got sick of waiting for it, F200 X&Y F100 Z

lessons learned:
Work must be perfectly flat, not easy on super thin material, any lifting causes the cutter to got a little to deep and the lines get thick fast.
Must use lube! i just gave this a blast with CRC it really helped.
Problems:
The carbide has chipped (red arrows) (

$50US per insert) and i don't know why, there are wear marks on the shaft (white) and i dont know why. i watched the entire job and the shaft and cutter never cam in contact with anything, its got me puzzled.
