It saved me a lot of time. Thanks. Though the extruder is not operational yet I was able to test the stepper in RegG by modifying the gcode: M108 S255 M108 R100 You need the R code to set the RPMs but you need to set S for the PWM value first. Once these were set the motor ran as expected (as well as expected for a simulation). Hope that helps... Rick Hey Zaggo -
