@Brandon_Satterfield For some reason mine will either run 11000rpm or 24000rpm but nothing in between for now.
If all your P0 settings match the video comment, namely P0-024 then we may have a GRBL issue.
@Brandon_Satterfield Ok, what do I need to do with that?
Give me a few min Jamie. Let me look at a few things.
Loading GRBL is super simple.
You will put a laptop where the rPi is, if you have the arduino IDE installed already it’s a 4 min process.
@Jamie_Wilson set $30=26000 & $31=400.
Run through S10k 15k and 20k reading Hz x 60 and compare. That’ll narrow down if it’s time for a new GRBL load.
@Brandon_Satterfield above 12k it is the same 368 hz
@Jamie_Wilson alright may be best to just try a fresh GRBL load.
I will load a GRBL file in the forum shortly, it will have everything preset for you.
In the meantime check out this:
I made a post that has the GRBL file here:

@Brandon_Satterfield ok that seemed to work. Tried 10k-24k in 1k increments and hz went up each time. Maxed out at 24k @ 365hz. Thanks for your help!
Earlier you said 386hz was almost 24k rpm. Now max is 365hz set to 24 k rpm. Will that work out ok and be close?
May need to change $30 back to 24k.
Also make sure P0-24 is 400. there is an overshoot. The M1 kicks out 10.6 volts at S24000. This is the new max, so there will be slightly higher RPMs then read through S command.
Working on a solution.
Glad to hear you are up and running though!
@Brandon_Satterfield played with it a bit. Set$30 to 25k and now 24k is running 382hz
