Hi, tk421
Look under Config, Motor Tuning, Mach's default settings are around 2000 Steps Per, 120 Velocity and 10 for Acceleration.
Try setting 500 Steps Per, 50 Velocity and 5 for Acceleration for X, Y, Z, Don't forget to click "Save Axis Settings" for each axis.
Steps Per (Amount of Pulses to move 1 inch / MM), Velocity ( Max Speed without losing Steps), Acceleration, (From no movement, Start to
Stop speed, without losing Steps).
Hope this Helps, Chip
