General Mach Discussion / Mach 3 and MSD880 microstep driver settings

« on: February 02, 2017, 03:07:53 AM »

Hi all just building my first CNC setup so maybe some stupid questions:
first try with moving all axles all motor`s become very hot setup changes current down now seems ok

Mach 3 not tuned fully yet
MSD880 microstep drives for all 3 axle
and Motor type  FL86STH156-4208A-H coils in serial
set at dynamic current setting 3.5amp microsteps set to3200 not sure if that is good or ?
in mach 3 not sure what "mode" under ports and pins will be correct MAX CL mode or one of other ways?
when jogging x or y or z the motors sometimes stopps fully and on mach 3 it looks like they are moving and a 200mm move is only about 2mm so need some guidiance what and where to adjust

thanks in advance
