This is a laser cutter running awc608 laser controler,

The steps it's set to now I can move back and forth nice, but if set them lower they just move 3mm and stall, so not sure if this is through psu needing bit more power, or turning amps up,

The 48volt psu I got as a ajust screw, if this is turned down to lower volt would it hurt the psu or are they ok,

Thanks jazz kev
Ok I see on the controller front and while I can't find the Frequency this controller works at I'm sure it will be more than 25Khz so lack of pulses shouldn't be problem. Still However lowering the MS shouldn't cause stalling motors provided you set it up corrrectly in the controller which might be your issue if not doing this.

The motors you are using are relatively high Inductance so will require more voltage to spin fast but still with 100mm pitch they should easily reach 500rpm if wired Bi-polar parallel.
If series wired then this could be your issue because torque drops away quickly as RPM increases and with only 36V may struggle to spin much more than 500rpm.

Do the Motors have 4 wires or 8 wires.?
