Hi all,
I have recently been having problems with my 60W Chinese laser cutter i had it for about 3 months and the tube went which i replaced however since then i have had to reduce the speed and power levels to be able to cut.
I have re aligned the mirrors about 3-4 times trying to rectify the problem but it just seems to be getting worse.
I can engrave with no problems but when i try to cut through the material (3mm MDF) the laser struggles even at slow speeds.
The other thing i have noticed if i raise the power level to above 40% the laser fires but the laser only appears out of the nosle for a short time then disappears.
If anyone can think of why the laser would be doing this please let me know its driving me crazy.
The thaught i currently have is that there is something wrong with the lens / mirrors as this is the only thing between the laser tube and the materials
Thanks in advance for any help
Dave
