Official H2D Prototyping mode

Bambu Lab H2 Series

Could Bambu Lab add an official prototyping mode for the printer?

The idea would be that, once the machine is powered on, it performs its normal startup routine one time per power cycle. After that, when a print file is sent, the printer could begin printing immediately without the usual 6.5 minute wait, (6.5 minutes it takes on my H2D with Flow dynamic calibration, Auto bed leveling and nozzle offset calibration turned off to get the printer printing)

After the first print finishes, the printer could keep the filament loaded and remain ready for the next print without repeating the full startup process, unless the machine is power cycled. For safety, it could still do something minimal before each new print, such as a single bed touch and one endpoint move.

In a typical workflow, I would power on the printer and then prepare the print file. During that window, the printer could already complete its one-time startup checks, so that when I actually send the file, it can start printing right away. And every print after that is even faster because it does not have to re-load the filament.

How is this different from just setting flow dynamics and bed leveling to “off”?

As I wrote, 6.5 minutes it takes with everything turned “off”

I would like to see this as well. It wastes so much purge filament and time when printing many prototypes one after the other.

This is an absolutely epic idea. @SupportAssistant

In the meantime, you can use the external spool holder when prototyping. It doesnt unload the filament when the printing is done.

Thanks, I know that, but rather than using the rolls in the AMS, I want Bambu Lab to implement this properly so people no longer have to rely on workarounds. Also, this only solves the unloading issue, not the long startup routine that gets repeated over and over again. No user should have to tamper with the machine G-code either.
