Just bought P1S Combo, and was wondering that stupid feature. The starting procedure lasts way too long, several minutes and there is no need to waste filament with purging. I nearly always use same filament and I really hope that @BambuLab would give us the option tho choose not to purge and shorten the starting sequence!
+1 - im rapid proto-typing a design (~7min print time).
writing this while the printer is again doing its 6min start-up and purges of the same filament it will use after i’ve checked out the printed part and made adjustments.
it would be great to keep the printer in a “will continue with a small part again in a few short monemnts” state.
While waiting for the feature, one can use the external spool holder for prototyping. The filament will stay loaded after the printing is done. The filament will be out in the open air but for prototyping that uses PLA it should be ok.
@DWdesigns yeah, that doesn’t work though. The printer still purges before starting a new print. This is ridiculous.
I found a Fast Start G-code that really does work on the A1. It only does one purge and is very fast to start the print. It’s a life changer!
Hi, would you mind posting the GCODE you found for the A1?
(New user, trying to avoid waking my kids when I start a print before bed).
I know thats a slightly different problem, but why is there no conflict warning when the purge line is overlapping with a part of the print object?
I just had a slight overlap that kinda ruined the optics of a otherwise fine print ;-(
It seems this “issue” tends to lose momentum after a few posts on GitHub or in the forums, once users discover they can edit the G-code. I don’t think this workaround should be considered a real fix, though - it’s kind of the opposite of why people buy a Bambu printer in the first place.
It’s mainly annoying in two situations:
-
when you’re rapidly prototyping small prints, where the preparation time can exceed the actual print time
-
when you’re using an external spool holder and both you (and likely the printer) know that the filament hasn’t been changed
As a layperson, it feels like this could be solved with a simple checkbox in the filament settings. But since this hasn’t been implemented for years, I assume there’s a more complex technical limitation behind it than just disabling the purge at the start.
Would anyone mind shedding some light on this? 
Amazing that there is still no movement on this. Bambu needs to change the advertised build volume if they won’t give us an option to remove the purge line, or at least move it somewhere else. Absolutely stupid that this is even a debate and pretty silly that there are no official method to disable the purge line.
