program stops: says "moving" (answered)

Stops on line n22. First move G1

hello. do you have a working spindle encoder connected and configured?

No, I had it configured without the encoder. Will feed per rev not work without the encoder?

[diycncscott]

Feed per rev will only work if there is an encoder connected because movement is slaved to the spindle encoder.

You could easily calculate the inches per minute feedrate and use ipm instead but that kind of defeats the purpose of what a feed per rev move is supposed to accomplish which is to move an exact amount directly correlated to the actual revolution of the spindle. If the spindle loads up and slows down a little, the feedrate also slows to keep the finish/load even.

desired feed per rev * rpm = ipm

Thanks Scott.
I understood what it meant, I just didn't realize it was tied to the encoder. At least now I know it wasn't my post processor changes!
