Hi, Have a problem on my 60w laser cutting machine. It is not firing well (about 50% output). I previously used to cut 6mm acrylic with no problems but now i cant cut though 5mm acrylic.
I have already
- Clean the mirror and Lens
- Realign and calibration on the cutter.
- Change the cooling water and even try to use chlorine to cleanout the tubes.
Attached is the tube when firing ->
Firing is consistance but output power is lessen by 1/2. Just wondering if it is power supply problem or tube problem. Anyone can advice? Thanks.
