Forgive me if I'm missing something but when I was setting up the machine I had difficulties with the Z axis stalling. I'm wondering if these settings make sense. I have very little options to speed up movements.
Rumba32, TMC2209 (step/dir mode), Z steps/mm 1600, max feedrate 8, travel accel 10, 180mhz.
Is the rumba32 having issues? Or are these setting reasonable?
