Hi! I,ve been working off and on with this for ~6 months. No success. Please see my system below.
Win 10, Mach3 (3 axis mill), ESS smoothstepper, C25S BOB (CNC4PC), HY DIV-268N 5A drivers. 4 wire NEMA 23 motors and 36V P.S.
The problem is with all axis. The on screen jog and Gcode entry do the same. Wiring has been debugged. driver tests show 5V one direction and 0V the other. Current draw is ~50ma one way and 0ma the other measured DIR+ to DIR-.
Uninstall and reinstalled Mach 3....no help.
I really need a solution.
Thanks......dt
