Last update, after upgrading the firmware and cleaning everything from the tube output down to the lens it is finally cutting again. I don’t know if I can consider lightburn’s power output anyhow, since at every material test I run, the results looks a bit random.
One last update: today arrived my new tube (80w), the PSU’s LCD with potentiometer and an analogic ammeter (30mA). All can say is: new tube, new life! Now I can control the current through the PSU LCD’s potentiometer and the reading is spot on with the analogic meter. The new tube’s working range is 6-25mA, I made some test cuts with the tube at 14mA and the speed more than tripled comparing to the old tube, now I am cutting at 20mm/s instead of 6. It’s crazy!
Thank you @jkwilborn for all the help! Now let’s get back to work!
