[00:02:33] <r00t4rd3d> would that be a waste of money?
[00:03:30] <ScribbleJ> It depends on what you want it for.
[00:03:45] <ScribbleJ> It doesn't look awesome or wonderful in any sense but it does look cheap.
[00:17:06] <Jymmm> only 1/8" bits and only 8000 RPM? If you're using that small, I *think* you would need a lot more RPM's than that. Maybe a trim router and a 1/4 to 1/8 adapter??? One example, could use a router speed control to slow it down I believe http://www.amazon.com/Bosch-PR10E-Single-Speed-Palm-Grip-Router/dp/B000ANT91S

[01:04:12] <r00t4rd3d> where is a place where people share their gcodes?
[01:27:12] <alex4nder> yoh
[02:06:04] <DJ9DJ> moin
[02:25:43] <archivist> r00t4rd3d, there are some more replies http://swingleydev.com/archive/get.php?message_id=230844&submit_thread=1#message

[05:13:07] <r00t4rd3d> archivist, did you see my link? Its a barb wire stretcher
[05:13:07] <r00t4rd3d> http://www.lehmans.com/store/USA_Made___Tools_and_Farm___Farming___Wire_Stretcher___33623?Args=
[06:25:01] <r00t4rd3d> where can i find more example gcode to play with ?
[06:25:23] <ReadError> they got an example folder
[06:26:05] <r00t4rd3d> oh yeah i forgot about that
[06:31:50] <r00t4rd3d> is there any places where people share their codes though that you know of?
[06:32:13] <ReadError> erm
[06:32:17] <ReadError> you can use pycam
[06:32:23] <ReadError> and make somethin ;)
[06:32:51] <ReadError> or i can link you to a part...
[06:34:39] <ReadError> http://dl.dropbox.com/u/76016256/CenterHub-3_Setup_FINAL3.ngc

[06:37:08] <r00t4rd3d> wtf
[06:37:22] <r00t4rd3d> http://img.chan4chan.com/img/2009-05-14/4-26-07-cnc_toaster.jpg
[06:38:04] <r00t4rd3d> google searching :)
[06:38:07] <r00t4rd3d> filetype:ngc cnc
[06:38:21] <r00t4rd3d> put that in search box
[06:39:27] <ReadError> try my part
[06:39:37] <ReadError> add 0.125 to it though
[06:39:56] <r00t4rd3d> i have no clue how to do that yet
[06:40:19] <r00t4rd3d> or scale things to my work space
[06:41:10] <r00t4rd3d> http://i.imgur.com/A71S8.jpg
[06:41:18] <r00t4rd3d> ive done that like 25 times
[06:41:38] <r00t4rd3d> 20 of those times my pencil misfired
[06:41:58] <r00t4rd3d> well my pencil mount did
[06:42:09] <ReadError> do you have a 1-2-3 block?
[06:42:13] <r00t4rd3d> tape and zip ties just dont cut it
[06:42:17] <r00t4rd3d> nope
[06:42:24] <ReadError> get a pair
[06:42:26] <ReadError> they are cheap
[06:42:28] <ReadError> and very useful
[06:42:29] <r00t4rd3d> i got a pair
[06:42:54] <r00t4rd3d> are they just 1" 2" 3" aluminum blocks?
[06:43:02] <ReadError> steel i think
[06:45:18] <r00t4rd3d> im gonna make a spring loaded pencil mount
[06:45:43] <r00t4rd3d> soon as i wake up
[06:45:54] <r00t4rd3d> about 2-3 hours from now :)
[06:49:23] <ReadError> do you have any material like a piece of metal thats 1/8" ?
[06:49:48] <r00t4rd3d> an old stop sign
[06:49:58] <ReadError> so
[06:50:00] <ReadError> basically
[06:50:06] <ReadError> you would take the 1-2-3 block
[06:50:06] <r00t4rd3d> i think its exactly an 8th
[06:50:09] <ReadError> put it on 1"
[06:50:23] <ReadError> then use a piece of 1/8th material on top
[06:50:38] <ReadError> move the pencil down till it touches it
[06:50:40] <ReadError> remove, start
[06:50:59] <ReadError> but do the touchoff @ 1"
[06:51:04] <ReadError> since if you where actually cutting
[06:51:09] <ReadError> you would just use the block
[06:51:18] <r00t4rd3d> couldnt i just make 123 blocks out of wood?
[06:51:20] <ReadError> and it would go 1/8th" below the 1"
[06:51:27] <ReadError> might not be that accurate
[06:51:38] <ReadError> they are like 11$ for 2..
[06:51:48] <r00t4rd3d> nothing i could get locally i am sure
[06:51:55] <ReadError> got mine from amazon
[06:53:41] <r00t4rd3d> http://www.ebay.com/itm/1-MATCHED-PAIR-ULTRA-PRECISION-1-2-3-BLOCKS-23-HOLES-0001-MACHINIST-123-JIG-/130700571648?pt=LH_DefaultDomain_0&hash=item1e6e5c7400
[06:54:03] <r00t4rd3d> do the holes matter?
[06:55:18] <r00t4rd3d> i wonder if harbor freight has any
[06:58:12] <r00t4rd3d> is a 1/8th the default depth?
[06:58:41] <r00t4rd3d> now if i did the 1" block thing would i have to have my paper 1" off the table?
[07:00:01] <r00t4rd3d> should i just use the piece of 1/8 metal on top of the paper on my table?
[07:00:11] <r00t4rd3d> ^ or
[07:03:51] <r00t4rd3d> this is how i been setting my pencil now, I move my X and Y to where I want to start on the paper just holding the pencil for guidance. I click start and wait for it to start moving then i click stop, tape my pencil so its touching the paper then restart :)
[07:05:06] <r00t4rd3d> i know thats not the write way but it works
[07:05:12] <r00t4rd3d> right*
[07:05:59] <ReadError> ya
[07:06:07] <ReadError> doing it my way will get you prepped for cutting
[07:06:14] <ReadError> i did it your way at first though ;)
[07:06:33] <r00t4rd3d> your way i would have to have my paper 1" off my table though right?
[07:07:24] <ReadError> well
[07:07:26] <ReadError> no
[07:07:40] <ReadError> you have the "endmill" 1" from the paper if you are cutting
[07:07:52] <ReadError> since its going to cut @ touchoff+0.125
[07:07:56] <r00t4rd3d> with the touch off
[07:08:04] <ReadError> touchoff can be anything
[07:08:14] <ReadError> i use 1" since its easy to measure using 1-2-3 blocks
[07:09:14] <r00t4rd3d> i need to make a touch plate
[07:09:29] <r00t4rd3d> i can solder and stuff and have resistors
[07:10:38] <r00t4rd3d> i pcb solder for fun :/
[07:10:52] <r00t4rd3d> but its really not
[07:15:15] <r00t4rd3d> http://forums.zentoolworks.com/download/file.php?id=315&sid=349c2b18e77d418c1839629b092d00e4&mode=view
[07:19:25] <r00t4rd3d> check this out
[07:19:27] <r00t4rd3d> http://i.imgur.com/kMBPB.jpg
[07:19:54] <r00t4rd3d> those are my dip switch settings on my driver, all still set to default of ON, I dont think thats the best settings.
[07:20:28] <r00t4rd3d> my microstep is set to 1, should I set that to 1/16?
[07:22:09] <r00t4rd3d> well wait, my motor specs say: Step Angle (degrees) : 1.8
[07:22:26] <ReadError> i use microsteps
[07:22:29] <ReadError> i think 10?
[07:27:28] <r00t4rd3d> what should i use for decay?
[07:33:12] <mrsun> if you do not need that degree of acuracy dont set to high microstepping
[07:33:19] <mrsun> i think i use 1/4 on my mill
[07:33:31] <mrsun> 800 steps per revolution with 2mm lead on screw
[07:33:38] <mrsun> thats quite a bit of accuracy just that =)
[07:34:03] <mrsun> 1/16 is just redicilous and most steps wont even move stuff :P
[07:36:17] <mrsun> 0,000625 per step .... will never ever ever get that kind of accuracy out of the mill :P
[07:36:25] <r00t4rd3d> how about decay?
[07:36:31] <mrsun> sorry that i do not know :/
[07:37:00] <mrsun> http://www.stepperworld.com/Tutorials/pgMicrostepping.htm
[07:37:04] <mrsun> a whole section on decay
[07:38:24] <TekniQue> microstepping is not really about accuracy
[07:38:28] <TekniQue> but smooth running
[07:39:38] <mrsun> from what i understand down to 1/8 or so it works realy good then the step increments get so small that in alot of the steps the torque wont be able to move the screws etc
[07:40:16] <TekniQue> correct
[07:41:32] <rott> hi, i got mesa 5i25 and 7i76 and when i boot and run dmesg i get : RTAPI: ERROR: Unexpected realtime delay on task 1 is this not for belong for me, because i got these mesa cards, or must i fix this problem first?
[07:41:43] <TekniQue> but even then, you only have full torque across full steps
[07:42:31] <r00t4rd3d> rott, try version 8.04
[07:43:21] <rott> r00t4rd3d: really, but then the software is old, or just for testing?
[07:43:31] <r00t4rd3d> you can update it if it works
[07:44:09] <r00t4rd3d> most recommendations for rtapi errors is use version 8.04
[07:44:23] <r00t4rd3d> i had one once on old motherboard
[07:45:31] <r00t4rd3d> if you try 8.04 and it works then follow this:
[07:45:32] <r00t4rd3d> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.5
[07:45:51] <r00t4rd3d> it will update emc2 to LinuxCNC 2.5
[07:46:16] <jthornton> rott, did you run the latency test?
[07:46:37] <r00t4rd3d> if he is getting rtapi errors it probably will not run
[07:46:56] <rott> jthornton: yes
[07:47:20] <r00t4rd3d> did it work?
[07:47:54] <rott> yes
[07:48:12] <rott> i also can run linuxcnc
[07:48:43] <jthornton> how long did you run it and what was the jitter?
[07:49:09] <rott> jthornton: about 10 minutes, 44000
[07:49:50] <jthornton> run for an hour
[07:50:33] <rott> ok, but what then ? i close latency test and all values are lost, funny one hour
[07:50:56] <jthornton> take a screen shot
[07:51:42] <r00t4rd3d> i just left mine at default
[07:51:48] <r00t4rd3d> 15000 or what ever
[07:52:17] <rott> i mean, i just want to run my stepper motors to see if all setup is working, it must not be perfectly timed, just see it run. So arent there any values i can tweak to a bad-value just to see it running?
[07:55:14] <rott> what values should i modify with the values get from latency-test?
[07:56:31] <mrsun> TekniQue, hmm havent you gotten that wrong ?
[07:57:04] <mrsun> you got at half a step 70.7% current in each winding so thats 141.4% current ... and that should equal to more torque then at the fulls tep =)
[07:58:07] <rott> what is the section [EMCMOT] in the .ini file?
[07:58:19] <rott> where can i find infos about these sections?
[08:02:41] <jthornton> rott, if your using a 5i25 config your not running a base thread and getting a realtime delay error means your computer is really bad... pastebin your ini and hal file
[08:03:46] <rott> jthornton: ini : http://pastebin.com/57xds4DN
[08:04:22] <rott> jthornton: hal : http://pastebin.com/BvdvXH7z
[08:05:39] <rott> i did not create these files by myself, i got them from JT-Shop , but i was said, that the mesa cards were the best supported, and then i cannot select them from the pnconf menu, hmmm
[08:08:20] <rott> jthornton: you found something?
[08:08:39] <jthornton> no, they look fine so far
[08:08:54] <jthornton> do you know how to clear dmesg?
[08:09:27] <rott> jthornton: no
[08:09:34] <jthornton> http://linuxcnc.org/docview/html/common/Linux_FAQ.html#_bootup_messages
[08:10:11] <jthornton> follow that, clear dmesg then run your config and after the error capture your dmesg to a file and pastbin that
[08:12:15] <rott> just starting linuxcnc gives this: http://pastebin.com/AYZa3AWX
[08:13:45] <r00t4rd3d> you can real time monitor dmesg
[08:14:02] <jthornton> [ 2148.762145] This time, there were 6659109 which is so anomalously
[08:14:03] <jthornton> [ 2148.762146] large that it probably signifies a problem with your
[08:14:03] <jthornton> [ 2148.762146] realtime configuration.
[08:14:11] <r00t4rd3d> tail -f /var/log/dmesg
[08:14:22] <r00t4rd3d> then run what ever and watch for new entries
[08:14:52] <jthornton> r00t4rd3d, that is cool
[08:15:08] <WillenCMD> hey guys, its been a while
[08:17:41] <jthornton> rott, is this new or old computer hardware?
[08:17:57] <WillenCMD> Anyone fimiliar with this error, "USRMOT: ERROR: command timeout"
[08:18:34] <WillenCMD> Im getting close to finishing a gui and this is an error message that scrolls down the terminal while the gui is running
[08:20:30] <micges> WillenCMD: pastebin whole output from terminal
[08:20:55] <micges> with [emc]debug = 0x7FFFFFFF
[08:25:54] <WillenCMD> does anyone know where i can find full api for linuxcnc, all i can find is halui. I have been just using the touchy program for finding them but its tedious and they aren't all in there.
[08:26:56] <Loetmichel> re @ home
[08:28:05] <micges> WillenCMD: only source code
[08:28:28] <Tom_itx> http://linuxcnc.org/docs/html/man/man3/intro.3hal.html
[08:29:55] <WillenCMD> thanks, sorry if i sound ignorant. Programming is relatively new to me and its been a huge learning process. But its fun and i ca't wait untill i get it done.
[08:30:02] <Tom_itx> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EMC_Components
[08:31:56] <WillenCMD> thanks tom!
[08:32:20] <Tom_itx> that last link is old docs
[08:33:28] <DJ9DJ> yeah, just git'ed, configured and compiled linuxcnc simulator on kubuntu 12.04
[08:33:31] <WillenCMD> yes but a great diagram! essentially the gui sends request's to emctask and emctask delegates/prioritize's when they should be executed by the motion controller
[08:46:09] <r00t4rd3d> or a samurai
[08:46:25] <r00t4rd3d> ASON CHOP!
[08:47:07] <r00t4rd3d> where the hell is pfred
[08:51:16] <rott> WillenCMD: check your ACPI settings in BIOS , that was my problem
[08:51:27] <r00t4rd3d> lol
[08:51:44] <rott> jthornton: its new hardware
[08:51:57] <r00t4rd3d> was the apci disabled or enabled in bios?
[08:52:16] <r00t4rd3d> acpi*
[08:58:57] <jthornton> rott, that is above my pay scale now sorry
[08:59:09] <rott> jthornton: what do you mean?
[08:59:27] <jthornton> I've run out of guesses
[08:59:36] <rott> jthornton: ok
[08:59:54] <jthornton> it does sound like a computer issue
[09:00:34] <jthornton> but wait I have one more guess can you run a sample config that doesn't use opengl like keystick?
[09:01:09] <jthornton> or mini or tklinuxcnc I think
[09:01:51] <rott> jthornton: sim-keystick show also RTAPI: ERROR unexpected realtime delay in task 1
[09:02:42] <rott> i will check my bios settings again, til later
[09:22:36] <andypugh> Why doesn't anywhere that is open on a Sunday sell DIN rail? I even considered buying a cheap consumer unit just for the rail...
[09:23:47] <archivist> "cheap consumer unit" never seen except when its a sale and bits are missing
[09:24:28] <archivist> I did snaffle one at B&Q the other week ready for fixing the garage electrics
[09:24:29] <andypugh> £9 for 4-way with no incomer. (MK too)
[09:25:22] <andypugh> That would have been another approach, I could have got the one i am likely to need to split-load the garage and temporarily borrowwd the DIN rail.
[09:26:29] <archivist> just hang the bits "rats nest style" till you can get a rail :)
[09:26:50] <archivist> I did not say that !
[09:26:59] <archivist> I admit nothing
[09:28:14] <andypugh> I am going to steal the bit from the PC-end, just to get the machine-end sorted out.
[09:30:27] <rott> hi, i enabled ACPI-2.0-support, ACPI-APIC support enabled, disabled C1E support, now the RTAPI unexpected error is gone
[09:32:23] <rott> now how do i "move" my steppers ? disable emergency-stop, enable manual-control, then choosing e..g. X-axis and click on + or - sign-buttons, or?
[09:33:35] <rott> when i click on the play-button, the gui is working, but not my steppers? what do i wrong?
[09:34:43] <rott> the gui also shows, "No tool" ? is this interresting?
[09:35:17] <Loetmichel> does the drivers have power (and enable if the have this pin)?
[09:35:51] <rott> Loetmichel: yes they got power, and they blink green, which means they are ready
[09:36:45] <Loetmichel> and the io-portspins are configured right?
[09:37:25] <rott> Loetmichel: i dont know, where can i check this?
[09:37:59] <Loetmichel> parallelport?
[09:38:03] <Loetmichel> or mesa?
[09:38:07] <rott> Loetmichel: mesa
[09:38:11] <Loetmichel> no idea
[09:38:20] <Loetmichel> <- lpt port user
[09:41:50] <rott> someone here with mesa 7i76 card?
[09:43:15] <andypugh> Yes, though I haven't used it for anything other than development.
[09:44:54] <rott> andypugh: do i need as minimum setup just to connect the dir+/- and step+/- signals to the stepper drives?
[09:45:37] <andypugh> Yes, you need to wire the stepgen position to the axis position outputs
[09:46:03] <andypugh> I think jt has a sample config somewhere.
[09:46:15] <andypugh> What are you using for a config?
[09:46:51] <rott> andypugh: config files from JT-Shop
[09:47:02] <andypugh> OK, ought to work then
[09:48:25] <rott> andypugh: so if i press the play-button in the linuxcnc gui, with the linuxcnc default font, it should start the stepper-motors, or?
[09:48:30] <andypugh> You have power to the 7i76 board?
[09:48:46] <andypugh> Yes, if everything is correct, then the motors should move
[09:48:46] <rott> andypugh: power over parallel port cable, nothing else
[09:49:44] <andypugh> I don't think you need field-power for the stepgens.
[09:50:08] <JT-Shop> rott: can you spin the steppers when the power button is on?
[09:50:31] <rott> JT-Shop: no
[09:50:34] <andypugh> Have a look in machine-show hal config and see if the pwmgen enables are good, and if the position-commands are moving, etc.
[09:52:33] <rott> andypugh: there is alot of stuff, where should i look, and for what should i look there?
[09:59:35] <rott> should the 7i76 in setup or operate mode?
[10:00:20] <JT-Shop> rott: does the DRO change when you jog?
[10:00:28] <JT-Shop> operate
[10:01:18] <rott> JT-Shop: what do you mean with "jog" ? pushing the + or - buttons in the manul-control panel?
[10:02:03] <JT-Shop> yes
[10:02:08] <rott> JT-Shop: if yes, then the DRO values change, but just the one that i choosed, e.g. X or Y
[10:03:27] <JT-Shop> yes only the selected axis will move with the +- keys
[10:03:56] <JT-Shop> give me a few minutes to get my 7i76 machine back on line so I can look at something
[10:05:51] <rott> JT-Shop: ok
[10:12:42] <JT-Shop> look in pins > 5i25... > encoder > 00 and put counts in the watch window
[10:13:07] <Tom_itx> cheers JT-Shop
[10:13:20] <JT-Shop> hey Tom_itx
[10:13:40] <Tom_itx> found a box online for my electronics. just hope it's big enough
[10:14:17] <rott> JT-Shop: if i unfold Pins in hal-configuration then there is: axis;axisui;hm2_5i25;iocontrol and motion ?
[10:14:43] <rott> JT-Shop: you mean in "HAL Configuration" gui, or?
[10:15:13] <JT-Shop> show hal configuration screen
[10:15:44] <JT-Shop> ...5i25 > encoder > 00 counts
[10:15:50] <rott> JT-Shop: yes, there i got no 5i25 just a hm2_5i25
[10:15:54] <JT-Shop> and spelling might be wrong
[10:16:07] <JT-Shop> or missing a bunch of letters as I'm not looking at it
[10:16:07] <rott> and inside hm2_5i25 i got no "encoder"
[10:16:29] <JT-Shop> sorry I meant stepgen
[10:16:53] * JT-Shop is thinking about the servos in his BP atm
[10:17:20] <rott> JT-Shop: ok i got it, but how do i "put counts in the watch window" ?
[10:17:58] <JT-Shop> first click on watch
[10:17:59] <rott> JT-Shop: ah, click on it, ok got it, there is: 546 hm2_5i25.0.stepgen.00.counts
[10:18:05] <JT-Shop> then the pin
[10:18:19] <JT-Shop> ok now jog the X axis and see if the count changes
[10:18:35] <rott> yes
[10:18:40] <rott> count changes
[10:18:47] <JT-Shop> now triple check your wiring
[10:19:14] <JT-Shop> we know your steppers have power but is the step and direction signal wired correctly?
[10:20:25] <Jymmm> LOL, oh gawd... Could you imagine if a stepper was wired step/step and another wired as dir/dir!!!
[10:20:29] <rott> ok, i got only wiring on TB2, if i start counting from 1 as in the manual, i got at TB2-pin2 step+; TB2-pin3 step-
[10:21:01] <JT-Shop> what kind of stepper drive do you have?
[10:21:30] <rott> JT-Shop: http://damencnc.com/en/components/motors-and-drivers/stepperdriver/200
[10:22:22] <andypugh> rott: I think pin 1 has a square PCB bad, just to make sure.
[10:22:40] <JT-Shop> how do you have the step and direction wired up?
[10:22:41] <Jymmm> s/bad/pad/
[10:24:24] <rott> JT-Shop: TB2-pin2 = step+ TB2-pin3 = step- TB2-pin4 = dir+ TB2-pin5= dir-
[10:25:09] <JT-Shop> your manual does not show the drive using differential signals
[10:25:15] <andypugh> rott: How are you wired? I confess I am not sure what the correct way to wire the differential pairs is.
[10:25:25] <JT-Shop> http://damencnc.com/files/manuals/HP5042%20UK.pdf page 6
[10:26:27] <Jymmm> rott: Do you have the "Interface card, SPS, or microcontroller" of this drive?
[10:27:49] <andypugh> Jymmm: That would be the 7i76 in this case
[10:28:03] <Jymmm> andypugh: ah
[10:29:42] <andypugh> rott: I think you want to wire the step and dir + pins (on the drives) to 5V as shown in the drive manual, then wire just the step/dir- of the 7i76 to the - side. But I would like to hear from pcw_home on this point.
[10:30:30] <Tom_itx> make sure enable is enabled also
[10:30:38] <Tom_itx> if it has one
[10:31:22] <rott> Tom_itx: that i have done, i asked there and no-5v or nothing on the enble pins means its enabled, when the green led is on
[10:31:24] <syyl_> hrhr
[10:31:29] <syyl_> https://dl.dropbox.com/u/24396704/pub/werkstatt.jpg
[10:32:05] <andypugh> I havn't seen your Shaper before
[10:32:23] <JT-Shop> syyl_: how did you make the photo?
[10:32:41] <Tom_itx> spun around really quick
[10:32:46] <syyl_> ;)
[10:32:47] <syyl_> microsoft image composite editor
[10:32:49] <syyl_> *ducks*
[10:32:53] <syyl_> ist works pretty good
[10:32:57] <JT-Shop> lol
[10:32:59] <syyl_> for a non-photo-editing-guy like me
[10:33:17] <Jymmm> That shop is way too friggin clean!
[10:33:39] <syyl_> you can work in a littered shop
[10:33:40] <syyl_> i hate it
[10:33:41] <syyl_> :P
[10:33:48] <Jymmm> I can still see white floors!
[10:34:40] <Tom_itx> i bet Jymmm's shop glows
[10:35:00] <Jymmm> And wth is that orange HF grinder near the door?! A glorified pencil sharpener?!?!?! =)
[10:35:34] <JT-Shop> rott: your manual shows the step and direction inputs to NOT be differential so as andy suggested +5 to + pins on your drive like your manual shows and you should be good to go
[10:35:42] <syyl_> that thing is about 30 years old, my father bought it back then...
[10:35:56] <Jymmm> syyl_: how well does it work?
[10:36:00] <syyl_> great
[10:36:06] <syyl_> runs smooth and silent
[10:36:08] <JT-Shop> the last calibration sticker on my surface plate is 1959
[10:36:10] <Jymmm> syyl_: is it HF?
[10:36:22] <syyl_> there is no HF in germany
[10:36:32] <Jymmm> JT-Shop: How in the hell do they annual calibrate a surface plate =)
[10:36:43] <Jymmm> syyl_: Well, I meant cheap china equiv
[10:36:59] <syyl_> it says made in germany on the sticker ;)
[10:37:06] <archivist> spot the bottle opener for teh beer
[10:37:12] <syyl_> hihi
[10:37:39] <rott> JT-Shop: andypugh: ok, then i need a power-supply to connect to the field-power of the 7i76 and the grab me there the 5v
[10:37:50] <Jymmm> oh, nm, just looks liek this http://www.harborfreight.com/3-inch-mini-tool-grinder-polisher-94071.html
[10:38:01] <syyl_> I bet its made in far east
[10:38:09] <syyl_> but back then, the quality was pretty good
[10:38:18] <syyl_> look at the old rong-fu mills from taiwan
[10:38:28] <Jymmm> cheap china knockoff of the orinal germna one maybe
[10:38:46] <andypugh> rott: Well, I think that the +/- pairs should work, they are listed as 5v 10A source/sink.
[10:39:05] <rott> JT-Shop: what step/dir from the 7i76 do i then connect to the step/dir- pins? just the step/dir- from the 7i76 and the step/dir+ left alone?
[10:39:14] <JT-Shop> rott: the step and direction +5v is pin 6 or 12 or 18 or 24 on TB2
[10:39:30] <Jymmm> archivist: Any flat edge surface is a bottle opener =)
[10:39:38] <JT-Shop> yes step/dir + pins will have no connection
[10:40:15] <JT-Shop> IIRC field power is only needed for I/O if I'm wrong then pcw_home will chime in I'm sure
[10:40:33] <ReadError> syyl_: i want to play with the welder ;)
[10:40:33] <rott> JT-Shop: ah thats good, i will wire it up :)
[10:40:35] <ReadError> looks nice
[10:40:45] <Jymmm> Tom_itx: No, but you need leggings and a machete to get to the other side of it =)
[10:42:03] <syyl_> newest addition to my shop, ReadError ;)
[10:42:06] <Jymmm> syyl_: neat photo btw =)
[10:42:09] <syyl_> :D
[10:43:17] <Jymmm> the drip pan is a nice idea.
[10:47:55] <ReadError> you do aluminum with it syyl_?
[10:48:08] <syyl_> nope, its just a DC unit
[10:48:14] <ReadError> oh
[10:48:20] <ReadError> i want one that can do aluminum
[10:48:22] <syyl_> most of the stuff i do is steel :D
[10:48:26] <ReadError> although i heard its very hard
[10:48:43] <syyl_> i have a ac/dc machine at work
[10:48:51] <syyl_> did a little aluminum with it
[10:49:05] <syyl_> its not that hard to glue the stuff together with it
[10:49:12] <Tom_itx> i don't see your rotary harmonic drive
[10:49:13] <syyl_> but a nice looking weld is another story ;)
[10:49:37] <syyl_> its hidden below the cnc mill :D
[10:49:49] <Tom_itx> you should be showing it off
[10:49:59] <syyl_> :D
[10:54:13] <rott> its alive
[10:55:41] <rott> thanks to all who helped me
[10:57:42] <jthornton> YEA
[10:58:22] <rott> thats really great
[10:59:05] * jthornton hears a nap calling my name
[11:05:41] <Jymmm> CODE WORD
[11:06:10] <rott> european football cup is calling, cu
[11:49:14] <IchGuckLive> hi all
[12:58:06] <ReadError> taig lathe any good?
[13:20:16] <andypugh> ReadError: For facing brake discs or threading oil drill pipe, no.
[13:26:53] <mrsun> my guess is that its nothing wrong with it =) a bit small maybe but =)
[13:26:58] <mrsun> and no leadscrew etc right? :)
[13:27:22] <mrsun> oh it does have one :P
[13:39:20] <syyl_> ReadError
[13:39:23] <syyl_> http://www.modelengines.info/
[13:39:37] <syyl_> look at this page, and what he makes using his taig lathe and milling machine
[13:40:08] <syyl_> http://lathes.jrbentley.com/taig.html
[13:40:15] <syyl_> i belive, for its size, its a good machine
[13:40:24] <syyl_> almost a small watchmakers lathe
[13:42:16] <archivist> I see rounded edges from polishing :)
[13:45:18] <syyl_> ;)
[13:45:44] <ReadError> oh nice
[13:46:03] <ReadError> seems like a good size for what i will be doing
[13:46:05] <archivist> there be skill in polishing and keeping square edges
[13:46:38] <syyl_> everybody can push a piece of metal against a polishing wheel :D
[13:46:47] <syyl_> but a good polishing job takes real skill :D
[13:47:17] <ReadError> http://lathes.jrbentley.com/AboveHeadstock01.jpg
[13:47:23] <archivist> pivot file ftw
[13:47:24] <ReadError> that a powerfeed ?
[13:47:30] <syyl_> yeah
[13:48:03] <syyl_> archivist: thats a watchmakers way to polish pins, right?
[13:48:22] <archivist> and clock makers
[13:49:46] <alex4nder> sup
[13:51:21] <alex4nder> ReadError: you looking at picking up a lathe?
[13:51:49] <archivist> syyl_, he uses a pivot file then a burnisher http://www.youtube.com/watch?v=1s-VVfda1ns
[13:52:26] <archivist> but he fails to show the mirror finish you can get
[13:56:50] <ReadError> alex4nder: yea here in a bit
[13:57:15] <ReadError> the taig looks affordable
[14:26:40] <alex4nder> ReadError: you thought about just using your mill as a lathe/
[14:26:44] <alex4nder> since it's already CNC
[14:28:49] <Jymmm> are the "belts" on that just o-rings?
[14:29:12] <alex4nder> belts on what?
[14:30:26] <Jymmm> the thing ReadError LINKED TO
[14:30:50] <archivist> I would say yes
[14:31:00] <DJ9DJ> re
[14:31:07] <Jymmm> is that common place?
[14:31:35] <alex4nder> Jymmm: oh, you mean the thing I had to backscroll to figure out what you were talking about?
[14:31:48] <Jymmm> alex4nder: yes you lazy bastard
[14:32:01] <Jymmm> =)
[14:32:05] <alex4nder> yah
[14:32:37] <Jymmm> Ok, just wans't sure if anyone used like fiber belts for that kinda thing or not.
[14:32:44] <Jymmm> fiber enforced
[14:32:45] <alex4nder> the taig does by default
[14:32:49] <alex4nder> that's not 'stock'
[14:33:17] <Jymmm> Just seems easy enough to keep a few on hand as needed.
[14:33:36] <andypugh> Does it do threading? I suspect not?
[14:34:18] <Jymmm> could you if you used a stepper and toothed belt?
[14:34:23] <ReadError> alex4nder: I dont want to deal with switching it back and forth
[14:35:34] <alex4nder> ReadError: maybe we have different ideas.. I'm talking about buying the Taig lathe spindle and (if you must) motor, and mounting that to the mill bed.
[14:35:53] <ReadError> they are so cheap though
[14:36:07] <alex4nder> yah, but if you use your mill, you get an instant CNC lathe
[14:36:51] <alex4nder> I want a lathe, so I've been looking at CNC options
[16:00:36] <sendoushi> hey guys
[16:00:59] <sendoushi> i'm completely newbie on cnc theme.
[16:01:31] <sendoushi> i know something about electronics. i'm thinking on building a CNC to build essentially guitars. I need some advice. Can anyone help?
[16:02:25] <archivist> in irc ask the real question not if we can help
[16:03:01] <sendoushi> so... I want to make a cheap CNC (for now)
[16:03:07] <archivist> none of us know if we cam help till we see the question!
[16:03:14] <archivist> can
[16:03:24] <sendoushi> i guess that precision and quality counts on this cheap factor and I can always get some hand job on the final cnc work
[16:03:35] <sendoushi> so... for now i'm checking this tutorial: http://www.instructables.com/id/How-to-Make-a-Three-Axis-CNC-Machine-Cheaply-and-/
[16:03:51] <sendoushi> i'm wondering around electronics and software
[16:03:59] <DJ9DJ> gn8
[16:04:11] <sendoushi> first of all... does linuxcnc work with solidworks or some 3d software ?
[16:05:31] <archivist> you wanted cheap and you mention solidworks!
[16:05:56] <sendoushi> archivist: already have solidworks and autocad on my brother's computer since he works all day long with those softwares
[16:06:15] <sendoushi> so the cost of that software: 0
[16:06:53] <archivist> do you have its cam module/addon
[16:07:03] <sendoushi> i guess not
[16:07:13] <sendoushi> he works with a professional CNC
[16:07:22] <sendoushi> i dunno if that matters...
[16:07:30] <sendoushi> i don't even know how he sends the data to the CNC in fact
[16:07:54] <archivist> via some sort of cam or handwriting the gcode
[16:08:13] <sendoushi> naaaa he doesn't handwrite that's for sure. he can't
[16:08:34] <sendoushi> so from what i getting on this... i have to get a CAM export
[16:08:43] <sendoushi> from there I can use whatever software I want that's it?
[16:09:07] <archivist> or sends the model and some other person with the cnc is doing the cam
[16:09:49] <sendoushi> archivist: i know that he is the only guy doing that and i've seen him building on some software which i dont remember if autocad or solidworks and then sends to the machine
[16:10:23] <sendoushi> but anyhow... the thing is, i have to export to CAM that's the only requirement on any software i choose is that it?
[16:11:54] <archivist> I dont do yes/no answers, its never that simple
[16:12:06] <sendoushi> ok.
[16:12:27] <sendoushi> let's put this way, linuxcnc for example reads CAM?
[16:13:33] <archivist> no it read gcode
[16:13:37] <archivist> reads
[16:13:50] <sendoushi> ok
[16:13:57] <sendoushi> now... about the electronics
[16:14:12] <sendoushi> which drivers should I use, which motors... ?
[16:14:22] <sendoushi> ideas?
[16:14:28] <archivist> cad->cam->postprocessor->gcode->machine control
[16:14:45] <sendoushi> ah ok thanks
[16:15:19] <archivist> cam is a huge bag of worms that depends on what you wish to make
[16:16:40] <sendoushi> i'll search more about that
[16:17:29] <sendoushi> about the other question...
[16:17:31] <sendoushi> which drivers should I use, which motors... ?
[16:17:51] <micges> how much money do you have?
[16:18:02] <sendoushi> less than you expect :D
[16:18:19] <sendoushi> let's say that I want to keep this cheap
[16:18:26] <sendoushi> i have a dremel which i want to use as router
[16:18:40] <sendoushi> i dont care about time of cncing
[16:18:48] <micges> ok
[16:18:52] <archivist> make your drivers yourself then
[16:18:57] <sendoushi> for now precision is not really really the issue since i can finish by hand some parts
[16:19:11] <sendoushi> archivist: isnt that too much for a newbie electronics guy?
[16:19:19] <sendoushi> i know about electronics but not really that much and then...
[16:19:39] <sendoushi> it depends on the difference!
[16:19:49] <micges> you want cut guitars corps and then finish by hand?
[16:20:06] <sendoushi> i can do that... if the cnc does everything hey... wonderful!!!
[16:20:09] <archivist> one of the cheap ebay stepper drivers is next up
[16:20:16] <sendoushi> but if it doesnt and i get like a 200e discount...
[16:20:39] <sendoushi> archivist: so you say to search for those cheap ebay stepper drivers?
[16:20:48] <archivist> but they are weedy and you want to drive a large router
[16:21:09] <sendoushi> so... what's your advice?
[16:21:27] <archivist> something like the longshine drivers
[16:21:46] <archivist> come with many names stuck on them
[16:22:18] <sendoushi> am... not wanting to be a pain in the ass.. what should i search for?
[16:23:26] <sendoushi> searched longshine drivers and... didnt get there
[16:24:55] <archivist> if you search for stepper drivers a lot look like http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors/Stepper-Drivers
[16:25:31] <sendoushi> are those the one you advice to?
[16:25:32] <archivist> most if not all that look like that are probably longshine
[16:25:43] <sendoushi> ah ok ok
[16:25:48] <archivist> I happen to use those
[16:25:55] <sendoushi> awesome.
[16:26:07] <sendoushi> let's say i use those. what motors? nema 17?
[16:26:19] <sendoushi> cheaper ones?
[16:26:23] <archivist> others prefer gecko drivers but they cost a bit more
[16:27:12] <sendoushi> those work right?
[16:31:18] <sendoushi> hm?
[16:31:33] <archivist> there are many solutions, they all work one way or another, this advice is worth what it costs :)
[16:32:20] <joe9> sendoushi: i use freecad and heekscnc
[16:32:37] <joe9> i have not been following the discussion, so, please excuse me if this is off-topic.
[16:32:55] <joe9> with freecad, you can basically code in python and generate the figures
[16:34:15] <sendoushi> joe9: here is the thing i'm thinking on building a mill cnc
[16:34:21] <joe9> http://codepad.org/yQJABQBe
[16:34:27] <joe9> check this out.
[16:34:36] <sendoushi> with main objective to build guitars but I can use it for other things
[16:34:41] <joe9> sendoushi: go with a taig. check with alex4nder and ReadError for more details
[16:34:49] <sendoushi> taig?
[16:34:52] <ReadError> if you want to make guitars
[16:34:56] <ReadError> you will need a router table
[16:35:04] <archivist> taig would be too small for his application
[16:35:35] <sendoushi> http://www.instructables.com/id/How-to-Make-a-Three-Axis-CNC-Machine-Cheaply-and-/ this is the tutorial i'm thinking on
[16:35:53] <sendoushi> for thos crashing into the topic
[16:36:02] <ReadError> sendoushi: ask r00t4rd3d when he gets back
[16:36:09] <ReadError> he just built one
[16:36:22] <archivist> I think a dremel is a bit on the tiny side for one of those
[16:36:30] <ReadError> <r00t4rd3d> My entire build : http://imgur.com/a/Kupuo
[16:36:37] <joe9> ReadError: do you have the model number of the milling bits we ordered?
[16:36:43] <sendoushi> archivist: tiny? a lot of people is using it
[16:37:32] <joe9> EM2E8-0625-90V 90° "V" point, PreciseBIT 2-flute Scoring / Engraving bit, 0.005in tip web,1.42 in. (36mm) OAL
[16:37:33] <sendoushi> ReadError: interesting build
[16:37:39] <joe9> ReadError: is it the above bit?
[16:37:39] <archivist> sendoushi, using and being successful I ask myself, yes I do use dremels a lot but not that way
[16:37:44] <ReadError> EM2E8-0625-90VC
[16:37:53] <joe9> ReadError: thanks.
[16:38:01] <sendoushi> archivist: a real router is kind of expensive... for now
[16:38:25] <archivist> you can homebrew a better spindle
[16:38:37] <sendoushi> can i?
[16:38:47] <sendoushi> don't forget my lack of experience ehehe
[16:38:54] <sendoushi> and knowledge
[16:39:48] <archivist> I have not tried this but looks a good start http://www.raynerd.co.uk/?p=1562
[16:40:37] <archivist> I have no idea how reliable those motors are
[16:40:51] <sendoushi> is that homebrew?
[16:41:10] <sendoushi> i dont see myself constructing something like that
[16:41:31] <sendoushi> and since i already have a dremel...
[16:41:37] <Jymmm> 100A ?!
[16:41:40] <sendoushi> cost-wise... for now... maybe its the best option
[16:44:10] <sendoushi> what about motors?
[16:44:19] <sendoushi> which do you tell me to use?
[16:45:12] <archivist> ones large enough for your machine, or you need to add gearing
[16:45:40] <sendoushi> when you say large enough you say large enough to move the "platforms" ?
[16:47:58] <sendoushi> is it hard to build my own step drivers?
[16:48:23] <sendoushi> is the difference between a diy and an already made one money-wise significant?
[16:48:38] <joe9> proxxon ib/e is supposed to be the industrial version of dremel, if that helps.
[16:49:08] <joe9> sendoushi: dremel is considered to have a lot of runout
[16:49:21] <joe9> and not of much use for accuracy/precision.
[16:49:56] <sendoushi> joe9: hmm... for now, i'm more worried about the electronics. the motors, the drivers...
[16:50:10] <sendoushi> where i'll get the bearings and rods and stuff
[16:50:15] <sendoushi> how i'll do all this eheh
[16:50:20] <sendoushi> especially the electronics
[16:50:36] <joe9> gecko?
[16:50:40] <archivist> worried! get making something soon you will gain knowledge
[16:51:08] <Jymmm> sendoushi: the electronics is the easy part =)
[16:51:32] <sendoushi> is it?
[16:51:40] <Jymmm> yeah
[16:51:52] <sendoushi> what would be the difficult part then?
[16:51:57] <Jymmm> mechanical
[16:52:16] <Jymmm> or at least getting the mechanical properly =)
[16:52:33] <sendoushi> for that i have the instructables tutorial no?
[16:52:40] <sendoushi> they already have the plans and all
[16:52:44] <Jymmm> and the electonics, I should say is the easiest part.
[16:54:16] <sendoushi> http://www.ebay.es/itm/Cnc-1-7A-12-36VDC-128Micostep-Bipolar-CNC-digital-Wantai-stepper-motor-driver-/170829137223?pt=LH_DefaultDomain_0&hash=item27c635c547 is this only for one motor?
[16:55:29] <archivist> yes one per stepper motor needed
[16:56:34] <sendoushi> that's kind of expensive
[16:56:36] <sendoushi> one per motor
[16:56:39] <sendoushi> that's like 100e only for the drivers
[16:57:05] <sendoushi> 75e
[16:57:22] <sendoushi> http://www.ebay.es/itm/CNC-Stepper-Motor-Driver-5-Axis-Interface-Board-adapter-/220943639367?pt=LH_DefaultDomain_77&hash=item3371446347 are these so awful?
[16:58:49] <ReadError> its not cheap ;)
[16:58:53] <ReadError> (cnc)
[16:59:17] <sendoushi> it really isnt it really isnt
[16:59:24] <sendoushi> but i want to keep these things cheap for now
[17:00:06] <sendoushi> and then if everything goes nicely and if i even sell something with it
[17:00:09] <sendoushi> maybe a guitar ehehe
[17:00:17] <sendoushi> hey... on that time i should step a level
[17:00:32] <archivist> that board drives the stepper drivers
[17:00:58] <archivist> it is a break out board
[17:01:30] <Loetmichel> soooo, display done... now i have to design a avr Mega8 board with RS232 for drivers and communication... (shi*, the night will be SHORT...) -> http://www.cyrom.org/palbum/main.php?g2_itemId=13314
[17:01:44] <sendoushi> archivist: break out board? what's the difference?
[17:02:25] <archivist> it has the opto isolators and easy wiring points to make the job easy
[17:02:57] <sendoushi> but theyre like... 50e more expensive so...
[17:03:15] <Jymmm> sendoushi: If I can make a suggestion from someone who has been there done that sorta thing... Before you even LOOK at your credit card or buy ANYTHING, plan out everything in advance. It's a lot of work, but will be well worth it in the long run. Including what exactly you plan on doing with it, etc. The biggest thing is gettign nickled and dimed to death on the little things.
[17:03:20] <sendoushi> that difference... maybe it's better for me to build with the less expensive one i dunno
[17:03:45] <sendoushi> Jymmm: that's why i'm asking and searching and researching :)
[17:03:56] <Jymmm> =)
[17:04:00] <sendoushi> to see which is excessive which isn't and decide what's best
[17:05:17] <sendoushi> but ... for a newbie is hard to find the information
[17:07:02] <archivist> some start cheap by scrounging free stuff from old machines etc
[17:07:32] <archivist> makes for a fugly machine though :)
[17:07:35] <sendoushi> there are not much of old machines around
[17:07:44] <sendoushi> i have some electronic components
[17:07:51] <sendoushi> from the construction of pedals and stuff
[17:08:25] <sendoushi> and ebay china has a lot of components :D
[17:08:32] <sendoushi> i just have to decide which way to go
[17:09:47] <sendoushi> fine fine would be to do a 4 axis one :D
[17:10:03] <sendoushi> but that is insane for the mechanics
[17:10:51] <syyl_> 4 axis programming without a cam is much more insane
[17:10:57] <syyl_> the mechanics are piece of cake :P
[17:11:07] <sendoushi> heeh
[17:11:48] <archivist> depends what you are making, gears are easy to write the gcode for
[17:11:54] <syyl_> yeah
[17:12:06] <syyl_> gears, spiral stuff is pretty easy
[17:12:14] <syyl_> but 4 axis simultan is hard :D
[17:12:18] <sendoushi> wait a sec... i need breakout board AND drivers?
[17:12:31] <archivist> yes basicly
[17:12:43] <sendoushi> so ... for this ... is like 200e :s
[17:12:44] <syyl_> leaving..
[17:12:48] <syyl_> good night
[17:13:05] <sendoushi> http://www.ebay.es/itm/CNC-Router-DIY-Kit-5-Axis-Breakout-Board-3x-M542-Stepper-Motor-Driver-1-0A-4-5A-/190685124812?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item2c65b818cc
[17:13:23] <sendoushi> plus motors... 300e for the electronics
[17:14:01] <sendoushi> or more...
[17:14:37] <archivist> I got my stuff spread over a long time so it didnt feel so bad
[17:15:37] <sendoushi> eheh
[17:15:43] <archivist> I started with 3 drivers one was rotary, Z remained manual for a time as I was gear cutting
[17:16:07] <sendoushi> have you ever done something with it that you sold?
[17:16:16] <archivist> my spindle is from a scrap lathe
[17:16:44] <archivist> sure I built it at work for making gears to sell
[17:17:17] <sendoushi> aah
[17:17:28] <sendoushi> that's kind of a problem... i don't know if i'll ever sell anything
[17:17:48] <sendoushi> or if i even want to sell anything
[17:18:30] <sendoushi> i'm a designer on a company and making another company. i want to do something with music also sooo... electronics and stuff are like the fifth wheel
[17:20:33] <sendoushi> http://www.ebay.es/itm/Universal-CNC-Frasmotor-Oberfrase-Spindel-motor-CauCau-850-W-/170857441551?pt=DE_Haus_Garten_Heimwerker_Elektrowerkzeuge&hash=item27c7e5a90f
[17:20:44] <sendoushi> what do you think about that?
[17:23:49] <archivist> looks right for your application
[17:24:07] <archivist> one for Jymmm http://www.youtube.com/watch?v=_VfSl0iGAus
[17:25:48] <Loetmichel> sendoushi: a wood router used as mill spindle should have "kress" oder "suhner" written on it
[17:26:10] <Loetmichel> you will not be happy with the cheap ones
[17:26:14] <ReadError> but in english :)
[17:26:24] <sendoushi> than... for now i'll go with dremel and then upgrade
[17:26:38] <sendoushi> http://www.ebay.es/itm/5-x-NEMA-17-42mm-hi-torque-stepper-motor-44Ncm-1-8degree-Reprap-CNC-robotics-/221042941117?pt=UK_BOI_Electrical_Components_Supplies_ET&var=&hash=item7917f6f0bc the motors
[17:26:48] <sendoushi> from what i heard... nema 17 are the more suitable
[17:26:50] <sendoushi> is that right?
[17:26:58] <sendoushi> can i find less expensive?
[17:27:27] <Loetmichel> sendoushi: are you a extreme cheapskate?
[17:27:35] <andypugh> sendoushi: It might be simplest to get a kit. This will get you started. http://www.ebay.co.uk/itm/200760055221
[17:27:39] <Loetmichel> ... looks this way
[17:27:46] <sendoushi> Loetmichel: cheapskate?
[17:27:55] <ReadError> sendoushi: grab a fireball v90
[17:28:04] <andypugh> NEMA17 are too small. You want at least size 23 for a router.
[17:28:13] <sendoushi> do i?
[17:28:14] <ReadError> http://www.probotix.com/FireBall_v90_cnc_router_kit/
[17:28:19] <Loetmichel> sendoushi: german: "geizkragen, Billigheimer"
[17:28:28] <sendoushi> ReadError: i'm from europe :s
[17:28:37] <sendoushi> i'm not german Loetmichel
[17:28:55] <andypugh> I suspect you are in Portugal?
[17:29:00] <Loetmichel> hmm, i thougt for the german ebay link
[17:29:21] <Loetmichel> how to describe cheapskate in englisch?
[17:29:49] <sendoushi> portugal yes
[17:30:30] <archivist> Loetmichel, like cheapskate :)
[17:30:43] <andypugh> Anyway, that €175 kit of PSU, driver and stepper will get you going.
[17:30:46] <Loetmichel> archivist: hrhr
[17:31:22] <andypugh> That's pretty much the same kit as I started with a few years ago. And I am still using two fo the steppers and the PSU.
[17:31:48] <sendoushi> andypugh: but still have to buy the breakouts right?
[17:31:52] <Loetmichel> sendoushi: IF you know what is possible with cheap parts AND have some electronics and mechanical engineering experience you can build a machien from scratch with scrap parts.
[17:32:03] <Loetmichel> BUT i wouldnt reccomend it as a first machine...
[17:32:21] <sendoushi> Loetmichel: yeah... i dont think that is th ebest approach as the first machine
[17:32:31] <Loetmichel> tha will look like my first afterwards and will operate as bad as it...
[17:32:40] <andypugh> sendoushi: No, parallel port plugs into that PCB, motors wire to the PCB, connect the PSU and watch the motors spin.
[17:32:55] <Loetmichel> sendoushi: WOUND NOT reccomend it
[17:33:02] <sendoushi> andypugh: so... this is like... "full" electronics right?
[17:33:49] <sendoushi> pretty interesting and maybe... the best approach for me since i need everything
[17:33:50] <Loetmichel> sendoushi: that wopuld result in something like that: http://www.cyrom.org/palbum/main.php?g2_itemId=2859
[17:34:14] <andypugh> Yes. Not the best quality, and the documentation will be difficult to understand. But they do work.
[17:34:28] <sendoushi> andypugh: maybe you can help me then :P
[17:35:02] <andypugh> Yes, we can all help you. Figuring out which pin does what on those boards is a bit of a game.
[17:35:21] <andypugh> But you say you can do electronics, so you can probably trace the tracks.
[17:35:40] <sendoushi> i didnt say that... i said i have a few knowledge about electronics
[17:35:44] <sendoushi> http://www.gbeshop.com/InfoBase/SAVEBASE/PKG/002083/Image/TB3_Wiring.png
[17:36:00] <sendoushi> yeah maybe this is the best approach
[17:36:19] <sendoushi> 80e cheaper and ... a kit which simplifies everything
[17:38:41] <andypugh> Those look like quite small steppers.
[17:39:04] <sendoushi> 23?
[17:39:22] <sendoushi> the image is from the link you gave me :D and that link has nema 23
[17:39:23] <Loetmichel> ah, the dreaded tb6560 boards
[17:39:40] <sendoushi> Loetmichel: anything to say about it? :P
[17:39:57] <Loetmichel> sendoushi: as a warning: these boards are not really fond of shorts and or spikes on the Powersupply.
[17:40:38] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12554 <- and switched polarity is VERY bad :)
[17:40:46] <sendoushi> talking chinese
[17:40:46] <sendoushi> :P
[17:41:01] <sendoushi> ah ok ok
[17:41:37] <Loetmichel> sendoushi: for electronic newbies: NEVER unpog a motor with active drivers
[17:41:46] <sendoushi> hum?
[17:41:48] <Loetmichel> NEVER short it somewhere
[17:41:50] <sendoushi> unplug?
[17:41:51] <andypugh> It is very pimportant never to disconnect the motors with the board powered up. I have similar chips with craters in..
[17:42:06] <sendoushi> so how would you say to power on and off?
[17:42:06] <Loetmichel> NEVER use a to small PSU with will result in pumping/spikeing voltage
[17:42:20] <archivist> carefully
[17:42:20] <andypugh> turn of the PSU, that's OK.
[17:42:21] <Loetmichel> all of that will kill the chips in an instant
[17:42:39] <sendoushi> Loetmichel: the kit has a psu
[17:42:41] <andypugh> But disconnecting motor wires with the PSU turned on is bad.
[17:42:50] <sendoushi> oh of course
[17:42:51] <sendoushi> ehehe
[17:42:58] <sendoushi> first goes the power
[17:43:00] <sendoushi> right?
[17:43:42] <WillenCMD> does anyone know if upgrading python will have any effect on linuxcnc?
[17:43:51] <Loetmichel> sendoushi: i have just repaired such a 3 channel bioard for a friend, there was a chip with crater in it because the PSU was a little too small and couldnt star under load.
[17:44:13] <Loetmichel> and the guy had it "pumping" for half an hour
[17:44:19] <Loetmichel> -> chips dead
[17:44:25] <Loetmichel> s/star/start
[17:44:29] <sendoushi> hm
[17:45:16] <andypugh> WillenCMD: It might have
[17:45:35] <sendoushi> i think i'll buy this kit :)
[17:45:43] <sendoushi> but first... i'll see the costs of the mechanics
[17:45:55] <Loetmichel> what we try to say: the cheap boards with TB6560 are ok, do what they are purchadsed for, but are a bit like a "mimosa"
[17:45:56] <andypugh> WillenCMD: Python 2.6.5 is cleary OK. What do you have?
[17:48:01] <WillenCMD> can anyone explain why _init_(self, halcomp): is giving me a type error
[17:48:07] <WillenCMD> TypeError: __init__() takes exactly 2 arguments (1 given)
[17:48:51] <WillenCMD> im pretty new to programming, this is driving me crazy because its clearly in other python programs i use for reference
[17:52:20] <micges> paste that line with this init
[17:53:01] <sendoushi> Loetmichel: like mimosa?
[17:54:15] <Loetmichel> a bit sensitive to enviroment
[17:54:22] <andypugh> I want a new set of crimping pliers for insulated terminals. I want proper anvils, not lots of playes next to each other. Can anyone recommend a particular maufacturer? Finding a pair on eBay.co.uk would be a bonus. The £200 Facom and the £120 Knipex are a little too spendy for me, though.
[17:54:53] <sendoushi> Loetmichel: oohh
[17:55:12] <andypugh> I _might_ just buy the £33 set from Maplin, because then I get to look at them.
[17:55:47] <Loetmichel> andypugh: cheap, good, fast(obtainable) ... pich any two ;)
[17:55:57] <Loetmichel> pick
[17:56:15] <WillenCMD> http://pastebin.com/cjv8seMw
[17:56:19] <WillenCMD> there is some of the code
[17:56:39] <WillenCMD> go easy on me when i say new to programming i mean like one month into it
[17:57:01] <Loetmichel> lat time i bought crimp pilers (for 1.5mm pitch EH-plugs) i payed 300 eurs just for the pilers...
[17:57:29] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11516
[17:57:33] <alex4nder> andypugh: I'm using a Pressmaster from sweden.
[17:57:37] <Loetmichel> this one.
[17:58:28] <alex4nder> andypugh: http://www.pressmaster.com/visa_produkt.asp?id=1032
[17:58:44] <micges> WillenCMD: ok now part of code where you call __init__
[18:05:14] <andypugh> alex4nder: I have looked at those, but I already have perfectly good tools for uninsulated crimps in 5 sizes.
[18:06:33] <andypugh> And €250 is more than I want to pay, too.
[18:06:49] <andypugh> If i was doing this as anything other than a hobby, mayb.
[18:08:07] <andypugh> The ideal tool would do red blue and mini-yellow (the size smaller than red) as I don't think I have ever used the biggest size, but don't have a proper tool for the little ones.
[18:08:35] <alex4nder> andypugh: I'm confused; I use a pressmaster with insulated crimps
[18:08:43] <alex4nder> the dies are replacable
[18:09:18] <andypugh> Yes, and if I dind't have good tools for other sorts of crimps, it would make sense to get the pressmaster set.
[18:09:31] <alex4nder> you can buy just one
[18:09:41] * alex4nder shrugs.
[18:10:43] <andypugh> I am also not perfectly convinced that they are 10x better than the mid-priced ones.
[18:11:45] <alex4nder> .. mine was $40
[18:11:52] <andypugh> Ah.
[18:12:12] <andypugh> http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=pressmaster&_sacat=See-All-Categories
[18:12:26] <andypugh> All the ones I can find are £200
[18:12:43] <andypugh> A set of jaws is $60
[18:12:47] <alex4nder> that's ridiculous.
[18:13:12] <alex4nder> I don't think I could afford to breath in england.
[18:13:14] <sendoushi> well guys arriverdeci!!!
[18:13:39] <Loetmichel> andypugh: make the claws for your existing pilers yourself?
[18:13:47] <Loetmichel> isnt THAT complicated
[18:13:58] <alex4nder> Loetmichel: it's almost as if this channel is full of machinists. ;)
[18:14:12] <Loetmichel> alex4nder: right ;-)
[18:14:18] <andypugh> Done right they are quite a complex shape. But the problem is that they don't actually meet tightly on my current pliers.
[18:15:27] <archivist> andypugh, 261042760968
[18:17:21] <archivist> or maybe 300721999474
[18:17:47] <andypugh> 261042760968 is for ferrules
[18:18:13] <archivist> but as a cheap bar steward I use something like 330744751721
[18:18:41] <andypugh> Eeew! Have you no pride?
[18:18:58] * archivist giggles
[18:21:25] <andypugh> <note to self, try to cook dinner before midnight on days when you have an 0830 meeting>
[18:21:44] <Tom_itx> what's the daughter card that goes with the 5I25?
[18:21:50] <Tom_itx> 7ixx? i forget the number

[18:22:13] <andypugh> 7i76, 7i77
[18:22:33] <Tom_itx> ok

[18:24:32] <Tom_itx> spare parts
[18:24:42] <Tom_itx> depth mics
[18:24:45] <Tom_itx> some of them
[18:24:57] <Tom_itx> with no anvil
[18:25:40] <andypugh> That was my thought at first, but then they looked like depth-stopped counterbores
[18:25:41] <Tom_itx> a couple look like they have a vernier scale which is good
[18:26:11] <Tom_itx> yeah i dunno
[18:28:33] <archivist> hmm interesting toys

[18:40:01] <JT-Shop> archivist: http://compound.modelengines.info/index.html
[18:49:48] <r00t4rd3d> so it isnt possible to move the graphic around in linuxcnc with my mouse?
[18:50:04] <r00t4rd3d> no clicking and dragging to the position i want?
[18:50:21] <WillenCMD> you know whats crazy, everyone who put in time to making linuxcnc and all its components made this very elaborate broad ranged 8 axis motion controller for just about anything. But there is no easy way to design a damn gui
[18:50:24] <ReadError> you can move the view
[18:50:25] <WillenCMD> lol
[18:50:28] <ReadError> you cant move the part
[18:50:32] <ReadError> thats done by homing
[18:51:26] <WillenCMD> its like a giant secret, not very well documented
[18:52:24] <archivist> JT-Shop, his photography is very good
[18:52:45] <WillenCMD> sorry, im just frustrated
[18:53:38] <archivist> you are one axis short there!
[18:54:29] <JT-Shop> yes, and lots of set up photos
[18:57:25] <archivist> I had a bad casting from the old stuart before the models part was sold to the current owners, was talking to new owners about how much the replacement would be but they sent it foc :)
[18:57:54] <archivist> so new is attempting to be as nice as the old
[19:01:34] <r00t4rd3d> whats the best way to go from sketchup to cutting?
[19:02:00] <jdhNC> I'm not sure sketchup belongs in that sentece.
[19:04:33] <r00t4rd3d> well what should i be using to create my own images/text?
[19:05:14] <jdhNC> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Cam
[19:05:27] <jdhNC> looks like there are some CAM plugins for sketchup though.
[19:07:11] <r00t4rd3d> http://www.cerebralmeltdown.com/cncstuff/index.htm
[19:07:43] <r00t4rd3d> Sketchup to CamBam Plugin
[19:07:54] <r00t4rd3d> http://www.cerebralmeltdown.com/cncstuff/page2/cambam_export/default.htm
[19:09:32] * ReadError didnt like sketchup
[19:09:37] <jdhNC> me either.
[19:09:43] <ReadError> ive had the best luck with solidworks+visualmill
[19:09:48] <jdhNC> it was more semi-art than accurate design.
[19:09:56] <ReadError> solidworks is super intuitive to use
[19:10:12] <jdhNC> assuming you can get past the pricetag or the theft.
[19:10:34] <ReadError> of course
[19:11:16] <r00t4rd3d> did you buy solidworks?
[19:11:42] <ReadError> I KNOW NOFFTTTINNGGGG!!!!
[19:12:06] <r00t4rd3d> windows only
[19:12:07] <r00t4rd3d> ?
[19:12:11] <jdhNC> http://www.becausewecan.org/Sketchup_to_CNC_via_OpenSource_Free_CAM_plugin
[19:12:12] <ReadError> yes
[19:12:21] <ReadError> you can run it in a VM though
[19:21:24] <andypugh> Alibre is OK, and reasnably priced.
[19:22:07] <andypugh> The main drawback is that it is Windows only.
[19:22:24] <ReadError> idk
[19:22:28] <andypugh> I think that freeCAD might get there, but it isn't there yet.
[19:22:31] <ReadError> solidworks i had my 1st part super fast
[19:22:40] <r00t4rd3d> ok say i find a image on the net and just want to use my paper and pencil setup to draw it, like this http://i.imgur.com/Hf95t.jpg how i easily get that into linuxcnc?

[19:23:17] <andypugh> If you don't mind rastering it.
[19:23:39] <r00t4rd3d> is pycam easier?
[19:23:47] <andypugh> In fact I _think_ you can probably just open the bitmap in Axis..
[19:24:05] <r00t4rd3d> im not even sure what axis is or if its installed
[19:24:20] <andypugh> It's the default user interface
[19:24:29] <r00t4rd3d> ok i got that then
[19:25:22] <ReadError> i did my 1st works in pycam ;)
[19:25:44] <r00t4rd3d> is it a pain to learn ?
[19:25:48] <ReadError> http://p.twimg.com/ArdaEghCQAEiIQ7.jpg:large
[19:25:49] <ReadError> nah
[19:27:20] <WillenCMD> what is the easiest way to send nml messages in python?
[19:27:38] <ReadError> http://p.twimg.com/Arnf0VnCAAA7iqs.jpg:large
[19:27:43] <ReadError> thats quality work man
[19:27:47] <ReadError> i got it at my desk at work ;)
[19:28:01] <r00t4rd3d> whats the official site of image2gcode?
[19:29:47] <ReadError> pycam is really simple bro
[19:29:50] <ReadError> you import the image
[19:29:53] <ReadError> select engrave
[19:29:55] <ReadError> bam
[19:30:10] <ReadError> can scale it
[19:35:02] <r00t4rd3d> im gonna go out and install it in a minute
[19:35:34] <Tom_itx> http://www.imagetogcode.com/
[19:37:37] <Tom_itx> somebody put it online: http://www.thuijzer.nl/image2gcode/
[19:39:01] <r00t4rd3d> i tried that but didnt end up with a good result
[19:39:27] <r00t4rd3d> probably cause i dont know what the #s should be
[19:49:53] <Tom_itx> r00t4rd3d, http://www.daycounter.com/Calculators/GCode/Feed-Rate-Calculator.phtml
[20:04:38] <WillenCMD> is there a way to use gladevcp without axis or touchy?
[20:41:27] <Thetawaves> anybody have any information about t62-3ax stepper drivers
[20:41:57] <Thetawaves> like pinouts? i found an image with all the parallel inputs, but none of the outputs
[20:46:10] <Jymmm> archivist: I may not care for cats, but I don't care for any animal to be hurt or terrorized in fear (couple of human exceptions do apply though)
[20:51:20] <Tom_itx> ok, use a pc type plug or thru grommet cord for the psu supply?
[20:53:33] <Jymmm> pc type plug? You mean an IEC connecotr?
[20:56:03] <Tom_itx> i guess
[21:03:44] <ReadError> ygg
[21:03:45] <ReadError> uhh
[21:03:49] <ReadError> where did cats come up?
[21:48:09] <r00t4rd3d> thanks for the help ReadError
[21:51:32] <ReadError> gotta zzzz here soon
[21:51:36] <ReadError> i wake up at 4:30 ;(
[21:51:46] <ReadError> i been where you at tho
[21:51:49] <ReadError> once you grasp it
[21:51:53] <ReadError> it becomes easier
[21:52:08] <r00t4rd3d> i need to stop messing with a pencil and just hook my router up
[21:55:02] <r00t4rd3d> trying to keep the right pressure on a pencil is a pain in the sack
[21:56:53] <jdhNC> stick it in a piece of cpvc pipe with a spring
[21:59:47] <r00t4rd3d> then it lifts off my piece but the spring holds it down
[22:00:06] <Tom_itx> or use a pen
[22:00:19] <jdhNC> or a router
[22:01:04] <r00t4rd3d> paint brush
[22:01:07] <r00t4rd3d> :)
[22:01:56] <ReadError> root
[22:02:02] <ReadError> if its touching
[22:02:05] <ReadError> and the lines get fine
[22:02:12] <ReadError> you have backlash
[22:02:21] <ReadError> you need to compensate for
[22:02:57] <Tom_itx> not so much backlash as a 'dull' cutter
[22:03:03] <Tom_itx> in this case a pencil
[22:03:26] <ReadError> im sayin in his z
[22:03:31] <ReadError> since its not returning to the same spot
[22:03:38] <ReadError> he used a marker before
[22:03:42] <Tom_itx> oh
[22:03:46] <Tom_itx> ok i didn't read that
[22:04:44] <r00t4rd3d> http://i.imgur.com/Pciee.jpg
[22:04:53] <r00t4rd3d> nah my "mount" just sucks ass
[22:06:18] <r00t4rd3d> the marker worked okay but that pic we were doing had too fine of lines
[22:06:32] <r00t4rd3d> and they where overlapping
[22:06:58] <r00t4rd3d> my marker tip was pretty beat up
[22:08:14] <r00t4rd3d> -/+ .001 is the difference between a good line or a shitty one with a pencil
[22:08:38] <r00t4rd3d> tape and zip ties is not too accurate
