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)
Sounds like good advice, but which ini var is considered the machine
speed limits?
Thanks Peter.
The per axis and per joint maxvels
