I am hoping someone can help me, because my laser cutter is driving me insane.
I have spent days leveling the machine, aligning optics. I have replaced, my tube, my power supply and my optics, and still I cannot get my machine to work right.
My main problem at the moment. I am cutting pieces 830 x 350 out of 5mm clear cast perspex on my 1300 x 900 bed. I am cutting along the 900mm length to minimize the number of points the laser crosses the supports as it create flash points in the material. The laser seems to be cutting the top 70 - 80% of the piece fine, but the bottom 30% is not cutting all the way through. I am then having to re-cut that section and it is ruining my edges. Its for a display case.
I have checked the alignment at the 4 corners of the bed and all seems to be spot on. I have checked the distance from the cone to the bed and there is virtually no difference in distance across the whole bed. I am running the cut at 7mm per second, which is far slower than what I was getting when I first purchased the machine. (It worked ok for a few hours I would guess.)
I can run a 20 x 20mm test cut in that corner and it will cut through, then when I run the full piece it doesn't cut through.
I just don't know what more to do. At the moment, with the way I am feeling I just want to finish this job and get rid of the machine as soon as possible. I have not been able to run a single job on this machine without having to redo work since I got it three years ago.
