I have been cutting a lot of signage letters lately. One of my clients wants really clean 10mm clear acrylic letters. He does not like the little stop start line. e.g. when cutting an "O" I get a distinct line on the side of the character where the laser starts and stops.
Is there a simple method for getting rid of this? I am not keen to edit the files as to define my stops and starts with a lead in.
On a side note: When running a 1 hour+ job, I notice my power drops quite a bit too. I can cut 10mm acrylic with a cold machine at 100% power x 2% speed. When the machine is hot I need 100% power x 1.3% speed. I also noticed the cooling fans are running at full speed. It makes sense that the laser will lose power when it is hot as the laser will thermally/optically expand and electrical efficiencies drop too. I have readjusted my settings to 80% power x 1.3% speed and it seems to work good but I have not done a big job yet. The fans continue to modulate rather than hitting full speed. I also cleaned my filters but they were not too bad.
Cheers
