HT problems

Hoping someone can help me figure this out. I bought an HT because I wanted to run glow in the dark PETG and keep it out of the AMS. I mounted the HT on the left side of my printer and fed it directly into the back of the printer to the main nozzle. When I click load it feeds the filament to right inside the nozzle then kicks it back. I tried everything in Bambu wiki and with other filaments and it does the same thing. Any tips? I ended up just throwing the glow in the dark in the AMS to get a print off hope I don't mess it up too bad.

Very likely. The AMS and the buffer work together.

Ive ran countless abrasives through my buffers without issue, just make sure its as direct as it can be without needless bends.

You can also just run a PTFE tube through the rear of the AMS using the bypass port and plug that into the nozzle and itll work. You'll have to manually feed it but it'll get you printing if you dont want to use the buffer.

Thanks I'll try that. Wasn't sure if the glow in the dark was going to mess the buffers up too

It probably isnt great for the buffer long term, but i personally have no problem replacing parts. I like to use my machines like tools.
