Form 3 Mixer Arm not moving, LPU grinding sounds


#1

Hello,

I’m having a new issue with my Form 3. During a print the mixer arm doesn’t move across the tank at all. Also when the LPU moves it makes a grinding, almost screeching sound. Has anyone run into this? Earlier I had to clean the LPU glass due to a piece of lint causing print issues and it ran fine after that for a couple prints. I also updated the hardware and Preform software.

Any help would be greatly appreciated!!

Yep

You need to clean and re grease the X lead screw.

Thanks! I’ll give that a go once the grease comes in the mail.

I am having exactly the same problem as you, for sure its not a problem of cleaning.

How did you do it?
What kind of grease did you use?
Could you send a picture what has to be cleaned and greased?
Thank you.

How did you do it?

I cleaned the screw with a toothbrush, then spread grease along the screw

What kind of grease did you use?

Lithium Grease

Could you send a picture of what has to be cleaned and greased?

If you remove the tank the x-lead-screw will be in front of you along the back wall of the printer.
