I am having MIXER CHECK FAILURE’s on my FORM 3
The wiper arm breaks loose in the front and gets kicked out of position.
Here is a link to the video showing wiper getting knocked out of position.
This started to occur after about a dozen successful prints.
I completely cleaned and all resin out of 2 tanks and washed the tank and mixer arms.
No debris or residual particles were present.
Formlabs support had me remove the LPU to examine the magnetic couplings to insure they were not loose or anything blocking them like a cable. Sadly I somehow ended up with a cracked ribbon cable to the LPU and I need that replaced.
I did a check of the magnetic hold of a wiper arm on to the LPU placing a clean wiper arm on top of the LPU and it magnetically locked in place.
The thing I noticed was the magnetic hold on the back end of the wiper to machine was very strong yet the hold on the front side was weak comparatively speaking. I reversed the wiper arm to see if the results were the same. And it is clear the front magnetic hold is not anyways near as strong on the front coupling. So this may be a mechanical calibration issue.
If you watch the video in the link you can see the check I did to show the magnetic strength test of the wiper
I submitted a request for help on Monday and 2 follow ups and here it is Thursday and still have not heard back from support. I have the Pro service plan and extended warranty.
I am creating this as a topic in case anyone encounters the same issue. And the check I did should help decipher if the magnetic hold of the wiper to the magnetic couplings is solid or not.
