Hi jazz cnc this is my Mach settings.
Mach3 settings
Steps per x 323.31 velocity x663.6 accel 77.708 step pulse x5 stepdir 5
For y 319.82, 431.34, 18.38, 5. 5
For z. 324.14, 348.72, 18.51. 5. 5


I have just checked the vref on the xylotex and there set at 2.16v =1.5Amp so have increased z to 3.42v =2.5Amp I think the voltage is 30v ?

im losing steps when drilling down not when raising the head makes no difference with or without the counter balance.
with power off I can move the head up and down with one finger turning the Handel on top of the motor.
