[02:17:38] <Jymmm> r00t4rd3d: Hey, whats the url for that site that has the chest instructions?
[02:33:27] <Jymmm> r00t4rd3d: Ah nm, found the box plans
http://www.vectric.com/cool-stuff/projects/2011/paradise-box.html
[02:38:24] <toner> hehe, I just made a box
[02:39:06] <toner> not quite as fancy, but it's just for a fridge controller
[02:41:22] <toner> it's pretty slick tho
[04:08:26] <mrsun> dumdidum, how to design the X/Z axis on the router ... got some 35mm hardened steel bars with ball bushings i could use for it =) tho need to shield them for dust later but :P

[06:04:34] <maximilian_h> Hello
[06:04:58] <maximilian_h> does somebody know if there is a gcode for mirroring coordinates of an axis ?
[06:05:17] <maximilian_h> because I'd like to replace an old cnc controller
[06:05:42] <jdh> you can rotate axes with G10 L2 P1 R<whatever>
[06:05:45] <maximilian_h> but the cam software, which I cannot replace, gives gcodes that mirror x and y
[06:06:05] <maximilian_h> hello jdh
[06:06:26] <jdh> G10 L2 P1 R90 or R270 would rotate x to y one way or the other
[06:06:50] <maximilian_h> let me have a quick look at the manual
[06:06:57] <maximilian_h> i'll be right back
[06:06:57] <cpresser> maximilian_h: there is a tool which can also perform that task:
http://code.google.com/p/grecode/
[06:07:34] <jdh> heh, that looks much easier. the other way confused me to no end when jogging and touching off
[06:09:59] <maximilian_h> neither will work I believe
[06:10:12] <maximilian_h> G10 L2 will not work because it rotates
[06:10:53] <maximilian_h> but if x coordinates stay the way they are and y is mirrored, then it is not a simple rotation
[06:11:45] <maximilian_h> and grecode, which I did not know yet, seems to rotate all coordinates in the cnc program
[06:12:12] <maximilian_h> however, in my case the x and y axes are mirrored before some subprogram is called
[06:12:32] <maximilian_h> so I cannot apply grecode to the whole program :(
[06:14:50] <maximilian_h> it only has to work in the xy plane, that is in the G17 setting
[06:15:10] <maximilian_h> and only axes x and y are affected
[06:17:45] <maximilian_h> does somebody know where the code for the gcode interpreter that translates G10 resides ?
[06:17:58] <maximilian_h> Because if there is a code for rotation already in place
[06:18:21] <maximilian_h> then adding some mirroring ?might? not be too hard

[06:35:05] <L84Supper> those were the days

[06:40:09] <r00t4rd3d> http://i.imgur.com/HvDw9F1.png
[06:44:16] <Tom_itx> maximilian_h there was a gcode but all the cutter paths would be wrong
[06:44:46] <maximilian_h> hello Tom_itx
[06:45:09] <maximilian_h> what means cutter paths could be wrong ?
[06:45:37] <Tom_itx> if you mirror it, what was conventional cuts will be climb
[06:45:39] <maximilian_h> and what gcode do you refer to please ?
[06:45:48] <Tom_itx> i don't recall off hand
[06:46:34] <maximilian_h> I could live with the cutter paths, since the cnc controller that I'd like to replace does not have the functionality anyway
[06:46:54] <maximilian_h> do you know who I could ask ?
[06:46:54] <Tom_itx> on a Fadal it was G51.1
[06:47:22] <Tom_itx> and mirror image cancel was 50.1
[06:47:52] <maximilian_h> yes, here it is G39 x1 y1 for mirroring in x and y
[06:47:54] <Tom_itx> probably not implemented in linuxcnc
[06:48:03] <maximilian_h> or G39 x0 y0 to switch it off
[06:48:20] <maximilian_h> too bad if it is not implemented ;)
[06:48:31] <Tom_itx> your cutter paths would be backwards though
[06:48:39] <Tom_itx> we didn't use it much
[06:48:44] <maximilian_h> do you happen to know there in the source code the conversion of G10 takes place ?
[06:49:01] <Tom_itx> all your lead in's and lead outs would need adjustment too if they were too short
[06:49:06] <maximilian_h> i mean the conversion of the coordinates ?
[06:49:22] <Tom_itx> no
[06:49:50] <maximilian_h> I can live with the cutter paths since it is a water cutting machine
[06:50:11] <maximilian_h> and the diameter is compensated in the cam software
[06:50:16] <Tom_itx> oh only a 2d path then
[06:50:23] <maximilian_h> yes, only x and y
[06:50:27] <maximilian_h> G17
[06:50:34] <maximilian_h> nothing fancy at all
[07:00:07] <Tom_itx> i'm not sure if reversing the sign of all your x y moves would give you a mirror image or not. never tried it but just thought about it
[07:01:20] <Tom_itx> and if it's a waterjet, why not just flip one over after it's cut?
[07:02:40] <Tom_itx> we often would have to make a right and left hand part to fit both wings on a plane but since everything was 3d, flipping it over just wouldn't work
[07:11:38] <maximilian_h> no, that does not work since the material is often coated or laminated on one side. In general often the material is not identical on both sides. And the cnc programs are big and use sub programs were the mirroring is switched on and off before the sub program.
[08:01:31] <jthornton> my Anilam 1100M had a mirror function
[08:06:40] <r00t4rd3d> Gas from beef and broccoli is very unpleasant.
[08:14:14] <r00t4rd3d> think ill build a torsion box for my new machine today
[08:38:07] <JAS> hello friends
[08:39:59] <JAS> i hope i can get some help here about linuxcnc
[08:40:10] <mk0> speak
[08:40:32] <jthornton> JAS, the SOP is to just ask your question
[08:40:51] <JAS> hello mk0 thx for reply
[08:41:09] <JAS> thx jthornton
[08:41:19] <mk0> no one is biting here)
[08:41:26] <jthornton> lol
[08:41:28] <mk0> like labradors
[08:42:14] <JAS> i want to ask i have succesfully used linuxcnc with stepper motors i use 3 axis
[08:42:26] <JAS> :)
[08:43:20] <JAS> now i want to use 4th axis as spindle and i want to use my spindle as servo motor
[08:43:55] <JAS> so i am cant understand what all i need to start using servo as spindle
[08:44:02] <JAS> in 4th axis
[08:44:07] <JAS> need help
[08:44:34] <JAS> i am using linux cnc 2.5.2 version
[08:45:43] <JAS> can anyone guide me to right direction :)
[08:46:19] <Jymmm> <--- RIGHT DIRECTION --->
[08:46:54] * jthornton can't wait any longer for the question and heads for the shower
[08:48:26] <JAS> i mean do i need mesa 5i25 card to run servo motor and which servo motor i should choose
[08:50:43] <JAS> i know i sound bit lost but thats why i am here
[08:51:47] <JAS> ?
[08:53:14] <alex_joni> depends on the servo motor
[08:53:19] <alex_joni> and how you want to drive it
[08:56:58] <FinboySlick> http://linuxgizmos.com/index.html Looks like a lovely little thing to me.

[10:23:03] <IchGuckLive> hi all
[11:01:01] <generic_nick> hi
[11:03:02] <generic_nick> so my z axis encoder doesnt seem to count at high rpm's. the motor runs away from time to time while tuning and the encoder doesnt count any of it. works fine at lower rpm's though.
[11:03:10] <generic_nick> time for replacement?
[11:04:02] <generic_nick> i'm gunna look and see if the shaft is loose i guess.
[11:07:42] <jdh> hooked up to mesa?
[11:08:26] <generic_nick> yes
[11:08:32] <generic_nick> 5i20/7i33
[11:09:36] <generic_nick> doesnt have to spin very fast before it stops counting. maybe 200rpm? just a wild guess.
[11:09:59] <jdh> bummer
[11:11:41] <pcw_home> might check it its contaminated/dirty
[11:13:33] <generic_nick> yea think i figured it out
[11:13:58] <generic_nick> the disk is a tad far away from the little readers in the encoder
[11:14:16] <generic_nick> i know the other one i had needed to be somewhat close
[11:14:42] <generic_nick> ill see if i can adjust it
[11:22:53] <generic_nick> nope that wasnt it
[11:23:00] <generic_nick> i think its just fubard
[11:34:19] <generic_nick> i have the same encoder on my lathe spindle
[12:08:31] <IchGuckLive> hi all B)
[12:15:40] <GammaX> morning.
[12:15:47] <IchGuckLive> hi
[12:15:52] <GammaX> anyone have a core2duo motherboard they wanna sell?
[12:15:55] <IchGuckLive> hows it over there
[12:16:20] <GammaX> good, getting ready to go test my setup... only thing im dreading is im moving my shop to accross town this weekend...
[12:16:25] <IchGuckLive> there are so cheep second it stores around
[12:17:01] <GammaX> im preparing to get the hardinge on linuxcnc soon...
[12:17:17] <GammaX> have a feeling the crusader controller is going to be on the fritz...
[12:17:25] <IchGuckLive> nice work if
[12:21:26] <Loetmichel> re @ home
[12:24:02] <L84Supper> GammaX: why the core2duo?
[12:25:51] <GammaX> L84Supper I believe my MB crapped out.... If I can just replace that... im good unless someone has a motherboard cpu combo of a diff type.
[12:28:20] <L84Supper> GammaX:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007623%20600142363&IsNodeId=1&name=AMD%20APU
[12:28:47] <GammaX> I can buy a used computer for that much lol
[12:28:49] <L84Supper> all under $80 for MB + CPU + GPU combo
[12:29:48] <GammaX> hmmm
[12:30:31] <GammaX> y u pick amd? Bleh!
[12:31:01] <L84Supper> been using mostly AMD since the 90's
[12:31:14] <GammaX> I was but then I went intel and havnt turned back..
[12:31:23] <Tuipveus> do you know some good hardware-shops for cables...
[12:31:29] <GammaX> started out with a amd athlon thunderbird 1.13 ghz...
[12:31:53] <Tuipveus> I have Atari Falcon 030 computer with scsi-2 (50 pin external) connector and harddisks with 68-pin internal connector
[12:32:13] <GammaX> wow lol
[12:32:23] <Tuipveus> this computer has been made in 1993, but I am not able to find adapter for that anymore
[12:35:37] <L84Supper> tried
http://www.cablestogo.com and similar?
[12:36:19] <L84Supper> http://www.cablestogo.com/category/pc/pc-scsi/scsi-adapters
[12:36:40] <pcw_home> GammaX the AMD fusion MBs are known to work with current (Ubuntu 10.04 based) LinuxCNC
[12:36:42] <pcw_home> and some (like the Gigabyte and ASUS) are know to have good latency. Intel Mini ITX offerings
[12:36:43] <pcw_home> based on the latest Atoms all have video issues (at least there no decent driver support)
[12:40:19] <GammaX> pcw_home I just wanna stick with the cheapest thing. and since I already have a proc then All I need is a cheapo 20 dollar MB
[12:41:01] <GammaX> http://www.ebay.com/itm/ASRock-775i945GZ-Socket-775-Core2-Duo-Motherboard-945GZ-ICH7-w-Onboard-Video-/230933789210?pt=Motherboards&hash=item35c4b9fa1a
[12:41:23] <L84Supper> PREEMPT RT! 6,417ns jitter on servo thread, 10,232ns jitter on base on a 3-4 core Phenom, and 780 or 880 chipset
[12:41:36] <pcw_home> 775 MBs should be common as dirt
[12:41:58] <GammaX> 30 bucks with onboard video
[12:42:21] <L84Supper> with tired core voltage caps
[12:42:50] <zultron> Nice numbers.
[12:42:57] <pcw_home> Thats pretty amazing for PreEmptRT
[12:43:08] <zultron> amazing indeed.
[12:43:32] <L84Supper> he's still working on kernel configs
[12:43:36] <zultron> Gives me hope for packaging LinuxCNC for Fedora. :)
[12:44:21] <L84Supper> something with kinematics needs to get sorted out as well
[12:44:42] <pcw_home> maybe at some point enough brute horsepower and fast busses win
[12:44:43] <zultron> Maybe folks will have a viable distro package with a more-or-less supported RT kernel.
[12:45:17] <GammaX> http://www.ebay.com/itm/ASRock-ConRoeXfire-eSATA2-Socket-775-Core2-Duo-Extreme-Motherboard-945P-ICH7R-/310606957107?pt=Motherboards&hash=item48519e0a33 28.50! I have my own graphics card...
[12:46:21] <L84Supper> was with a Phenom II X3 720 (2.8GHz)
[12:49:06] <generic_nick> yay, you have 7i48's in stock.
[12:50:17] <generic_nick> oh that reminds me, i have a spare atom pc from the old mill i was going to build. what to do with it....
[12:50:28] <GammaX> I was thinkin of buying the 6i25 in anticipation for the hardinge conversion...
[12:50:42] <GammaX> generic_nick Ill take it :D
[12:50:57] <generic_nick> ha.
[12:51:04] <generic_nick> i was thinking htpc
[12:51:13] <generic_nick> what's the 6i25?
[12:51:50] <generic_nick> nm, found it
[12:52:54] <GammaX> yerah the combo is only 225 os so
[12:54:29] <Tuipveus> hmm... I will try to search
[12:54:51] <Tuipveus> ebay just gives me tons of cables with internal 50 connector, not external
[12:55:07] <generic_nick> i use a 5i20, 7i33, 7i37, and 7i42 in my hardinge
[12:55:26] <GammaX> damn! thats a whole mess ofmoney
[12:55:31] <GammaX> those cards a re alot ofmoney
[12:57:40] <generic_nick> it's all relative
[12:57:54] <generic_nick> it's still cheap for a cnc lathe with a toolchanger
[12:58:23] <GammaX> .... correct!
[12:58:32] <generic_nick> i may have $2500 into it. i think that's cheap for what it is.
[12:59:36] <Tuipveus> that is what I need, but 50 connector should be male, not female....
http://www.cablestogo.com/product/13192
[13:01:59] <andypugh> Tuipveus: Might be easier to make up a custom cable.
[13:02:26] <Tuipveus> http://www.cablestogo.com/product/08176
[13:02:35] <Tuipveus> that is what I need... but quite expencive :)
[13:03:25] <Tuipveus> maybe I just stick to my ide 2.5"
[13:04:38] <andypugh> How about
http://www.ebay.com/itm//230471197301
[13:05:54] <GammaX> http://www.techxtend.com/PPI_US/Product.aspx?sku=ZHI%20709918&source=WEBGSHOP&gclid=CKvbprKt4bYCFZBcMgodA2wAfw
[13:06:19] <GammaX> andypugh nice find lol
[13:09:09] <L84Supper> funny how some people never throw anything away
[13:09:42] <L84Supper> hoarder or good businessperson?
[13:10:06] <Tuipveus> I got some adapter from work from different computers... but I am not sure if pin-order is right
[13:10:07] <GammaX> hoarder
[13:10:26] <Tuipveus> I am a bit afraid trying and breaking anything
[13:11:09] <Tuipveus> andypugh: yeah, that is much more reasonable price... if connectors are ok
[13:11:38] <GammaX> anyone know a good source for a chinese clone tormach power draw bar cylinder?
[13:11:38] <L84Supper> Tuipveus: just be safe, get one of these
http://www.paralanstore.net/index.php?main_page=product_info&cPath=11&products_id=55
[13:11:46] <Tuipveus> description matches
[13:12:15] <Tuipveus> L84Supper: haha
[13:12:38] <L84Supper> or a $10 multimeter
[13:15:21] <Tuipveus> yes... but multimeter does not have all those cool leds! :)
[13:17:24] <GammaX> the tormach loooks just like a better built rf45...
[13:17:39] <ssi> got my 5i25/7i77 kit
[13:27:01] <IchGuckLive> By
[13:29:02] <L84Supper> andypugh:
https://www.youtube.com/watch?NR=1&feature=endscreen&v=95B8PDlnajk did you start with a complete mini-lathe-mill or did you add the mill to a lathe?
[13:30:18] <andypugh> It was like that from the factory.
[13:30:32] <L84Supper> https://www.youtube.com/watch?v=ZhICrb0Tbn4 somebody was asking about its weight the other day
[13:30:33] <andypugh> FWIW, a lathe saddle amkes a rather poor milling table.
[13:30:40] <GammaX> you guys using a fixture for tapping on your mills?
[13:30:55] <Loetmichel> andypugh: not really the right tool for pcb drilling... maybe get a speed up gear?
[13:31:36] <andypugh> I don't do much PCB drilling any more, I mainly use SMT and have the boards made for me (as Seeed is so cheap)
[13:32:02] <andypugh> GammaX: I think most of us use rigid tapping, mainly to taunt Mach3 users.
[13:33:02] <Loetmichel> GammaX: i tap with an battery screwdriver. or with the hand tool holder and a bit of muscle when the tapping bit is bigger than 8mm
[13:33:34] <L84Supper> mach3 could rigid tap if they wanted to, they are just busy with some other stuff :)
[13:33:36] <andypugh> Ah, yes, I also often use the cordless drill :-)
[13:33:42] <Tom_itx> andypugh or anybody else: the comments i made earlier about making a mirror image for a 2d flat patern... would it work by changing the sign on the x and y axis movements?
[13:33:49] <GammaX> andypugh is it as affective as a holder/tool?
[13:34:12] <jdh> the clutch slipping on the cordless drill seems to help tapping also
[13:34:26] <andypugh> Tom_itx: reversing any one axis ought to work.
[13:34:36] <archivist> 3mm taps die in a cordless drill!
[13:34:37] <Tom_itx> i realize that wouldn't work for a 3d profile
[13:35:11] <andypugh> Tom_itx: It ought to work for 3D too.
[13:35:22] <Tom_itx> the editor that came with my cad cam will do stuff like that pretty easy
[13:35:39] <Tom_itx> someone was asking about mirror image G codes earlier this morning
[13:35:55] <GammaX> anyone recomend a tool touch off?
[13:36:17] <jdh> I thoguht he really wanted to swap x/y, not so much mirror?
[13:36:28] <Tom_itx> he wanted a mirror image
[13:36:44] <Tom_itx> and
[13:36:52] <andypugh> If he wants to rotate around Z (which is the same as an XY swap) then G10 R90 is the way to do it.
[13:36:54] <L84Supper> how come only 10-32 taps break in aluminum? :) no other size breaks half way into the last hole in a project
[13:37:22] <Tom_itx> on a water jet i suggested just making two parts and flipping one over but he came back with the fact that the material isn't the same on both sides
[13:37:23] <andypugh> L84Supper: Just glue a bolt head over that hole.
[13:37:45] <Tom_itx> andypugh, it's on a waterjet
[13:37:57] <frallzor> GammaX expensive machine?
[13:38:04] <andypugh> Tom_itx: So? G10 R90 stilll works.
[13:38:08] <Tom_itx> ok
[13:38:14] <Tom_itx> i've never messed with that
[13:38:20] <GammaX> frallzor pm45cnc
[13:38:40] <frallzor> dont know that =)
[13:38:47] <GammaX> rf45 clone of some type
[13:39:49] <frallzor> http://www.cnc-plus.de/product_info.php?language=en&gm_boosted_product=-1467&products_id=1467& got one of those for my MechMate
[13:40:09] <frallzor> works pretty ok, just as long as you got the tools to measure when it triggers
[13:40:14] <GammaX> one thing I should have asked yesterday... how do I hook this bad boy up since my drives only take 4 wires...
http://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/12/KL342120-42-8A-KEY.pdf ? THanks!
[13:40:43] <GammaX> frallzor that looks real nice!
[13:41:12] <frallzor> i got the bit thicker one though, but same stuffs, just smaller size
[13:41:28] <andypugh> Tom_itx: he probably needs:
http://code.google.com/p/grecode/
[13:42:17] <Tom_itx> we had a Fadal that used G50.1 and G51.1 for mirror image
[13:42:17] <jdh> <maximilian_h> so I cannot apply grecode to the whole program :(
[13:42:26] <jdh> that's when I left
[13:42:31] <Tom_itx> but the cutter paths would cut backwards
[13:42:48] <L84Supper> GammaX: they show you the 3 choices on the drawing
[13:43:18] <Tom_itx> and i didn't see a similar code for lcnc
[13:43:21] <Tom_itx> as the fadal
[13:43:23] <GammaX> L84Supper yeah i dont know which one to use lol
[13:45:09] <GammaX> L84Supper taking a 2nd look im assuming bipolar series...
[13:45:36] <GammaX> blue and red together would go to a+ yellow green goes to a-
[13:45:50] <L84Supper> where is a good tutorial on Bipolar series/parallel vs unipolar on steppers?

[13:47:29] <Tom_itx> http://homepage.cs.uiowa.edu/~jones/step/index.html
[13:48:56] <Tom_itx> i'm pretty sure i wired mine parallel bipolar
[13:49:04] <Tom_itx> on those hybrid motors
[13:49:38] <GammaX> based on the torque-speed pic im lookin at parallel bipolar would be best...
[13:50:11] <GammaX> although amps will go up by 1.4
[13:50:23] <GammaX> X 1.4
[13:50:39] <Tom_itx> i can afford a couple amps
[13:50:51] <GammaX> I prolly shoulda gotten a diff PS
[13:51:10] <Tom_itx> if your supply won't hack it, wire them differently
[13:51:27] <L84Supper> that connection has the lowest inductance so it's faster but draws more current
[13:51:30] <Tom_itx> i tried to make sure mine would
[13:51:40] <GammaX> wait it should actually
[13:51:54] <GammaX> it says 6 amps per phase in bipolar parallel..
[13:54:33] <GammaX> if its 6amps per phase... does that mean my one 34 would be pulling 12 amps?
[13:54:37] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/Step_Motor_Basics_Guide.pdf
[13:55:46] <Tom_itx> 6
[13:56:03] <GammaX> Tom_itx 1 stepper = 1phase?
[13:56:13] <Tom_itx> are they both active at once?
[13:56:28] <GammaX> ahhhh
[13:56:36] <GammaX> good call
[13:57:04] <Tom_itx> mine are 4.2/phase in bipolar parallel
[13:57:08] <andypugh> Why can't he use grecode on the whole programme?
[13:57:14] <Tom_itx> no idea
[13:57:46] <andypugh> OK, where can I get a spiral cable suitable for mains voltage and 1 amp?

[14:04:07] <Tom_itx> andypugh, an old hairdryer
[14:06:25] <Tuipveus> I bought that cable, thanks for the tip
[14:06:44] <L84Supper> http://us.misumi-ec.com/us/ItemDetail/10300135740.html using this with a screw to lock it, has anyone seen something similar only like a micrometer for really fine positioning
[14:07:01] <Tuipveus> but didn't buy the tester :)
[14:07:47] <Tom_itx> L84Supper mcmaster makes cam locks
[14:07:51] <Tom_itx> err sells
[14:07:59] <andypugh> I found a light fitting to cannibalise
[14:08:18] <Tom_itx> the plexar lamp?
[14:08:40] <andypugh> something on ebay
[14:09:56] <archivist> andypugh, wind wire around a bar tightly, put in an oven for a while, bingo
[14:11:16] <andypugh> the light fitting has the spring counterbalance too.
[14:12:10] <Tom_itx> electric razors are usually coiled too
[14:12:44] <archivist> wtf is a razor?
[14:13:47] <andypugh> I am not sure. I think I have heard of them.
[14:14:39] <archivist> I would have to go back 40 odd years

[15:17:01] <mrsun> i upload them there anyhow for my friends to see :P
[15:17:11] <Tom_itx> one day it's 70f now it's gonna freeze overnite
[15:18:25] <frallzor> I like imageshack
[15:26:44] <Tom_itx> is that for a plasma cutter or what?
[15:28:24] <frallzor> its his own version of a mechmate
[15:32:25] <mrsun> :P
[15:33:11] <mrsun> Tom_itx, time will tell, if it doesnt do routing it will do plasma :P
[15:33:18] <mrsun> i need both so hell =)
[15:33:20] <frallzor> Hmm I want to machine something but what....

[15:59:46] <JesusAlos> which CAM sofware we need for that?
[16:13:03] <r00t4rd3d> A lantern I made:
http://i.imgur.com/VDKj4W0.jpg
[16:13:34] <frallzor> its not green!
[16:13:54] <r00t4rd3d> the frame is
[16:14:05] <r00t4rd3d> cant see it though in that dark pic
[16:14:23] <mrsun> hmm running two steppers on the same driver .. does that work good? ... im thinking the start of the drivers they jump to the closest whole step it seems and if one of them is a bit off fromt he other they might jump 1 step off from eachother? :/
[16:14:23] <frallzor> although I cant tell since the picture is dark
[16:14:48] <frallzor> works good if you have a easy driven machine
[16:14:49] <frallzor> so no
[16:15:00] <frallzor> but never a good idea
[16:15:09] <frallzor> better use 2 drivers connected to same axis
[16:16:00] <mrsun> thinking if i have to have drive on both sides of the gantry or not .. if it works aight with one its fine ...
[16:16:28] <mrsun> as big jerks kinda throws it of a bit .. tho i have no underside support bearings on the thingies yet :P

[16:30:28] <r00t4rd3d> the engine compartment saved his ass
[16:33:06] <andypugh> mrsun: If you do run two steppers from the same driver I think they would need to be wired in series.
[16:40:11] <JesusAlos> gn8
[16:51:22] <mrsun> gonna try with single side drive and see how it goes :P
[17:38:44] <mpictor> anyone on here using RTNET / Mesa 7i80 with an rtl8101/rtl8102 NIC?
[17:39:11] <mpictor> it works with the standard r8169 driver, but hangs with the realtime 8169 driver
[17:43:44] <andypugh> mpictor: I think you will need to wait until micges is online.
[17:49:18] <mpictor> k
[18:18:15] <generic_nick> well i got my y axis working good. the x axis motor kind of sucked so i am swapping it with another one that seems to work fine.
[18:18:50] <generic_nick> z axis encoder was bad, but i found another one locally and ill be picking that up in a bit. hopefully itll be running tonight!
[18:23:59] <generic_nick> getting some decent acceleration on the y axis.
[19:04:36] <r00t4rd3d> i took more pics of my lantern:

[19:12:21] <r00t4rd3d> logo,icon,whatever
[19:25:34] <andypugh> Interesting device, badly advertised. It's a semi-universal lathe, with a rise-and-fall carriage.

[19:29:58] <failsafe247> hey guys anyone wanna give me a rundown on the current state of the modbus lib?
[19:30:23] <failsafe247> I wanna control my Hitachi wj200 VFD using a serial to RS485 adapter
[19:30:39] <failsafe247> which I already have all wired up nice and neat
[19:31:14] <failsafe247> I saw the wiki article. I also saw the libmodbus3 discussion
[19:31:57] <andypugh> I thought it was working, but I have never tried to use it.
[19:32:23] <failsafe247> FYI, I am using the Xenomia preview3-merged-into-master version of linuxcnc. Therefore, it should be just like regular "master" branch
[19:33:29] <failsafe247> The version on the wiki probably does work, I just wanted to know if there were any "gotchas" I should know about before hand. Also, it seems there has been some recent develpoment around libmodbus3
[19:34:29] <failsafe247> I am just kinda tired working on getting my cnc router up and running 100%. Its been a bit of a draining experience
[19:35:49] <andypugh> You might do better on the mailing list, I suspect that there is likely to be nobody on here right now, and paying attention, who knows anything.
[19:36:02] <failsafe247> ha, thanks andy
[19:37:53] <failsafe247> I will attempt it using the steps on the wiki first then. If (I mean when) I run into trouble I'll post to the mailing list.
[20:16:50] <PetefromTn> ...
[20:29:48] <generic_nick> on analog brushed dc drives, where do you guys normally set the gain on the drive itself? im finding if the drive is tuned then the pid tuning in emc2 has to be set too low to be effective
[20:30:23] <generic_nick> ive been backing off the gain on the amp somewhat and raising the values in emc. seems to help, but not sure if that's right
[20:31:15] <generic_nick> almost got my x axis tuned
[20:39:50] <gamma-x> I think you will all be happy to know.. I got my x axis moving :)
[20:41:12] <Tom_itx> not as happy as you but... yes
[20:41:34] <gamma-x> lol
[20:45:44] <Tom_itx> did you stick with the suggested settings?
[20:48:58] <gamma-x> for the most part
[20:49:14] <gamma-x> only thing I need to get down furhter is acceleration/velocity etc..
[21:01:36] <r00t4rd3d> fuhrer
[21:13:17] <Connor> okay, so, question: How do you set LinuxCNC up so that it'll index the spindle to a specific position. (Nothing that it has a encoder with index..) Doing some preliminary configurations for PetefromTn machine using mine as a test bed..
[21:15:35] <PetefromTn> Connor: Dude you are MY HERO.... You're a Giant among men.....When you walk down the street, people get out of your way.... Oh and you are alright in my book LOL....
[21:15:54] <Connor> It's getting deep in here... .
[21:16:04] <Connor> :)
[21:16:45] <PetefromTn> Hells yeah it is....;)
[21:17:04] <Tom_itx> i'd say you use the index signal from the encoder
[21:17:13] <Tom_itx> that's what it's for
[21:17:35] <Tom_itx> then if you need to move it, count encoder ticks
[21:17:35] <Connor> Tom_itx: I know that.. I'm more trying to find out the specifics...
[21:18:01] <Connor> But, since it's a spindle and not a axis.. I'm not sure how that's done.
[21:18:47] <Tom_itx> there is a 'spindle-index-enable pin
[21:18:56] <Tom_itx> signal.
[21:20:47] <Tom_itx> also spindle-request and spindle-toggle signals
[21:20:55] <Tom_itx> dunno what they're for just yet
[21:22:10] <Tom_itx> encoder.xx.position-latched
[21:22:23] <Tom_itx> may have something to do with the index signal
[21:22:37] <Connor> I was thinking they're was a hal component to do this..
[21:22:40] <PetefromTn> I went to K-town today and bought the West system epoxy so I can seal up the damn coolant troughs. I will be working on them tomorrow all day. I am going to paint them with an epoxy based industrial paint that is waterproof.
[21:22:54] <Connor> PetefromTn: Cool deal.
[21:23:08] <PetefromTn> yeah man hope it works..
[21:23:18] <Tom_itx> degrease them well first
[21:24:05] <skunkworks> http://www.youtube.com/watch?v=nUKGK1BFH_A&feature=youtu.be
[21:24:24] <PetefromTn> Actually gonna wire brush the crap out of them and then wipe them down with acetone....
[21:25:31] <Connor> skunkworks: Is they're a orient hal component? if so, you know where the docs are for it ?
[21:26:27] <Tom_L> http://www.linuxcnc.org/docs/html/hal/rtcomps.html#sec:Encoder
[21:27:14] <Connor> Tom_L ?
[21:27:36] <Tom_itx> that's all i've found so far
[21:29:39] <Connor> I found a manual entry for it...
[21:29:59] <Connor> man orient on a 2.6 version
[21:30:45] <Tom_L> http://www.linuxcnc.org/docs/html/man/man9/orient.9.html
[21:31:03] <Connor> Yup.. now to find a example of how it's used...
[21:31:16] <Tom_itx> write your own example
[21:32:47] <skunkworks> Connor: there are a few examples on the forum..
[21:32:53] <skunkworks> search for orient
[21:32:56] <Connor> I'm looking...
[21:33:09] <skunkworks> again - about 12 ways to skin the cat
[21:33:30] <Connor> okay.. back in a bit.
[21:33:32] <PetefromTn> lotsa cat skinnin' going on in here...
[21:34:22] <skunkworks> http://www.linuxcnc.org/index.php/english/forum/10-advanced-configuration/26073-spindle-orientation?start=10#31135
[21:37:38] <Tom_itx> what's the difference between 'touchoff to workpiece' and 'touchoff to fixture' as far as setting your z zero and active tool height?
[21:38:32] <PetefromTn> just guessing here but probably would have the zero be top of fixture and the Z heights will be positive?
[21:49:32] <Tom_itx> i figured out what i needed
[21:56:44] <jdh> a bottle of tequila and one of those keno girls that can suck the chrome off a trailer hitch?
[22:32:02] <Tom_itx> latest recorded day in the year for snow in this area
[22:32:04] <Tom_itx> .
[22:32:08] <Tom_itx> it's snowing
[22:32:15] <mrsun> hmm
[22:32:32] <mrsun> a laser for steel is it working the same as a torch for cutting steel ?
[22:32:41] <mrsun> heat it with lase oxidize with oxygen ?
[22:32:51] <Tom_itx> since they started keeping records back in 1889
[23:01:57] <generic_nick> eww snow
[23:02:11] <generic_nick> screw that stuff
[23:04:27] <jdh> ,yep
[23:07:50] <generic_nick> havent seen snow in over a year
[23:11:54] <jdh> it snowed an inch or so here in feb 2012
[23:12:06] <jdh> schools shut down
[23:15:10] <generic_nick> lol
[23:15:17] <generic_nick> wheres here?
[23:16:00] <jdh> wilmington.nc.us.earth
[23:16:06] <generic_nick> ah
[23:16:23] <generic_nick> they dont get snow in nc?
[23:16:31] <jdh> sure, just not here
[23:16:42] <generic_nick> or are you more southern nc?
[23:16:47] <jdh> 80 miles west, they get snow, ice storms, etc
[23:16:55] <generic_nick> ah
[23:17:13] <jdh> south-east coast, ocean keeps it warmer
[23:18:20] <jdh> even in the winter, it's 70F+ if you go 50-70 miles east due to the gulfstream
[23:19:19] <mrsun> hmm when ordering on ebay ... i can select quantity of item i want but will there be an extra shipping cost for each quantity ?
[23:19:25] <generic_nick> yea i miss the atlantic for the warm water
[23:19:35] <jdh> mrsun: usually. check the 'shipping' tab
[23:19:49] <generic_nick> i live on the pacific now, the water is MUCH colder
[23:20:00] <mrsun> ahh
[23:20:06] <mrsun> each additional item 0.5 gpb
[23:20:15] <mrsun> so 9 gpb insted of 7 :P
[23:20:21] <mrsun> cool =)
[23:25:32] <mrsun> wtf, if i go to the user it says "currently has no items for sale" but when i search i find items he has for sale? :P
[23:26:39] <mrsun> ahh there
[23:26:47] <mrsun> if i go to ebay.co.uk i can see the stuff :P
