Hi Joe,

About the stalling, have you tuned the motor current PIDs on the motor drivers? I have EM806 rather than AM882, but I think the process is essentially the same, connecting up the RJ11 port to the COM port on your PC and running the "protuner" software.

This will make the drives change how they apply current to your motors to match them better, and allows you to set the motor current more accurately than the dip switches. Improved the speed I could get from my machine quite a bit.

Thanks Andy,
I’ll have a read about how to do it, but sounds good if it will help with the stalls. Only seems to happen on x which is a big NEMA 34 turning two 2005’s via a belt. If I was buying screws now (rather than 6-7years ago) I’d up the pitch.
