[Feature Request] Turn off automatic filament unload after a print and/or a prototype mode

[BambuLabDiscord]

When I am working on a prototype and doing a lot of 5-10 min prints, I would like the option to turn off the filament unload after a print. I'm doing a quick print to check the dimensions and need to do another one right after. Unloading the filament wastes time and filament. I have been using the manual side loading to solve this but this is not an optimal solution. Having a prototyping mode would be great to stop unloading the filament and maybe also remove all of the pre-print stuff that takes 5-6 minutes before the print begins. I'm not talking about the bed leveling or flow tests, I have those turned off for these quick prints, I'm talking about all of the other stuff it does before a print. Just a thought. Thanks!

Yo! As a temporary fix i suggest using external spool, it does not get unloaded between prints (obviously)

A way better temporary fix than ditching the AMS is making a profile for it, here's how:

1. In Prepare or Preview tab of BambuStudio, change settings for printer by clicking the edit icon to the right of eg. “Bambu Lab (…) 0.4 nozzle”.
2. Go to tab “Machine G-code”, and then section “Machine end G-code”.
3. Find these two lines of G-code (they're located soon after the second blank line):

   ; pull back filament to AMS
   M620 S255

   Remove those two lines and then save the setting with a new name eg. “Bambu Lab (…) 0.4 nozzle - nounload”. This will be a "User preset". The "System preset" remain unchanged so whenever you actually want it to unload, pick the System Preset before printing.

Still, I too would like to have this option among the "Print Options" in the device tab, among eg. "Enable detection of build plate position". Actually I can't really think of any situation I'd actually want it to unload though?

Absolutely amazing. Thanks for this, already used it as a workaround. Hope Bambu can implement just a tick box when sending a print.

Adding the option with the other "Level Bed", "Enable AMS",... to not unload would be a good implementation.

I, too, would benefit from this significantly.

The X1C speed is amazing, and really lends itself to quick prototyping -- having to reset the AMS every print wastes a ton of time.
