M201 - problem with Z axis
Posted: Thu Feb 23, 2017 5:49 pm
I purchase two weeks ago Geeetech Prusa I3 M201 printer .
Unfortunatly till now i do not solve problem with Z axis . When axex move up or down they stall , motors humming and then after few second moves .
Do they booth motors (42SHD0034-20B) have only one step driver A4988 ? Can I adjust a Vref (on what value) that motors have more power ? Which driver on board GTM32pro is responsible for this ?
Or maybe is solution to by strongers motors (what kind or type) ?
In the proces of build this prunter I allready need to make a little bigger holes on booth Z-top mount because without this the lead screw can not turn with hands .
I have mechanical knowlege and I check all parts many times but unfortunatly can not find real solution for this problem .
Can anybody give me a tips ?
