That looks horribly out of focus, and 20% for a diode is pretty low for the speed you’re trying to use. I would increase power, lower the speed to 3000 mm/min for a starting point, and check to make sure you’re focused as small as possible.

That also looks bizarrely like the laser is only firing on the ends / transitions, which I haven’t seen before.

yea focus is not an issue… ez-fix

this a 20w diode so 20% is like 50% vs. a 2.5w

i ended up moving to INLINE style with marlin

my first 2 test has layer shift… i think i had the speed to fast. (it was weird because on the first 2 test it layer shifted in same spot in different offset cords…)
