Form 3 Lifting Tank, Squealing

Hello everyone,

My company just got a new Form 3 and I am tasked with the setup and maintenance. We used a Form 2 for years, but this is my first time using a Form 3. I removed the thumbscrews and latch as instructed, and followed the instructions on the screen for setup.

I am seeing a strange issue where at certain times during the tank filling and printing process the right side of the resin tank is getting bumped up by some moving component underneath it, and a motor makes a squealing sound. It doesn’t move very far, about 1/4" vertically, but it is enough where a few times it gave a “tank removed” message despite no interaction from the outside.

The print was able to complete and the quality is better than the same print on our Form 2, but now the tank is showing Unused despite being full of Tough resin.

I noticed that the fully installed tank has more play on the right side, while the left side is very rigid. Is this normal? I have removed and reinserted the tank several times and see this each time, despite registering the tank as Inserted.

I am most concerned about the squealing noise and tank bumping, because I’m not sure if I’m damaging the printer by continuing to print. Any advice would be much appreciated.


Hey Ian,

Thanks so much for taking the time to post! I’m sorry to hear you’re getting some unsettling noises!

The best thing to do would be to contact our support team, and provide them with a video of the sound occurring so they get a good idea of what’s going on. From there, I’m sure they’ll be more than happy to lend a hand. :slight_smile:

Contacted support - these are normal motor sounds from 1) the tank lifting to allow the LPU out of the “garage” and 2) the initial tensioning against the tank’s film. Nothing to worry about after all.
