Quality of 3D carves

General

I’ve had my 1F Elite for a few months now. It has the PWNCNC ATC spindle.

I’ve noticed that my 3D carves are not very smooth. I’m using a Taper ball nose bit at 10% stepover. I get areas that are pitted and grooved and at random spots the height of the carve changes. I have a smaller leadscrew machine that produces better results than the 1F using the same bits.

The 1F is on a torsion box so the base is solid. The spoilboard has been levelled.

Everything appears solid. I’m stumped. The STL doesn’t have these artifacts in them and when carved on my other machine, these artifacts don’t appear.

I’m looking for any assistance people might have. Thanks in advance.

Have you played with the stepper resolution? I think they ship from Onefinity at 400 ppr. I’ve seen tests showing different results with profile cuts on circles and end grain at different resolutions. 2000 ppr looks a lot better than 400 ppr. Just a thought. I’m sure it could be other things as well.
