss0r> not as old as 8008 ofc. but it is of an age that allows it to be used still :) for... stuff
[10:42:54] <archivist> miss0r, http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=6085&subject=22872
[10:44:17] <archivist> it is the only place I have seen an 8008 in use
[10:44:43] <miss0r> would be to 'geeky' of me to call it pretty? :)
[10:45:38] <archivist> all I have left is some of the PCBs from the 2640
[10:46:02] <miss0r> you can have mine if you want? :)
[10:46:24] <archivist> cannot afford the carriage
[10:46:48] <miss0r> located? US?
[10:47:07] <archivist> UK
[10:47:26] <miss0r> meh... Let me calculate the shipping for you. then make up your mind
[10:47:44] <archivist> I have no proper job at the moment
[10:49:28] <miss0r> its about 44uk pounds it seems
[10:49:35] <miss0r> alright. Just wanted to offer.
[10:49:47] <archivist> I am not sure if my boards came out of one the computer/calculators of the period,
[10:50:25] <miss0r> well. the CPU is released in 1972. and the terminal is from '74 - so it is likely
[10:50:34] <miss0r> /possible
[10:51:07] <archivist> they did use bits from other systems in odd places
[10:52:04] <archivist> must be a collector near you
[10:52:49] <miss0r> hard to find another one like me in Denmark. Too small'a contry to hold more than one of each(in too many cases)
[10:53:12] <enleth> the original control of my bridgeport is based on 8085
[10:53:27] <enleth> it's a bit of a weirdo
[10:53:37] <miss0r> indestructable controller :)
[10:54:17] <miss0r> I am building one based on a '286 to digest g-code. :)
[10:55:08] <enleth> 8085 is basically a 8080 redesigned to compete with Z80, which was designed to compete with the original 8080
[10:55:12] <miss0r> err... it is still labeled 'work in progress' in my head. but the sad truth be told, since I became a father in December, things have not moved along so fast :)
[10:56:37] <miss0r> enleth: do you have a pic' of the controller?
[10:57:29] <enleth> miss0r: outside - google Heidenhain TNC 131
[10:57:32] <enleth> inside - not yet
[10:58:02] <enleth> I did open it a few times to debug some intermittent electrical problems, but no photos were made
[10:58:04] <miss0r> looks rugged :)
[10:58:26] <enleth> it's a sandwich of 4 PCBs that take up the whole area behind the front panel
[10:58:29] <enleth> all 2-sided
[10:58:38] <enleth> no labels, no component names, nothing
[10:58:43] <enleth> traces look hand painted
[10:58:50] <miss0r> nice
[10:59:17] <enleth> about 50% of that is a giant I/O expander for the 8085, it doesn't have enough GPIO to handle the machine on its own
[10:59:28] <enleth> mostly 74 series chips
[11:00:42] <miss0r> how capable is the tnc 131 controller?
[11:00:50] <miss0r> (what can you do with it)
[11:00:58] <enleth> it isn't
[11:01:11] <enleth> it's a point-to-point MDI control
[11:01:21] <miss0r> so only linear?
[11:01:45] <enleth> and mine can't even do diagonals because there's just one servo drive that's switched between motors
[11:02:05] <miss0r> heh. alright. so basically you use it for position readouts?
[11:02:16] <enleth> supposedly there is a version of TNC 131 that can interface with 3 drives and produce diagonals, but not arcs
[11:02:25] <archivist> or a cnc self act
[11:02:25] <enleth> mine doesn't, thouugh
[11:02:27] <enleth> *though
[11:02:39] <enleth> basically, yes
[11:02:55] <enleth> the mill is a cnc/manual hybrid so it's still useful
[11:03:47] <CaptHindsight> just think, if M$ and IBM had chosen Zilog we'd all be using the Z80,000,000 right now :P
[11:03:54] <enleth> and I'm thinking of keeping it in parallel to mesa
[11:04:19] <enleth> (which I'm still waiting for, cleared the customs but it's stuck somewhere between customs and local postal service)
[11:04:42] <miss0r> indeed. sometime in the future I am thinking it could be a good idea to retrofit the FNK 25A with some cnc controller. But this time around I am hoping I can find a plug'n'play kit. that is not too expensive that is :)
[11:06:34] <miss0r> But I first need to see the machine realy perform before I spend too much money on it
[11:15:22] <anomynous> used machining center? ;D
[11:30:47] <CaptHindsight> http://www.ebay.com/itm/Bridgeport-Series-I-R2E3-CNC-Mill-Lots-of-extras-included/301849216331 "free loading" vs freeloading
[11:36:46] <FloppyDisk5_25> that's a good deal. too far away.
[11:37:02] <archivist> go fetch
[11:37:27] <archivist> it is easy to spend other peoples money :)
[11:43:42] <Simonious> Yeah!
[11:47:08] <tcurdt> sorry for the OT question but where should I go for CNC chit chat?
[11:47:24] <tcurdt> I am thinking of building one
[11:47:56] <CaptHindsight> chit about CNC all you want in here
[11:48:25] <jdh> you should
[11:48:46] <tcurdt> CaptHindsight even questions about mechanical and electronic parts?
[11:48:59] <kengu> i was actually thinking of building one of these, http://www.thingiverse.com/thing:724999
[11:49:09] <CaptHindsight> if it involves a *dunio however you might be better served in another channel
[11:49:42] <CaptHindsight> tcurdt: sure
[11:50:04] <archivist> tcurdt, a few have self built machines
[11:50:14] <tcurdt> cool ... thx! I'll come back with my notes then :)
[11:50:14] <enleth> tcurdt: that's actually a hotter topic here than linuxcnc in particular
[11:50:27] <archivist> but of course in here we use linuxcnc to control them :)
[11:51:09] <CaptHindsight> http://thingiverse-production-new.s3.amazonaws.com/renders/be/49/c8/5c/23/Melvin_CNC_preview_featured.JPG tubing vs rods!?
[11:52:13] <CaptHindsight> must be for ease of cutting to length before filling with resin and sand
[11:52:30] <archivist> nah just pure cheapness
[11:53:06] <archivist> bet its the crappy welded seam type too
[11:53:45] <CaptHindsight> no cheapness was spared in the design of the toy
[11:54:17] <enleth> heh, designed almost like the 3D printer I never had the money to build
[11:54:43] <CaptHindsight> a penny saved is a penny not wasted
[11:54:54] <enleth> I mean, with the symmetric axes
[11:55:28] <enleth> or how would you call the fact that they have ~identical inertia and friction
[11:55:30] <kengu> CaptHindsight: I was thinking of making a vinyl cutter or led laser engraver with that design
[11:55:44] <enleth> that design should work nice for a fast 3D printer
[11:55:46] <archivist> you could lighten that design with balsa wood
[11:55:57] <enleth> but that render suggests milling
[11:56:02] <enleth> which is completely missing the point
[11:56:12] <CaptHindsight> anyone care to argue that it's impossible to be perfectly symmetrical similar to how everything is a spring?
[11:56:44] <enleth> CaptHindsight: that argument can be cut short easily
[11:56:51] <enleth> "yeah, you are right. so?"
[11:56:58] <CaptHindsight> no it can't :0
[11:57:00] <archivist> compared to the 1/8" bar he first used it is rigid
[11:57:04] <CaptHindsight> maybe I'm wrong
[11:57:33] <enleth> it's not a question of whether you can get a perfectly symmetrical design
[11:57:51] <enleth> it's a question of getting it "good enough" by going in that direction
[11:58:07] <archivist> dunno how you keep finding these amusing designs
[11:58:15] <CaptHindsight> everybody get you orders in from China ASAP it's almost the Spring Festival there
[11:58:23] <CaptHindsight> you/your
[11:58:48] <archivist> I ordered a BOB a few days ago...still waiting
[11:59:02] <enleth> I wonder if there are any chinese suppliers of stuff who *do* work during the festival in hopes of getting additional income
[11:59:31] <CaptHindsight> few, it's actually the one big break in the year for everyone
[11:59:40] <CaptHindsight> trains are jammed
[11:59:55] <CaptHindsight> tourist locations are near empty
[12:00:30] <CaptHindsight> the higher up you are the earlier you take off
[12:00:38] * JT-Shop has no idea where the D510 motherboard is now
[12:00:55] <CaptHindsight> just about everyone up top is already gone
[12:02:37] <Jymmm> (I can't remember who has a Ford Expedition / F150 in here)
[12:03:27] <Jymmm> CaptHindsight: Are they on their way to Miami for Spring Break?
[12:04:31] <CaptHindsight> Chinese spring break is spent getting drunk at home with family
[12:05:35] <Jymmm> not much different than here
[12:05:48] <ReadError> hmmm
[12:06:03] <ReadError> for RTnet, I need RTAI?
[12:06:23] <ReadError> I thought I read for the mesa ethernet stuff something about using userspace
[12:06:59] <JT-Shop> well crumb the D510 uses DDR2 and the Gigabyte uses DDR3 so I assume that won't work
[12:10:08] <JT-Shop> what does SS/DS mean on a memory spec sheet?
[12:10:22] <JT-Shop> single side double side?
[12:11:12] <cradek> I think so
[12:11:22] <JT-Shop> thanks
[12:12:02] <MrSunshine> http://postimg.org/gallery/2zc6fix38/160809ee/ fast update of the holders for the brackets =) from 0.1 - 0.2mm of flex at the indicator location to 0.01 to 0.02mm ...
[12:17:53] <FloppyDisk5_25> ?? userspace won't work w/ DDR3?
[12:20:58] <JT-Shop> are you asking or saying?
[12:21:38] <FloppyDisk5_25> Sorry - I'm asking. I don't get the inner workings of that conversatio - sorry.
[12:22:23] <FloppyDisk5_25> I'm inferring you want to talk to the mesa ethernet card. I only recall (maybe incorrectly) that you need preempt, but not sure.
[12:23:03] <FloppyDisk5_25> I read the writeup by Charles S. on the different Real time kernels, hurt my head, but was interesting.
[12:23:12] <ReadError> well thats why im confused
[12:23:16] <FloppyDisk5_25> :-)
[12:23:19] <ReadError> rtnet is for RTAI kernel
[12:23:22] <ReadError> apparently
[12:23:59] <ReadError> but I read somewhere else that you use the userspace build and preempt
[12:24:19] <FloppyDisk5_25> I recall something like that as well, but don't quote me..
[12:25:21] <FloppyDisk5_25> This talks about uspace and prempt. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Uspace
[12:25:23] <ReadError> yea im just lookin for the right way ;)
[12:27:32] <FloppyDisk5_25> looks like that link is what you might want, will take some work to make it work.
[12:27:33] <PCW> Yeah for our Ethernet stuff: uspace+Preempt-RT
[12:27:51] <ReadError> so no need for rtnet anymore?
[12:28:17] <PCW> we started wit RTNet
[12:28:22] <PCW> with
[12:31:11] <ReadError> alright so uspace + linux-image-rt-amd64 and im in business
[12:31:27] <PCW> but its lack of current drivers and general awkwardness made
[12:31:29] <PCW> us try Preempt-RT and a stock network stack( we thought as a temporary test platform )
[12:31:30] <PCW> But it works well enough that we never went back
[12:33:03] <PCW> you can also build your own Preempt-RT kernel ( much easier than building RTAI kernels )
[12:33:04] <PCW> This may be needed if you have modern hardware (<1 or 2 years)
[12:33:50] <ReadError> yea im using a new-ish j1900 board
[12:54:50] <maxcnc> hi ;-)
[13:19:23] <zhivko> I have microstepping on stepper set to 800 pulses per rev - so my calculation is as follows: 800 steps / (360 deg/8 ratio of small to big gearing couple) = 17.77778 steps / degree
[13:19:37] <zhivko> then I restart linuxcnc and give mdi command: G1 A10 F200
[13:19:45] <zhivko> And stepper that will drive small gear starts turning like a snail... For my feeling its just too slow for feed rate 200 degree/minute
[13:20:18] <zhivko> I use SCALE = 17.77778 for angular axis configuration
[13:21:01] <zhivko> Is anybody seeing what I am missing here ?
[13:21:35] <maxcnc> its in deg/sec
[13:22:16] <maxcnc> so you got 17steps per deg
[13:22:33] <zhivko> Why ?
[13:22:42] <zhivko> isn for linear is mm/min
[13:22:42] <maxcnc> can you upload thei ini to pastebin
[13:22:55] <maxcnc> mm/sec
[13:22:56] <zhivko> Why would for angular be per sec ?
[13:23:24] <maxcnc> if you enter 80 you get 4800mm/minb
[13:23:35] <maxcnc> 80mm/sec
[13:23:45] <maxcnc> velocity
[13:24:32] <maxcnc> the acceleration is in mm/sec²
[13:24:56] <zhivko> will paste - just a sec...
[13:26:29] <zhivko> http://pastebin.com/kd09nz8E
[13:26:57] <zhivko> see: [AXIS_3]
[13:28:24] <zhivko> Why would linear speed be in mm/min and angular in degree/sec ?
[13:28:53] <zhivko> Is there a logical explanation - it is true that I havent set time units anywhere in ini
[13:29:12] <maxcnc> what version are you on 2.7
[13:29:16] <zhivko> So why sometimes per min and in case of angular per sec ?
[13:29:27] <maxcnc> no its all in /sec
[13:29:56] <zhivko> so also linear feed rate when issuing MDI command is in mm/sec ?
[13:30:17] <maxcnc> no in the INI
[13:30:25] <maxcnc> in MDi its in mm7min
[13:30:25] <zhivko> maxcnc: I am using machinekig - but sssshhhhh please don't panic :)
[13:31:04] <maxcnc> the Real working is as you work with mm/min
[13:31:18] <maxcnc> the mashine setup is all in /sec
[13:31:54] <zhivko> So in ini velocities are in units per second
[13:32:07] <zhivko> In mdi command feed rates are in units per minute ?
[13:32:13] <zhivko> have I got that correct ?
[13:32:26] <maxcnc> yes
[13:32:43] <maxcnc> but your mashine is setup to go24000mm/min
[13:33:26] <maxcnc> this is not a setup from stepconf wizzard
[13:33:38] <zhivko> Yes - so actually 400.0 * 60
[13:33:45] <maxcnc> yes
[13:33:48] <zhivko> Yes - so actually 400.0 * 60 [deg/min]
[13:34:27] <zhivko> And difference between: MAX_VELOCITY and STEPGEN_MAX_VEL ?
[13:34:44] <zhivko> is it ok to have this values jut the same ?
[13:34:47] <maxcnc> the calculation internal
[13:34:50] <zhivko> is it ok to have this values just the same ?
[13:35:02] <maxcnc> keep Stepgen 25Percent more
[13:35:15] <zhivko> aha - OK !
[13:35:36] <zhivko> clear
[13:40:26] <maxcnc> zhivko: can you take a look inside the integrator manual
[13:40:41] <maxcnc> there are all the INI states discribed
[13:42:14] <zhivko> I will... thank you.
[13:42:41] <zhivko> I can imagine it sounds like a lame question.
[13:42:48] <zhivko> Sorry for taking your time
[13:42:54] <maxcnc> NP
[13:44:00] <maxcnc> there is no gemetry setup for interpreter like moves in Display maybe MK does need that but on A axis in use whoudt be good to tell the mahine how to use it
[13:44:05] <maxcnc> ok im off
[13:44:30] <MrSunshine> quite alot more stiffness in the machine now than before =) but i nee dto replace the steel wire system somehow =)
[13:46:33] <enleth> MrSunshine: what did you change to make it stiffer??
[13:46:54] <MrSunshine> http://postimg.org/gallery/2zc6fix38/160809ee/
[13:47:05] <MrSunshine> replaced the threaded rods to the ballscrew mounts
[15:12:14] <CaptHindsight> WTH, 2 different spindles, 800W and 1.5KW, same physical size, same manufacturer ..
[15:12:20] <CaptHindsight> http://www.amazon.com/Taishi-Bearing-Spindle-Engraving-Rpm24000/dp/B011QB3QM0
[15:12:40] <CaptHindsight> http://www.amazon.com/Bearing-Spindle-Engraving-Milling-Rpm24000/dp/B011WN0MTW
[15:12:45] <CaptHindsight> same price
[15:12:59] <CaptHindsight> do they just make up the specs?
[15:19:34] <_methods> no the guy with the lesser specs is the only one telling the truth lol
[15:19:43] <CaptHindsight> heh
[15:20:04] <JT-Shop> does newegg.com work for anyone?
[15:20:10] <_methods> no it's down
[15:20:15] <_methods> i just tried to go there and got nothing
[15:20:16] <JT-Shop> ok
[15:20:17] <t12> they dont specify running lifetime
[15:20:18] <t12> so i mean
[15:20:21] <t12> maybe both are correct
[15:20:23] <CaptHindsight> was working 2 hours ago
[15:20:43] <JT-Shop> yea I know, I'm trying to order some memory
[15:20:45] <_methods> i just tried to go there about 5 min ago and got nada
[15:20:54] <CaptHindsight> 1.5kw for 1 hour. .8kw for 100 hours, etc
[15:22:03] <CaptHindsight> :( no newegg now
[15:22:18] <CaptHindsight> was probably me
[15:22:30] <CaptHindsight> everything is breaking today
[15:26:14] <_methods> hehe
[15:26:42] <Jymmm> _methods: Was it you that has an expedition?
[15:26:49] <_methods> nope
[15:26:52] <Jymmm> k
[15:27:11] <_methods> tacoma
[15:27:50] <Jymmm> _methods: Ah. I just finished installing a LED lightbar behind the grill of my expedition
[15:27:53] <gregcnc> has anyone ever seen Leader Chuck MMX modular vises? i can't image leader makes these, but I can't find them anywhere and emailing leader got nothing. http://leaderchuck.com/media/mmx.jpg
[15:28:08] <t12> do all these yaskawa, mitsu, etc servo motors
[15:28:12] <t12> just have their own mount standards?
[15:28:16] <CaptHindsight> Jymmm: no need to search just wondering if you have found a LED spotlight with very narrow beam <20deg actual and <100W
[15:28:21] <t12> as a big FU to nema
[15:29:24] <Jymmm> CaptHindsight: To better answer, what's the application?
[15:29:44] <CaptHindsight> t12: are they larger than 3HP?
[15:29:50] <t12> the itty bitty ones
[15:29:53] <t12> like 100W
[15:30:10] <CaptHindsight> t12: yeah all over the place
[15:30:11] <t12> trying to scavenge junk together for this taig lathe
[15:30:22] <t12> i have nice linear rail/ballscrew assys i've accumulated
[15:30:48] <t12> but the one i'mt rying to use is coupled annoyingly to a yaskawa motor
[15:30:56] <t12> where the drive+cables are gonna end up being too much
[15:31:02] <CaptHindsight> Jymmm: 12V spotlight, narrow beam, very bright
[15:31:14] <Jymmm> CaptHindsight: and the appliction?
[15:31:24] <CaptHindsight> looking at stuff
[15:31:46] <t12> i guess i could look for a better ballscrew assy
[15:31:50] <CaptHindsight> housing is irrelevant
[15:32:06] <Jymmm> CaptHindsight: I have a Hello Kitty flashlight you can use that for
[15:32:35] <CaptHindsight> 30-100w version?
[15:32:43] <CaptHindsight> kewl
[15:33:17] <Jymmm> CaptHindsight: Vehicle? Marine? handheld? battery? stationary? pivoting?
[15:33:23] <CaptHindsight> any
[15:33:28] <CaptHindsight> 12v
[15:34:07] <CaptHindsight> ethereal, <100lbs, doesn't need OSHA, or NSA approval
[15:35:19] <CaptHindsight> very narrow beam, off the shelf...
[15:35:24] <ssi> I need a 10 degree spot as much light as possible
[15:35:28] <ssi> LED
[15:35:36] <ssi> I need like a 1000' throw or better
[15:35:38] <CaptHindsight> yeah I can add an lens but do I have to do everything
[15:35:44] <Jymmm> CaptHindsight: I found jsut the thing for you... http://military-vehicle-photos.com.s3.amazonaws.com/9074.jpg
[15:35:48] <ssi> CaptHindsight: if you find it I want to see
[15:36:41] <Jymmm> I have flashlight that have that.
[15:37:09] <CaptHindsight> Jymmm: narrow beam <20 deg?
[15:37:25] <Jymmm> sure
[15:37:43] <CaptHindsight> secret flashlight?
[15:38:01] <_methods> burglar light lol
[15:38:50] <CaptHindsight> has anyone caught this years flu?
[15:39:15] <CaptHindsight> the one year I don't get a flu shot......
[15:39:48] <CaptHindsight> fell asleep in my winter jacket last night
[15:40:20] <_methods> ugh that sux
[15:40:26] <_methods> i hate being sick or hurt
[15:40:36] * _methods is a big pussy
[15:40:44] <CaptHindsight> ok, have to brave the 72 deg F shop
[15:41:33] <CaptHindsight> whats weird is no other symptoms besides fever and tired
[15:42:01] <t12> i may have just
[15:42:03] <t12> and got over it
[15:52:03] <Jymmm> _methods: No, more like I can drive 75MPH using it alone on the freeway (if my headlights ever went out)
[15:53:08] <Jymmm> _methods: My "latest" flashlight (sadly) is the opposite... very floody
[15:55:38] <Jymmm> _methods: The lightbar I just installed on my car is 13K lumens, and surprisingly has more side throw than I expected (though I wish it had more, I'm very happy with it)
[15:56:43] <Jymmm> _methods: Eons ago, I had amber fog lights that had about 160 degree wide, so that was PERFECT for seeing things on the edge/sidewalk
[15:57:07] <Jymmm> can't find them for any reasonable price.
[16:21:03] <Deejay> gn8
[16:21:12] <Jymmm> Deejay: gn9
[16:21:44] <Deejay> =)
[16:43:33] <Loetmichel> Jymmm: i have a flashlight in my pocket that can do that...
[16:43:51] <Loetmichel> its just 6W Cree led tho with a lens in front
[16:54:39] <Jymmm> Loetmichel: Nice, this is no lens, just a deep reflector
[16:59:09] <CaptHindsight> how many specifications of a device can be posted at one time in IRC?
[16:59:34] <CaptHindsight> I found that more than 1 or 2 is the limit. Any more than that get ignored.
[17:28:49] <JT-Shop> Tom_itx: jepler fixed sserial! no more errors
[17:43:20] <Tom_itx> that's good news
[17:43:30] <Tom_itx> what was the issue with it?
[17:45:13] <JT-Shop> your asking me? lol I just test that stuff and whine or jump up and down for joy
[17:45:29] <Jymmm> lol
[17:45:41] <Jymmm> and ride tricycles
[17:45:54] <Jymmm> wierd ass tricycles
[17:46:01] <JT-Shop> and bicycles
[17:46:05] <Tom_itx> that's what most kids do
[17:49:16] <Frank__> guys i punched a hoel mark 0.5mm away from the exact position, do you know how to fix ? thanks
[17:49:22] <Frank__> Hole*
[17:50:14] <Tom_itx> lean the punch the way you want it to go
[17:58:52] <Frank__> like making a punched line?
[18:01:34] <Tom_itx> then once you move it a bit punch straight down again
[18:08:34] <SpeedEvil> This is yet another reason to emulate one-punch-man.
[18:08:40] <SpeedEvil> He never needs to repunch
[18:12:06] <JT-Shop> measure twice punch once
[18:12:14] <Tom_itx> that's my mottow
[18:12:16] <Tom_itx> motto
[18:12:38] <Tom_itx> finally got my catia homework assignment today
[18:12:43] <Tom_itx> i had it done yesterday though
[18:13:01] <JT-Shop> your too fast lol
[18:13:12] <JT-Shop> I need to find my solder station now
[18:13:15] <Tom_itx> it was bound to be a series of the problems in the back of the book... i'm doing all of them
[18:13:17] <Jymmm> Tom_itx: you must be in the future!!!
[18:15:05] <JT-Shop> https://www.youtube.com/watch?v=25LhUHKVYMo
[18:15:05] <Tom_itx> it's good practice anyway
[18:15:24] <JT-Shop> new probe tips on the way
[18:15:33] <Tom_itx> from?
[18:15:53] <JT-Shop> deephole1
[18:16:06] <JT-Shop> where I got the probe from

[19:29:13] <Jymmm> I have never heard of this, interesting... http://www.endtimesreport.com/dead_gen.html#Electric%20Drill
[19:30:00] <os1r1s> Does anyone know of an purchasable nema23 belt reduction aparatus?
[19:30:35] <Jymmm> liposuction?
[19:30:58] <Jymmm> do you mean a smaller pulley?
[19:31:33] <os1r1s> Jymmm Yeah, a way to gear up servos for more torque (and to slow them down)
[19:32:20] <Jymmm> you can use two pulleys, one being half the size/teeth as the other.
[19:32:38] <os1r1s> Right. I meant with the brackets premade
[19:32:51] <Jymmm> pulleys have brackets?
[19:33:11] <os1r1s> No, the mount to offset the nema23 servo so that you can actually use the pulleys with a belt
[19:33:12] <malcom2073> Jymmm: My generator has a similar thing
[19:33:29] <malcom2073> similar instructions
[19:34:40] <Jymmm> os1r1s: I really think that's going to dependon your setup and what/how you are mounting them to more than pulley offsets
[19:35:02] <Jymmm> as well as shaft length
[19:35:49] <t12> i have obtained a chinese 5c chuck
[19:35:57] <t12> i wonder how terrible/not terrible it is
[19:36:37] <Jymmm> os1r1s: Do you want something like this? http://www.ebay.com/itm/2PC-White-Alloy-Steel-Mounting-Bracket-For-NEMA23-Stepper-Motor-professiona-57mm-/201176553971
[19:37:05] <os1r1s> Jymmm No. Like this ... http://www.cnccookbook.com/img/MillStuff/CNC/Servos/P1011008.JPG
[19:39:17] <Jymmm> os1r1s: This is 2:1 right? http://guideimg.alibaba.com/images/shop/2016/01/10/70/cnc-engraving-machine-accessories-3m-timing-pulley-belt-set-reducer-ratio-8-1-for-nema23-2-phase-stepper-motor_14743870.jpeg
[19:40:18] <os1r1s> Jymmm I think that is 8:1, but the pulleys are easy to figure out. I'm looking for the alum brackets from that picture
[19:40:27] <os1r1s> It seems it would be reasonably standard
[19:40:30] <Jymmm> os1r1s: It was a joke =)
[19:40:33] <os1r1s> :P
[19:41:25] <Jymmm> os1r1s: I have seen something like this used.... a plate with holes and bolts http://powercordlabs.com/wp-content/uploads/2012/09/mounted-motor-e1348022107386.jpg
[19:41:31] <os1r1s> Then again, I may not need to gear it down much. Everyone looks at the continuous torque on the servo as being really low.
[19:42:33] <os1r1s> PetefromTn_ I noticed your comments on Hoss's g0704 thread on cnczone. Did you have one?
[19:42:51] <PetefromTn_> no I had an RF45
[19:43:21] <os1r1s> PetefromTn_ Did you use servos or steppers?
[19:43:29] <PetefromTn_> DC servos
[19:43:57] <os1r1s> PetefromTn_ Did you use a 7i77 or the like?
[19:44:05] <PetefromTn_> you can look at my long thread over there on the Zone it is called "Finally getting started"
[19:44:14] <PetefromTn_> no unfortunately
[19:44:30] <os1r1s> Let me look
[19:44:34] <PetefromTn_> I was not aware of the 7i77 and at the time I used MACH3 GASP!!!
[19:44:55] * Jymmm waits for the "PetefromFL Movie" to be released
[19:45:00] <Sync> speaking of which, thinking about converting my 45 to belt drive
[19:45:15] <os1r1s> PetefromTn_ So they were closed loop servos?
[19:45:19] <PetefromTn_> I did a belt drive conversion on mine
[19:45:24] <os1r1s> Sync Using gear reduction?
[19:45:27] <PetefromTn_> eh not really
[19:45:29] <CaptHindsight> StraightOuttahTenn
[19:45:40] <PetefromTn_> it was DC servos with Geckos
[19:45:59] <PetefromTn_> so it was closed loop to the drive but not to the control I spose
[19:46:05] <CaptHindsight> PetefromTn_: are you far from Chattanooga?
[19:46:08] <os1r1s> PetefromTn_ I'm trying to figure out if a belt reduction is really needed
[19:46:13] <Sync> os1r1s: no
[19:46:17] <PetefromTn_> about an hour and a half
[19:46:29] <Sync> the problem is that the gearbox is really loud at max rpm
[19:46:30] <PetefromTn_> My belt drive spindle had two ranges
[19:46:36] <PetefromTn_> and I ran it with a VFD
[19:46:38] <PetefromTn_> 3hp
[19:46:42] <os1r1s> PetefromTn_ For these for example ... http://www.automationtechnologiesinc.com/products-page/nema23-m-dc-servo-motor/skewed-rotor-design-nema23-dual-shaft
[19:47:05] <os1r1s> PetefromTn_ The peak torque is 350 oz/in, but the constant is 50 oz/in
[19:47:16] <Sync> well PetefromTn_ I have a servo just sitting here for that
[19:47:25] <PetefromTn_> I had 1125 OZ in motors from them on the RF45....a bit overkill
[19:47:27] <Sync> because dem torque
[19:48:05] <os1r1s> PetefromTn_ I put that on the Z, but was planning on others for the X/Y
[19:48:13] <PetefromTn_> I only got those because I found a fellow selling three of them basically brand new for about half of what they cost from Keling at the time...
[19:48:48] <PetefromTn_> If it is an RF45 I would probably get a larger motor for the Z than a 350 unless you plan to gear it way down
[19:49:06] <PetefromTn_> I had 3-1 ratios on the Z and 2-1 ratios on the X and Y
[19:49:16] <os1r1s> PetefromTn_ This is a g0704 size. On Z I have an 1125 oz/in. On X/Y I have the 350 oz/in
[19:49:38] <os1r1s> PetefromTn_ So even with those big motors you geared it down ...
[19:49:39] <PetefromTn_> Oh then that is probably overkill LOL
[19:49:56] <PetefromTn_> yeah I had timing belt drives on all axes
[19:50:08] <Sync> I'll probably also add gas struts to the Z
[19:50:14] <Sync> to reduce the stickslip
[19:50:32] <PetefromTn_> I had gas struts too LOL
[19:50:35] <os1r1s> PetefromTn_ Do many people direct drive servos on these, or is it a given that you are using a belt reduction if you go with a servo?
[19:51:34] <PetefromTn_> I dunno really...The millhead on my RF45 probably weighs as much as the 0704 so I needed the power to lift that damn thing plus the belt drive and 3 phase motor etc...
[19:53:25] <PetefromTn_> when it was finished the Z would rapid at about 250 IPM pretty good
[20:05:17] <PetefromTn_> Jymmm What exactly did you expect from the movie hehe
[20:19:14] <Jymmm> PetefromTn_: https://www.youtube.com/watch?v=VHpePQ6FCkM
[20:19:50] <PetefromTn_> hehehe that's Hilarious....
[20:20:04] <PetefromTn_> Fortunately I am FROM New York State tho ;)
[20:20:44] <Jymmm> Prove it, lets see your NY State drivers license!
[20:21:43] <PetefromTn_> well I was just a kid they don't let you drive til you're 16 there
[20:21:55] <Jymmm> Uh huh...
[20:22:06] <PetefromTn_> but I was born in Carmel and lived in Westchester if it makes any difference
[20:22:26] <Jymmm> Where you are born and where you are from aint the same thing =)
[20:22:38] <PetefromTn_> it is where I am from hehe
[20:22:56] <Jymmm> TN
[20:23:08] <PetefromTn_> Not for long :D
[20:23:29] <PetefromTn_> I turned in my notice at the race shop today... :(
[20:23:33] <Jymmm> PetefromTnForeverandEver
[20:24:13] <PetefromTn_> Petefrom Sittin on the beach drinkin' a Pina Colada fishing for Snappers and Groupers in the warm florida sun!!
[20:24:38] <jdh> got a contract?
[20:25:41] <Jymmm> PetefromTn_: This is you in the blue shirt... https://www.youtube.com/watch?v=NR69VbdBlho
[20:27:23] <PetefromTn_> yeah we have a signed contract on the house as of two days ago
[20:28:29] <PetefromTn_> I'm bad santa?4
[20:28:45] <PetefromTn_> BRB
[20:30:23] <jdh> congrats!
[20:37:18] <t12> chuck is ok
[20:38:11] <PetefromTn_> Thanks jdh
[20:39:17] <jdh> I'll be down there in march, you can buy me dinner!
[20:39:59] <PetefromTn_> sounds good man
[20:40:12] <PetefromTn_> we will not be there until the end of march tho
[20:40:46] <PetefromTn_> assuming the house passes the home inspection and the appraisal and we actually sell our closing date is March 21
[20:41:06] <Jymmm> Really? that long?
[20:41:41] <jdh> I'll be driving through PSL on the 24th
[20:41:49] <Jymmm> and it's been 4 days since you signed, you packed anythign yet?
[20:43:42] <Jymmm> malcom2073: I just never knew about the "de-energizing" generator thing.
[20:44:48] <malcom2073> Yeah, apparently there are a couple different types of generating motors, and that kind uses electromagnets for the field excitation. I suppose there is some reason for it
[20:45:02] <PetefromTn_> Jymmm honestly we requested the closing date to be that far in the future because as part of the deal we are doing a bunch of work inside the home so we needed the time to get it all done...
[20:50:13] <PetefromTn_> jdh well we may actually be there on the 23rd since we won't have a home here anymore LOL
[20:51:10] <t12> prepare for terror: https://www.youtube.com/watch?v=DBbwp6g8Kf8
[20:51:46] <malcom2073> House full of nope
[20:52:11] <CaptHindsight> I wouldn't be surprised if this guy was my neighbor
[20:52:31] <PetefromTn_> wth would you want those in your house for?
[20:53:15] <CaptHindsight> https://www.youtube.com/watch?v=AckIlQdQte4 the Museum of poo
[20:53:26] <CaptHindsight> figures
[20:53:34] <CaptHindsight> a Museum for everything
[20:53:43] <PetefromTn_> Yeah you'll forgive if I don't click that link ;)
[20:54:08] <CaptHindsight> hey it's in Italy
[20:54:18] <CaptHindsight> who knew
[20:57:36] <Jymmm> PetefromTn_: ah
[20:58:07] <Jymmm> Those "layered" nests are kinda cool.
[20:58:27] <Jymmm> tiered?
[20:59:58] <Jymmm> I bet he gets all the babes
[21:01:24] <Jymmm> the textures on some of those are unexpected
[21:05:52] <Jymmm> os1r1s: You might search on ebay for brackets as well.
[21:09:12] <cheetah2> to use linuxcnc do i need arduino?
[21:09:41] <Jymmm> it runs on a PC
[21:10:01] <cheetah2> i read i need a controller
[21:10:08] <cheetah2> was wondering if i could use arduino as the controller?
[21:10:16] <cheetah2> what is the most widely used controller?
[21:10:19] <CaptHindsight> PC as the controller
[21:10:35] <cheetah2> ok so what else do i need?
[21:10:50] <CaptHindsight> cheetah2: what are you controlling?
[21:10:51] <cheetah2> pc, serail breakout board, ...
[21:10:52] <Jymmm> motor drivers, motors,
[21:11:07] <cheetah2> do i need a breakout board?
[21:11:17] <Jymmm> parallel port or other I/O board, NOT arduino.
[21:11:45] <CaptHindsight> what are you controlling? what types of motors, how many etc
[21:11:50] <cradek> we can't recommend hardware without knowing what your goal is
[21:12:22] <cheetah2> oh ok
[21:12:31] <cheetah2> well can a 3 axis build any product or not?
[21:13:13] <cheetah2> im building clocks
[21:14:06] <cheetah2> how do you know when you cant build a certain part, the software tells you?
[21:14:28] <cradek> not really. a cnc control just controls the movement of the machine
[21:14:38] <cradek> how you make the machine move to cut a part is up to you
[21:14:43] <CaptHindsight> common sense to the CAM software alerting you
[21:14:52] <cradek> you probably need experience as a machinist to do this
[21:15:15] <cheetah2> i cant afford experience as a machinist
[21:15:24] <cradek> clockmaking requires cutting gears, for which you will need at least one rotary table, so no a 3 axis mill probably can't build a clock
[21:15:44] <cradek> have you cut a gear manually before?
[21:16:03] <cheetah2> im thinking ill build a cnc lathe later
[21:16:16] <Jymmm> cheetah2: Where are you from?
[21:16:21] <cheetah2> usa
[21:16:26] <Jymmm> k
[21:17:03] <cheetah2> ive seem machines where theres a lathe chuck that holds the work piece?
[21:17:04] <Jymmm> cheetah2: Do you have a budget already? any parts now?
[21:17:09] <cradek> for clock work, a cnc lathe might not be more useful than a manual lathe
[21:17:12] <trentster> howdy all
[21:17:17] <cheetah2> no i need cnc
[21:17:25] <cheetah2> i just want some advice before i buy things
[21:17:31] <cheetah2> to make it easy as possible for me
[21:17:41] <cheetah2> i know itll be hard but im ready to struggle
[21:18:16] <cradek> I suggest reading about clockmaking before you bother to learn about cnc and certainly before you start buying things
[21:18:19] <Jymmm> cheetah2: have you built clocks before?
[21:18:33] <cradek> there is a super good series on youtube about clockmaking - let me see if I can find it
[21:18:33] <trentster> Did anyone notice in the youtube tutorial I did that when the machine is running and I panned the camera onto LinuxCNC screen the toolpaths are running but there is no cone or tool showing the current location.
[21:18:55] <trentster> Is there something that needs to be configured to show this during running jobs?
[21:18:55] <Jymmm> trentster: it's shy.
[21:18:59] <cradek> trentster: I didn't see it, but you can turn the cone/tool on and off in the view menu
[21:19:13] <cheetah2> i already have stls i just need something to make the stls
[21:19:15] <cradek> trentster: also if the diameter (in the tool table) is very small you might not see it
[21:19:15] <trentster> cradek: its on permanently in the menu
[21:19:37] <cradek> cheetah2: unfortunately it doesn't really work that way
[21:19:41] <trentster> it shows innitially when I open linuxcnc UI for the first time and it has the demo linuxcnc code in there
[21:19:58] <cradek> check the diameter
[21:20:16] <trentster> cradek: nah it does not show at all ever, even when using 6mm or 12.7mm endmills
[21:20:21] <cheetah2> all i need is the pieces like the stls
[21:20:48] <cradek> cheetah2: his videos are really useful: https://www.youtube.com/channel/UCworsKCR-Sx6R6-BnIjS2MA
[21:21:08] <trentster> cradek: yeah clickspring channel is amazing
[21:21:13] <cheetah2> i cannot see youtube its blocked in my work computers
[21:21:16] <Jymmm> cheetah2: http://www.internetmachineshop.com/
[21:21:17] <trentster> that is an Aussie
[21:21:19] <cheetah2> by the firewall
[21:21:30] <trentster> He is meticulous! and obsessive about details
[21:21:36] <cradek> cheetah2: library?
[21:21:37] <cheetah2> i just need a machine that is versatile
[21:22:22] <cradek> cheetah2: I'm trying to help you succeed at making a clock - you can't feed STL files into a cnc machine and expect to get a clock - you just can't
[21:23:15] <cheetah2> yes ok but i need the cnc machine ill worry about the clock later
[21:23:20] <cheetah2> i have many projects i want to do
[21:23:59] <Ralith> I'm researching the construction of a DIY 3-axis CNC table in 4'x8' format. I'd like to be able to use it for both routing wood (and hopefully soft metals) and plasma-cutting sheet metal (I recognize switching between these will require a certain amount of effort to swap out beds). I'd like to build something high quality and am expecting to spend ~5-8k USD in pursuit of that, based on my reading so far.
[21:24:01] <cheetah2> is linuxcnc better than say going the arduino route?
[21:24:05] <Ralith> Can anyone recommend ...
[21:24:07] <Ralith> ... some well-regarded kits and/or plans? I've looked over cncrouterparts' kits, and they look pretty nice, but their support for plasma seems to be as of yet experimental. I've also looked at Precision Plasma LLC's site, which doesn't exactly inspire confidence, particularly regarding router use, but seems very competitively priced.
[21:24:12] <Ralith> hm, my IRC client broke that up oddly, sorry
[21:24:31] <cradek> Ralith: (it's a feature; irc has limited line length)
[21:24:51] <Ralith> cradek: I know, I installed the addon to do it, I'm just confused about why it chose to break line 2 after three words :P
[21:25:00] <cradek> ok I see that now, haha
[21:25:50] <Ralith> for further context, my expertise is mostly in software, but I'm comfortable doing my own wiring/integration, and I expect to have help from a competent amateur welder
[21:25:53] <cheetah2> i dont have a serial port. If i get one of those usb to serial would it work?
[21:26:56] <Ralith> I'd also be interested in any discussion of optimal stepper motor and motor controller selection for this usecase
[21:27:42] <cradek> cheetah2: no
[21:27:59] <cheetah2> i guess ill have to buy a whole computer?
[21:28:44] <cheetah2> do modern motherboards still have serial ports?
[21:28:47] <cradek> Ralith: I bet a 4x8' machine that can cut metal is very hard
[21:29:11] <Ralith> cradek: by 'soft metal' I mean 'aluminum, and anything else of roughly that difficulty'
[21:29:11] <cradek> cheetah2: linuxcnc doesn't generally need/use a serial port
[21:29:23] <cheetah2> really?
[21:29:25] <cheetah2> so usb?
[21:29:27] <Ralith> I've read many indications that wood routers can generally do aluminum with some effort
[21:29:32] <cradek> cheetah2: no, not usb
[21:29:50] <cheetah2> a lot of the motor kits have a serial breakout board. I thought i needed serial
[21:29:55] <Ralith> and as far as I'm concerned that's a neat bonus; my main interest is good-quality wood routing and sheet cutting
[21:29:57] <cheetah2> how do i communicate to the motor drivers then?
[21:30:00] <cradek> cheetah2: simple setups can use a parallel port. setups that need more performance use extra hardware such as a pci card
[21:30:09] <Ralith> someday I'll get a real mill for proper metalwork
[21:30:37] <cheetah2> Ralith: im looking for the same thing as you. I need to cut steel
[21:30:46] <cradek> Ralith: you might consider asking your question on the emc-users mailing list or the forum
[21:30:51] <Ralith> cheetah2: you will absolutely not be able to cut steel with an affordable large-format machine.
[21:31:06] <cheetah2> so i need a mill?
[21:31:11] <Ralith> cradek: thanks, I'll probably do that; just thought I'd start here
[21:31:14] <Ralith> cheetah2: yes.
[21:31:19] <cradek> a machine that cuts 4x8' pieces of steel would weigh 100 tons
[21:31:27] <cheetah2> ok
[21:32:30] <Jymmm> Ralith: cnczone might be a better option
[21:32:35] <cheetah2> im thinking of getting a siegx2
[21:32:49] <cheetah2> with nema 24
[21:32:57] <cheetah2> would nema 24 be enough?
[21:33:13] <Ralith> Jymmm: oh, of course
[21:33:26] <Ralith> cheetah2: NEMA 24 is a mounting interface standard.
[21:33:49] <Ralith> or something very similar anyway
[21:33:49] <cheetah2> oh
[21:34:09] <cheetah2> would any motor drivers work?
[21:34:13] <cheetah2> are they all compatible?
[21:34:54] <Ralith> cradek: as an aside, about when does a parallel port stop being a viable solution?
[21:35:55] <Ralith> cheetah2: motor drivers need to be matched to your motor and should be selected in consideration of the expected load
[21:35:56] <cradek> when it doesn't have enough inputs, enough outputs, or enough speed
[21:36:05] <Jymmm> more than three axis typically
[21:36:06] <cradek> so ... pretty quickly
[21:36:31] <Ralith> you can always just slap in another parport card for the prior two cases, no?
[21:36:32] <cradek> yes for running out of IO I agree with Jymmm - or with high microstep drives you can run out of speed easily
[21:36:54] <cradek> yes you can have as many cards as you have slots, but it doesn't fix the speed problems
[21:37:20] <Ralith> yeah; is speed capacity likely to be a serious problem for a 4x8 machine?
[21:37:32] <os1r1s> cradek That clickspring link is great. I have not seen it. Thanks.
[21:37:45] <Jymmm> Ralith: You "can", but that is typically when you've run out of I/O, at that rate, it's "simpler" just to use a mesa card with CRAPLOADS of I/O and speed
[21:37:46] <cradek> for wood you have to move pretty fast. it depends on your drives (microstep setting) and screw pitch or belt ratios
[21:38:14] <Ralith> but it's close enough to the edge that I certainly want to run the numbers before comitting one way or another, then
[21:38:24] <cradek> yes there are some great PCI/PCIe/ethernet solutions as well as EPP-based expanders that give you virtually unlimited stepping speed
[21:38:37] <Ralith> the mesa cards are the standard there, right?
[21:38:40] <cradek> lots of choices
[21:38:50] <cradek> they are a popular choice but not the only choice
[21:39:08] <Ralith> any resources you can point me at to learn more about the selection?
[21:39:10] <cradek> I have worked on retrofits with various mesa hardware and various pico hardware
[21:39:17] <Ralith> or should I just fall back on the forum
[21:39:21] <Jymmm> Ralith: No, it's not actually. a PP port card is what, $20? A mesa card is like $125. and the sheer amount of savings from all that tequilia and asprin you'll be saving will pay for itself.
[21:39:42] <cheetah2> would this work?
[21:39:43] <cheetah2> http://www.amazon.com/SainSmart-TB6600-Micro-Stepping-Stepper-Driver/dp/B00MQGSLNE/ref=sr_1_1?ie=UTF8&qid=1453777945&sr=8-1&keywords=stepper+driver
[21:39:43] <cradek> unfortunately I don't know of a good summary of the hardware options
[21:40:03] <Ralith> I saw a lot of references to mesa cards in the wiki/docs but I don't recall any others
[21:40:58] <Ralith> Jymmm: I meant "a large format router is, in general, close enough to exceeding parport speed limits to be a problem", but I was about to discuss price, so that's good to know too.
[21:40:59] <CaptHindsight> cheetah2: for a few $$ more you can get a much better stepper driver
[21:41:08] <Jymmm> Ralith: Mesa Cards http://www.mesanet.com/fpgacardinfo.html
[21:41:22] <cradek> cheetah2: I'm suspicious because of the cheap price, but on the face of it, seems fine, I see PUL/DIR, configurable microsteps
[21:41:22] <Ralith> Jymmm: yeah, I've browsed a bit
[21:41:26] <cheetah2> CaptHindsight: I dont see a serial port in it
[21:41:34] <cheetah2> how is the serial cable connected?
[21:41:43] <Ralith> Jymmm: the selection is a little bit overwhelming, but I figure I'll cross that bridge when I come to it
[21:41:49] <cradek> no common stepper drive uses serial connection
[21:41:50] <CaptHindsight> cheetah2: it has no serial
[21:42:05] <CaptHindsight> parallel port to stepper driver
[21:42:13] <Jymmm> Ralith: There are only two basic ones most are using with lcnc
[21:42:34] <Jymmm> Ralith: plus breakout board(s)
[21:42:54] <cheetah2> how do i connect it to the computer serial port?
[21:43:01] <CaptHindsight> Pulse and Step, so two parallel port connections per axis
[21:43:20] <cradek> huh I thought mesanet.com had a "here's what works with linuxcnc" page but I don't see it
[21:43:22] <Ralith> cheetah2: serial ports are pretty much never involved at any stage of a linuxcnc system
[21:43:27] <Ralith> cradek: they have a menu
[21:43:31] <Ralith> it contains many, many items
[21:43:33] <os1r1s> cradek Its in the store
[21:43:47] <cheetah2> ok how do i connect it to the parallel port on the computer?
[21:43:49] <Ralith> I think it just links their full anything I/O selection
[21:43:59] <os1r1s> http://store.mesanet.com
[21:44:03] <os1r1s> Top menu
[21:44:03] <Jymmm> http://store.mesanet.com/index.php?route=product/category&path=83
[21:44:03] <Ralith> i.e. http://store.mesanet.com/index.php?route=product/category&path=83_85
[21:44:08] <cradek> aha you're right! you have to go to the store first
[21:45:35] <Jymmm> Ralith: If you have a paraport, this will give you 4 axis http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html
[21:46:06] <Ralith> Jymmm: yeah, its power capacity seems a bit low vs. e.g. the motors the cncrouterparts kit recommends
[21:46:16] <Ralith> gecko drives do seem pretty nice in general though!
[21:46:17] <cradek> I think the g540 is not configurable microstep, so parport will limit your speed - be sure to do your math
[21:46:34] <Jymmm> cradek: 10 microsteps (fixed)
[21:46:42] <os1r1s> The G540 + the 5i25 work nicely together
[21:46:50] <cradek> yeah bet so
[21:47:00] <CaptHindsight> cheetah2: http://www.robocnc.nl/wp-content/uploads/2010/07/RoboElectronix2_Page_3.jpg LPT breakout board to 3 axis connections
[21:47:05] <cradek> even directly has the right plug
[21:47:50] <cheetah2> can i get a usb to parallel port for my laptop?
[21:47:57] <cheetah2> or have to buy a new computer with parallel port?
[21:48:02] <Jymmm> 5i25 http://store.mesanet.com/index.php?route=product/product&product_id=55
[21:48:12] <cradek> you can not use a usb adapter
[21:48:16] <CaptHindsight> cheetah2: not with Linuxcnc since USB is not realtime
[21:48:32] <Jymmm> You can use this 5i25 http://store.mesanet.com/index.php?route=product/product&product_id=55
[21:48:43] <cheetah2> would linuxcnc be my best choice? is the arduino type of cnc better in any way?
[21:49:03] <cradek> linuxcnc is the best choice
[21:49:25] <cheetah2> ive seen some arduino projects
[21:49:38] <os1r1s> cradek linuxcnc is much more capable.
[21:49:41] <Jymmm> cheetah2: You could have the parts made for you instead... http://www.internetmachineshop.com/
[21:49:43] <os1r1s> err, cheetah2
[21:49:50] <trentster> cradek: I used an arduino prior to moving to LinuxCNC.
[21:50:04] <cradek> bet you're not the only one
[21:50:06] <trentster> LinuxCNC is the way to go in my opinion.
[21:50:23] <zeeshan|2> long live linuxcnc
[21:50:24] <cheetah2> great
[21:50:29] <trentster> there is a major learning curve - as with most things but its worthwhile longterm
[21:51:02] <cheetah2> is there something a machine with a lathe type chuck in addition to the 3 axis up down left right forward backward can do that just the 3 axis cant?
[21:51:02] <cradek> cnc is complicated, as is machine building
[21:51:22] <Jymmm> cradek: not as complicated as girls =)
[21:51:29] <zeeshan|2> just make it 10x heavier
[21:51:32] <os1r1s> trentster If you just want to use a router and do 2.5D, chilipepper and tinyg are convenient.
[21:52:43] <cheetah2> how many axes can the parallel port support?
[21:52:53] <cheetah2> would it support a lathe + mill combination machine?
[21:53:29] <cradek> possibly, if you're very careful with your IO needs
[21:53:50] <trentster> os1r1s: perhaps it works for some folks - but there are some serious limitations with arduino based controllers. limited gcode and canned cycles as well as the ability to control stuff on the fly like speeds and feeds, pause and resume from specific points as well as tons of other useful goodies.
[21:54:14] <trentster> That being said the timing pulses on the arduino is pretty impressive for a $5 controller.
[21:54:44] <cheetah2> i would need 3 outputs for the mill, 2 for for the lathe one for the rotating chuck and one for the cutting thing right?
[21:54:51] <cheetah2> for 5 outputs right?
[21:54:52] <os1r1s> trentster Agreed. I've used it for PCBs where I don't really need the more advanced features. I did use mach3 for a while on my SherTaig Mill and Sherline Lathe. Now I've converted them to linuxcnc and wish I had sooner.
[21:55:05] <trentster> I kinda like the chillipepr conecpt - but I think its not great to need an internet conenction and a web browser to have to interface and control your cnc machine.
[21:55:06] <cradek> haha shertaig
[21:55:22] <os1r1s> cradek I put a sherline motor on a taig mill :)
[21:55:31] <trentster> os1r1s: btw I have a home built "DIY Router" and mainly do 2.5d
[21:55:36] <cradek> those sherline motors with the kbic control are awesome
[21:55:57] <os1r1s> cradek Yes I interface it through the G540 to linuxcnc for spindle control. Works very nicely.
[21:56:02] <cradek> very nice speed regulation
[21:59:19] <trentster> so guys if you wouldent mind taking a look at my video at around 18:55 - you can see the Linuxcnc not showing cone or tool https://www.youtube.com/watch?v=swa-eX0irPg
[21:59:43] <trentster> Would love some help with this as it really bothers me!
[22:01:51] <os1r1s> trentster That is weird
[22:04:07] <trentster> I know!!
[22:06:36] <zeeshan|2> has happened to me too
[22:06:43] <zeeshan|2> when you have too many lines :P
[22:10:06] <cheetah2> is more than 3 axis really needed?
[22:14:32] <trentster> zeeshan|2: was that for me?
[22:14:38] <zeeshan|2> ya
[22:14:53] <trentster> joke? or you have seen it happen before?
[22:15:04] <zeeshan|2> ??
[22:15:06] <trentster> btw this happens regardless of gcode complexity
[22:15:14] <zeeshan|2> its no joke
[22:15:16] <zeeshan|2> it happens to me too
[22:15:19] <zeeshan|2> very rarely
[22:15:25] <zeeshan|2> when i have a lot of 3d paths
[22:15:32] <trentster> so its some kind of LinuxCNC bug then?
[22:15:43] <zeeshan|2> the cone will dissapear for a bit, and will reappear after there is a big z move.
[22:16:00] <zeeshan|2> but i keep track of proress
[22:16:05] <zeeshan|2> progress, cause the line changes colors
[22:16:09] <zeeshan|2> *color
[22:16:44] <trentster> it is not a major issue I guess - just not great for filming videos to show other folks LinuxCNC in action when there is no reference of where tool is
[22:17:58] <trentster> maybe I should drop into dev channel and ask them if its a known bug, and if I should log a bug report
[22:47:11] <Ralith> Jymmm: would a 6I25 also be suitable?
[22:47:19] <Ralith> it can be hard to find PCI slots these days, sometimes
[22:52:48] <Tom_itx> same as a 5i25 only pciE
[22:54:59] <Ralith> cool, wasn't sure if the differences affected anything higher up
[22:57:28] <Ralith> as a software guy used to nothing being capable of talking to anything, I have to say it's really awesome seeing how freely you can seemingly mix/match parts for a CNC setup with just a bit of wiring and configuration
[23:15:03] <Jymmm> Tom_itx: you bought from ali before?
[23:59:22] <trentster> ok problem fixed - was my stuffup :-$
