Settings for thick black acrylic

Im trying to engrave and cut on thick black acrylic and the engraving is faded and the cut with 2 passes doesn’t even go through half of the acrylic . NEED HELP

Is it the thick Proofgrade Acrylic? (1/4" thick)? If not you can probably use the settings for Thick Proofgrade Acrylic, assuming it is a similar thickness material.

If it’s any thicker than that, you’re going to need to do some tests to determine the correct settings, and watch it when it prints so that it doesn’t flame up.

It is the proofgrade 1/4 thick acrylic.

That’s a problem. Sounds like it might be a power fade or dirty path.

How long has it been since you cleaned all the optics? (Instructions for that are listed here if it’s your first pass at it.)

Thanks for letting us know. I’m sorry that your print didn’t come out beautifully!

To cut successfully, there are three important things to check. First, your material must lie flat. This requires a clean, properly installed crumb tray and flat materials. Second, there must be no obstructions, dirt, or damage preventing the laser light from reaching your material. Third, your design must be set up properly - for example, with lines that are fully on the material and that are set to cut. It’s hard to know which issue might be affecting your print, but if you follow the instructions in the cut-through troubleshooter, we’ll be able to get to the bottom of it.

Once you’ve inspected and cleaned, please try another print. We included an extra piece of Proofgrade Draftboard with your materials shipment for troubleshooting. Please print the Gift of Good Measure on that Proofgrade Draftboard and let me know the result. If it doesn’t print well, please let me know the date and time of your print and send photos of the front and back of the print.

It’s been a little while since I’ve seen any replies on this thread so I’m going to close it. If you still need help with this please either start a new thread or email support@glowforge.com.
