I am running Mach 4 on windows 10 with a smooth stepper.? Have been running programs for 4 months,? Machine just started missing steps during the final portion of a pocket mill.? I have double checked the steps per unit calculations and movement is accurate.? I have reduced the feed rates with no results.? Any suggestions on how to solve this problem would be appreciated.??

This morning I finally found a chance to spend some time with the CNC and I think it is missing pulses to the motor, as I notice the Smooth Stepper red lights are blinking at the same time the motor stops momentarily.? I also hear a rachet or buzzing sound if I am jogging and the motor stops driving.? This is happening on both X and Y Axis.? I am new to this type of machine and am not real familiar with this type of electrical setup.? Changing velocity does not seem to make much difference.? I am a complete loss at what do do now.? Maybe my computer (windows 10) or the smoothstepper are at fault?? I have checked the wiring and the voltages to the drivers but didn't check current when I saw the Smoothstepper lights cutting out with the motor momentarily stopping.

missing steps only at the tend of the run? or do you mean missing pulses to the motor/motion? check for motor current and or wire flex connectivity to the motor in question. ptegler |
