I’m glad to hear you have the new spindle, it didn’t sound like a spindle issue but that should eliminate that as a cause.
I would be afraid to do 1/16" (.0625") cut depths on padauk. Using that same bit on MDF, I have to take fast, shallow cuts (.024" at 64 ipm), any deeper and it chatters. I’d suggest the reduced speed and depth tests I came up with above, maybe even take it down to 60% instead of 75%.
Spindle RPM isn’t going to matter much, the 24V spindles will slow down when they encounter resistance. Not enough torque to take big deep cuts. They’re good for shallow cuts and jobs where you’re not trying to get it done ASAP though.
I didn’t get back to this mess as
soon as I had wanted. We had an emergency with one of our kids. So we spent the
weekend at the Vet’s.
Anyway, late yesterday I put the
meter on the pots and found that the Y & Z axis motors were way out of
whack. Now with those two running smoothly, the spindle sounds a lot better and
is carving at a steady depth. I spent over 20 years working on heavy equipment
so this remedy confuses me, but it worked!! Ockham’s razor. So thank you for
that video on adjusting voltage to the stepper motors.

Glad you were able to find the issue and fix it!
I am having this same exact issue. I will have to watch the video later. I just wanted to say that you are not the only one having this issue. I am glad to find an answer because i was as confused as you were about what might be going on.
