[BFW-6063] [BUG] Bed Leveling RETRY option can damage print bed surface. #4222

Printer model

Mini

Firmware version

6.2.0-alpha1, 6.1.2, 6.0.4

Upgrades and modifications

None

Printing from...

Octoprint 1.10.2

Describe the bug

My mini has begun failing bed leveling about 10% of the time. (Still diagnosing the problem. The knowledge base article only mentions other models).

After a failed leveling attempt there are two on-screen options. RETRY and CANCEL. If I choose the RETRY option the printer DOES NOT retry bed leveling, but instead begins the print, but with zero (or slightly less) z-offset which leaves the nozzle scraping along the bed.

With firmware 6.2.0-alpha1, the message notifying the user of the failure also contains a QR code. This contains the url of a page touting the Mk4s. (?!?)

How to reproduce

No response

Expected behavior

The printer should make another attempt to level the bed.

If using 6.2.0-alpha1 firmware the QR code should contain the url of a Knowledge Base article providing help diagnosing and fixing the failed bed leveling.
