Issue with RPS to RPM was created by gardenweazel
Looking for some guidance on the below error that I get when running my spindle above 9000.

Once I get to 9000 and some change, I get the "Out of range for spindle-speed" error shown in image.

I'm running a HY 24000 rpm 220V mess.

Attaching my config files as well.

Thanks in advance.

Not sure if this is the issue here but there is a missing
connection because the connection between LinuxCNCs
spindle speed command: spindle.0.speed-out-abs
and the signal spindle-vel-cmd-rpm-abs is commented out:

# net spindle-vel-cmd-rpm-abs <= spindle.0.speed-out-abs

This signal is used for setting the PID command:

net spindle-vel-cmd-rpm-abs => pid.s.command

I have this line:    net spindle-vel-cmd-rpm-abs => pid.s.command
approximately 20 lines above this line:   # net spindle-vel-cmd-rpm-abs    <=  spindle.0.speed-out-abs

Fusion 360 uses RPM and it looks as if Linuxcnc uses RPS.

I really need some way that I can use RPM in LinuxCNC if possible.

Or should I just divide the RPM settings in Fusion 360 by 60 and use that so that it matches LinuxCNC RPS?

spindle.0.speed-out-abs is in RPM but is unconnected in your hal fileYou should uncomment this line to re-connect them:

# net spindle-vel-cmd-rpm-abs <= spindle.0.speed-out-abs
