[02:33:03] <ReadError> r00t4rd3d, construction question
[02:33:11] <ReadError> if im cutting a long piece of wood
[02:33:19] <ReadError> in one of those saws that you pull down
[02:33:28] <ReadError> whats the best way to keep it level to the cutting surface ?
[02:33:31] <r00t4rd3d> chop saw
[02:33:32] <ReadError> some blocks or something?
[02:33:35] <ReadError> yea chop saw
[02:33:42] <r00t4rd3d> clamp, another set of hands
[02:34:02] <r00t4rd3d> sawhorse
[02:34:22] <ReadError> well i got it on the ground
[02:34:35] <r00t4rd3d> stack up pieces of 2x4
[02:34:46] <ReadError> i tried, but they are like uneven
[02:34:49] <ReadError> too tall or too short
[02:34:55] <ReadError> so im using some really thin ply
[02:34:57] <r00t4rd3d> stand them straight up
[02:35:04] <ReadError> just figured there might be a better way
[02:35:10] <r00t4rd3d> a cut table
[02:35:33] <r00t4rd3d> that has 2x6 ripped the same height as your saw
[02:35:56] <r00t4rd3d> 7' out one side
[02:36:39] <jdh> mine is 3 1/2" tall, I use a 4x4 block or a pair of 2x4s
[02:38:13] <r00t4rd3d> most saw you turn a 2x4 on end and its almost perfect
[02:38:23] <jdh> they fall over
[02:38:29] <jdh> so I use 2 flat
[02:38:29] <r00t4rd3d> screws

[13:50:06] <r00t4rd3d> i just find it weird is he using a pre alpha build, who knows what os and kernel he is using, does he have rtai ? Does he have an actual machine hooked up or is he just simulating ?
[13:50:47] <jthornton> that has no effect on trying to do a G1 with a zero feed rate
[13:56:12] <r00t4rd3d> oh i just figured if he was on a newer version of linux without a rtai kernel and using pre alpha without a simulator build that would lead to issues.

[14:31:16] <Tom_itx> even though stupid it should be a valid code
[14:32:26] <Tom_itx> not saying anyone should ever use it, but it shouldn't error
[14:34:03] <archivist> his code lacked setting F before using G1, it should error if no(0) speed set imo, impossible is....impossible and an error
[14:35:43] <archivist> it is also better that you get an error than silence and a stationary machine from that line
[14:35:44] <Tom_itx> k, if it were set after then i agree

[17:04:52] <tjtr33> build up a surface from strips of alum on top of ply/mdf. 1 layer makes the wide slot for nut, 2nd layer make narrow slots for bolts. then you're tightening against metal.
[17:05:40] <tjtr33> or buy an extrusion tslotted table (Isel etc)
[17:06:08] <ReadError> well i figure if i use wood and tslot it, and its the spoil board
[17:06:14] <ReadError> i can toss it out when it gets ratty
[17:07:00] <tjtr33> why tslots, why not embed threaded inserts as you need, toss the board, save the inserts for another layout.
[17:07:04] <Tom_itx> i use a grid of tapped holes instead

[17:21:58] <Pitu> there is also error log when I run from app menue
[17:22:05] <tjtr33> Pitu open a terminal and run 'latency-test'
[17:22:25] <tjtr33> the terminal will give you more information about the problem

[17:24:47] <archivist> Pitu, most of us expect things will fail on a laptop due to power management
[17:24:51] <tjtr33> pcw_home, mesa plans on a fpga 'shield' for cubieboard?
[17:25:12] <pcw_home> Yes
[17:25:29] <Pitu> yes I read that but I wanted to give it a try
[17:26:00] <tjtr33> pcw_home, and an online school for fpga programming :)
[17:26:44] <pcw_home> We have pretty much all we need for FPGA motion in HM2

[17:29:40] <L84Supper> did you find a copy of the 400 or so page manual?
[17:29:43] <skunkworks> pcw_home: the local guy got the 5i25... He first tried stepconf wizard. :) I sent him the pncconf manual page and also the link to the forum with the xml and stuff.
[17:30:16] <skunkworks> If he can't get it - I think we are going to try to get together next weekend

[17:31:44] <pcw_home> Probably easiest to just use the hm2-stepper sample config and change the board name/config string
[17:32:13] <L84Supper> pcw_home: the kernel source unfortunately the only source of good info for it
[17:32:23] <Pitu_> i am not familiar with the terminal so hopefully I executed correctlz
[17:32:43] <pcw_home> I like the cubie as it includes the standard I/O on the main card but still brings out all the GPIO
[17:33:27] <tjtr33> Pitu, try same but boot from the LIVE cd ( what you got sounds like a 'permissions' or 'already there' problem )

[17:33:53] <Pitu> ok, I will do - thanks
[17:34:06] <archivist> Pitu_ which ubuntu are you using, did you install rtai etc (realtime kernel)
[17:34:22] <tjtr33> Pitu,if permissions, then you may not have a good install, if 'already there' its just becasue you've loaded it once already and tried again ( and again :)

[17:38:13] <L84Supper> pcw_home: there is a 500 or so page manual thats bit better than the 80 page floating around

[23:13:34] <spiderdijon> hi, I'm trying to adjust my axis acceleration and have got it some where I like it however it seems when the machine triggers a axis limit switch it still attempts to deccelerate instead of imeadiately stopping and it still crashes. This does not seem to happen with higher rates of acceleration. Is this behavior normal?
[23:16:03] <cradek> you would have to elaborate on the part of your findings where you report a difference between "higher" and not "higher" acceleration settings
[23:16:09] <cradek> I don't understand what you mean by "it still crashes"
[23:16:45] <cradek> but if you have your limit switches so near the end of travel that the machine cannot decelerate to a stop before running out of travel, you need to MOVE THEM inward. that is in no way a software problem.
[23:16:58] <ReadError> hey cradek, you are one of the linuxcnc devs right?
[23:18:43] <cradek> you can wire limit switches many ways, but in the most typical setup they will cause the servo amps to disable when they are hit. if you have some big mass moving, you can expect it to keep moving for a while in that unpowered state.
[23:19:16] <cradek> on a large or heavy machine, you may want to have mechanical OR electrical braking in that situation
[23:19:21] <spiderdijon> sorry yes that was a mistype, at higher MAX_ACCELERATION in the config ini file I find it stops before hitting the chassis, with lower values it crashes. I would have thought it would immeadiately stop generating step pulses when a limit switch was triggered instead of attempting to follow a acceleration (decceleration) profile.
[23:19:48] <cradek> what is your limit switch hooked to?
[23:20:10] <spiderdijon> parallel port, through some appropriate buffers
[23:20:19] <cradek> I mean in hal
[23:20:45] <spiderdijon> home and limit, is that what you mean?
[23:21:21] <cradek> perhaps you should pastebin your hal file
[23:21:29] <cradek> oops, brb
[23:21:31] <spiderdijon> ok just a sec
[23:21:32] <spiderdijon> thanks
[23:23:54] <spiderdijon> http://pastebin.com/TDAfK59f
[23:27:24] <tjtr33> and paste your .ini ( for soft limits and home method )

[23:28:47] <spiderdijon> http://pastebin.com/iqxbMCZq <-- ini
[23:30:14] <tjtr33> is err in all axis?
[23:30:34] -!- firephoto has quit [Quit: ZNC - http://znc.in]
[23:30:42] <spiderdijon> yes, all make a clunk noise at lower acc
[23:31:35] <spiderdijon> definitely feels like it is following a profile on triggering a limit switch
[23:32:01] <tjtr33> and the distance form the switch change to the soft limit is about how far ( not 1um i hope :)
[23:32:47] -!- firephoto_ [firephoto_!~phenom@] has joined #linuxcnc
[23:34:23] <tjtr33> the soft limit has to be encountered before the physical switch. the distance between must be enuf to allow deceleration at maximum rate. (plus a but more for safety )
[23:34:34] <tjtr33> bit
[23:35:06] <spiderdijon> the soft limits do indeed stop it before the hard switch is triggered once it is homed
[23:35:22] <spiderdijon> its while it is homing it crashes at lower acc
[23:35:49] <tjtr33> crash meaning 'hits end' ?
[23:35:55] <spiderdijon> sorry yes
[23:36:04] <spiderdijon> crashes into the chassis

[23:37:48] <tjtr33> was the limit switch also the home?... yes one switch for al
[23:38:04] <tjtr33> what is the distance from the switch change to the chassis?
[23:38:44] <spiderdijon> about 10mm from when in is triggered to the chassis
[23:40:13] <tjtr33> huge for me, ok, the homing method...
[23:40:29] <tjtr33> looking at your files for the homing type
[23:42:16] <tjtr33> got an index pulse or not?
[23:42:33] <spiderdijon> no, just dir and step
[23:43:47] <tjtr33> maybe you need USE_INDEX = No http://www.linuxcnc.org/docs/2.4/html/config_ini_homing.html see 0.1.2
[23:44:54] <tjtr33> mine is similar and i have HOME_USE_INDEX = NO ( and it works, bumps swx, backs off, creeps in, then rapids to my home posn, then next axis...
[23:45:22] <spiderdijon> hmm interesting, says default is no, do I have it set somewhere?
[23:47:21] <tjtr33> .ini in each [AXIS_whatever] stanza
[23:48:58] <spiderdijon> i'll put it in, thanks
[23:50:03] <tjtr33> mine pastebin.com/trw93kp7
[23:53:10] <tjtr33> lemme know if it works plz
[23:53:28] <spiderdijon> i'll try it now
[23:54:34] <tjtr33> the hi low accel thing is something else, this effort is just recognizing the matrix of params and not crashing.
[23:55:49] <spiderdijon> hmm seems to have had no noticable effect

[23:57:24] <tjtr33> move to ctr of travel, manually trgr the swx when re-homing, does it just keep moving towards end of travel?
