Optimized startup GCode for Bambu Lab P series. Keeps all the original startup actions but changes the order in which they happen, and proceed with the startup instead of waiting for the bed to heat up. It's usually almost always ready to print by the time it's finished, unless you're printing with a bed temp above 60C it might pause before proceeding.
This changes the purge line to be similiar to the KAMP purge line.
Not tested on units with AMS.
Use at your own risk!
