There have been 2 tickets created dealing with the critical dimensions for sensor mount and decoder wheel.

T5873 Decoder wheel & T5874 sensor mount

@oliver
the graph for the filament sensor reads that the target value is 10.5, Currently the value is 10. Correct me if im reading the graph wrong though

@west @oliver the measurement I took off those parts was not off of the critical height of the part, my apologies, it was off of the same back part of the piece.

I think the data chart was used generating based off the 10mm but ultimately need the board to sit further from the magnetic wheel which would be the 5mm part.

@west The upper and lower control limits were chosen what was failing on a filament sensor

@west I am pushing some concept changes to this branch for the bearing mount and sensor mount that I think will help with this issue. The adjustments were made using blender; however, initial testing has been successful for ensuring consistency between the circuit and encoder wheel without contact between the two. Let me know what you think.

@EricNugent what changes were made? is it v1.3?

@west should be v1.4_inserts-removed and the bearing mount absorbed that parts inserts.

@EricNugent do you worry about the bearing mount breaking?

@west it is possible, but the geometry modifications will strengthen the bearing mount and prevent the bearing holders from bending towards one another. Some of the benefits include getting rid of problematic overhangs on the bearing mount itself, we can likely flip the orientation of the sensor mount and increase the layer height to speed up print time as well.

I pushed changes that you recommended. If this gets apporved, the insert drawings will need to change - we will need to remove PP-IS0080 because there wont be any inserts in that part, and we would need to create a new drawing that would show inserts for the bearing holder. The bom would need to be updated to show the insert changes and parts to be re-weighed

Sounds good, I will get the slices working and drop off a couple for you to test. I think we can change most of those things pretty quick in this branch and push it to master once everything looks good.

@EricNugent have you had a chance to test these changes out?

@west seems to work pretty good from the 5 I have tested. The Alpha circuit boards had some issues changing the pin state but the updated red dot circuit boards we are using on beta units appear to be working fine.

@EricNugent sounds good. @dani can we get a pn made for bearing mount with inserts? BoM 1X pp-gp0418 4x HD-MS0030

BoM changes-
Remove PP-IS0080 from bom
Add - PP-IS00--

New part number is PP-IS0114 and the bom has been added.

This has been updated in AS-PR0144 and pushed to the repo.

@west anything else needed before we move this to needs to be reviewed?

@DaniAO I just need to add the pn to the drawing and push to the branch
