Hi there, I’ve used this material:
https://www.ebay.co.uk/itm/162577376592
And used the settings he mentioned, worked perfectly.
For the engrave and cut I did two passes ! (the cut just to make sure) or you can try reducing the speed of the cutting part.
Settings:
Power: 70%
Speed: 340 speed
Two passes
Cut :
Speed: 200
Power: Full
Maybe two passes.
