Got this printer 2 years ago and it worked great for about 6 months. Then it consistently failed on every single print, it can’t get past checking for debris. The flex build platform is colliding with the mixer on every print no matter what the material. Specifically, it lowers the build platform, moves the mixer arm, then lowers the build platform. That’s when it hits the mixer arm and has this loud clicking sound.
I was able to alleviate the issue for the past year by setting the z-offset to 540 um. But I performed a build platform alignment and now even with the z-offset maxed out and the platform still collides with the mixer when checking for debris. I have checked this with a new tank, mixer and a different build platform.
I suspect it’s something in the platform sensors or the firmware because when I could get it to print, and I printed directly onto the platform, no raft, the first few layers were absolutely squished, even with the z-offset high.
Any recommendations? Otherwise I’m strapping to it and leaving it outside Formlab’s offices.
For both Error 1.1.6: Mixer detected debris and Error 1.1.7: Build platform detected debris.
Neither procedure produced any different result. I did submit a support request in Nov 2025 but I never heard back. I figure it was because we don’t have a service contract (it expired last year).
I’m a Customer Support Manager for Formlabs, and I’d like to discuss how to get your printer working again with you, as well as your previous Service interactions. I’ll be reaching out.
I considered that and took the flex plate off the build platform and reran the align build platform. But it did not help, the build platform still crashes into the mixer.
