hello friends, I have a problem with mach3 home coordinates.

X-axis Shifting during job, and when program finished the X axis shifted to +X about 1-1.5 inches.

I have uploaded designed file and finished job.

how can I fix this problem?
anyone can help me ??

Try reducing your Velocity and Acceleration settings by 50% in Motor Tuning and apply the changes for your X axis. If this resolves the issue then increase your Velocity and Acceleration setting in small steps (using 'trial and error') until you get the best performance consistant with reliable operation.

Tweakie.

Could be, also, a polarity of step pulses (active high/low)
