[00:08:03] <andypugh> I was running at a rather less frightening 55 volts: http://www.ebay.co.uk/itm/261239532385
[00:11:50] <MacGalempsy> tonight will be the fun of going through the wiring loom with a lablemaker and a notebook
[00:12:37] -!- _edward_ [_edward_!~quassel@] has joined #linuxcnc
[00:13:03] <andypugh> Probbaly time well invested
[00:14:45] <MacGalempsy> Agreed. Later, when I get into it, I'll hookup google hangout with my laptop. if anyone wants to hangout with pointers, it would be cool.
[00:15:11] <MacGalempsy> there is a hangout for #reprap. this channel needs a kthx bot
[00:18:35] <CaptHindsight> anything resembling rerap in here would be starting it down a slippery slope
[00:20:34] <MacGalempsy> the nice thing about the bot is that you can link to answers if no one is here to help out
[00:20:53] <MacGalempsy> I guess there reoccuring topics come up all the time

[00:21:37] <CaptHindsight> there is also a mail list and the forums
[00:22:07] <CaptHindsight> there are even heated discussions as to why one it better than the others :)
[00:22:20] <MacGalempsy> sure
[00:24:14] <CaptHindsight> plus KTHX doesn't really help, >90% of the issues are about adhesion and nobody wants to actually discuss surface tension and how adhesion really works
[00:25:24] <kwallace1> Thinking of Hangouts, that reminds me of the meeting in Germany. Is that going on soon?
[00:25:37] <andypugh> This weekend, I believe
[00:25:46] <andypugh> I forgot to arrange to go.
[00:25:53] <CaptHindsight> I thought it already happened
[00:25:57] <andypugh> (and it's my dad's birthday too)

[00:27:38] <kwallace1> It would be nice to schedule a Hangout there.
[00:28:50] <kwallace1> andypugh: It's just a stroll and a dip in the river for you.
[00:29:02] <andypugh> Aye, true enough.
[00:29:04] <CaptHindsight> how about next years fest in the US?
[00:29:21] <andypugh> I think next year's fest should be in the UK :-)
[00:29:33] <CaptHindsight> I'm in
[00:30:04] <CaptHindsight> London or in the 3rd World (Yorkshire)?
[00:30:48] <kwallace1> I wouldn't last that long in steerage.

[00:35:21] <MacGalempsy> that is the reprap hangout. many people just have their prints and printers going
[00:35:32] <MacGalempsy> kind of cool to discuss things and get pointers

[01:35:34] <PetefromTn> Thanks man. Never tried Google Hangout. Trying to get it configured here.
[01:36:52] <kwallace1> I use it once a week for meetings, but something changes every time we try it.
[01:38:26] <kwallace1> I don't have a camera or mic on this PC so I just watched for a while. There is a text chat available.

[01:40:45] <kwallace1> I'll try again.
[01:41:30] <PetefromTn> Yeah it also says he does not have any videos on there..
[01:41:53] <kwallace1> It seems to work for me. I just clicked the link, then the Join button.
[01:42:17] <PetefromTn> Is there a charge for these video calls?
[01:42:55] <PetefromTn> Okay nevermind it worked now LOL
[01:43:07] <kwallace1> No charge from Google.

[01:45:18] <PetefromTn> LOL is the video the electronics case you are looking at?
[01:45:31] <PetefromTn> Sorry I'm an ugly bastard..
[01:45:48] <kwallace1> Mac's is the green box.
[01:46:06] <kwallace1> He set up the camera then left.
[01:46:36] <PetefromTn> yeah but the camera is pointing at the electronics box green?
[01:46:43] <kwallace1> Yes.
[01:46:54] <PetefromTn> Cool... wheredego?
[01:47:17] <kwallace1> Who knows.
[01:47:22] <PetefromTn> could you see me?
[01:47:27] <kwallace1> Yes.
[01:47:35] <PetefromTn> I'm so terribly sorry...
[01:47:45] <PetefromTn> Pretty cool tho.
[01:47:55] <PetefromTn> So this machine is a boxford?
[01:48:02] <kwallace1> I'll get over it someday.
[01:48:07] <PetefromTn> LOL
[01:48:51] <kwallace1> It's a Benchman XT. I'll look for the eBay ad.
[01:49:23] <PetefromTn> is it CNC?
[01:49:38] <PetefromTn> nevermind..
[01:49:49] <PetefromTn> Heard of benchman before.
[01:49:55] <PetefromTn> Its a tiny machine no?
[01:50:06] <kwallace1> http://www.ebay.com/itm/121183132008
[01:50:53] <kwallace1> Sort of. It's a bench top, but the enclosure makes it seem bigger.
[01:51:30] <PetefromTn> Holy smokes that thing is 10k?? Well it does have a toolchanger.
[01:52:51] <kwallace1> I believe Mac made a $5 offer then waited for the guy to give in.
[01:53:47] <PetefromTn> LOL we're a bunch of cheap asses huh

[01:54:10] <PetefromTn> Hey theres movement!!
[01:54:27] <kwallace1> I'm not wild about the R8 spindle, but that can be fixed. It has servos.
[01:54:56] <PetefromTn> Sweet....
[01:55:07] <PetefromTn> If its R8 maybe you can use TTS?
[01:56:19] <kwallace1> Yes, TTS will work.
[01:56:57] <kwallace1> I'm not sure the tool changer grippers will work.
[02:01:23] <kwallace1> Have Mac hold a tool holder up to the camera.
[02:01:56] <kwallace1> Oh no the hammer is out.

[07:22:28] <terabyte-> http://www.flickr.com/photos/thespeedphreak/sets/72157636520041636/
[07:22:31] <MacGalempsy> Been working on the ATC logic board I/O. got about 80% of the wired figured out already
[07:22:56] <terabyte-> and
[07:22:57] <terabyte-> https://vimeo.com/77110096
[07:23:04] <terabyte-> password is "linuxcnc"
[07:23:21] <MacGalempsy> good work. that looks really nice. kit or homebrew?
[07:23:41] <terabyte-> thats a kit
[07:23:52] <terabyte-> http://www.cncrouterparts.com/crp4848-4-x-4-cnc-router-kit-p-137.html
[07:23:59] <terabyte-> im really impressed with it
[07:24:15] <terabyte-> now that i have a machine i might try to make one of my own later
[07:24:29] <MacGalempsy> it becomes addictive
[07:24:46] <archivist> it needed that much WD40 :)
[07:26:20] <MacGalempsy> I got a 3 wire lead coming out of the powerdrawbar air motor. anyone got any ideas?
[07:26:20] <terabyte-> ha ha ha ha ha ha
[07:27:24] <MacGalempsy> I thought encoder, but not enough leads
[07:28:37] <archivist> MacGalempsy, the switch connections so you know its open/closed?
[07:29:49] <MacGalempsy> very possible. I guess getting some air on the spindle would allow for an electrical test on the leads
[07:30:15] <MacGalempsy> archivist: you are thinking ground / Open loop / closed loop?
[07:30:16] <toastyde1th> valve?
[07:30:24] <MacGalempsy> no the valves are in the back
[07:30:26] <terabyte-> its 3:30am local time, good night folks
[07:30:43] <MacGalempsy> nighty night. congrats on getting the build done
[07:31:04] <terabyte-> thanks MacGalempsy
[07:31:14] <terabyte-> good luck with that extra wire
[07:31:15] <terabyte-> lol
[07:31:21] -!- terabyte- has quit [Quit: terabyte-]
[07:31:21] <MacGalempsy> ha!
[07:33:05] <archivist> you need to know when clamped or not before you move on/off a tool
[07:33:22] <MacGalempsy> agreed
[07:33:26] -!- voxadam has quit [Ping timeout: 240 seconds]
[07:33:51] <MacGalempsy> so now that I have all the wires figured out, I guess its time to start getting the logic down for a tool change
[07:34:46] <MacGalempsy> there are three pneumatic actuators with endstops, one dc motor with encoder, the air motor with endstop?
[07:36:43] <archivist> what no manual!
[07:38:10] <MacGalempsy> no the jerks at Light Machine Corp said no way
[07:38:57] <MacGalempsy> I may still brow beat them a little when it comes to that special occasion
[07:45:06] <archivist> I cant find them on the web
[07:46:04] <MacGalempsy> intellitek
[07:46:32] <MacGalempsy> http://www.intelitek.com/
[07:46:55] <MacGalempsy> I am curious about the 10 leads coming off the encoders
[07:47:04] <MacGalempsy> because the mesa board only has 8
[07:47:54] <MacGalempsy> may2 are power?
[07:50:53] <archivist> follow leads back to encoder and see the real partnumber, download data from other company
[07:51:24] <archivist> are they differential signals
[07:54:11] <MacGalempsy> I will do that
[07:55:03] <MacGalempsy> Right now I am trying to get the ATC controller card connections together. just about done for the fist phase. Then I can move on to the Mainboard
[07:55:27] -!- sumpfralle [sumpfralle!~lars@c.mail.systemausfall.org] has joined #linuxcnc
[07:57:51] <archivist> finding what the three wires do, add air operate each air solenoid, see what interconnections are on the three wires are with a meter
[08:01:36] <MacGalempsy> sounds like a good plan.

[13:54:00] <leonvnoord> hi guys, I have a question
[13:54:25] <leonvnoord> I'm new to CNC and getting started with it
[13:55:40] <leonvnoord> I would like to know how I can control a CNC machine using a breakout board and a parallel port
[13:56:25] <jdh> 1) install LinuxCNC, 2) hook up breakout board to parallel port, 3) hook up motors/etc to breakout board, 4) make chips
[13:56:43] -!- terabyte- [terabyte-!~terabyte@c-76-108-132-114.hsd1.fl.comcast.net] has joined #linuxcnc
[13:58:10] <leonvnoord> the point is that I want to control the CNC with my own embedded software. Should I create g-code with my software and the send it to linuxCNC?
[13:58:30] <leonvnoord> I have no experience with this, so things are not really clear to me

[14:01:53] -!- Laremere has quit [Ping timeout: 272 seconds]
[14:03:35] <ReadError> why re-invent the wheel
[14:05:49] <Tom_itx> agreed
[14:10:02] <leonvnoord> I'm using it for a laser cutting machine. My software calculates where the machine should cut. So I need to translate the output of my software to either g-code and send it to linuxCNC, or I need to speak to the breakout board to drive the cutter.
[14:10:32] <leonvnoord> That's what I think in any case.
[14:10:50] <Tom_itx> there are programs to translate it to gcode
[14:10:59] <Tom_itx> then let linuxcnc cut it
[14:12:09] <leonvnoord> 'it' is the result of my program, which is not a standard fileformat. So another option would be to create a file with a supported format from within my software, I guess.
[14:13:03] <leonvnoord> thanks for the input by the way :)
[14:13:38] <kwallace> If you are handy with software, you could modify the LinuxCNC interpreter.
[14:16:22] <leonvnoord> I am a software engineer, I'm not very used to interact with hardware so there's a lot of researching involved to get things clear :)
[14:18:16] <leonvnoord> Will look into the interpreter, thanks

[14:22:48] -!- vladimirek [vladimirek!~vladimire@] has joined #linuxcnc
[14:26:50] <jdh> linuxcnc handles the hardware fine, re-inventing that would be a major hassle.
[14:27:05] <archivist> leonvnoord, linuxcnc already knows about laser cutters, so outputting g code is probably the way to go

[14:39:00] <kwallace> archivist: I did a bit more work on my motorcycle CDI, it's looking like the rotor magnets are weak.
[14:39:32] <archivist> there are people who can remagnetise
[14:40:10] <kwallace> This guy is in the next town: http://www.oldengineshed.com/main.html
[14:40:29] <kwallace> I needed an excuse to go visit anyway.
[14:41:48] <archivist> magneto rebuilders have to do it on a regular basis
[14:42:49] <kwallace> I got this guy's coils a few years back, so I asked him about it: http://www.rickystator.com/
[14:42:59] -!- micalexander has quit [Remote host closed the connection]
[14:43:24] <kwallace> He said it is very unlikely the magnets would lose strength.
[14:44:18] <kwallace> They are ceramic from 1982 so I am suspicious.
[14:45:45] <archivist> I would be suspicious too
[14:46:35] <kwallace> I put a combination wrench on the magnets and it was fairly easy to remove. I'm used to coming close to damaging something playing with these.
[14:47:42] <archivist> if the magnets been left out, without the stator
[14:48:42] <kwallace> There is not much of a stator: http://www.wallacecompany.com/KDX250/
[14:53:40] <kwallace> The case was half full of water, for who knows how long, when I got it. I patched it together and rode it for a year, but now the ignition won't work.
[14:54:40] <archivist> I might be inclined to use a battery and just take the timing from the crank

[14:58:35] <kwallace2> From what I have read, the current fixed timing is a compromise between being able to kick start and high end torque. A magnetic pick-up and micro-p might improve that. I just don't need _another_ project right now.
[14:59:05] <kwallace2> It looks like I'm getting one either way.
[14:59:10] <archivist> but...but ...you know you do really :)

[17:35:50] <archivist> you might find some coolant hose from a car
[17:36:39] <Loetmichel> for extended flexibility: use a silicone tube meant for model airplane mufflers
[17:37:00] <Loetmichel> about the right size, stiff but not too stiff

[17:37:58] <Loetmichel> only caveat: be careful wenn you remove swarf coils, silicone tubing can be cut like jello

[17:55:42] <mevon> hey everyone how good are you? :P Can someone help me with my TB6560 board its kinda over heating my small nema17 motors and I was wondering if there is something to do besides going at 25% of 18V and lowering maximum speed?
[17:55:46] <andypugh> Ah, OK, so you didn't actually search on the Halfords site?
[17:55:54] <archivist> no
[17:56:20] <andypugh> mevon: Dropping voltage is the wrong way to do it. (and won't work).
[17:56:38] <andypugh> You need to lower the current limit.
[17:56:44] <archivist> steppers getting warm/hot is not a problem
[17:56:58] <mevon> andypugh: changing sensing resistors?
[17:57:04] <andypugh> He said "over heating" so I presume he means glowing red :-)
[17:57:26] <andypugh> Are there any current-setting jumpers on the board?
[17:57:26] <archivist> some jump at 50 deg c
[17:57:38] <archivist> wimps
[17:57:39] <mevon> andypugh: I didnt go that far, I didnt want to burn the small things
[17:57:55] <andypugh> They should be OK to about 80C
[17:58:04] <archivist> mevon, you cannot lean on my steppers
[17:58:43] <mevon> archivist: do you have heatsink on them?
[17:58:48] <archivist> when bolted to the machine, that should cool them
[17:58:51] -!- automata_ has quit [Ping timeout: 272 seconds]
[17:59:00] <archivist> the machine is the heatsink
[17:59:25] <mevon> i see :S
[17:59:48] <mevon> I have put the current setting to 25%
[18:00:09] <archivist> my B axis has the worst thermal conduction to the machine mass and gets to 50 dec c or more
[18:00:32] <mevon> but I will get a thermometer and see if i go over 80 deg cel
[18:01:34] <mevon> is it normal that the motors get hot when not movieng? eg: i lunch linuxcnc and without moving the thing the motors get hot..
[18:01:40] <archivist> http://www.archivist.info/cnc/stage8/IMG_0269.JPG the for ground motor on pillars
[18:02:19] <archivist> yes they get hotter stationary, it is the holding current
[18:02:20] <mevon> my motors are erally smaller then that

[18:07:34] <mevon> i think i have the cheapest nema 17 you can find: 17pm k502 p1st
[18:07:42] <mevon> the current settings helps a lot
[18:07:57] <mevon> they dont go over 35 deg c
[18:08:35] <archivist> lower current=lower torque, a trade off
[18:08:35] -!- realzies has quit [Changing host]
[18:08:43] <mevon> does it affect the max speed the motors ?
[18:08:51] <mevon> of*
[18:08:52] <archivist> use the right amount for the job
[18:08:55] <andypugh> No, that will stay the same
[18:09:24] <andypugh> Current = torque Voltage = speed.
[18:09:30] <archivist> well lower torque means you cannot achive the top speeds
[18:09:31] <mevon> ok because they sounded a little diff
[18:09:39] <mevon> ok
[18:10:33] <mevon> 25% is very low i think, ill try rising till heat is around 60
[18:11:21] <andypugh> archivist: I am not sure that is necessarily true. If the speed limit is the point where the back emf limits the current, then the speed will be the same at a lower current _limit_
[18:11:37] <archivist> I tested my machine with excess weight on the table, I still had to reduce the max acceleration to avoid it losing steps
[18:12:27] <archivist> time you looked at some speed v current and step rate curves maybe

[18:18:24] <mevon> hi IchGuckLive i made made configs to be inches

[18:19:04] <mevon> my power supply is 18V
[18:19:26] -!- zeehero [zeehero!4509ea63@gateway/web/freenode/ip.] has joined #linuxcnc
[18:19:37] <mevon> a little over the 12V of my small motors but I figured lower the current settings would do the trick
[18:19:43] <archivist> mevon, 18v is a little low
[18:20:29] <mevon> ok i see that now
[18:20:29] <zeehero> I've got a question - how strong of motors are recommended for various sizes of work areas?
[18:20:29] <archivist> one uses the voltage to achieve the set current quicker
[18:20:58] <archivist> zeehero, its about the mass being moved at a rate not the area
[18:21:41] <zeehero> archivist: I suspected as much, I honestly expect someone to sigh, throw a link my way containing information and I could go do the research myself - I'm having awful luck finding data purported to be reliable.
[18:21:43] <archivist> so use the right size for the job
[18:22:04] <archivist> there is a calculator somewhere
[18:22:23] <zeehero> That happens a fair amount in the reprap irc, heck the bot's job is to provide easy information for novices.
[18:22:43] <zeehero> Alright, is there a name I should look for in conjunction with the calculator?
[18:23:45] <zeehero> I'm aiming to build a large gantry system that supports a variety of toolheads for manufacture, 2ft by 2ft work area, with ideally about a foot or so of vertical (for the 3D printing side, less so for the milling)
[18:24:47] <archivist> gluegun is just shifting the gantry, where milling also has to deal with cutting load
[18:25:09] <IchGuckLive> mevon: 18V is to low why not 48
[18:25:19] <IchGuckLive> is it a TB6560
[18:25:45] <IchGuckLive> go at min to 24V
[18:26:16] <IchGuckLive> there is your head it takes to lang to build up the step more power

[18:26:57] <Jymmm> mevon: Screw 24, do 48+
[18:27:20] <zeehero> archivist: right, that's why to design this I need to look at the specifications needed for the most power hungry application - the milling, I'm not to worried abotu trading 3D printer speed for more accurate milling - I've already got a 3D printer that works fast enough for me, but I want to build a general-purpose machine that focuses more towards milling.
[18:27:22] <mevon> poor little guys... :( http://cncsuperstore.com/index.php?route=product/product&product_id=64
[18:27:54] <mevon> lol the power supply gave away before the motors hahah
[18:28:07] <mevon> 18V are gone now
[18:28:11] <mevon> :(

[18:29:06] <andypugh> mevon: Probably running a lt cooler now then?
[18:29:33] <zeehero> archivist: wood, plastic and aluminium predominently, but from what I am lead to believe a CNC milling machine could cut through harder materials by doing more shallow passes at a time - or is that incorrect?
[18:29:47] <mevon> andypugh: yeah this >sleep> feature is amazing!
[18:29:47] <archivist> ew that page does not state a max current
[18:30:10] <zeehero> One guy even suggested a wood milling machine with the right bit and enough passes could mill titanium, but I'm highly skeptical of that.
[18:30:18] <ReadError> awww yea
[18:30:27] <ReadError> i thought IchGuck how to english :)
[18:30:31] <ReadError> taught*
[18:30:32] <ReadError> looool
[18:30:52] <archivist> zeehero, yes as long as the machine is rigid enough, else you get flexing, chatter and tool breakage
[18:31:08] <mevon> http://www.ebay.co.uk/itm/Stepper-motor-MINEBEA-NEMA-17-Type-17PM-K502-P1ST-CNC-MILL-ROBOT-REPRAP-MAKERBOT-/171125797338
[18:31:16] <mevon> 0.6 amps it seems
[18:31:17] <Jymmm> zeehero: Heh, too bad you aren't closer, that's what I'm selling
[18:32:07] <zeehero> That's surprising - I work at a laser cutting facility so I can easily make custome parts for my machine, so if I can research what ensures rigidity I could possibly design a machine that could tackle about anything I could reasonably want to mill.
[18:32:28] <mevon> try the Mantis9.0
[18:33:27] <mevon> whats the best wire type to connect the motors to the electronics?
[18:33:32] <zeehero> It looks interesting.
[18:33:47] <andypugh> zeehero: Laurent is doing quite well milling aluminium patiently on an all-wood machine. http://www.youtube.com/watch?v=bJOY3dwpX_w&feature=share&list=UU_Mjlpaikgv_ysvx0z6G6WQ
[18:34:33] <mevon> http://makeyourbot.wikidot.com/mantis9-1
[18:34:39] <archivist> you can use a dti to detect flex and where to add webs to add stiffness
[18:35:30] <zeehero> mevon: aren't Nema 17s weak for a mill?
[18:35:46] <zeehero> That's what I've got on my RepRap after all.
[18:36:05] <FinboySlick> zeehero: All depends on how light your cuts are.
[18:36:43] <zeehero> FinboySlick: I'd like to be able to mill plywood within 12 hours...
[18:36:58] <mevon> yeah but for a mantis9.1 think its enought well it is in fact because it moves and cuts all right but Im on leadscrews so it has a good tork
[18:37:02] <zeehero> I know that the 70-oz-in motors I've got are weak compared to what milling machines use.
[18:37:13] <andypugh> Within 12 hours of now, you mean? That's quite a tight schedule.
[18:37:44] <zeehero> andypugh: haha, no, I mean I'm familair with how long it takes me to print with a 'gluegun' but that's really not fighting anything with a toolhead to remove material after all
[18:37:52] <FinboySlick> zeehero: with a router spindle, you don't really have to push very hard into the wood.
[18:38:18] <mevon> andypugh: whats the best wire type to connect the motors to the drives?
[18:38:20] <archivist> fun comes when the cut pulls the cutter into the material
[18:38:30] <FinboySlick> So long as you can move fast enough to keep it from burning the material (and fast-wearing your cutter).
[18:39:11] <andypugh> mevon: I don't really know. I used small flex conduit and individual wires on my steppers. But the servos are using Multi-Flex SY.
[18:39:30] <zeehero> FinboySlick: Well, I've got to keep in mind that I want to build a machine large enough to be able to cut a 2ft by 2ft work area, which might not be huge for cnc mills, it's huge for printers
[18:40:37] <zeehero> Hell, if I really wanted to, I'd dare to print an adaptor for my generic router and swap a toolhead on my printer to get a pathetic mill with no tool speed control
[18:40:38] <archivist> add some area for clamping
[18:40:47] <FinboySlick> zeehero: Stronger motors are always going to be a bonus, but you can get by with mechanical reduction and keeping your steppers at half or full step to maximize torque.
[18:41:16] <zeehero> archivist: yup, I knew it was going to have to be bigger, that's what I've been specifying work area for - how much clamping is needed by the way?
[18:41:31] <archivist> depends :)
[18:41:40] <zeehero> Of course it does, heh.
[18:41:51] <FinboySlick> zeehero: double-sized sticky tape can save you.
[18:42:01] <zeehero> FinboySlick: noted
[18:42:04] <FinboySlick> ... or ruin your day.
[18:42:07] <andypugh> mevon: This is the flex-conduit method: https://picasaweb.google.com/lh/photo/_yTAiDN3uUH1bGzbZiDfR9MTjNZETYmyPJy0liipFm0?feat=directlink I also swaged a flange onto the end of the conduit to screw it to the motor. I may have got carried away. :-)
[18:42:10] <archivist> its a bugger when you get a 3ft lump to machine
[18:42:10] <zeehero> FinboySlick: also noted
[18:42:39] <FinboySlick> I meant double-sided, btw.
[18:43:06] <archivist> we bent stuff getting it off the sticky
[18:43:30] <FinboySlick> archivist: I'm not sure that'll be the main problem with plywood though.
[18:43:38] <archivist> and also the following job never sticks properly
[18:44:17] <archivist> we were milling brass sheet stuck on a bit of wood
[18:44:33] <zeehero> Actually, I'm probably gonna be stupid and just try to build a CNC out of salvaged materials first, make my mistakes and learn straight away there.
[18:44:53] <zeehero> Then go to a kit and be much happier with standardized materials and instructions.
[18:44:54] <FinboySlick> zeehero: That's the best way to go.
[18:45:07] <FinboySlick> zeehero: I regret buying a machine not knowing what really matters.
[18:45:24] <mevon> andypugh: oh i see but man does it look good
[18:45:28] <andypugh> zeehero: You may go the other way, further away from kits.
[18:45:29] <FinboySlick> I'd have done better doing my own out of particle board and acme screws.
[18:45:32] <zeehero> FinboySlick: I've got gobs of components, like seven or eight salvaged steppers, and bunches of raw material.
[18:45:53] <archivist> zeehero, my first was from "scrap"
[18:46:24] <archivist> I keep adding and modding it
[18:46:38] <andypugh> On my current conversion I have been having castings made in iron, just to do the job "right"
[18:47:09] <zeehero> archivist: Yeah? Is that a common way to get into this hobby? I mean, I know I've got to get the electronic hardware yet but I prefer learning on the job and completing a project even if it fails to actually do what I aimed for it to do.
[18:47:19] <archivist> I made a new axis a couple of weeks ago for mine
[18:47:20] <FinboySlick> andypugh: Custom cast parts? Were they big?
[18:47:28] <andypugh> I maybe ought to do a YouTube "Tour" of the machine now that it is pretty much done.
[18:47:42] * FinboySlick interested in watching it.
[18:47:49] <zeehero> "Well I screwed this up, might as well keep going and see what this screw-up means to a finished machine." with safety goggles and a fire extinguisher handy
[18:48:27] <FinboySlick> zeehero: I think the most common way is getting a conventional mill or lathe on the cheap and converting it.
[18:48:48] <zeehero> Did that with my 3D printer and I learned how to print ABS without a heated bed so it seems to work for me.
[18:48:54] <FinboySlick> But for cheapo builds, building from scratch can be easier if you do it right.
[18:49:14] <zeehero> Hmm, I've read about manual mills a bit, are they really just a bunch of wheels to spin to move it by hand with the spindle going?
[18:49:24] <archivist> zeehero, I had an axis with too much friction (too little bearing area) so turned an axis 90 deg and made a new one on top instead of the small axis
[18:49:32] <mevon> zeehero: you use ABS plumbing and melted it in aceton?
[18:49:57] <zeehero> mevon: hmm? No, I don't do that.
[18:49:59] <andypugh> FinboySlick: The red parts here: https://picasaweb.google.com/lh/photo/15RdNsAOqS5YQYhRS5zPltMTjNZETYmyPJy0liipFm0?feat=directlink and here: https://picasaweb.google.com/lh/photo/7v3gpOZHcTunB0JRbsAT3dMTjNZETYmyPJy0liipFm0?feat=directlink and also in the Z-axis assembly here: https://picasaweb.google.com/lh/photo/KZ74w9eyFZzsWCbjBZy5eNMTjNZETYmyPJy0liipFm0?feat=directlink
[18:49:59] <FinboySlick> zeehero: They're often a bit more complex than CNC needs to be since cnc can interpolate a lot of the stuff you need special features for in a conventional mill.
[18:50:20] <mevon> zeehero: how do you solve the warping/
[18:50:25] <mevon> ?
[18:50:29] <FinboySlick> andypugh: Now that I see 'em, I remember you pasted those a while back actually.
[18:50:46] <zeehero> mevon: I make all my own models, I solve it trhough special consideration in the designs themselves.
[18:51:01] <zeehero> You don't need a heated bed if you make the model right.

[19:30:23] <jepler_> In v2.5 and later, you can write a multi-turn helical mill as a single g2 or g3. Specify P- when doing more than one full turn (e.g., P2 to do more than one but not more than two full turns)

[20:02:02] <WalterN> heh
[20:02:13] <WalterN> I'm looking for a BT40 one of those
[20:02:40] <kwallace2> Maybe another shot of interest: http://www.wallacecompany.com/tmp/img_2129-1b.jpg Pile-up on poor Seb.

[20:08:46] <WalterN> andypugh: how does the coolant/air connect to it?
[20:08:48] <cradek> ah
[20:08:59] <cradek> I think I probably saw you a few times then, but maybe we never talked
[20:09:31] <andypugh> WalterN: No Idea. Anyway, what was wrong with the one you showed me the link for? That was BT40
[20:09:31] <WalterN> andypugh: there is a stub there off to the side, but is that like a pipe thread or something?
[20:09:47] <WalterN> well
[20:09:52] <WalterN> I'm looking at this one... http://www.ebay.com/itm/Nikken-Tool-Holder-Coolant-Inducer-CAT-40-/171132352223?pt=BI_Tool_Work_Holding&hash=item27d84876df
[20:10:31] <andypugh> I think you have a hole with an O-ring mounted on the machine
[20:10:43] <WalterN> hmm
[20:11:37] <WalterN> I'll look at it once the part is done
[20:11:44] <andypugh> It doesn't look like rocket-science to make one.
[20:12:20] <WalterN> we are really limited right now with capabilities as a startup company
[20:13:59] <WalterN> we'll see
[20:15:43] <kwallace2> Cool, my eBay VFD and Digikey stuff just arrived.
[20:15:49] <JT_Shop> WalterN, one way that works well is to drill a hole bigger than the endmill and start at the center with the endmill
[20:16:32] <WalterN> JT_Shop: to put a nice 1.502" +-0.002" hole?
[20:16:41] <andypugh> WalterN: http://www.cftsystems.com/images/literature/cft-innovations-brochure.pdf shows one on a machine on page 2
[20:18:55] <WalterN> andypugh: ooo thanks
[20:18:57] <JT_Shop> WalterN, I guess that depends on your machine if the final hole is nice or not
[20:21:46] <WalterN> JT_Shop: if it was me I'd probably drill a 5/8 or 7/8 hole then hollow out most of the rest of it with a 1" cob roughing endmill
[20:22:18] <WalterN> like this http://www.mscdirect.com/product/06822043
[20:22:26] <andypugh> I would use a boring head. :-)
[20:23:00] <andypugh> But only because I have a nice boring head that I enjoy using
[20:23:04] <WalterN> then something like that for the finish pass

[21:53:45] <andypugh> That's not an RTAI error
[21:54:06] <andypugh> you probably need to remove the lp module

[21:54:45] <andypugh> If that works then you probably need to blacklist lp

[22:44:07] <mevon> hello
[22:44:07] <MacGalempsy> so last night, I was able to lable and category all the connections to the Benchman XT mainboard and atc controller. still have a few items to determine what they are.
[22:45:01] <mevon> heres an easy one, I hit the homing for a said axis, and instead of going towards x=0, it goes the opposite and never reaches home
[22:45:11] <mevon> can someone help me with homing?
[22:45:20] -!- Jp11 has quit [Ping timeout: 265 seconds]
[22:45:35] <mevon> is it in the homing accel where I need to make it negative?
[22:47:07] <MacGalempsy> what side it your switch on?
[22:47:39] <jthornton> negate the search and latch
[22:47:41] <mevon> got 2 actually but on the same input
[22:48:04] <jthornton> it should home to either switch
[22:48:08] <MacGalempsy> anyone ever seen an encoder with 10 wires coming out?
[22:48:41] <jthornton> I think mine do counting the shield and ground
[22:49:12] <MacGalempsy> i figured one of the extra is ground. what is shield?

[22:54:41] -!- AR_ [AR_!~AR@] has joined #linuxcnc

[23:01:21] <mevon> so anyone? what is better to have? a Min switch or Home switch?
[23:01:42] <jdh> might as well make it boh.
[23:02:05] <mevon> have you ever tried that?
[23:02:17] <jdh> yes
[23:02:28] <mevon> me its what I have and it doesnt work
[23:02:35] <mevon> did work for you?
[23:02:43] <jdh> works fine
[23:03:14] <jdh> my router has min/max wired to a single input and it homes to min
[23:03:39] <mevon> but in the machine.ini you have, how is it set?
[23:03:52] <mevon> home or Min?
[23:04:51] <mevon> it gives me limit switch errors
[23:05:13] <jdh> do you have HOME_IGNORE_LIMITS = YES for each axis?
[23:05:22] <jdh> are your inputs inverted?
[23:05:28] <mevon> inverted yes
[23:05:38] <mevon> ignore limits im not sure
[23:05:55] <mevon> its at YES
[23:06:48] <mevon> min is at -0.01 and home at 0.0, if min is home switch too it wont work
[23:07:09] <mevon> so no home switch
[23:07:12] <jdh> what is the msg and what are you doing when it is generated. You might pastebin your ini/hal
[23:08:02] <jdh> I have home at +0.1, min_limit 0.0

[23:11:37] <jdh> immediatly?
[23:11:40] <mevon> yes
[23:11:54] <mevon> immediatly when it reaches the switch
[23:12:14] <jdh> try making HOME slightly positive?
[23:12:36] <jdh> or not, I guess having MIN negative is the same thing.

[23:32:27] <mevon> all my switches are working properly
[23:32:38] <MacGalempsy> so did you go back through the software?
[23:33:05] <mevon> .hal and .ini, yeah I checked everything
[23:33:28] <MacGalempsy> when you pulse the motors, does the axis move in the correct direction?
[23:33:35] <mevon> yes
[23:33:48] <mevon> i had to invert the dir pins
[23:34:17] <mevon> also negate the home velocity
[23:34:18] <MacGalempsy> are you pulsing it manually or through the software?
[23:34:32] <mevon> im pulsing with the Home Axis button
[23:34:37] <mevon> in linuxCNC
[23:35:29] <MacGalempsy> it sound like a software issue.
[23:35:53] <mevon> so you are going to help me configure my switches corerctly?
[23:36:30] <MacGalempsy> i have not gotten to that point, I am still retrofitting electronics on my machine
[23:36:37] <mevon> oh

[23:48:00] <mevon> got Min and Max sw on my axis
[23:48:20] <mevon> whats the best way to configurate the switches for Homing at Min switche?
[23:48:23] <PetefromTn> sounds like my machine. There are several aspects to homing the axis.
[23:48:43] <PetefromTn> Gimme a second to re-read the literature for linux homing.
[23:50:03] <PetefromTn> Could it be your home index position is beyond the switch somehow?
[23:50:10] <mevon> what is best to keep? Home or Min sw?
[23:50:42] <PetefromTn> Not sure what you mean are you using your min limit as your home switch too?
[23:50:50] <mevon> my Home is at 0 and Min at -0.01
[23:51:11] <PetefromTn> are you using a home index position?
[23:51:22] <mevon> offset?
[23:51:31] <PetefromTn> yeah thats what I mean.
[23:51:31] <mevon> I dont have an Indexer
[23:51:45] <PetefromTn> no offset position.

[23:52:25] <mevon> nor a potentiometer of any sort giving the position
[23:52:35] <mevon> just a min and max sw
[23:52:44] <mevon> i wish to use min as home
[23:52:54] <PetefromTn> When you home the machine does it travel slow to the home switch, hit it, then back off and stop at a home offset position
[23:53:06] <mevon> yes
[23:53:29] <PetefromTn> Okay what I am asking you is if your home offset position is where it needs to be.
[23:53:42] <mevon> then the limit error comes
[23:53:51] <mevon> and turns off the machine
[23:54:07] <PetefromTn> Here you need to read this entirely to understand homing.

[23:55:30] <PetefromTn> You might try changing the homing order to see if it gets beyond the Y axis
