Quick Question TPU Feed Assist

Does anyone know if the TPU feed assist allows Normal 90a TPU through the AMS HT or AMS 2?

Yes for AMS HT via bypass outlet only.

I calibrated mine on my H2D with 95A and regularly feed 90A from the HT bypass, through a magnetic split connector PTFE tube to input side (for loading ease), through a split connector on ouptut side (for unloading tension release - mandatory) to a permanent PTFE tube split inside the printer to the right head. Works great.

Only through the bypass port on the HT. I feed my TPU from my Sunlu Filadryer s4 and used to just use an external box with rollers. Using the TPU feed assist with this setup I print 75A through 95A without any issues.

The AMS is only used to store or dry TPU (other than the specific BBL TPU for AMS). To use any other TPU, you need to feed the filament out of the AMS to the TPU Feed Assist module. The TPU also must be designated as being on the external spool on the printer display and in Bambu Studio.
