Re: [CAD_CAM_EDM_DRO] Re: Gecko G201 and Drive Current ?

Mariss,
Well I'll try that next, although a Resistor in the 0V return at the PSU is not going to lie either.
I just tried rewiring the motor to series connection and adjust the Sense resistor to 3A (33K)
But it does not improve things at all.
Best Regards
Hans W
