Filament Not Detected
-
When trying to launch a print today, after a collision 36 hours into a 40+ hour print yesterday, my print head assembly (dual BondTech extruders) would move from Home to 0, 0, 0 after the print bed would drop about 25mm. A window would open to say No Filament Detected in Extruder. Changed extruders, did numerous extrusions of filament commands which worked fine. Tried the touchscreen, went through the Change Filament commands there and wifi Duet 3D. Homed before each launch. Selected filament from Filament File, etc, etc, etc. For three hours. Tried different previously printed files. Always the same response. Are there YAT commands that could be helpful? Thanks for any insights. Dead in the water at the moment. I have a Modix Big 60 V2>V3 upgrade.

We need to know what kind of filament monitor you have configured.
From the GCODE console, type M591 D0 and post the results here.
Hey, what the heck, why not post your entire config.g here also just to save time.

@alankilian Thank you. My tech will have to do that Friday. I will check out my filament sensor connections tomorrow by undoing and re doing. That's about my level. I just built and own the printer. And try to use it. Will hope to get more diagnostic skills as time goes on. Had four great prints 40-70 hours. Then this. Such is 3D printing.
Best,

Well, it ended up being Operator Error. When my tech set up the dual extruders, I did not understand filament needs to be in both filament sensors, even if there is only in one extruder which is printing. So I was only putting filament in the sensor going to the printing extruder and ignoring the other all together. So the guilty party meets me in the bathroom mirror every morning. Thanks to those that posted.

@modix2021 I'm glad you got it working.

One way to avoid that requirement for filament to be in the sensor even when not used is to add a command to enable and disable the sensor to the tool change files.
