Hello!
First, I must say this is the most helpful forum on the internet if you have questions concerning lasercut! I own a machine since August this year and you guys answered a lot of my questions. This time, sadly, I am concerned I am dealing with a real big problem.
The machine I bought has the following specs:
- Swordsman laser
- 130W z6 Reci laser tube
- 90x120 cm worktable
- Focus lenses: 50.8mm and 63.8mm
- RDCAM 8.0
- Koi compressor as air supply
- industrial chiller (temp: 18-20C )
The problem is the machine has less power than it had before. I can't even cut through 3mm wood. This is what happened:
First I cut a prototype for a table in 3mm plywood with the 50.8mm lens (speed:30, pow:70), without any problem. Then I wanted to cut the actual table in 8mm plywood, meranti. I swapped the focus lens for the 63.8mm lens and used these settings: speed:7 pow:90. After 30min of cutting the cut changed to a blurry engraved line. I stopped the machine to check what the problem was.
At first I tought it had something to do with the mirror allignement but after checking the focus lens I realised the problem was much bigger. The lens broke in pieces and looked black, probably because it got to hot cutting at 90 percent and slow speed.
After this I put the 50.8mm lens back in, cleaned and alligned the mirrors (for 2 hours, did a total revision). I did a test trying to cut 3mm plywood (speed:30, pow:70) and it wasn't even close to cutting through, even a second passage did not do the job.
What do you guys think made the first lens burn up and is it possible I fried my laser tube? If I pulse with 80 percent power pulse meter goes up to 40 mA. But the laser seems to have less power.
Hope you guys can provide me with some possible answer.
Thank you!
