Hi guys!
I hope you're all doing well,
I've had a really strange behavior with my router on the Y axis when
homing. Basically one joint tried to move while the other didn't. I could
ESTOP the machine before anything happened but this only happens from time
to time when homing. The drivers show no error signal and everything looks
normal even after the behaviour. I'm monitoring everything before I hit
home axes so I really can't track where the problem is.
Anyway, I was thinking about using the ENCODER_RATIO component to track
both servo motor speeds and trigger the ESTOP automatically when the speed
error exceeds a certain amount (I will have to play with that value). What
do you think about this measure to at least not worry if the
problem persists?
Thanks!
I had a poor crimp on a IDC ribbon cable do that several years ago, the
handling of the cable made it worse, then 3 pins wouldn't ring,
re-crimping the cable made it worse so I made a whole new one.
Might not be your problem, but its something to check.
