How would that be done in the HAL file? And BTW, Peter could probably explain why but when I bumped the RPM up to 100 and then looked at the velocity output and it mirrored the 1 RPM velocity profile. Just at higher rate. I'm guessing that even though the HAL rate is 1mS inside the MESA it's likely 10x or even 100x that so we get a way more detailed waveform that then is repeatable 1mS interval in LinuxCNC.
