If so: I had that problem with the Toshiba VFS-11. See the note in my dr

It seems I'm missing something obvious. I thought the idea was to move
the motor back & forth while comparing the commanded (presumably, the
actual) position with the encoder's (also, presumably, the a

All this talk of lowering the servo thread had me thinking back to when
I was setting up the K&T. I wanted to try to lower the servo thread for
testing. I could not go much slower the the 1ms default or I would get
real time delays. After some consultation on irc - it was decided that

Yes, I found that too. I built my code based on the GS2 module and

Greetings;
Since I made the top side of a board look pretty good, but got stymied by
linuxcnc's refusal to do a move to tool change from .1 to Z6.0 when it had
8.5" of room, I figured I would play with pcb-gcode & see if I could do the
