Extruder body interference w/ blower shroud
Closed, ResolvedPublic

Description

In the pictures below it can be seen that the E1 extruder mount sits lower than the first.



The following picture highlights where it is interfering

We attempted to change the position that E1 rests as suggested by @west, by loosening the fastener securing the actuator to the actuator mount, pushing the actuator up, and tightening the fastener back down. This did not alleviate the issue.
I had not previously seen the extruder down that far. @MikeR said another unit he had was opposite; E2 resting farther down than E1.
I also noticed that the old rev actuator connector was used with button head fasteners, as a result the button head fasteners are about half way seated inside of the pocket meant for socket head fasteners. I couldn't see an play between the actuator and the actuator connector as a result of this however.
This was on QB12, we tried another fan shroud without any luck.
I asked @paulette to reassemble the tool head and continue trying to calibrate the machine, noting down any issues she has along the way that may be related such as interference with wiper mounts or the Y cable cover.

Also see 2nd photo on T5879; the interference between the cable guide and the fan shroud can be seen there at the curved portion towards the front of the shroud on the left. This has been a common point of interference through betas. Sometimes it can be alleviated by moving things around, others not.

Changes made in T5995 seem to fix the issue

T4736 will need to be updated on approval and the bom will need to be updated to add this part (pn pending) and 2x HD-BT0042

@DaniAO will you please add 2x HD-BT0042 to AS-TH0073?

@EricNugent please push a gcode for this part.

Gcode is pushed and production folders are updated.

Bom has been updated and push branch
