At the moment i have set 3200 microteps per rotation. Tried lower...

There is not much of tuning options. 4 switches for microstepping, 1 for spinning direction and 1 for 'up edge and down edge'. Not sure what the last one does.

150rpm sounds correct, but motors torque is not the problem as Y axis can move 10m/min. Yes, these are nema 34 with 3.8 inductance and around 7A. Connected directly. I am pretty...

Yes, sepparate drivers. Tried to run them freely and with ballscrews disconnected from gantry. No problems.

CitizenOfDreams, thanks for an answer.
