Loud clicking sound and check mixer error

I filed a case with Formlabs. When they got back to me after having sent them a video they came up with the fix that they needed to turn the electromagnet strength down and it would solve the issue. This was after having me check my pre-form firmware update to make sure it was all update. Also had me check the firmware on the printer to make sure they matched.

After having done this they remoted in to my printer, turned down the strength of the magnet. After that I needed to reboot the printer for it take affect.

This fix worked for 3 prints. Then it came back and it has been there ever since. It is not quite as prominent as it was before but is still there nonetheless.
