I have this issue I haven’t seen anyone talk about. I have a template with 9 squares that I’m cutting for use with engraving coasters. Imagine 9 squares to be cut. For clarity I’ll arbitrarily number the top row as 1,2,3 the middle row 4,5,6 and the bottom row 7,8,9. I’ve ordered them to cut squares 1,4,7 for the sake of this demo. It doesn’t matter, the problem shows up no matter the order.
This is an xTool D1 diode laser with a 20 watt head. I’m running it at 600mm/m and 100% power. In the video you can see that it cuts square nicely. Then it speeds up to travel to square #4. Looks to be about 2,000 mm/m. But, it doesn’t slow down on side 1 of square #4. And because of that it just engraves. Once it changes direction it slows down to the proper 600 mm/m speed. If I’m not watching closely it looks like it cut but I don’t figure it out until I pick up the piece and see that it’s not cut.
This is a simple example. But it does the same thing on very complicated cuttings with hundreds of cuts. Many lines just engraved but not cut. It’s much more subtle if the are small lines and I don’t see it until I pull up the part. I have to then spend a lot of time with an xacto knife to finish the job that the laser should have done.
The order of cutting isn’t important. I can change the order and eventually there will be these kinds of mishaps.
Any suggestions would be appreciated.
