Hi,
I'm new to this forum, not new to laser cutting and engraving. I have been doing this since 2011.
I started with an affordablye Ch laser, now I have a BRM, bigger, stronger, higher quality.
As I mostly cut and engrave parts for modelbuilding, I experienced the following with my new lasermachine.
Example :
Job with 2 layers
Layer 1 engrave bitmap sp 500 power 30
Layer 2 cutting sp 20 power 18
When I only execute Layer 2 : perfect result, material cuts nicely.
When I execute Layer 1 - Layer 2 (cutting after engraving) : material not cut completely. The early cut lines are bad, the later ones become better but not acceptable.
I can work around this by adding an extra layer in between, letting the laser draw some lines, outside the original work I need. But this is not the way it is suppose to work.
My first machine did not behave like this. It seems the laser has to rest a little bit before using lower powersettings after engraving.
I can also higher the power but this means more burning and also cut lines being not as fine as wanted .
Anyone experienced this?
info : Software RDCam V6.33.44
Thanks,
Paul
