Laser Cut Acrylic
Question for anybody with a Laser Cutter. Any idea what caused the vertical lines/chips in this photo?
The chips are from the bottom of the cut.
Thank you

Getting bounce back, so the laser it almost cutting twice on way back up also. We get round this by putting small off-cuts of acrylic underneath so almost floating the peice you’re cutting up 5mm and this solves it for us??

This seemed to work. Thank you

Thanks Craig. Will have a play and see if that helps!

I guess you are just starting up using the laser David? Too much power + raise the cutting piece. I almost never use the honeycomb bed.

That’s correct. They’re not exactly ‘plug and play’ are they? 😀
Had a little play this afternoon with some success. Raising the material helped and as you say I think I had the power much too high!

Get a small notebook.
Play with different power and speed. You will be surprised how different the quality is when tuning your machine.
When happy with result, write it in the book. 5mm white acrylic, 35 power, 15 speed for example.
And like this for all materials and thicknesses.
Will come useful another day.
P.S. NEVER LEAVE THE LASER ALONE WHEN OPERATING. ALWAYS KEEP AND EYE ON IT.

A quick word of warning. Don’t turn your back on it. Treat it as if it’ll go on fire anytime. We’ve had 2 fires in our in the last few years. Thankfully I caught this one in time! Cutting perfect until it got to the back of the sheet, then decided to incinerate it. Also “Deepnest” will be your friend for saving material – https://deepnest.io/

That is a handy bit of Free software, David. 👌
Signlab has its own “block nesting”, but at a glance, the Deep Nesting does a better job, so could be a good additional tool to have, if and when required. By this I mean for routering, cut vinyl, rather than just laser etc. 🙂👍-
100% Robert. I stumbled across it on a Lightburn forum. Never fails to make me smile when I see how it places parts in ways I could never have though of. We use the Adobe suite and Onyx so have no built in nesting tools there, although our CNC software has.
