Filament flow error by dual print
Quote from Plamen Stoyanov on 2025-05-06, 19:45Hi all,
I'm trying to print a cube in dual print mode on a Craftbot 3, but both extruders are getting constantly filament flow error after the extruder switch. The filament monitoring system is trying to resolve the issue, sometimes successfully, sometimes not. The result is that without interaction it managed to print no more than 5-6 layers. Filament is PLA, slicing profiles I used are Default and Easy, pretty much all settings are left as default, print temp is 210C, layer thickness is 0.2-0.25mm. It is with Ooze option enabled.
What I think may be the problem, is that there is a heat creep in the extruder while in stand-by position and on print resume with the corresponding head it just gets jammed and the idler gear starts to grind against the filament and it gets stuck. I think a slow priming of the extruder before it gets moved over the bed will resolve this issue, but I can't find a option in the settings for this. The other option is custom G-code, but I have no idea where to put it, to get executed on every swap of the heads.
Any ideas/suggestions how this issue could be resolved are highly appreciated!
Cheers!

You can insert custom G-code at tool change to ensure the incoming extruder is properly primed.

Heat Creep in Inactive Extruder: The inactive nozzle heats up while idle due to residual temperature and lack of filament movement. PLA is especially prone to softening too high in the hotend, leading to jams.

Quote from Emily Hunder on 2025-06-20, 04:39Experiencing filament flow issues with my Craftbot 3 during dual printing. Seems like a Snow Rider game level where obstacles keep appearing! The printer halts after just a few layers because of constant filament monitoring errors post-extruder switch. Using default PLA settings, 210C temperature, and a 0.2mm layer height. Ooze option is enabled, but the error persists. Any advice on troubleshooting would be greatly appreciated.

Sounds like a solid workaround. Good luck!
