[02:25:22] <Deejay> moin
[05:17:54] <jthornton> Morning
[05:19:11] <XXCoder> hey the evil printer
[05:20:12] <jthornton> finally got a good print, don't remember what I had to do lol
[05:20:25] <XXCoder> the mean chair?
[05:23:03] <jthornton> no the 20mm cube lol
[05:23:24] <XXCoder> nice. no zits and lines?
[05:23:33] <jthornton> and I think a LM10UU bearing holder
[05:23:52] <jthornton> the zits was from selecting random starts
[05:24:23] <XXCoder> yeah though with much lower acceration and proper return setting I disappeared mine
[05:25:50] <jthornton> with a billion settings you don't know if what you changed helped this problem or caused that problem lol
[05:26:19] <XXCoder> I usually change 2 or 3 a time
[05:27:27] <jthornton> lol yea that too
[05:28:01] <XXCoder> wow http://liquidmetal.com/
[05:28:21] <jthornton> guess I need to reboot the sat modem got a crappy connection
[05:28:29] <XXCoder> ok
[05:42:56] <JT-Shop> I still have problems with the top surface being rough with a few zits
[05:43:15] <XXCoder> look up pillowing
[05:43:30] <XXCoder> does it match that? there is more extreme cases but yeah
[05:47:55] <JT-i3> crappy connection can't load any pages
[05:48:14] <XXCoder> lemme link one picture
[05:48:36] <XXCoder> http://www.3dleerlijn.nl/wp-content/uploads/2014/11/pillowing.jpg
[05:48:38] <XXCoder> work?
[05:49:03] <JT-i3> yea, but the part is not that bad
[05:49:17] <XXCoder> yeah its more extreme
[05:49:26] <JT-i3> just a few random bumps and looks like it was too hot for the last layer
[05:49:52] <XXCoder> "The two most common causes are improper cooling of the top layer and that the top surface isnít thick enough."
[05:50:05] <JT-i3> ok
[05:50:25] <XXCoder> other is increase fan speed, check position and increase top layer thickness
[05:52:17] <JT-i3> no print fans yet, but I have 2 30mm 12v fans on the way
[05:52:22] <XXCoder> I had bad case of tgose before I printed dual duct fans
[05:52:35] <XXCoder> had to remove it but other settings made it not happen now
[05:52:49] <JT-Shop> http://www.thingiverse.com/thing:1264477
[05:53:17] <JT-i3> like that?
[05:53:27] <XXCoder> nah a sec
[05:54:38] <XXCoder> https://www.thingiverse.com/thing:1354526
[05:54:43] <XXCoder> I made varinant of that
[05:54:59] <XXCoder> I removed it because it keeps hitting that damned bot
[05:55:01] <XXCoder> bolt
[06:00:18] <jthornton> yea they need to be angled out at a 45 to miss everything
[06:03:23] <jthornton> for now I have a small oscillating fan that blows on the printer as it swings past
[06:04:35] <XXCoder> heh I have giant room fan
[06:04:49] <XXCoder> can use that move all air around room and should be enough if heat becomes an issue
[06:09:49] <XXCoder> geez
[06:10:00] <XXCoder> just saw a picture of survey
[06:10:06] <XXCoder> its about gender
[06:10:16] <XXCoder> 'theres usual suspects.,. and "chinese".
[06:10:17] <XXCoder> :P
[06:13:58] <JT-i3> the LM10UU holder looks good so far
[06:14:24] <XXCoder> nice
[06:14:31] <XXCoder> fidget toy? ;) kidding
[06:15:51] <JT-i3> for the 10mm Y axis rails
[06:16:17] <XXCoder> yeah
[06:16:32] <XXCoder> fidget toy seem to be really popular lately
[06:19:47] <JT-i3> http://www.thingiverse.com/thing:230139
[06:20:14] <XXCoder> hmm I wonder how printable that is
[06:21:49] <JT-i3> 23,666 downloads
[06:36:37] <JT-i3> I have a roll of PTEG black and carbon fiber on the way
[06:37:25] <XXCoder> nice :)
[06:37:57] <JT-i3> this part looks much better with 5 top layers, just a couple of zits
[06:38:16] <XXCoder> its not perment fix though
[06:38:23] <XXCoder> probably heat creep issue
[06:39:02] <JT-i3> the ID is still a tad small
[06:41:37] <XXCoder> easier to fix :)
[06:50:35] <pingufan> Hello, I want my LinuxCNC to also turn my vacuum cleaner on/off. I currently configured Pin 17 to be "MIST COOLANT", this is for controlling a magnetic valve for compressed air. I want to use Pin 16 for the vacuum cleaner. What shall I choose in stepconf fort it?
[06:56:04] <pingufan> I would like to use finally M7 (mist cooling) for forced air and M8 (flood on) for the vacuum.
[06:57:04] <pingufan> But I see that M7 is only Mist ON, M8= Flood ON, and M9 turns both OFF. I need a command for individually turning the vacuum on/off.
[06:58:22] <pingufan> Can somebody, please, suggest me a good way?
[06:58:27] <XXCoder> why have to be those? wonder if you can define your own m code?
[07:00:08] <pingufan> If it is easy to add a new M code, I fully agree.
[07:00:38] <pingufan> But I am not familiar with internals of LinuxCNC.
[07:01:04] <XXCoder> i not too, unfortunately
[07:01:05] <pingufan> Therefore I automatically tried to use existing ones.
[07:04:34] <pingufan> What G/M code is used to control "Digital output 0" (this name I can select in stepconf.
[07:08:15] <JT-i3> still have bridging problems too
[07:11:59] <pingufan> Can somebody tell me if linuxcnc.org is down?
[07:12:06] <JT-i3> yes
[07:12:18] <pingufan> I mean linuxcnc.org
[07:12:29] <JT-i3> yes
[07:19:34] <pingufan> Can I configure LinuxCNC for XYZA and ignore homing A ? My problem is: I haven't connected A always.
[07:20:11] <pingufan> When it is connected, it has an end switch, but this end switch will be separately then.
[07:20:31] <JT-i3> have two configurations
[07:21:42] <pingufan> Seems to be better.
[07:22:22] <XXCoder> pingufan: well one way is to manually trigger A trigger for homing
[07:22:46] <pingufan> Oh, no... No good idea.
[07:23:13] <pingufan> Because offline ... M62 is for controlling Digital Output 0 ?
[07:25:36] <pingufan> I usually use openSUSE. There it is okular. What is the PDF viewer in Ubuntu?
[07:29:53] <XXCoder> https://www.thingiverse.com/thing:624625 interesting
[07:31:02] <ktchk> Is the linuxcnc.org site down
[07:31:03] <ktchk> ???
[07:31:23] <pingufan> Any idea when linixcnc will be online again? All google references finally to it.
[07:31:24] <XXCoder> down.
[07:31:37] <XXCoder> ktchk: just google for "is site down or just me"
[07:31:44] <XXCoder> theres various websites that test for you
[07:35:05] <pingufan> It seems that digital outputs 0..3 are not very suitable to be independent On/Off outputs. What is the best choice to have an output for my vacuum cleaner? I want to control it with parallel port pin 16.
[07:35:09] <ktchk> Its down
[07:35:29] <jepler> we are aware of the outage of (www.)linuxcnc.org and are working on it. I don't have details beyond that right now.
[07:40:05] <jepler> It was a problem with the billing for the service. That's been taken care of, and the site is expected to be up again within the hour.
[07:41:48] <JT-i3> I've had that happen when my CC expired
[07:42:56] <XXCoder> JT-i3: https://www.thingiverse.com/thing:1461709
[07:44:13] <ktchk> I am installing linuxcnc heekscnc inkscape for a training cause with chinese router kits, have to restart tomorrow.
[07:45:01] <pingufan> I want to turn Mist and flood on/off independently. Is this possible?
[07:53:26] <pingufan> How can I TOGGLE M7 status and M8 status independently by using G-Code?
[07:54:43] <ToddZ> One good way to control parallel port pin 16 would be to use some M1xx code to setp the pin.
[07:55:12] <pingufan> Hi.
[07:56:50] <pingufan> ToddZ: I have to assign first some signal name to Pin 16. I tried with Digital Outout 0, but this does not add a checkbox to AXIS menu. I want to have something similar to Flood cooling and Mist cooling, that I can turn it on/off independently.
[07:57:11] <archivist> pingufan, http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m62-m65
[07:57:19] <pingufan> I don't know how AXIS does it, but the GUI allows to turn on/onn mist and flood separately.
[07:57:39] <ToddZ> You can use an M1xx code to setp the halui.mist.off and halui.mist.on pins to turn on off
[07:57:39] <pingufan> archivist: -> Server not found.
[07:58:26] <pingufan> ToddZ: Can you guide me? no docs online at the moment.
[07:59:27] <pingufan> ToddZ: I can live with M1xx commands, but I have no idea on which ones to use.
[07:59:43] <ToddZ> what are the hal pins and signal you need to connect to your parallel port pin 16?
[08:00:18] <archivist> pingufan, will be back up in a bit
[08:00:26] <pingufan> I am totally open for any suggestion. I think that Pin16 would be nice.
[08:00:29] <archivist> I can see the docs
[08:00:45] <pingufan> Great. I wait.
[08:00:52] <archivist> force a refresh in your browser
[08:01:40] <pingufan> archivist: does not work.
[08:02:11] <archivist> shift/ctrl refresh
[08:02:18] <JT-Shop> working here
[08:02:50] <pingufan> ToddZnope
[08:02:53] <pingufan> nope
[08:03:34] <XXCoder> well
[08:03:47] <XXCoder> sometimes it takes time to propate across internet
[08:03:48] <archivist> can be an ISP cache near you playing up, just have to wait
[08:03:52] <XXCoder> max 24 hours
[08:03:58] <XXCoder> I cant access either.
[08:04:08] <pingufan> Have you moved the server?
[08:04:23] <XXCoder> not always cache, as dns records need to be updated and some dns servers is slower
[08:05:29] <archivist> pingufan, http://www.collection.archivist.info/archive/mirror/Linuxcnc/m-code.html
[08:05:53] <pingufan> works. Thank you!
[08:05:59] <archivist> http://www.collection.archivist.info/archive/mirror/Linuxcnc/m-code.html#mcode:m62-m65
[08:06:25] <archivist> instant mirror of onepage only
[08:08:10] <pingufan> So I have to assign Pin16 "Digital Output 0" and thenn switch it on with "M64 P0" and off with "M65 P0" ?
[08:09:04] <archivist> try it
[08:10:42] <pingufan> I want to turn on the vacuum cleaner at program start, and turn it off on program end. And then, in another step, I want to turn on/off mist in a way that it is on only when I do cutting moves, no fast moves.
[08:11:05] <pingufan> I hope this reduces wood-dust in my workroom.
[08:11:48] <pingufan> I am often milling MDF, this causes extremely fine wood-dust.
[08:13:51] <pingufan> I will prepare the 40A SSR first. It will control the vacuum cleaner.
[08:15:10] <ToddZ> For your dust colection, I would just use two custom m codes (the numbers you choose to use are your choise.) I use M111 to turn on my vacuum table and M112 to turn it off.
[08:15:57] <ToddZ> You don't need to connect anything else to the parallel port pin when doing this, just setp it with the M-code.
[08:17:42] <pingufan> ToddZ: This sounds good! And how do I tell Linuxcnc that M111/M112 control pin 16 ?
[08:19:06] <JT-Shop> pingufan: http://linuxcnc.org/docs/2.7/html/gcode/m-code.html#mcode:m100-m199
[08:19:10] <ToddZ> if you look at the docs here there is an example http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m100-m199
[08:19:36] <gregcnc> it doesn't matter what your m code is. just connect it to the proper pins in linuxcnc and then the physical world
[08:20:00] <gregcnc> I'd just use M7 for mist and M8 for vac
[08:20:37] <gregcnc> trunging them on and off at the right time will be a function of getting the commends in the right place in your post
[08:22:50] <pingufan> gregcnc: This is not such easy, I think. M7 only turns ON "mist", M8 only turns ON "flood", and M9 turns OFF BOTH of them.
[08:23:10] <pingufan> But the M1xx method looks great.
[08:24:15] <pingufan> I didn't know that halcmd can be used from outside (by bash), I always thought this has to happen from inside linuxcnc.
[08:24:58] <gregcnc> you don't run the vac when a cut is made?
[08:26:07] <pingufan> VAC = vacuum cleaner for removing dust/chips, not for fixating the workpiece.
[08:30:16] <gregcnc> understood, but you know what you want to accomplish
[08:30:37] <pingufan> ToddZ: Where can I see the search path Linuxcnc is actually using? Or is it identical with the search path of the user?
[08:31:12] <ToddZ> It is in your ini file
[08:31:34] <skunkworks> ToddZ, are you Zuercher?
[08:31:44] <ToddZ> yes
[08:32:00] <skunkworks> Hi - I didn't know you were on IRC
[08:32:13] <ToddZ> not always
[08:32:52] <skunkworks> Thanks for all your help on the forum. I certainly haven't been helping as much as I want to.
[08:34:51] <ToddZ> Your welcom. I try to help because I was helped.
[08:37:03] <pingufan> ToddZ: So the M1xx command file has to be in nc_files?
[08:37:47] <pingufan> I hoped I can separate it a bit.
[08:39:16] <ToddZ> That is where I usually put them. don't forget to mark the file as executable.
[08:40:35] <pingufan> Can I add another directory to the path?
[08:41:05] <pingufan> I prefer to keep global settings etc isolated from milling jobs.
[08:52:06] <pingufan> ToddZ: Thanks for your kindly help. At least I get no error showing up. If it really works and M101/102 switch the port pin, I know soon. :)
[08:52:36] <pingufan> Have to build an adapter plug first.
[08:58:20] <pingufan> But from first glance, I would recommend to allow a separated directory for configurations (like self-defined commands). This would result in a cleaned up file structure..
[08:59:39] <pingufan> Currently I have all job files in .../nc_files. a directory .../user_commands would be great, then I could place generally used commands there.
[09:00:57] <JT-Shop> pingufan: http://linuxcnc.org/docs/2.7/html/config/ini-config.html#_rs274ngc_section
[09:02:12] <gregcnc> there it is
[09:26:25] <JT-Shop> sliced grapes and sauerkraut is surprisingly good
[09:27:38] <gregcnc> I'm probably going to have eggs over easy and sauerkraut for breakfast, hard boils if i'm lazy
[09:29:34] <JT-Shop> I had a tiny bit of cheese for breakfast
[09:29:54] <archivist> making me feel hungry
[09:30:08] <pingufan> Full agreement. :)
[09:30:30] <pingufan> My breakfast is a while ago. 9 hours.
[09:31:14] <ToddZ> PB&J for breakfast
[09:33:42] <pingufan> PB&J = PakedBeans & Juice ? :D
[09:36:46] <ToddZ> At least it was on home made bread.
[09:41:07] <MacGalempsy> mmm pbj
[09:41:08] <pingufan> does stepconf overwrite the .ini file? Wondering what will happen when I add something and use stepconf afterwards
[09:41:22] <pingufan> what is pbj
[09:41:32] <MacGalempsy> peanut butter jelly
[09:41:58] <pingufan> Uh - Where do you come from? USA or England?
[09:42:08] <MacGalempsy> usa
[09:42:21] <MacGalempsy> home of peanut butter
[09:42:34] <pingufan> I tried peanut butter, it is not my favorite. Too intense taste.
[09:42:56] <pingufan> I tried when I was driving along Route 66
[09:43:26] <MacGalempsy> nice. did you drive the entire length of rt66?
[09:43:36] <archivist> pingufan, stepconf overwrites, after hand editing you must hand edit
[09:44:18] <pingufan> Can I add the additional path to my own functions somewhere in stepconf?
[09:44:49] <archivist> stepconf is only for initial setup, hand edit files from then on
[09:45:23] <archivist> or learn how files are included and only hand edit those
[09:47:05] <pingufan> I see.
[09:49:13] <pingufan> archivist: You surely know a solution. The PC i use is using a VIA C7 1500 MHz CPU. Not very fast, but it runs fine. But randomly I get Realtime errors. I already rised the jitter value to 35000, does not have much effect. Where do this errors come from?
[09:50:09] <archivist> often video stealing too much time or the power saving
[09:50:40] <gregcnc> video, powersave, thermal control, take ssome effort to chase it down
[09:50:40] <pingufan> It is OnBoard Video.
[09:50:49] <archivist> I tend to chase around until I get a good combination of computer and video
[09:51:24] <pingufan> I don't loose steps hereby, so I think about somehow supressing this nasty message. Is this possible?
[09:51:26] <archivist> some onboard video steals too much time, try a plug in video card
[09:51:43] <MacGalempsy> pingufan: can you turn off powersavings in the bios?
[09:52:47] <pingufan> I can't remember that this old BIOS supports any power saving. But I would love when the PC could turn entirely off (this also does not work).
[09:53:54] <pingufan> This is a very small PC with Mini-ITX mainboard.
[09:54:25] <JT-Shop> pingufan: you get that error because of latency limits have been exceeded by a huge amount you may have millions of errors but you only get notified once per session
[09:54:44] <JT-Shop> run latency-histogram from a terminal for an hour or more
[09:54:47] <pingufan> I run it with a 60-speed memory card as HDD replacement
[09:56:01] <JT-Shop> also munching on fresh chives tastes like peanut butter...
[09:56:19] <MacGalempsy> hmm. never heard that before
[09:56:55] <gregcnc> strange chives you have there
[09:58:06] <MacGalempsy> jt-shopv did you get a ride in this AM?
[09:58:21] <JT-Shop> no, I've not left the shop
[09:58:26] <JT-Shop> did yesterday
[09:59:11] <MacGalempsy> lets see some prints! how many mods does the printer have so far?
[10:00:33] <JT-Shop> I added some feet and a different extruder
[10:00:53] <JT-Shop> http://gnipsel.com/images/prusa-i3-clone/
[10:01:19] <JT-Shop> mostly fiddling with slic3r settings trying to get the PLA to bridge
[10:03:11] <MacGalempsy> thats looking good!
[10:03:36] <MacGalempsy> have you been digging thre reprap wiki?
[10:05:01] <MacGalempsy> https://flic.kr/p/MMYE3w
[10:05:18] <MacGalempsy> That is xxcoder's chair bridge test
[10:05:25] <MacGalempsy> w abs
[10:08:47] <pingufan> I repeatedly think about buying a 3D printer, but what I (still) see is at so low quality level, that it is in best case "nice", a gimmick, but far away from professional (what I cannot pay). So I still have no 3D printer. :)
[10:10:17] <miss0r> My kid will be the death of me...
[10:10:34] <pingufan> Why?
[10:11:02] <miss0r> 10 months old. So I guess the usual stuff parents experience
[10:11:27] <pingufan> (rofl). Without knowing details... YES, ABSOLUTELY. :)
[10:12:02] <miss0r> The last few days have just been stacking up with my nights sleep being disrupted twice each night for a duration of 1,5 hours. poo/pee/vomit all over the place
[10:12:09] <pingufan> I have to leave, do some shopping. Thanks for your kindly help.
[10:12:21] <miss0r> have a good one ;)
[10:12:43] <miss0r> But now the mom is home, so I have some daddy time in the shop :)
[10:12:48] <pingufan> Bye!
[10:12:54] <MacGalempsy> miss0r: did you have pets before?
[10:13:11] <miss0r> MacGalempsy: I had a cat., why you ask?
[10:13:40] <MacGalempsy> some pets are more hassle than kids
[10:14:16] <miss0r> the poo/pee/vomit quantity is not quit compareable... also, I guess my wife would be mad if I just threw my son outside, when ever he gets over the top
[10:14:57] <miss0r> I'm just guessing here... I 'could' try it :)
[10:15:03] <MacGalempsy> lol. yeah. at least the kid is allowed in a hotel without a deposit
[10:15:18] <miss0r> this particular kid shouldn't
[10:15:34] <MacGalempsy> we have 4 dogs
[10:16:00] <miss0r> I don't suppose they are a product of broken rubber?
[10:16:07] <miss0r> (mines not.. he was planned :) )
[10:16:59] <MacGalempsy> please share your experience of dog impregnation!
[10:17:04] <JT-Shop> I just got a quote for the components to build a 90k machine and it's missing a bunch of slides and crap... that guy better get his head out of the water
[10:17:30] <miss0r> MacGalempsy: I better not :P
[10:17:49] <miss0r> well, atleast not I have some time to work on my proto type edm :)
[10:19:28] <miss0r> And I am sorry to just connect here to let out steam. But I guess during this parent leave, this is the most interresting people I get regular contact with :)
[10:20:18] <MacGalempsy> edm? wire or plunge?
[10:20:49] <miss0r> I'm starting with a plunge unit.
[10:21:19] <MacGalempsy> have u got the edm?
[10:21:21] <miss0r> at first the plan is only to be able to burn out taps and drills and stuff like that
[10:21:33] <miss0r> I don't.
[10:22:10] <miss0r> At the moment I am putting parts together(taking them down the shelf) to build the z-axis.
[10:22:23] <MacGalempsy> have you seen the diy psu?
[10:22:33] <miss0r> and I have some plans brewing in my head for the generator
[10:22:41] <miss0r> _the_ diy psu?
[10:23:20] <MacGalempsy> yeah. its a book that comes with a circuitboard and parts list.
[10:23:41] <MacGalempsy> i got it, but ended up buying a used machine
[10:23:52] <miss0r> I have not
[10:24:32] <miss0r> For the proto type, I am planning to use my vario trafo, rectify the output, feed it across some large caps, and switch the power with a large mostfet, driven by a tone generator.
[10:24:36] <MacGalempsy> let me grab the book
[10:24:36] <miss0r> that is the plan, atleast
[10:25:57] <MacGalempsy> title Build a Pulse EDM Machine, Author Ben Fleming
[10:26:26] <MacGalempsy> he charges $88 for the book and board
[10:26:43] <miss0r> Yeah, I was thinking of buying that book. You can't research diy EDM without stumbling across that one
[10:27:47] <MacGalempsy> if you are interested in it, i would cut you a deal for this one with board
[10:28:02] <miss0r> what is the board all about?
[10:31:00] <MacGalempsy> it is to build the pulse unit
[10:31:46] <miss0r> I almost figured that part myself :) but is it all included? as in: psu, controller, regulation. or just everything excluding the psu?
[10:32:40] <MacGalempsy> it is all
[10:33:00] <miss0r> I am interrested in that book. sure. What price were you thinking would be apropriate?
[10:33:05] <MacGalempsy> but its a bare board
[10:33:20] <miss0r> Yeah, I know. i will have to find components myself. that is no problem
[10:38:47] <miss0r> Also, where are you located? (if you are in the US, i'm thinking postage would kill) i'm here in Denmark
[10:39:07] <MacGalempsy> ah. im in the us
[10:39:21] <MacGalempsy> let me check.
[10:42:33] <MacGalempsy> $60us for flat rate
[10:43:25] <miss0r> holy crap. I mean, unless you basically give it away... Ben flemming charges 105$ for the kit with international shipping
[10:44:07] <miss0r> I'm thinking you should wait it out, and sell it to someone locally, so you can earn back a few bucks on it.
[10:47:55] <miss0r> MacGalempsy: Will you be around later? (I have to go eat dinner with the family)
[10:48:36] <miss0r> i'll be back later - OUT
[10:50:33] <MacGalempsy> laters
[10:50:55] <terkaa> Hi all
[11:36:51] <CaptHindsight> https://www.youtube.com/watch?v=zcM-1-siaO0 guess he doesn't know how to convert from L/M to CFM
[12:02:02] <Jymmm> CaptHindsight: Yeah, cause weight means quality
[12:05:28] <miss0r> MacGalempsy: i'm back. you still around?
[12:28:47] <IchGucksLive> hi
[12:31:53] <miss0r> I've just realised it pisses me off, that Electronic Dance Music, holds the same abbreviation as Electric Discharge Machining... it messes with my searches
[12:36:16] <pingufan> Since I played around with my configs and used hereby stepconf, I cannot get back the settings for overruling the feed rate. I had configured it for 200%, I would like to get that back. Where do I configure that? Please help.
[12:36:38] <jdh> try searching for ethernet/ip
[12:37:44] <miss0r> jdh: yeah :) I have a handbook for doubts there :)
[12:38:17] <pingufan> archivist: Are you here?
[12:39:24] <miss0r> Does anyone here have experience with aluminium on aluminium friction/lubrication?
[12:40:08] <IchGucksLive> hi pingufan
[12:40:27] <pingufan> Oh, yesssss. Aluminum. Are you milling that one from stores?
[12:40:32] <IchGucksLive> miss0r: depends on pressure surface
[12:41:03] <miss0r> pingufan: yeah. from mystery material
[12:41:50] <miss0r> IchGucksLive: i'm going to build a quill where weight is of the essence. hardly any load will be on it, as it will be used for EDM. a round quill I figure.
[12:41:51] <pingufan> I experience best results with 1-blade cutters, high rpm, and forced air. liquid cooling is not such important. I use endmills with not below 2mm
[12:42:28] <IchGucksLive> miss0r: that shoudt go with no problem
[12:42:42] <miss0r> pingufan: The machining is not the issue :) My worrie is with the finished project, where two aluminum surfaces will have to move inside eachother
[12:42:56] <miss0r> IchGucksLive: and perhaps some universal grease to make it go smooth? :)
[12:43:01] <pingufan> But I can only warn from using endmills wit more than 2 blades.
[12:43:27] <pingufan> And what's your fear?
[12:43:47] <miss0r> pingufan: i'm using some tool grade aluminum. I get realy good results with 4-6 blades, in flood coolant. Please do not ask me the logic in why it does not pack up on me
[12:43:48] <IchGucksLive> WD40 is inoph
[12:44:15] <pingufan> (rofl)
[12:44:46] <miss0r> I only use WD40 as coolant/cutting oil when I do line boring on the lathe.
[12:44:51] <miss0r> in aluminum that is
[12:45:29] <pingufan> Can one of you tell me whgere i can configure EMC to allow me overruling the feed rate by 200% ?
[12:45:49] <pingufan> I see always 120% as max.
[12:46:57] <pingufan> I already had that, but with playing around with stepconf I lost it.
[12:48:07] <pingufan> I edited the .ini file to "MAX_FEED_OVERRIDE = 2.0", but this changes nothing.
[12:48:14] <miss0r> pingufan: In the [DISPLAY] section
[12:48:34] <miss0r> ... what I was going to say.. That should change it
[12:49:19] <pingufan> I stopped EMC, then edited that line, then re-started EMC. Tada... Still 120% max
[12:50:11] <miss0r> Just shooting stupid questions here, you are sure you have the active ini, and not some backup/wrong file location?
[12:52:00] <pingufan> Well, my config is in "Meine-Fraese" directory. There I see only one .ini file, it is named Meine-Fraese.ini
[12:53:25] <IchGucksLive> pingufan: german
[12:53:43] <miss0r> and when you start your linuxcnc you make sure to use that config?
[12:54:27] <miss0r> Try excecuting it from terminal with linuxcnc 'directory to .ini' (without the ' ')
[12:54:57] <pingufan> Not any more. I opened the config folder now from the desktop link, there I see 1.2 configured. Wahhh - I hate this Ubuntu.
[12:55:52] <pingufan> I need 1 minute in KDE+openSUSE and 10 minutes for the same in Ubuntu.
[12:56:08] <miss0r> Ubuntu as its pros and cons like so many other dists. I used to be a Slackware guy, then I moved to Debian.. (This was before Slackware got its own package management, mind you - thats why I switched over)
[12:56:43] <pingufan> I'll never touch something else than SuSE.
[12:56:44] <archivist> pingufan, am now
[12:57:16] <pingufan> Oh, hi. I guess, menwhile it is solved. Except one thing. The defaults of the sliders in axis.
[12:58:23] <archivist> not something I have ever changed
[12:58:54] <pingufan> Can I somewhere configure the default of feedrate slider? It always starts with 100 mm/min, this is lots too slow.
[13:06:56] <archivist> pingufan, http://linuxcnc.org/docs/2.5/html/config/ini_config.html#sub:DISPLAY-section
[13:31:28] <os1r1s> Anyone cut foam?
[13:32:23] <Jymmm> yep
[13:33:19] <os1r1s> Jymmm I'm thinking about cutting some, but haven't done . I've always done wood/plastic/metal. Can you get decent foam to cut at HD/Lowes?
[13:33:35] <Jymmm> os1r1s: application?
[13:33:47] <os1r1s> Jymmm Was going to make costume parts for my son
[13:33:53] <os1r1s> :)
[13:34:31] <archivist> dont make costume stuff from flammable junk
[13:34:49] <renesis> like cotton
[13:34:51] <Jymmm> os1r1s: There's thicker too... http://www.homedepot.com/p/R-Tech-3-4-in-x-4-ft-x-8-ft-R-2-89-Foam-Insulating-Sheathing-310873/202530470
[13:34:59] <Jymmm> renesis: like titanium
[13:35:21] <Jymmm> os1r1s: but, why foam?
[13:35:21] <os1r1s> archivist That's good advice :)
[13:35:48] <os1r1s> Jymmm Easy to cut and light. I'm open to other ideas though
[13:36:06] <Jymmm> os1r1s: what are you making for a costum
[13:36:32] <os1r1s> Jymmm Transformer pieces. Mock tracks, armor, etc, etc
[13:37:12] <Jymmm> os1r1s: Dollar tree as sign foam board (1/4"), can be cut with a box knife
[13:37:55] <Jymmm> os1r1s: could use cardboard too
[13:37:59] <os1r1s> Jymmm Sounds intriguing. Just normal glue to tie it together?
[13:38:08] <Jymmm> orangey: or hot glue gun
[13:38:15] <os1r1s> Jymmm Cardboard wears so quickly ...
[13:38:17] <Jymmm> os1r1s: or hot glue gun
[13:38:34] <Jymmm> os1r1s: It's gonna be in the trash comme Nov 1st anyway
[13:38:38] <os1r1s> Awesome ideas. Thanks. Have you done something similar before?
[13:39:11] <Jymmm> orangey: It took me 6 months one time to prep for halloween =)
[13:39:23] <Jymmm> who the fuck is this damn orangey person?!
[13:39:39] <Jymmm> os1r1s: ^^^
[13:40:26] <os1r1s> Jymmm Nice. I created a tron costume 3-4 years ago for him. But he is really interested this year
[13:40:41] <os1r1s> So I'm going to try and make him devastator
[13:40:59] <archivist> you reminded me of this http://www.dailymail.co.uk/news/article-2820527/Claudia-Winkleman-s-daughter-eight-rushed-hospital-Halloween-costume-set-alight-party.html
[13:43:31] <Jymmm> os1r1s: Use cardboard as much as possible, then foam for some of the shapes is what I would do.
[13:44:20] <os1r1s> Jymmm He wants to be devastator. There are a bunch of things that need to hold a good shape, like tracks, dumptruck, dozer blade, etc.
[13:44:32] <os1r1s> But I will keep that in mind to use whenever possible
[13:45:09] <Jymmm> os1r1s: Again, it will be in the trash come Nov 1st. Adding that fine detail will take a LOT of work, and it's already the middle of october.
[13:45:32] <os1r1s> Good point :)
[13:48:11] <Jymmm> os1r1s: PLUS drying time for the paint
[13:48:34] <miss0r> You know the feeling when you are about to do something that will potentially ruin your work peice, but you go ahead anyway, even thou you are saying to yourself that it will never work. and then it goes to ruin the workpeice, and you are like "I told you so, why do you never listen to me" ?
[13:49:24] <miss0r> Well, that is it for me for tonight. have a good one
[13:49:31] <Jymmm> miss0r: There is also the... SON OF A BITCH, IT WORKED too
[13:50:00] <Jymmm> mikeh: thener you're all jumping around and giddy like a school gorl
[13:50:06] <Jymmm> girl
[14:08:15] <KreAture_Zzz> well, Linuxcnc is off the hook on my oversized parts
[14:08:39] <KreAture_Zzz> It was not the axis error setting for path follower, it was infact machine deflection, not tool deflection even
[14:08:46] <KreAture_Zzz> I need to stiffen the shit out of it!
[14:15:06] <Jymmm> duct tape!!!
[14:15:17] <Jymmm> foam-in-a-can!!!
[14:15:31] <Jymmm> 2 yards of concrete!!!
[14:18:57] <KreAture_Zzz> it can't be the profiles
[14:19:02] <KreAture_Zzz> math doesn't add up
[14:19:06] <KreAture_Zzz> must be the bearingblocks
[14:19:16] <KreAture_Zzz> luckally they can be tensioned
[14:19:18] <KreAture_Zzz> :)
[14:19:54] <archivist> machine flex is a common problem
[14:36:51] <englishman> hi guys, i have a watercooled spindle, what kind of stuff can i add to the coolant to prevent stuff growing in it, and maybe to prevent galvanic corrision on any parts?
[14:37:09] <KreAture_Zzz> archivist well I think I found the cluprist as my machine was originally designed to avoid the SBR20 in flex
[14:37:14] <KreAture_Zzz> only in compression
[14:37:23] <KreAture_Zzz> but I compromized to simplify construction
[14:39:56] <archivist> a dial test indicator will show how easy the machine bends
[14:55:51] <KreAture_Zzz> I have used that
[14:56:11] <KreAture_Zzz> and I found the exact same deflection i see in parts on machine at the same force as my calculator sais I put on it as cutting force
[14:56:14] <KreAture_Zzz> so it all adds up
[14:56:24] <KreAture_Zzz> I believe it is the SBR20 under tension instead of compression
[14:57:04] <KreAture_Zzz> http://kreature.org/projects/cnc/z_axis.jpg
[14:57:26] <KreAture_Zzz> The profiles forming the x crossmembers are already so stiff that the forces I see would deflect em 0.01mm
[14:57:41] <KreAture_Zzz> and they have the supportrails and the actual steel 20mm rails on em
[14:58:08] <KreAture_Zzz> Then on the x/z crossover plate I got the sbr's for the z to stiffen it up
[14:58:39] <KreAture_Zzz> a little stiffening wouldn't hurt on that plate to plate noint between motor plate and crossover plate though
[14:58:58] <KreAture_Zzz> the final z plate has two profiles (later) attached to stiffen it
[14:59:05] <KreAture_Zzz> and the spindle inbwteeen
[14:59:11] <KreAture_Zzz> inbetween
[14:59:18] <KreAture_Zzz> so that is also stiff
[14:59:31] <KreAture_Zzz> BUT, when one set of z bearings act as fulcrum the other is under flex
[14:59:40] <KreAture_Zzz> same goes for x axis bearings
[14:59:43] <KreAture_Zzz> upper vs lower set
[14:59:56] <KreAture_Zzz> I am pretty sure that is the problem
[15:00:13] <KreAture_Zzz> on my y axis I use the linear guides on the side to avoid this exact issue
[15:00:51] <KreAture_Zzz> http://kreature.org/projects/cnc/build_10.jpg
[15:01:25] <KreAture_Zzz> y leadscrew position is also a bit compromised as I haven't yet fitted the last fastening screw into the end of the upper y profiles
[15:01:34] <KreAture_Zzz> That will tighten it up a bit there
[15:01:36] <KreAture_Zzz> :)
[15:02:55] <Erant> Hot damn I'd forgotten how expensive wire is.
[15:03:54] <Erant> I need like 25ft of 16 conductor (8 twisted pairs) wire. $50-60.
[15:04:45] <KreAture_Zzz> lol
[15:04:55] <KreAture_Zzz> go wireless
[15:04:56] <KreAture_Zzz> :
[15:04:59] <KreAture_Zzz> :p
[15:06:02] <Erant> KreAture_Zzz: Read your datasheet btw
[15:06:13] <KreAture_Zzz> I have
[15:06:15] <Erant> Cute device, but I don't see any reference to multiple adjustable clocks.
[15:06:40] <KreAture_Zzz> oh you are on the controller
[15:06:45] <KreAture_Zzz> which are you refering to ?
[15:06:49] <KreAture_Zzz> which device ?
[15:06:51] <Erant> AX9... something
[15:07:00] <KreAture_Zzz> ahh yes the ax99100
[15:07:12] <Erant> That one.
[15:07:20] <KreAture_Zzz> you can use the clock in the spi if you do not connect stuff using the local bus mode
[15:07:39] <Erant> Ah
[15:07:48] <KreAture_Zzz> I am pondering using a cheap cpld type device that can do counters and such, and combine that with the local bus mode
[15:08:06] <KreAture_Zzz> then memorymap the whole thing so you get 24 pulse generators with counters
[15:08:06] <Erant> Should work
[15:08:18] <KreAture_Zzz> or just regular inputs if need be
[15:08:33] <KreAture_Zzz> The idea being memorymap can use a few registers to create a short fifo too
[15:08:38] <KreAture_Zzz> so you can keep it fed
[15:08:51] <Erant> Right. That'll be the tricky part.
[15:08:56] <KreAture_Zzz> ultra low cost, small design, and keeps most of the control in linuxcnc
[15:09:27] <KreAture_Zzz> There are some really cool dual access srams that could work for external use
[15:09:40] <KreAture_Zzz> They are surplus in china now so easy to get low cost
[15:10:00] <KreAture_Zzz> it's still a very interesting chip though
[15:10:18] <KreAture_Zzz> and I got pricing today for low volumes so now I know this will be fesible
[15:10:43] <KreAture_Zzz> I can get em for as low as $5 a piece in low volume
[15:10:50] <KreAture_Zzz> I was expecting 11-12
[15:10:58] <KreAture_Zzz> They scale down a lot in numbers though
[15:17:26] <KreAture_Zzz> Hmm, looking at some SBR graphs
[15:17:38] <KreAture_Zzz> I should be able to cut my flex down to 1/3 easily by adding some preload
[15:18:12] <KreAture_Zzz> I can possibly also fit another set of bearingblocks in there
[15:18:14] <KreAture_Zzz> :)
[15:18:19] <KreAture_Zzz> They are cherap after all
[15:18:21] <KreAture_Zzz> cheap
[15:47:17] <Bushman> hi guys
[15:47:44] <Bushman> i have trouble understanding what is happening with my A axis
[15:48:05] <Bushman> i want to recover a piece that has been stoped for other reasons
[15:48:34] <Bushman> but to do that i need the A axis to be "in sync" with the rest of the program
[15:49:12] <Bushman> so i tuched off all axes to match the actual position of the head, including A...
[15:49:51] <Bushman> but when i "run from here" the A axis is starting to move as if in relative mode
[15:50:41] <Bushman> i'm not sure what's happening since i have g90 active
[15:50:48] <Bushman> help please?
[16:07:56] <cpresser> Bushman: there is a page in the wiki somewhere explaining how to clear all offsets
[16:09:47] <Bushman> i've done that.
[16:10:05] <Bushman> as long i didn't run the program again it worked
[16:10:28] <Bushman> but after i've resumed the program everything went back to hell
[16:10:44] <cpresser> did you start on a line that has XYZA coordinates?
[16:10:59] <Bushman> i destroyed the piece by now so it doesn't matter.
[16:11:04] <Bushman> cpresser: yes
[16:11:13] <Bushman> one with G1 and Z
[16:11:25] <Bushman> then next one has X,Y and A
[16:11:38] <cpresser> hmm.. that should do
[16:11:45] <Bushman> i know!
[16:11:50] <Bushman> but it didn't
[16:11:57] <Bushman> oh well...
[16:12:20] <Bushman> that's only 4 hours lost... no big deal ;/
[16:15:17] <cpresser> there might be some other modal code in the header of your file
[16:15:31] <cpresser> not sure what else might habe been the issue
[16:17:19] <cpresser> did you write the gcode manually?
[16:41:40] <Deejay> gn8
[16:45:42] <Bushman> cpresser: no, it's generated from Slic3r. but i've read the file and i don't see anything in it
[16:46:26] <Bushman> there is G92 i've put there myslef tho
[16:46:51] <Bushman> in the postprocesor's "custom G-code" section i bring A to 0 with:
[16:46:56] <Bushman> G92 A0
[16:47:20] <Bushman> so i don't have to manually "zero" it before printing
[16:47:44] <Bushman> then there's only G21 and G90.
[16:47:51] <Bushman> and the moves start
[16:51:40] <cpresser> not sure how offsets exactly work. never used them. did you know there is "G10 L2" to set axis origins?
[17:35:44] <Bushman> cpresser: i know there is G10 lol.
[17:36:07] <Bushman> cpresser: don't really remember what each Ln did
[17:39:14] <Bushman> cpresser: ah, yes. i was using it once when i had to rotate coordinates system so that the part would fit into my limits
[18:40:31] <KreAture_Zzz> hoy
[18:40:35] <KreAture_Zzz> back
[18:40:42] * KreAture_Zzz popped by the workshop to play with the cnc again
[18:41:01] <KreAture_Zzz> I tested tightening the pretension on the linear bearings
[18:42:54] <KreAture_Zzz> It didn't seem to make a diff on finish but the sound improved a bit
[18:43:09] <KreAture_Zzz> Then I found that I had not installed the last stiffening on the motor brackets on y axis
[18:43:19] <KreAture_Zzz> so I drilled and tapped that and bolted it on with M8 bolts
[18:43:29] <KreAture_Zzz> The deflection on my testdial went down a lot then
[18:43:41] <KreAture_Zzz> but the dimension and finish is dead same :(
[19:32:40] <MacGalempsy> making chips?
[19:54:20] <KreAture_Zzz> hey MacGalempsy
[19:54:22] <KreAture_Zzz> yeh
[19:54:35] <KreAture_Zzz> been testing why I get oversized parts and tight holes
[19:54:47] <KreAture_Zzz> cuts nicely, albeit chatters easily
[19:58:09] <gregcnc> with or without radius compensation?
[20:00:01] <KreAture_Zzz> compensation done in pc
[20:00:11] <KreAture_Zzz> so no not in linuxcnc
[20:00:20] <gregcnc> have you measured the endmill?
[20:00:24] <KreAture_Zzz> yes
[20:00:36] <KreAture_Zzz> will try a climb vs conventional test tomorrow
[20:01:07] <KreAture_Zzz> I've gone through pretensioning bearings and adding the last bolts I had been putting off to stiffen the mountings
[20:01:31] <gregcnc> are you getting any taper inthe walls?
[20:02:00] <KreAture_Zzz> not that I notice
[20:02:04] * KreAture_Zzz measures again
[20:02:32] <KreAture_Zzz> I do actually
[20:02:42] <KreAture_Zzz> The last test I did of a 8mm dia square
[20:02:58] <KreAture_Zzz> it is 8.3mm at bottom and 8.2mm at top and wall is 2mm tall
[20:03:15] <gregcnc> what is radial engagement for finish pass
[20:03:16] <KreAture_Zzz> Is it maybe my spindle mount ?
[20:03:32] <gregcnc> that's a lot for 2mm
[20:03:44] <KreAture_Zzz> 0.3mm
[20:03:50] <KreAture_Zzz> yeah
[20:04:00] <gregcnc> endmill √ė?
[20:04:03] <KreAture_Zzz> must be deflecting entire collet and spindle
[20:04:05] <KreAture_Zzz> 3mm dia
[20:04:12] <KreAture_Zzz> I cut at 90mm/min
[20:04:13] <KreAture_Zzz> slow
[20:04:18] <KreAture_Zzz> rpm is 6500
[20:04:21] <KreAture_Zzz> brass
[20:04:24] <gregcnc> I'd go .1mm
[20:04:26] <KreAture_Zzz> 2 flute endmill
[20:04:34] <KreAture_Zzz> Yeh
[20:04:41] <KreAture_Zzz> I was really testing to see how fast I could go
[20:04:46] <KreAture_Zzz> finish is not perfect so it is too high
[20:05:06] <KreAture_Zzz> The force is not that high though so it should n't deflect that much
[20:05:14] <KreAture_Zzz> I may need to tighten my spindle mount
[20:05:32] <KreAture_Zzz> Thanks for the q, I didn't realize it tapered that much
[20:05:39] <gregcnc> use an indicator and push on the spindle to see what moves
[20:05:59] <KreAture_Zzz> I have
[20:06:14] <KreAture_Zzz> and it seemed that it was the Y axis drive
[20:06:17] <KreAture_Zzz> so I fixed that up
[20:06:23] <KreAture_Zzz> might have been multiple issues
[20:06:28] <KreAture_Zzz> will simply have to go over it again
[20:07:07] <KreAture_Zzz> I checked my first test too, it is indeed tapered
[20:07:35] <KreAture_Zzz> same height but 3.17mm at base down to 3.11 at top, but that ran slower

[20:08:18] <gregcnc> I think 0.3 is a lot for finish pass for 3mm tool I run 0.1-0.15 for almost everything
[20:08:34] <KreAture_Zzz> yeh I was just finding my way here
[20:08:48] <KreAture_Zzz> but the loads listed in calc seemed ok so I didn't think much about it
[20:09:13] <KreAture_Zzz> hey Loetmichel !
[20:09:39] <KreAture_Zzz> gregcnc I do think my efforts are paying off though
[20:09:43] <gregcnc> I've never tried to verify deflection from thoes calcaulators
[20:09:49] <KreAture_Zzz> I noticed the last test seemed to run smoother
[20:09:52] <KreAture_Zzz> less odd noises
[20:10:11] <KreAture_Zzz> well I knew the sideforces that were my limits
[20:10:20] <KreAture_Zzz> usefull for when you convert from depth to sideways etc
[20:10:29] <KreAture_Zzz> I had been finishing at 0.3 bottom and 0l.3 side simultaneously
[20:10:38] <KreAture_Zzz> turned out that was exact same load as my normal cuts!
[20:10:39] <gregcnc> getting feeds and speeds right takes some experience with home built machines. i don't run much brass
[20:10:43] <KreAture_Zzz> not a finish hehe
[20:11:04] <KreAture_Zzz> I was running 1.2mm woc with 2mm depth
[20:11:19] <KreAture_Zzz> and then when I did a 0.3mm depth and 0.3mm side for 2mm depth total I got same load
[20:11:29] <KreAture_Zzz> slot cutting is nasty vs side
[20:11:37] <KreAture_Zzz> I use scallop pattern to avoid slot
[20:11:50] <KreAture_Zzz> and then go ahead and do such a stupid finishing LOL
[20:12:04] <gregcnc> slotting also takes practice to be reliable
[20:12:21] <KreAture_Zzz> I guess I can reduce my material to leave setting though, not necessary to leave 0.3mm
[20:12:26] <gregcnc> had my fair share of issues slotting
[20:12:39] <KreAture_Zzz> I use a airjet to help lift chips
[20:12:57] <KreAture_Zzz> gregcnc https://www.youtube.com/watch?v=oTRIZYGJc2w
[20:13:09] <KreAture_Zzz> This is not anywhere as rigid as a mill
[20:13:13] <KreAture_Zzz> so everything has give
[20:13:14] <KreAture_Zzz> hehe
[20:13:29] <KreAture_Zzz> I think it does a smashing job for what it is, just need to learn to use it
[20:14:24] <gregcnc> yeah keep going it sounds OK, those are th 0.3x0.3 cuts?
[20:15:00] <KreAture_Zzz> think so yes
[20:15:36] <KreAture_Zzz> On other side of block there it did 2mm stepdowns 13mm deep
[20:15:42] <KreAture_Zzz> The bit is 15mm flutes
[20:15:59] <gregcnc> oh it's long
[20:16:18] <KreAture_Zzz> I had to fix the pegs on that part so they fit the gears but the part worked

[20:16:28] <KreAture_Zzz> gearbox running
[20:16:33] <KreAture_Zzz> 3 stage planetary
[20:16:48] <KreAture_Zzz> I replaced the output plate with a brass one as the original had a weak output drivedog
[20:17:12] <KreAture_Zzz> Now that I know I need to do much thinner finishing cuts it should be better
[20:17:41] <KreAture_Zzz> if I left 0.3mm and it tried to cut those at end but had already 0.3mm left from last cut not cutting where it supposed to I can see why it had a LOT of work on finish
[20:17:42] <KreAture_Zzz> hehe
