Bad Print Head?

Possibly a bad head from a scratch or something dragging under the head. Try cleaning it. We've experienced small pieces of anything [belly button lint, assorted mouse droppings] getting on the head, not letting the resin go down properly.

Not really on the 'droppings', but small things can get tangled in somehow and prevent proper firing.

 

Of course you've tried cleaning with Isopropyl alcohol, correct? If that doesn't do it, you may have a blown ceramic print head. It will only get worse.

Be prepared for a $3000. repair bill from Gerber. Plus you have to crate the machine in their "own approved crate/box" or they won't accept it. Ship it to the east coast and wait. That's what happened to us about 4 years ago. At the time, we had their warranty in place, which saved us a bundle.

Good luck, maybe it's something simple. Hope so.
