Do you hate to wait?
Just use my custom fast start g-code for the Bambulab A2L.

It reduces nozzle cleaning/wipe and does not wait 3 minutes for bed heat stabilization.

Please manually check whether the nozzle is dirty before printing.

The printer starts after around 2:10 minutes (incl. bed leveling) with the job.

I have been using this start G-code for three weeks and have tested it extensively without any issues.
But keep in mind: non official g-code - use this at your own risk.

How to use:
Go to printer settings - open machine g-code tab - select all from machine start g-code, delete it and replace it with the new code :
