Filament ooze messes up bed leveling

I’ve found that sometimes I have to cancel my print and restart it so the mini will wipe the nozzle twice. I notice that even after wiping, some filament will creep out and it causes the nozzle to hit the washers harder instead of just lightly touch them. This is solved by restarting the print. Any ideas for how to fix this? Maybe changing my start g code could alleviate this issue.

What I did try:
I did try changing my retraction on the start g code. I have it retract before wiping and then retract again before leveling. The issue is that it never reads my command to retract before leveling. I’m not sure why.

Thanks,
Max

If you are using the start gcode provided by Lulzbot the filament should be retracting 15mm before wiping and measurement.

What temperature is your nozzle while wiping and tapping corners? For PLA it should be in the 140 - 150 range depending on the filament.

The start gcode should look something like this example from the Mini 2.
