I’m having issues with my laser focus being inconsistent specifically when cutting silicone 0.06" thick.
I’ve manually set the focus height and sometimes it cuts perfectly. Many times I have to stop and restart the cut or turn off the machine.
Cleaning the lenses is not the issue.
I’m also manually setting the focus height but it is definitely changing between cuts as you can easily see the cut width being much wider when in error.
It’s now part of my process to have a number of small test cuts in every image in order to stop the cut before it gets to the actual project.
