The file path is below. I've also logged this path in the product card for part PP-MP0282.
@kent @Jperry- do we have a drawing already for the new part? if so where is it stored?
I don't think so I made the adjustment and sent them off to toolheads so we should be good

I've released the units to Tom. Here are the numbers:

@adam They are capable of making it, since a good portion of the batch was made that way. I don't know if they will need to re-quote it or not. We will find out when we make our first RFQ with the new part number and drawing.

An additional note on changing the specifications for this part is that we need them to come with the M3x3 grub screw preinstalled. We are having issues with shipments not having bags of the grub screws accompanying them, and even when they are shipped with the screws, that bag of screws has to be kept track of without existing in inventory. Just having them be preinstalled would solve the problem.
Are we sure E3D can get this gear to us at the same or comparable cost to the aero pinion gear?
I created a change order under T8547

The new part PP-MP0282 is for the V3 version only
Just to clarify, of the units with holes closer to the edge, and the units with holes farther from the edge, which are going to be used for which assemblies?

I've created part PP-MP0282: E3D, V3 Aero Steel Pinion Gear w/ Set Screw. We will need to update AS-TH0055 BOM to have this part instead of the PP-MP0205.

To avoid this issue in the future, I recommend creating a new part number for the V3 pinion gear using our drawing, https://devel.lulzbot.com/TAZ/accessories/yellowfin/production_parts/machined_parts/pinion/22_tooth_gear_revc.pdf

I'm not entirely sure what has and hasn't been communicated yet. I have contact E3D about this and requested a drawing. Sam from E3D provided their drawing which was passed along to the appropriate parties at Aleph. I haven't heard anything after that.
Has the data that Kent created been communicated to E3D?

@kent I believe it is Baldwin's drawing so that the interference between the tooth profile of the spur gear and the hole for the set screw in the pinion gear is minimal. this will help prevent broken spur gear teeth. Ideally there would be no interference between the hole and the spur gear teeth.
This is e3d's drawing:

The current plan with MER is to release 20 units to have built out and tested for issues.

@AOJAS you are using an aero gear, those are 4mm thick. The yellowfin gear is 6mm thick

This is resolved with the washer added in step 11 here: https://ohai.lulzbot.com/project/dual-extruder-v3/hot-end-tool-head-assembly/
This should be resolved with the addition of a washer in the idler lever assembly (step 11 here: https://ohai.lulzbot.com/project/dual-extruder-v3/hot-end-tool-head-assembly/)

@kent where is this washer going? on the m3 screw between the idler and the plastic part?
Dec 3 2018
Steps 10 and 11 should be updated here to add a washer, I think this will solve this issue. https://ohai.lulzbot.com/project/dual-extruder-v3/hot-end-tool-head-assembly/

This issue has seen a sharp increase in a small time span so I would like to call attention to it.
Nov 13 2018
We received the parts made to the new drawing today, and I tested them with some of the gears that had holes on the larger side and they work.

@lansky THanks for the follow up, closing this one out.
@karrad At this point I think we can stop tracking these.

@lansky Do you feel we still need to be tracking these, or has the SB addressed the issues? (I am guessing the few we have rad reported were do to material defects.)
With PLA and other materials susceptible to heat creep, an enclosure is not recommended.

RMA12448 had this reported issue.
RMA 12379 had the same issue. The left side (E@) knurled hobb was spinning in the large gear.

@anolen Re-reading this ticket, it looks to be resolved with no print drop issues. Going to close out, please re-open if you think it is necessary

Had this issue on RMA12343 causing a failure to extrude on the right nozzle.
