When running two Z motors on different drivers, the acc and current settings apply to both motors if they are mapped as Z?

ok, thank you for the answer. i have set the current to 1500mA in the config. I have two z motors. First i tried running them in series, did not get desired result, so now i am trying running one of the z motors on E1. Sometimes the motors seem fine for a couple of seconds when jogging, then they start again.

Also, when changing config file on the web interface, the board reboots. but is all changes active or do i have to power off also?

Hello, i am sure this question has been asked many times before. I have previously had great success upgrading my delta printer to a duet board. it was some tweaking in the config file to get it running, but now its running great. So i wanted to upgrade my chinese cartesian to a duet also, but I am going mad tryin to get the steppers to stop stuttering. I have tried to make a new config file multiple times, but i dont see any constistency in changing values and when the motors stutters. Right now my X and Y seems ok, but my Z motors keep making noise, stutter and not going where they are supposed to. Checked for voltage drop, changed to better sd card. I am not sure what settings i am supposed to have on current on the motors, since i cant find the data sheet for my motors. (SL42STH40-1504A). Anyone have a pointer where to look?
