better double bearing holder
Closed, ResolvedPublic


The current design has the tension screw running between the bushings. If tightened the middle compresses but the ends get slightly bigger.
This new design places the tension screws right under the bushings for an even compression along the individual bushing

Parts needed to be added to the bom 1x M3x25 FHCS and 1x nyloc nut

@EricNugent have you had a chance to install this?

@west I dropped off 4 at your desk earlier today, I have not had a chance to install it yet.

@west installed on Quiver 7 and running a burnin, everything seems pretty good so far with the changes. Less rotation about the y axis anyway.

We will need to add another nut and bolt for the second hole to the bom.

Part looks good though.

@kent if you can provide the part numbers for the nut and bolt and which assembly this should be added to, I can get the BoM updated.

@DaniAO It should just be the existing nut and bolt. Only need to increase the quantity.


@EricNugent Okay what part number is this on?

@DaniAO This is the x-carriage double bearing holder sub-assembly or AS-PR0141.

@DaniAO Had a small mistake in the last one post and wanted to make sure the corrected was seen.

okay just the make sure I am understanding this right:

Need to add 1x HD-BT0206 and 1x HD-NT0001 to AS-PR0141. They are already on the BoM just need to up the QTY, correct?

Yes, there should be 2 of each on the BOM for AS-PR0141 double bearing holder.

Okay this has been updated in OCA and pushed to the branch. Ready for review.

As far as I can tell this ticket is only adding hardware qty to the BOM. The printed part design change was in another ticket already merged in. Those changes in the BOM were already added, and merged in, in another ticket that had an updated BOM export.
