[02:23:22] <DJ9DJ> moin
[05:48:45] <jthornton> it is morning now
[06:44:17] <Loetmichel> mornin'
[06:53:21] <r00t4rd3d> when I cut old barn boards my machine shoots out splinters instead of sawdust.
[06:54:08] <r00t4rd3d> i had a chunk get caught under a bearings and I skidded out.
[06:55:33] <r00t4rd3d> 2nd time ive used my estop
[06:56:34] <r00t4rd3d> these people love these barn board name plaques Im making them and I think they look like ass.
[06:57:10] <r00t4rd3d> a mcdonalds ass*
[06:57:10] <andypugh> I quite like them.
[06:57:56] <andypugh> But I like old wood.
[06:58:31] <r00t4rd3d> lol, I did talk them into one oak plaque for their cottage: http://imgur.com/a/ugXIy
[07:00:22] <jthornton> did you design the ducks?
[07:00:45] <r00t4rd3d> loons and sorta
[07:01:34] <r00t4rd3d> oh wait, not these ones. I got these from cnczone.
[07:01:50] <r00t4rd3d> I had to fix them up some.
[07:01:59] <jthornton> I think I got a deer or something from there for my plasma
[07:02:16] <r00t4rd3d> http://www.cnczone.com/forums/misc.php?do=showattachments&t=19346
[07:02:26] <r00t4rd3d> ass load of dxf and other art files
[07:02:36] <r00t4rd3d> mostly dxf
[07:02:58] <jthornton> holy crap
[07:03:24] <r00t4rd3d> yeah thats what I said
[07:03:34] <r00t4rd3d> I think I used shit though.
[07:04:05] <r00t4rd3d> everyday it becomes larger also.
[07:06:24] <r00t4rd3d> http://www.cnczone.com/forums/general_metalwork_discussion/19346-share_your_files_part_art.html
[07:06:43] <r00t4rd3d> that is the thread
[07:06:59] <r00t4rd3d> the link i posted is all the attachments to that thread
[07:07:17] <jthornton> wow 500 pages
[07:08:02] <r00t4rd3d> thats why i just sort the attachments and ctrl-f what i am looking for lol
[07:10:19] <r00t4rd3d> there is lots of cool things in that thread but also a ton of garbage
[07:10:27] <r00t4rd3d> fyi
[07:11:20] <r00t4rd3d> here is another thread of dxf's
[07:11:22] <r00t4rd3d> http://www.cnczone.com/forums/woodworking_projects/5276-dinosaur_skeleton_other_models_dxf.html
[07:11:29] <jthornton> yea last time I got some dxf's from the zone about 20% were actually usable
[07:12:10] <r00t4rd3d> http://www.cnczone.com/forums/misc.php?do=showattachments&t=5276
[07:12:18] <r00t4rd3d> link to just the attachments to that one
[07:14:35] <r00t4rd3d> I think I am going to use the "download them all" firefox plugin and get everything to date.
[07:14:57] <r00t4rd3d> the use a DXF preview app to sort the garbage
[07:15:00] <r00t4rd3d> then*
[07:15:38] <jthornton> I've not see the download them all before
[07:16:17] <r00t4rd3d> https://addons.mozilla.org/en-US/firefox/addon/downthemall/
[07:16:21] <jthornton> download them all 2.0.15?
[07:16:35] <r00t4rd3d> yup
[07:16:44] <jthornton> thanks
[07:16:55] <r00t4rd3d> you gonna download them all?
[07:17:45] <jthornton> I installed the app LOL
[07:17:55] <r00t4rd3d> http://thepiratebay.se/search/vector/0/7/0
[07:18:04] <r00t4rd3d> tpb also has piles of vector art
[07:22:36] <r00t4rd3d> Im not gonna tell you to get Vector Magic while on that page either. Cause its unethical and wrong.
[07:25:22] <jthornton> lol
[07:26:15] <r00t4rd3d> drag and drop image to dxf
[07:36:25] <r00t4rd3d> I gotta make an urn.
[07:36:35] <r00t4rd3d> creepy.
[07:37:29] <r00t4rd3d> Some lady wants a box with her husbands name on it, thats it, so she can put his bag of ashes in it.
[07:39:35] <r00t4rd3d> CNC Coffins - Engraving for the Grave.
[07:40:20] <r00t4rd3d> "His work was so good it killed me!"
[07:47:23] <jthornton> lol, I'm spinning a bullet shape top for a 3" cannon shell for an urn
[07:51:10] <jthornton> lol, after hiding some columns in an open office spreadsheet, I see no way to show them again
[07:51:27] <jthornton> but I found a way
[07:52:07] <r00t4rd3d> it should be illegal for internet companies to monitor your personal usage.
[07:53:56] <r00t4rd3d> label it invasion of privacy, data caps no more!
[08:23:32] <andypugh> r00t4rd3d: I think you will find that the US is pushing for monitoring, and the EU is following. It's all to keep us safe from those nasty terrorists, obviously.
[09:04:24] <r00t4rd3d> the back button in browsers should retain its function after restart.
[09:35:50] <Tom_itx> that'll be a busy site this morning
[09:36:52] <r00t4rd3d> what site?
[09:36:56] <Tom_itx> andypugh obviously..
[09:37:05] <Tom_itx> cnczone
[09:37:17] <r00t4rd3d> why?
[09:37:43] <Tom_itx> i'll likely 'download them all' too
[09:37:57] <r00t4rd3d> oh lol
[09:41:36] <r00t4rd3d> jthornton, did you do it? How long did it take?
[09:42:15] <jthornton> no, never did I got tired of looking over the list and selecting the ones I though might be interesting
[09:42:55] <r00t4rd3d> thats what the download them all button is for
[10:00:14] <Tom_itx> how much hdd does it eat?
[10:10:28] <ReadError> 3d printers are hard ;(
[10:41:49] <andypugh> pcw_home: I have just found good reason to read "DoIt" as "Dolt" as I have been a dolt for weeks now, not reaslising that there is no "DoIt" command after I set the port back to normal after reading NVRAM.
[10:44:39] <L84Supper> ReadError, what type are you referring to?
[10:45:28] <L84Supper> FFF like reprap?
[11:01:34] <IchGuckLive> Hi all
[11:04:39] <JT-Shop> pcw_home: I'm still getting a communication error http://imagebin.org/232652
[11:07:19] <andypugh> JT-Shop: Does it start and stop OK?
[11:07:39] <andypugh> Anything in dmesg during the startup (before the fpga pinout listing)
[11:08:01] <pcw_home> JT-Shop: thats the field I/O so different channel now
[11:08:24] <pcw_home> At least I think it is different
[11:09:06] <andypugh> Ah, pcw_home, do you anticipate ever using ScaleMin and ScaleMax for data types 0x04 and 0x05?
[11:09:24] <andypugh> (ie, non-vol data)
[11:09:43] <pcw_home> Yes its possible
[11:10:32] <andypugh> I was thinking about using them for the max current and simialr with the 8i20.
[11:11:12] <andypugh> (so, if they are both non-zero the (read-only) parameter becomes a float not an int)
[11:12:51] <pcw_home> I think that makes sense (but is a little funny for things that are pure integers like baud rate selectors)
[11:13:41] <pcw_home> probably we will leave scalemin and scalemax 0 for these things
[11:13:55] <JT-Shop> field I/O power?
[11:14:14] <JT-Shop> I wonder if it is related to my limit switches somehow
[11:14:34] <pcw_home> Maybe, do you have both the 7I77 and 5I25 jumpered for external 5V?
[11:14:41] <JT-Shop> yes
[11:15:06] <JT-Shop> it happens randomly during homing
[11:16:24] <andypugh> pcw_home: OK, I will just leave it as it is.
[11:16:28] <pcw_home> Looks like something loose. We checked the 7I77 and the serial interface runs OK down to about 3V on the 5V power
[11:16:52] <andypugh> The only problem is that halshow always displays unsigned ints in hex.
[11:17:05] <pcw_home> How is the 7I77 cabled to the PC?
[11:17:27] <andypugh> So my 8i20 max current is 0x000002EE
[11:17:54] <JT-Shop> Ok, I'll reseat the cables and try some more
[11:18:00] <pcw_home> Well you get god at reading Hex
[11:18:19] <andypugh> Yes, I am well awate that 2EE is 750 now :-)
[11:18:29] <pcw_home> Do you have a direct connection from th IEEE cable to the 7I77?
[11:18:51] <JT-Shop> yes
[11:19:13] <pcw_home> no extentions, flat cable etc?
[11:19:32] <JT-Shop> is was not sitting exactly correct on the 7i77
[11:21:07] <JT-Shop> I guess it would help to screw some mounting things into the 7i77 plug so the IEEE cable has something to fasten to
[11:22:11] <andypugh> JT-Shop: You could take the ones off the 5u25 :-)
[11:22:17] <pcw_home> doesn't cable have thumbscrews
[11:22:22] <pcw_home> ?
[11:22:40] <andypugh> (I just looked and the 5i25 has bail nuts, and the 7i76 doesn't)
[11:22:55] <JT-Shop> yes, but there is nothing on the connector for them to screw to
[11:23:07] <pcw_home> what?
[11:23:17] <andypugh> They both have threaded holes, but the thumbscrews don't reach
[11:24:00] <JT-Shop> like if you mounted it to a panel you screw the stand off looking things into the connector but they are not there
[11:24:19] <andypugh> On the 5i25 there are the little standoff-like mounting screws (for PCI plate mounting)
[11:24:20] <pcw_home> Oh missing jackposts
[11:24:37] <JT-Shop> yea, them things
[11:24:49] <Tom_itx> gee i bet a guy with a lathe could make a few
[11:24:59] <andypugh> I have a box full.
[11:25:02] <pcw_home> I'll make a note to production to install these
[11:25:04] <Tom_itx> me too
[11:25:06] <JT-Shop> been there done that :)
[11:25:29] * JT-Shop goes to take a couple off of an unwanted pc card
[11:25:50] <andypugh> So, that's JT sorted. Now my turn.
[11:25:53] <pcw_home> (quashing lame joke about jillposts)
[11:26:57] <andypugh> My RevD 8i20 shows a busundervolt error at 58.8V. The nvbusundervmax is 450 and nvbusundervmin is 350.
[11:27:02] <andypugh> Seems odd.
[11:28:13] <pcw_home> Does seem odd, is the voltage readout about right?
[11:28:51] <pcw_home> (comes from the same source)
[11:28:59] <andypugh> My multimeter says 59.2
[11:29:19] <pcw_home> ripple?
[11:29:27] <andypugh> 58.8 is the 8i20's opinion of the voltage
[11:29:59] <pcw_home> OK so thats good
[11:30:37] <pcw_home> It may in fact be a bug
[11:31:00] <pcw_home> I will check on Monday
[11:31:08] <andypugh> I am also a bit puzled that unplugging the enable connector doesn't set the no-enable fault pin
[11:32:48] <pcw_home> Thats sounds really broken
[11:32:50] <pcw_home> can you start without an external enable?
[11:33:41] <andypugh> With this board I can't start at all (no motor power, the green LED is happy)
[11:34:27] <pcw_home> red fault LED on?
[11:34:35] <andypugh> No
[11:35:09] <pcw_home> is the fault LED on with no external enable?
[11:35:17] <andypugh> No.
[11:35:31] <andypugh> Should it be?
[11:35:58] <andypugh> Let me switch to the other board and see what I get. (RevB, original firmware)
[11:37:04] <pcw_home> Yes. Its probably a bug introduced by the wait-for-vbus OK to start motor PWM patch
[11:37:06] <pcw_home> why 58V is not enough, I dont know though
[11:37:57] <pcw_home> it probably does not even look at the enable until VBUS is OK
[11:37:59] <pcw_home> We will fix this (if it has not already been fixed)
[11:43:13] <JT-Shop> got this again when running a test program http://imagebin.org/232652
[11:45:32] <andypugh> The older board behaves more as expected, though isn't setting the enable fault pin. However this might be related to mapping between my driver and the statis bits.
[11:50:40] <pcw_home> JT-Shop if its not a power or connection problem, it might be a ground loop so
[11:50:42] <pcw_home> sizeable HF ground current flowing between 7I77 and PC. You might try
[11:50:43] <pcw_home> grounding the 7I77s GND (5V gnd pin or spare encoder gnd pins) to frame ground
[11:52:35] <andypugh> I think I might be embarassed.
[11:52:53] <andypugh> One of the wires in my enable plug was the wrong side of the clamp.
[11:53:38] <pcw_home> Thats always a hazard with rising clamp connectors
[11:53:55] <andypugh> Unplugging the "enable" plug sets my "bus undervolt" flag..
[11:54:20] <pcw_home> Well that explains a few things
[11:54:32] <andypugh> I think I need the correct status bit mapping info.
[11:55:49] <andypugh> Which is the current manual version?
[11:56:15] <pcw_home> The 8I20 manual is fairly ancient and needs updating
[11:56:54] <pcw_home> but AFAIK the status bits have never changed
[11:57:50] <pcw_home> well REVD may have moved BUSLOWV from a fault to a status bit
[11:59:13] <pcw_home> Also JT-Shop make sure you dont have any encoder cable shields terminated at the 7I77 (sure fire way to get motor PWM noise coupled into the 7I77s gnd)
[12:01:19] <andypugh> I have a feeling that I have fault and status switched, looking at it.
[12:11:11] <JT-Shop> pcw_home: shields are only grounded to the frame on one end only
[12:11:47] <JT-Shop> I do see a small voltage when I measure between the 0vdc pin and ground on the 5vdc power supply
[12:19:44] <pcw_home> bad connection maybe?
[12:19:46] <pcw_home> You can get an idea what the 7I77 sees 5V wise by
[12:19:47] <pcw_home> measuring at the SSERIAL expansion port (far pins =1 and 8)
[12:19:52] <pcw_home> 1 and 8
[12:26:05] <JT-Shop> grounding the 0v didn't help
[12:35:09] <pcw_home> is this random when you do moves
[12:35:17] <JT-Shop> yes
[12:35:33] <pcw_home> Does sound like a ground loop
[12:37:49] <r00t4rd3d> http://i.imgur.com/XXcSG.jpg
[12:38:15] <r00t4rd3d> this family REALLY liked the moose.
[12:38:38] <pcw_home> sources could be encoder or analog
[12:38:40] <pcw_home> do the drives have a IN+ and IN-? or is the drive GND connected to 7I77 GND?
[12:39:52] <JT-Shop> SSERIAL sees 4.99vdc
[12:40:06] <JT-Shop> checking
[12:41:24] <JT-Shop> the drive ground is conected to IN- along with the -
[12:41:53] <JT-Shop> no that is wrong
[12:42:13] <JT-Shop> the velocity cable shield is connedted to the 7i77 IN- only
[12:43:12] <pcw_home> shield is open at the drive end?
[12:44:16] <JT-Shop> yes
[12:45:28] <pcw_home> and drive has in+ and in- (not in+ and gnd)
[12:47:20] <pcw_home> you may have to Ohm it out
[12:47:22] <pcw_home> (disconnect 7I77 cable and 5V power)
[12:47:24] <pcw_home> and make sure you dont have a low impedance
[12:47:26] <pcw_home> connection from 7I77 GND to frame GND
[12:47:50] <pcw_home> (less than 100 or so Ohms anyway)
[12:48:18] <JT-Shop> the drive has no labels on the velocity input connectors :(
[12:49:18] <JT-Shop> disconnect the IEEEE cable and the 5v power?
[12:49:38] <pcw_home> Yes
[12:49:48] <pcw_home> do this powered down
[12:50:04] <JT-Shop> ok
[12:52:01] <JT-Shop> from the IN- to ground is 6 ohms
[12:53:20] <pcw_home> thats pretty low, what is -IN at drive to drive frame GND?
[12:56:00] <JT-Shop> I think that is what I measured, one lead to frame ground and with the connector on the 7i77 still connected the other lead to IN-
[12:58:31] <pcw_home> This is a good opportunity to check any other paths to ground (if you unplug the encoder connectors does the resistance stay the same?)
[13:22:30] <JT-Shop> no change on the encoders, when I unplug one drive the ohms is 14 when I unplug 2 it is 350
[13:24:45] <pcw_home> that may be the noise path (If thats what the problem is)
[13:25:29] <pcw_home> a 100 Ohm resistor in the in- lead might fix it (if its a ground loop problem)
[13:25:39] <JT-Shop> ok
[13:26:18] <JT-Shop> the Z drive is about 300 ohms the X and Y are low
[13:26:49] <pcw_home> if it does fix it than a common mode choke might be a better solution
[13:26:57] <pcw_home> then
[13:28:52] <pcw_home> Errors only when moving sure sound like PWM noise current from drives flowing through
[13:28:54] <pcw_home> IEEE cable
[13:32:53] <pcw_home> bbl
[13:33:09] <JT-Shop> me too
[13:42:01] <alex_joni> evening
[13:45:02] <andypugh> is pcw_home there?
[13:56:22] <pcw_home> back
[14:05:02] <alex_joni> new toy: http://www.chip.de/ii/1/5/4/8/8/8/2/7/ASUS_Zenbook___UX31A_12-9c3c1c2dced1d38a.jpg
[14:05:03] <andypugh> How many bits in the status register?
[14:06:37] <kirk_wallace> JT: I'm trying out your tutorial with gui1.glade and gui1.py. I started an AXIS sim sample, then ran gui1.py, but I get an error hat ends with "AttributeError: 'NoneType' object has no attribute 'show'". Does anything come to mind that I should check?
[14:07:20] <owhite> hello people. I'm running axis, and pycvp. I was wondering if people had a suggestion for how I could make a call to an executable from either axis or pyvcp?
[14:11:15] <skunkworks> M1xx and a bash script...
[14:11:37] * skunkworks tries to sound like he knows what he is talking about
[14:12:48] <pcw_home> andypugh: there are 16 bits in the specific 8I20 status in interface reg 1
[14:12:50] <pcw_home> (which is only valid if comms are running)
[14:13:38] <andypugh> skunkworks: And an MDI-commnd
[14:14:12] <andypugh> Ah, we both failed to notice him disappear again
[14:14:13] <skunkworks> right
[14:14:17] <skunkworks> heh
[14:14:31] <andypugh> pcw_home: I am getting rather confused.
[14:15:31] <pcw_home> Probably our manual, designed to stun and confuse...
[14:15:47] <andypugh> Looking at the individual bits with the bus voltage off only bit 3 (of the 0 to 31 bits) is high. If I unplug the enable then bit-8 gets set.
[14:16:41] <pcw_home> bits in interface reg 1?
[14:16:48] <andypugh> If I turn the power on then bit 3 goes off, and bit 9 goes high.
[14:16:51] <andypugh> Yes
[14:17:05] <kirk_wallace> owhite: This link comes to mind: http://linuxcnc.org/docs/html/hal/halmodule.html
[14:18:30] <andypugh> If I unplug the enable plug then bit 9 goes low, and bit 8 goes high.
[14:20:17] <andypugh> Which, if it indicates anything, indicates that Faults are in the LSW, not the MSW? as bits 8 and 9 don't feature in the status register.
[14:21:23] <andypugh> But I would expect the hardware enable to toggle bit 1 or 17
[14:21:23] <pcw_home> Yeah it looks like MSW/LSW are reversed in the manual
[14:29:54] <pcw_home> Ahh its a version change
[14:29:56] <pcw_home> buslowV and no enable moved from faults to status in rev D
[14:30:39] <pcw_home> noenablestatus_bit equ 0100h
[14:30:41] <pcw_home> pidonstatus_bit equ 0200h
[14:30:53] <pcw_home> buslovstatus_bit equ 08h
[14:31:45] <andypugh> I just went back to the old RevD and it does make more sense. (bit 24 when I turned the DC off)
[14:32:34] <pcw_home> (so the interface will start without these present but PWM.PID will wait until they are OK)
[14:32:40] <andypugh> And bit 17 for no-enable.
[14:33:08] <andypugh> So… How do we handle this?
[14:33:44] <andypugh> Different pinouts depending on software revision sounds bad.
[14:34:51] <pcw_home> you can or them together (the no enable and buslowv status were always 0 on revB)
[14:35:53] <andypugh> I don't think I can with the new structure. I _can_ create duplicate pins.
[14:36:05] <pcw_home> the no-enable and buslowv faults are always 0 on rev D
[14:36:45] <pcw_home> just or the bits together before any other processing
[14:36:46] <andypugh> Is it a firmware version thing or a revision thing?
[14:37:00] <pcw_home> its a firmware thing
[14:37:31] <andypugh> I don't have a way to do any logic on the pins, it's all a pseudo-PTOC now.
[14:38:50] <pcw_home> We really didnt have a choice since we changed BUSLOWV and ENABLE-IN to be status flags instead of faults
[14:39:46] <pcw_home> (to allow link startup without busv or perhaps interlocks open)
[14:40:54] <pcw_home> (current loop PID/PWM still wont start without these)
[14:41:05] <andypugh> I think it will be fine. we can just have fault.buslow and status.buslow pins. Only one will ever work on any particular board, but that seems fine
[14:42:05] <pcw_home> Yeah and eventually we will be able to update the firmware more easily
[14:42:06] <pcw_home> (no UART config needed anymore at least)
[14:45:31] <andypugh> This restructuring is all part of my idea of a way to change the firmware, and is all because I want to change my firmware :-)
[14:47:58] <pcw_home> You can do it VIA SSLBP with SSLBP V35 or > but its somewhat involved
[14:48:00] <pcw_home> (set remote device jumper to setup mode send lots or mystery commands to remote --> done)
[14:49:33] <pcw_home> I will update the 8I20 manual to reflect the REVD changes
[14:50:12] <andypugh> Is it rescuable if it goes wrong?
[14:50:39] <pcw_home> Yes as long as it does not write to the wrong place
[14:51:12] <pcw_home> then only rescue-able with a PIC programmer
[14:52:58] <pcw_home> basically there are 2 sets of code, the setup code and the run mode code
[14:53:00] <pcw_home> the processor always starts in the setup mode code than jumps to the run
[14:53:01] <pcw_home> mode code if the jumper is set for run
[14:53:32] <pcw_home> setup mode code is only rarely updated
[14:55:34] <andypugh> I will no doubt be asking for more details when the time comes.
[14:55:35] <pcw_home> so a firmware update utility need only write to the run mode area
[14:56:25] <jdh> there is a phone number and email address at teh bottom... He would happily discuss/explain anything needed.
[14:56:30] <jdh> <urk>
[14:59:39] <pcw_home> The problem now is that firmware update is not terribly complicated but our examples are because they are universal (hardware COM Serial port, hardware mesa serial port, OS serial port, SSLBP, PCI/mem/ EPP/ IO interface etc etc)
[15:02:32] <andypugh> I would only anticipate attempting to do it via SSLBP
[15:03:23] <pcw_home> Thats the only way that makes sense for LinuxCNC
[15:03:39] <andypugh> I would be looking at a command line sequence of loadrt hostmot / loadrt hm2_pci / loadrt sserial_flash firmware=path/to/firmware
[15:04:24] <andypugh> or loadrt sserial_flash 8i20.0.0.nvmaxcurrent = 30
[15:04:56] <andypugh> It's going to be a starnge sort of HAL component that always exits.
[15:07:20] <pcw_home> What about adding it to Michael Gs Mesaflash?
[15:08:45] <pcw_home> The latest does 7I80s as well as PCI cards (but not EPP however)
[15:11:09] <pcw_home> or rather than adding/ just use its code base as a way to get low level card access
[15:13:07] <pcw_home> We really need to have a firmware wrapper with the card name so you can't write 7I66 firmware to a 8I20 for example (or maybe just use the file name if you trust people not to change it)
[15:14:04] <pcw_home> bbl feed store run

[17:06:02] <r00t4rd3d> Grrr, I spend all yesterday, last night and this morning finishing 4 signs for these people, they just emailed me, "Oh we will be in Friday night to pick them up"
[17:06:43] <r00t4rd3d> how do you politely say: FUCK NO, come pay me now.
[17:08:45] <andypugh> I think it would be very hard to say that politley.
[17:44:12] <r00t4rd3d> http://en.wikipedia.org/wiki/Percussive_maintenance
[17:56:12] <L84Supper> http://www.automationtechnologiesinc.com/products-page/cnc-controller-box/980mda-milling-drilling-controller-for-stepper-motor-system would someone really choose this over a LinuxCNC PC + Mesa controller?
[17:56:50] <L84Supper> or this? http://www.automationtechnologiesinc.com/products-page/cnc-controller-box/980mda-milling-drilling-controller
[18:00:21] <andypugh> They might, that's very cheap for a CNC controller.
[18:00:35] <andypugh> Just not as cheap as _we_ know it can be.
[18:01:57] <L84Supper> andypugh, have you ever seen a controller like those with pre-flight simulation or trajectory planning?
[18:02:11] <andypugh> No
[18:09:36] <r00t4rd3d> do you feed those things gcode?
[18:11:22] <andypugh> pcw_home: My current version of the driver starts, srops. and restarts a RevD board perfectly.
[18:12:05] <andypugh> However it won't re-start a RevB board without me disconnecting the RJ45. Is this my fault or yours?
[18:30:18] <L84Supper> r00t4rd3d, yes, feed them g-code or program them from the keypad

[18:47:38] <tjb1> Stupid MLB playoffs...
[18:48:21] <r00t4rd3d> ahh more fagbook pics huh
[18:50:30] <tjb1> yeah get used to it
[18:50:43] <tjb1> I moved them all to a nice album just for you
[18:50:48] <r00t4rd3d> im surprised it allows you to direct link to images without signing in or liking something
[18:50:58] <tjb1> I made it visible to the public
[19:03:01] <tjb1> Has anyone ever had a good experience at Fastenal?
[19:03:22] <r00t4rd3d> they have some sweet nuts.
[19:04:06] <r00t4rd3d> Ive never had a bad experience with them
[19:04:10] <pcw_home> andypugh Will 2.51 work?
[19:04:27] <andypugh> No, I did that test and 2.5.1 is just as bad.
[19:04:52] <andypugh> So I feel I can push my current patch then try to fix the problem in 2.5.1
[19:04:53] <tjb1> They wouldnt break a pack open for me
[19:05:48] <andypugh> I have a box of 1000 M4 nuts for a similar reason. I think it cost me £10 and I only needed 6
[19:07:00] <tjb1> I have no problem buying a full pack but when they are charging 2x of what McMaster wants...
[19:07:25] <r00t4rd3d> you cant compare local shopping with internet shopping.
[19:07:33] <tjb1> Yes you can
[19:07:43] <andypugh> He just did :-)
[19:07:47] <tjb1> Fastenal wants to be a supplier
[19:09:05] <r00t4rd3d> if you dont understand why you can get stuff cheaper online then locally you need to lay off the plasma gas.
[19:09:22] <tjb1> Do you realize how many bolts I can get shipped to my house for $5?
[19:09:44] <L84Supper> way more than 10 I bet!
[19:10:22] <L84Supper> you mean including the cost of shipping?
[19:10:34] <tjb1> No, all my orders so
[19:10:44] <tjb1> All my orders so far havent been above $5 shipping
[19:10:56] <tjb1> Well…$5.60 or something
[19:18:31] <Tom_itx> go to ACE hardware if you want onezies and twozies. fastenal sells bulk
[19:20:25] <Jymmm> Yeah, ACE had all kinds of funky hardware in EACH qty
[19:20:54] <Tom_itx> it's ALL overpriced anymore but they usually have it
[19:22:53] <r00t4rd3d> http://www.youtube.com/watch?feature=player_embedded&v=_ls7KUbQy3k
[19:22:58] <r00t4rd3d> he sells those for 2k
[19:23:06] <r00t4rd3d> http://www.woodthatworks.com/
[19:26:00] <tjb1> Wonder how many times he cut those so they didnt hit
[19:26:21] <Tom_itx> measure twice, cut once
[19:31:52] <tjb1> http://lolchamp.com/elephant-father-son-bonding
[19:34:35] <r00t4rd3d> How come the dimensions shown in the preview window of LinuxCNC never match what I set the material dimensions too in my cam program?
[19:36:57] <jdh> they should be off by the radius on each side
[19:37:16] <r00t4rd3d> its always less
[19:37:32] <Tom_itx> cutter center?
[19:37:34] <r00t4rd3d> i set 5x5 it shows as 4.09 or some shit in lxcnc
[19:37:55] <jdh> that is teh material size, or the max cut size?
[19:37:55] <Tom_itx> the preview is for a tool path
[19:38:04] <Tom_itx> a tool path will be the cutter center
[19:38:21] <Tom_itx> add or subtract the tool radius and see if that makes a difference
[19:38:52] <jdh> linuxcnc doesn't know or care what size your material is.
[19:39:00] <Tom_itx> i care
[19:39:04] <r00t4rd3d> me too
[19:39:09] <Tom_itx> but not about yours
[19:39:12] <r00t4rd3d> its a pain to center stuff
[19:39:20] <Tom_itx> no it isn't
[19:39:40] <Tom_itx> you do it in your cad program and set your G54 offset to x y z zero from that
[19:40:50] <Tom_itx> sometimes we would use a tooling ball as the coordinate zero
[19:41:15] <Tom_itx> so long as you have a common reference point
[19:54:00] <tjb1> r00t4rd3d has got too many common reference points for a good reference point.
[19:54:36] <Tom_itx> did he shuffle his cards once too many times?
[20:24:52] <tjb1> He huffed too much poly making all these paradise boxes
[20:32:49] <skunkworks> one of these makes centering easy. http://www.youtube.com/watch?v=U61ub6mtpH4&feature=share&list=UUHk52YjGT8HryRYmJKSl-lg
[20:33:30] <skunkworks> I had to mill/drill some blocks.. I just stuck them in the vise and made a probing routine that checked all 4 sides.
[20:39:23] <Valen> camera for centering ftw
[20:39:46] <tjb1> eyeball for centering ftw
[20:40:15] <Valen> we got the best tram ever on our mill with that
[20:40:23] <Valen> eyeball and rubber mallet
[20:43:59] <r00t4rd3d> skunk is that your video?

[20:57:49] <skunkworks> r00t4rd3d:
[20:57:51] <skunkworks> yes
[21:04:00] <tjb1> Putting an L0 on the G83 line makes it not drill at whatever position the G83 was started correct?
[22:04:00] <Tom_itx> skunkworks is that your spindle temperature compensation video as well?
[22:04:15] <Tom_itx> how do you determine how much it will grow?

[22:38:33] <r00t4rd3d> now i got so much I cant make up my mind
[22:38:48] <r00t4rd3d> Valen, dxf models
[22:38:55] <r00t4rd3d> or art whatever you call them
[22:38:55] <Valen> of?
[22:39:04] <r00t4rd3d> everything you can imagine
[22:39:11] <r00t4rd3d> and then some
[22:39:22] <tjb1> some of em are pretty poor though :P
[22:39:28] <r00t4rd3d> sure, lots
[22:39:33] <tjb1> someone just rast2vectored it and threw it up
[22:39:37] <r00t4rd3d> some are badass
[22:39:51] <tjb1> gonna take me ages to sort that
[22:40:05] <r00t4rd3d> get a dxf previewer
[22:43:18] <tjb1> I wish I could just use the space preview
[22:43:22] <tjb1> I have to open them in draftsight
[22:43:46] <r00t4rd3d> http://www.longbowsoftware.com/Previewer.php
[22:43:56] <r00t4rd3d> preview them in explorer

[22:46:25] <r00t4rd3d> but look at 1_003.dxf
[22:47:00] <r00t4rd3d> i can just double click on them and Aspire opens them right up quickly
[22:47:15] <tjb1> draftsight opens them instantly
[22:47:21] <tjb1> what is 1_003, I already renamed it and forgot
[22:47:33] <L33TG33KG34R> someone here do aluminum extrusion in canada?
[22:47:34] <tjb1> or deleted it

[23:35:37] <ursa> anyone home? I'm getting a peculiar result when trying outputs on parallel port
[23:39:30] <ursa> mhaberler: do you have an experience with parallel port outputs? I'm getting a peculiar result.
[23:40:09] <mhaberler> what do you mean by 'peculiar result'?
[23:42:18] <ursa> I'm trying to get a spindle on signal, but when I change the pin assignment in stepconf for pin 1, I get nothing.
[23:42:53] <ursa> However, pin 17, which is marked amplifier enable does give me the spindle on/off signals. If I change the assignment to spindle on, I get nothing.
[23:43:30] <mhaberler> I am sorry - I have never used stepconfg
[23:43:57] <ursa> unfortunate. I suppose I'll survive anyway <grin>
[23:44:29] <ursa> maybe someone else knows about the inner peculiarities of stepconf and the rest.
