Not cutting through on PG materials

All proofgrade materials are cutting but not through, blue acrylic ornament I just printed = total disaster and waste of materials, and I cut myself on the shards. extra 10-20% worked on draftboard but wtf.

For the future, before you pull anything off the bed, test to make sure the cuts went through - no reason to waste materials!

For this issue, they’re going to want you to cut, note the time, and post pictures of a Gift of Good Measure (GoGM) on proofgrade (PG) materials. Post that info here and if we can’t help, support will be along ASAP. You can request they credit you for PG that didn’t work as expected.

Also, have you cleaned your mirrors/lens lately?

I am doing a GoGM now on medium Draftboard.

Also, is it normal for the image to off set when the final scan happens?

Yes, but not that much. Have you run a Camera Calibration at all?

fresh from the factory three days ago, I have cleaned the lens but not the mirrors, and have not run a calibration

Let’s figure out your cutting problem first, but then it’s worth running the calibration. Anything under 1/4" is considered within spec, but with the calibration most people are sub mm.

Question - the board has 2 other GoGMs that look like they cut through fine - when were those run?

Any chance you put the mirror back in upside down? The “bowl” should go up into the head

unfortunately, they did not cut clean until I lowered the speed to 165 and even then did not cut the rear masking

Lens is installed correctly

That’s the last I can think of - someone else may chime in - or soon support will show up after they’ve checked your logs on the back end to see if they can see anything happening there :frowning:

The thing with draftboard (or any natural material) is it can swell/shrink in humidity - so sometimes the altering of settings is required depending on where you are, but as this all started with acrylic that’s not the case there! If you can get a GoGM onto one of the broken acrylic pieces that might be useful info too. You’re going to love this machine once you get this settled, but in the meantime it sucks.

Thank you for being such a great community, I’ll get this dialed in soon and cranking out wonderful pieces.

I have to go, but I will be back tomorrow to finish sorting this out.

We got ours 2 days ago and are having the same issue, doesn’t completely cut through anything. I would recommend going through the posts similar to your issue and use their tactics,; cleaning, changing settings, using magnets, etc so when you are in talks with customer service they can see what happened when you tried each of those things. I tried them ALL before contacting and hope that made it easier to see the problems but still no resolution for us yet. Good luck

@magoulasmg, I am sorry to hear you are experiencing a similar issue. We can only address one customer’s issues per thread so please start a new thread or email us at

I look forward to your reply.

I would like to utilize the forum for response please. I have uploaded front and backs of two GoGM projects here. I have not received an email from you yet. Which addition photos / info would you like me to provide you with?
