Ground wire coming out of connector on the y-axis motor.
Open, Needs TriagePublic

Description

I've accidentally had the ground wire that connects to the y-axis motor come out of the crimp on the connector. I currently do not have any pictures, but am making this ticket so that we can track the problem.

T7984 is a ticket about this problem with the Redgum.

Full conversation in T7984, but to summarize:
The proposed solution is to:

  1. Lengthen ground wire
  2. Use redgum Y Motor Mount (same PP-IS part and leave un-used inserts, NBD)
  3. zip tie ground through strain relief on Y-Motor Mount

This solution also eliminates a unique part between Quiver/Redgum.

Alternative would be to pursue different ring terminals that would hold the insulation and be crimped properly. This would require more time and considerable expense in vetting a different ring terminal and purchasing the tooling to apply it.

@DaniAO should we make two change orders? One for the printed part and one for the drawing or can we roll both into one change order

Being that if effects one assembly, I think it would be okay to do this all in one change order.

I've got an RMA Taz Pro that I'm working on right now, and it came in with the y motor ground wire out of the connector. Is there any updated part or harness that I can use to fix this?

Not until the CO is complete, going to have to return it to current stock form for the time being I would think

@DaniAO What is the status on this MO? This is a common problem that calibration will see when they get the Taz Pros. From what I have been able to see the crimp is being broken when the printer is being moved around due to there not being enough space between the bottom of the motor and the surface that it sits on.

It is in the testing review phase
