[Pausing on UM3 control panels causes nozzle to dig into part.]

1: I have 5.5.0

2: Could be any height, but mostly 20+.  Last time was 35 and 40, at 0.15mm layer height

3: I have gone through the manual calibration to even it out, but always Auto-level as it starts up.

4: single core prints, it embeds the printing nozzle.

5: left.

6: Nope, I don't swap.  It came with BB in the left, and AA in the right (used), and reading the manual, I saw that AA should be left, and BB right.   I have no issues printing (well, on general) like it currently is.

7: 5mm from the top of the lip to the bottom of the hot-plate.  Picture looks near even!

 

8: I have used Pause at Height, and it did the same thing.  Using Griffin M0 (firmware retract) method.

[Pausing on UM3 control panels causes nozzle to dig into part.]

I am NOT using Pause at Height modifier.

 

Every time I pause a print via the control panel, the Z stage moves up, causing the nozzle to imbed into the part for a second or two, before lowering, and moving the head off to Back Right.

I'm using Cura, but I assume this is a printer issue since I'm not using a script.

I don't have any issue after resuming, minus the hole/blob/etc where the nozzle took a drink.

 

What's going on?
