I was doing my first cut with the MPCNC
so I was using a 1/4" double flute end mill on plywood
I had a couple spots when the bit was travelling at about a 45 degree angle across the x and y axis
that resulted in some chatter of the end mill.
What is chattering generally an indication of?
the rest of the cutting was very smooth, no burnt spots, didn’t hear the spindle bog at all.
the “saw dust” was very fine… not sure if this is good or bad?
I’m using a 1.5kw spindle… spindle speed was 28,000 rpms
x/y rate was 12mm/s
