last night i switched from usg to pic sender because of larger file handling. Question is how do i get the spindle to automatically come on when i send the file?

You must have a M03 S18000? in the beginning of the Gcode file to send the PWM on Pin 11 high to turn the spindle on. Make sure you have “Send M03” selected.
I highly recommend selecting “Use Save Z” and set a retract height so if you Cancel a job your tool will retract before it travels back to your X&Y work Zero place.

Thank you will try later.
here is what the start of the code looks like
T1M6
G17
G0Z0.4382
G0X0.0000Y0.0000S28000M3
G0X-2.4992Y-2.4983Z0.1250
G1Z0.0400F10.0
X-2.0992Z-0.0274
X-2.4992Z-0.0947
G1X2.5000F50.0
X2.5000Y-2.3276
X-2.4992
X-2.4993Y-2.1552
X2.4999Y-2.1552
X2.4999Y-1.9828
X-2.4993Y-1.9828
X-2.4993Y-1.8103
I just tested that code with a M05 added at the end using grbl 9J and my laser came on full power and followed the paths and then the laser turned off at the end of the file. Your spindle should be coming on with the S28000M3 also.
