I’m cutting a lightweight fabric material and am looking for suggestions speed vs power and a question about not always burning through the material.
The laser i’m using is a 7w JTech laser running at 12.5% and 5 inches a min. I’ve also created lead-in cuts to minimize the initial burn through on the part. Overall I’m pretty happy with the results but I’d like to get it a little cleaner/less scorching and more importantly at my current settings sometimes it cuts perfectly but sometimes it doesn’t start to cut though the material.
Which usually results in less burning. Faster cuts and higher power or slower cutting and lower power?
More importantly at the current setting sometimes it cuts perfectly but other times it can take up to .10" before the laser successfully burns through the material and starts cutting the part. It only does this sometimes. Is this because I have the power dialed too far back?
Any suggestions would be greatly appreciated.
