Mini 2 gets stuck in a level X axis then wipe nozzle loop
Open, Needs TriagePublic

Description

I have notice this error on my Mini 2 with firmware 1.1.8.59, it also occured in 1.1.8.51

Steps to produce it

  • Start a print
  • Fail autolevel routine
  • While it is going to level X axis cancel the print
  • Now it will loop with leveling X axis and wiping nozzle until power is turned off{F1962296}

@keebie81: We just tested this in house and the printer will stop leveling after three retries. The way "Abort Print" works is that it stops subsequent commands from executing, but the current command will be allowed to finish. In this case, the command is "G29" which consists of the entire probe/re-level/retry cycle repeated three times.

Clearly it would be better to have the printer stop immediately, but this would actually be rather challenging to do, due to the way Marlin is written internally.

Did the function of the g29 command change? I have a printer from production that seems to get trapped in a failed probe loop with out even attempting to probe the first corner. As soon as it levels the x-axis it goes to rewipe.

Never mind, I may have been using the wrong command.

@keebie81 we have had a few firmware updates since you last posted. Are you still noticing this as a problem or can we count this one as resolved?

thanks!
