Dual Extruder runout switch adjustment/repair?

Snapmaker 2.0

I’m loving all of the enhancements for my first-generation 2.0 A350: the 10w laser, the dual extruder, and the quick-change kit. I also have installed a glass bed with metallic tape and am getting perfect first layers and auto-calibration, it’s amazing.

My most recent big job (88-hour print time) is running into problems with false filament runout conditions. For the moment I’ve swapped so I’m printing primarily with the right extruder and that’s helping me get through it, but that just reinforces my notion that the runout switch in my left extruder is malfunctioning.

I’ve seen the videos for adjustment/replacement of the runout microswitch in the single extruder. Is there an equivalent guide for the dual extruder? I’m not squeamish about opening it up.

It seems that there is a systematic problem with the first DX version.

In the meantime, you can override the runout sensor with a “M412 S0” command in your G-code so you can at least print.
