Hello everyone.
Only 50days new chinese 100w 6090 laser and out of sudden curved lines start to get cut with dots. I tried anything I could with settings, but no results. Help!
Please show us what this means. 
I cleaned the mirrors, belts/bolts/cables are ok. Same results, but only at smaller cuts. I quess maybe the motors are low quality… [242190123_253542516656259_32405414502653134_n|205x206]
I think this is a pwm problem
What is your pwm frequency?
