Subject: [Emc-users] Help with some sporadic followin errors
Hello to all,
We've almost finished to wire and configure the mazak to work with LCNC. So
far, joint movements and homing are working flawlessly. I'm using servos
in step+dir mode so no real feedback is coming from the joints of the
machine.
I happen to have some following erros on both X and Z axis from time to
time, mostly when the machine is not homed (but that could be my
impression). Anyway, I get the following error once the machine is home
too. I cut the servo thread period in half to 500000 ns and it seemed to
improve a little but I still get the errors from time to time.
I'm posting my HAL and INI files so you can take a look at them. I really
don't know what's causing this. By the way, so far I only got the error
when jogging the machine by hand, but never with g code.
Please let me know if there's something I can do to fix this behaviours.
I'll be uploading some videos in a few days.
Thanks as always!
Leonardo
I would delete the read/write GPIO functions, and set the stepgen maxaccel and
maxvel to 25% higher than the machine limits (they are likely set too close
currently)
