Optimized A1 Start GCode?

[Malakae]

I know there’s an old post in regard to G-Code for the A1 mini, but I’ve yet to find anything for the A1, even with searching online. Was wondering if anyone knew of a place that has it, since I wanna optimize the startup of my printer.

Is it this one?

Optimized A1 mini Start G-code (Quick and Quiet version)

After some research and testing, I have made several small changes over the A1 mini default factory start g-code. It is faster, quiet and makes more sense at some sections. It works great for frequent, small printings. (Based on start g-code version 20240620, check your current version before using this) The changes are: 1, Disabled the “xy mech resonance check” on every print. Explain: It is not neccesary to check this for every small printing (The machine doesn’t do this check in the mid…

It was the first result on google.
