I have problen with 3d printer after replace the filament runout sensor of the Dual Extrusion Module

HI,
I tried replace the filament runout sensor of the Dual Extrusion Module, but after it that module doesn’t use any more. My printer shows the error code

.

I don’t understand where is failed.

Did you proper seat the plug of the lifting motor?
Dont know what would happen if the t-nut is false placed…

Hi,
I solved that problem, but I have had other problem. Nozzle R is not loaded. How ever Nozzle is loaded manual.

Snapmaker Artisan

Problem: When printing with PA-6GF NYLON, a filament runout error occurred several times (erroneously).

When I want to load it again, it only heats the head to 210°c, so the filament doesn’t go through the nozzle.

After I press continue printing, it starts heating the nozzle to 295°C.

But until then, the filament will be filed away.

Workaround → Filament sensor switched OFF.

Solution → Firmware update?
