@logan When you are testing your jig can you also look at nozzle offsets and see if it can help get those more consistent? The offsets are usually accounted for pretty well when auto-calibrating, but more consistency could speed up calibration and make auto-calibrate work more often 1st time. I've seen offsets of ± 1 mm on x, ± .5 mm on y and ± 1 mm on z.
On the few that I've found, the height of the wiper pad has also been a variable. They are fairly inconsistent and that is what the blower shroud usually hits first when probing. I've pushed down the wiper pads as far as they'll go and trimmed the tops of them with flush cutters when necessary, and that usually fixes the issue unless the blower shroud is severely tipped. The combination of them definitely exacerbates the issue This could also be playing a role in the inconstant z-offset trends we've been noticing and issues with bed leveling. I'll keep an eye on the printers while probing today and post if I see anything that confirms my suspicions.

I've helped a lot of students with 3d printing their own files when I was at CSU so I know a lot of what to look out for.

Just finished printing this gcode on a Mini 2;
David just came by and told me to share the stl I was using. It's the stl in
I haven't changed it at all.
Changed support xy distance from .2 to 0.
Here's the file that I worked on a few weeks ago. David said they looked good and I haven't had a failed print yet from them.

I did some research over the weekend, and found a thingiverse page where someone described how they're making their own wiper pads. They're using .25 inch polyester felt, Mcmaster part# 88085K311, cutting them to length, then soaking both sides in Lulzjuice (abs dissolved in acetone). He said thiat this process was documented in the "Lulzbot whitepapers" if anyone knows what thoes are. I think this is exactly what we've been using. Links below;

We are also having the same issues with the TAZ's running Flexy filament. Would including the M420 lines fix those files, or would they need something extra because they are Flexy?

I can confirm that problem does not occur on other versions of the firmware. 220.127.116.11, 18.104.22.168, and 22.214.171.124 do not experience this bug. All instances of 126.96.36.199 in the cabinet have been downgraded to 188.8.131.52 until we can get new slices made.
