Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

[JOGARA]

8mm DOC, 0.5mm max stepover.
Cut fine, no noise, looks like I can go deeper.
Going to attempt 1mm. Can always pull it back.

This is much better than the 1hour+ than before. Down to 15mins now :)

The spindle is out but only by a hair. I can feel on the contour pass a slight line going around 2 sides of the part.
I have lowered the contour pass to take 4 depths instead of 2, this fixed that problem last time.










I am also getting this again on the contor. I have a 10mm finishing overlap. But I used default lead-in. I have upped that to 2mm. Hopefully that stops that.



And yes, I forgot to go -0.1mm on the contor pass so there is a bur going around the bottom of the part. The roughing pass went -0.2mm, so I normally set -0.1mm for the finishing endmill.
