[18:53:06] <psha> anyone have a bit of time to take a look at m67 fixes?
[18:53:27] bootnecklad` is now known as bootnecklad
[18:53:38] <cradek> I fetched it and looked, but didn't test
[18:54:42] <cradek> it silently breaks if I set MAX_DIO or MAX_AIO greater than 64, right?
[18:55:37] <psha> yes
[18:56:37] <psha> possible workaround is to use byte array
[18:56:42] <psha> probably it would be better
[18:57:14] <psha> something like u8 mask[max(MAX_DIO, MAX_AIO)/8 + 1];
[18:58:05] <cradek> any reason not to set them both to 64?
[18:58:37] <cradek> I hesitate to have anything but the simplest possible bugfix for 2.5...
[18:58:40] <psha> maybe somebody need more then 64?
[18:58:56] <psha> ah, as for simple fix - yes, limit them to 64
[18:59:02] <psha> and add #error
[19:00:41] <cradek> I will push it after that
[19:01:09] -!- vladimirek has quit [Remote host closed the connection]
[19:01:24] <cradek> I mean, I am making those changes and then will pus hit
[19:01:47] <psha> also there is debug print left - i've removed it but not yet pushed new patches
[19:01:54] <cradek> I removed it already
[19:02:50] <psha> ah, thanks
[19:04:36] <cradek> thank you for the fix

[20:09:09] <skunkworks> cradek: I have not had a chance to check it in head.. but it seems if you abort a rigid tap operation - the next rigid tap cycle - the motion stops at the programed depth instead of waiting for the spindle to slow down. Then the next tapping cycle works correctly. I hope to try it in trunk tonight.
[20:09:33] -!- Kent_ has quit [Ping timeout: 260 seconds]
[20:15:45] <cradek> ouch, that sounds really bad
[20:16:24] <cradek> I wonder what abort during a RT should do

[20:35:00] <skunkworks> RT?
[20:35:07] <skunkworks> oh rigid tapping
[20:35:10] <skunkworks> duh
[20:35:18] -!- jbunch has quit [Ping timeout: 264 seconds]
[20:35:38] <skunkworks> I think a controlled stop (track the spindle down to 0) but that is just my opinion..
[20:36:10] <skunkworks> because if it is an emergency - the Estop should be pressed.. ;)
[20:36:24] <cradek> or reverse immediately and abort as soon as it's out?
[20:36:37] <cradek> or wait until the whole tap cycle is over then abort?
[20:36:46] -!- Kent_ has quit [Read error: Connection reset by peer]
[20:36:51] <cradek> fwiw I always wait until it's between taps and then abort :-)
[20:37:02] <cradek> but it should do something at least arguably sane
[20:37:06] <skunkworks> cradek: that is what I do now.. ;)
[20:37:19] <skunkworks> It didn't cause any issues as I saw it while tapping air.
[20:37:39] <cradek> if the tap breaks, I just let it finish - not like it's going to do any more damage
[20:37:48] <cradek> grindgrindgrindgrindgrindgrind
[20:37:56] <skunkworks> umm ;)
[20:38:06] <cradek> taps don't stay in the way very long
[20:39:11] <skunkworks> I still vote for a synced controlled stop... (if something started happening (tap slipping in holder) I don't know if I would want it to revearse..
[20:39:54] <cradek> but I bet there's no way to recover from a controlled stop without breaking the tap
[20:39:54] <skunkworks> then you say - 'use the correct holder!'
[20:39:55] <skunkworks> ;)
[20:40:18] <cradek> if you finish the cycle, the abort doesn't hurt anything
[20:40:48] <skunkworks> right
[20:40:55] <cradek> you'd never detect a slipping tap in time to do anything
[20:41:22] <skunkworks> heh - how do you think I new that it would not go all the way though the aluminum in 1 pass...
[20:41:26] <skunkworks> knew
[20:41:30] <cradek> ha
[20:41:32] <cradek> I could be wrong of course
[20:41:44] <cradek> you're loony for not putting the tap in a proper collet
[20:41:49] <skunkworks> I was tapping pretty slow though 200rpm
[20:42:02] <skunkworks> yes - I agree.
[20:42:12] <cradek> I'm surprised your drill chuck is centered well enough. most of mine kind of suck.
[20:42:35] <cradek> drills are forgiving I guess
[20:42:51] <cradek> brb
[20:42:56] <skunkworks> if you walk the key around the chuck a few times - it centers ok
