UPDATE: Mixer just decoupled on my 3rd print with the replacement 3+. Its stuck under the build platform, and the printer is continuing to print…because why not? Still using Tough2000.
Ordered some 1500, hopefully it prints more reliably…

Hi @nauticalknowhow,
I just wanted to reach out and let you know that your best bet would be to open a Support Ticket if you are still having any issues with the mixer.
Also had the same issue today. Wanted to supply a data point that I was also using Rigid resin (4k) and it was very cold so it took ~50min for the printer to heat itself up to the mix temperature. So it seems to be relevant to the temperature and kind of resin, which eventually lead to difficulty (force needed) to mix the resin.

This is a great callout; especially with a resin as viscous as Rigid 4K, the heating process will definitely cause the length of pre-print time to vary. Without getting the resins to our target temps, they would not print properly.
Hi! I just wanted to pass along our youtube video explaining how to work through some common Mixer Check Failure troubleshooting steps in case it helps anyone experiencing this issue!

Mine is doing the exact same thing and I intermittently get grinding noise too ! This is on a lpu with only 11 hrs!
Hi @Stagman! It’s possible that your Form 3 is due for its x-axis maintenance (see the full schedule of maintenance here). Over time, the anti-backlash nut on the printer wears down, and can leave debris along the x-axis lead screw. This can lead to print failures and abnormal noises due to an increase in friction during printer movement.
If you haven’t given it a try yet, I recommend doing so. We have a process video on the Formlabs Support Youtube channel for this maintenance, so I hope you find it helpful!
