Hello friends!
Im having a problem with my 1390 Co2 Laser machine when i try to engrave photos.
Im using 25% of power in one 100w reci w2 tube.
Problem is that laser starts to engrave for 20-30 seconds and after power drops to much and not engraves nothing.
Power supply shows around 0.5 to 0.9 ma with 25% power.
I did some test with 50-60% and shows around 11 to 15 ma.
With 80% reaches 27 ma.
Another strange thing is that i tried to engrave txt with 25% and all goes fine.
I dont know why with bmp images happens this.
Thnx in advance!
