Yes, you're right to point me there. I had a IPM too low on B which I had set to slave to Y. The correction fixed my problem.
Thanks!!!
Which do you think is a better setup: I have 2 screws for Y and want the best performance while also preventing racking.
Should I...
a) "Slave" using G100 axises Y and B for Y?
-or-
b) Connect 2 drives to the one Y axis on the G100?
