spindle via step/dir servo and Mesa card

For spindles, STEPGEN_MAXVEL needs to be in RPS
and MAX_VELOCITY needs to be in RPM.

The comments from pncconf should be changed for spindles.

Thanks. It works now, after I changed MAX_VELOCITY / MAX_REVERSE_VELOCITY = 28000.

I still get the potential StepGen clipping warning, though. Is there an option to disable the warning for a spindle StepGen?

What is your STEPGEN_MAXVEL setting?

Fixed. Thanks Peter

I double checked things and was confused when it was set to 28000.I had some issues with the Spindle in Step/Dir, going from 2.8 -> 2.9, so I thought I would generate a test machine with Pncconf Wizard and copy the Spindle section from the example machine.

Pncconf Wizard for 2.9 has a bug in the Spindle StepGen:
setp hm2_7i76e.0.stepgen.03.maxaccel [SPINDLE_0]MAX_ACCELERATION
setp hm2_7i76e.0.stepgen.03.maxvel [SPINDLE_0]MAX_VELOCITY

Correct is:
setp hm2_7i76e.0.stepgen.03.maxaccel [SPINDLE_0]STEPGEN_MAXACCEL
setp hm2_7i76e.0.stepgen.03.maxvel [SPINDLE_0]STEPGEN_MAXVEL

PS: I submitted this as an issue on GitHub.

Thanks for submitting the bug report

(28000 RPS at 800 steps/rev is about a 22 MHz step rate
so not surprising that the driver complains)
