#linuxcnc-devel Calendar

03:34 PM andypugh_: I spent a couple of evenings getting an LCD / 7i73 combination working to debug this LCD problem in Master.
03:36 PM andypugh_: And, annoyingly, I am not seeing any problem.
03:36 PM andypugh_: Has somebody already fixed it while I was away?
03:44 PM pcw_mesa: Not sure what the history is
03:54 PM andypugh_: pcw_mesa: Have you reproduced the problem?
04:09 PM pcw_mesa: no I would have to dig out my display which has gone missing after our move
04:09 PM pcw_mesa: I think Mike Eitel ( sp? ) and Norbert ( gmoccapy guy ) both had the same issue after moving to master
04:15 PM andypugh_: I am pretty puzzled, as I don’t think anything should be different in normal process data mode.
04:17 PM andypugh_: (And I am certain that the driver does _not_ set all the params to zero, I don’t know where that idea came from.
05:07 PM mozmck: makefiles confuse me
05:09 PM pcw_mesa: andypugh_: rene-dev in irc suggested that it mighty set parameters to 0
05:09 PM pcw_mesa: might
05:09 PM andypugh_: Yes, I will have to beat him later.
07:19 PM skunkworks: I have notice an odd problem.. The setup I have now - (2 different computers and hardware) the first jog move is a heck of a clunk. restarting linuxcnc causes the same behavior..
07:19 PM skunkworks: 2.7
07:20 PM skunkworks: I will dig into this weekend. I had myself convinced it was the drives - but they only take step/dir so unknowing of the restart of linuxcnc
07:20 PM skunkworks: after the first cluck - jogging is normal and smooth
07:21 PM skunkworks: (before homing)
07:22 PM skunkworks: drives stay powered (in this test) through a linuxcnc restart
07:24 PM skunkworks: all axis
07:25 PM skunkworks: (i dont know if all axis clunk or only the first jog press)
09:56 PM seb_kuzminsky: that's a strange clunk
09:56 PM seb_kuzminsky: maybe the drives go into power-saving mode, then power the motors up to full current when the first step comes in, and that causes the steppers to realign?
09:56 PM * seb_kuzminsky <-- clueless
