60W Laser Engraver Does not cuts uneven way in x axis

[cdmc]

Hello everyone,

I have a 60w CO2 Chinese laser engraver for a year now, when I got it was ok and cuts evenly, I mean that was cutting a 3mm plywood for example with 20% of power in x axis from 1 to 700 (left & right side of the machine table).

Recently I discover that needs more power to cut the same plywood for the one side to the other for example till the middle of the table is ok with 20% power after that need more power and at the end fo the table ex. 650mm does not penetrate the plywood is just a line like scratch.

I try to calibrate again the mirrors but seems ok I believe.

I don't know what can be the problem, and I need to cut more than 600mm

Any idea what the problem is ???

Thanks in advance

Christos

Have you cleaned the mirrors and lens? I use IPA and a Cotton Bud on mine. Is your extractor working properly or do fumes hang around the cutting area?

I did but It doesn't help. Also the extractor seems that is working fine.

FIXED!!! Alignment of the mirror was the problem.
Thank you all !!!
