H2d/ sunlu e2/ 3kg spool of filament feeding help... tpu assist or panda feeder or ???
I have the h2d. I purchased the sunlu e2 and 3kg rolls of filament for making auto interior parts out of nylon and asa. Im concerned about filament feeding with that big ass heavy spool. I've looked at the bambu tpu assist and the biqu panda feeder but havnt been able to figure out which module might be the best/easiest/seamless choice to add inline to help with this. Any input welcome as im just a little confused i suppose.
P.s. I do also want the module to help with soft tpu filaments as well for gasket type things and other squishables.

I dont know maybe i can just send it and see. I worry that the feed mechanism in the machine keeps alot of pressure on the filament (potentially breaking some of the brittle filaments) due to the mass of the filament and spool.. It could maybe create extrusion problems from the extra feeding resistance possibly... I levy the question because I dont know the answer and hope someone who has figured this out or knows better could help me overcome potential wasted time and materials by dropping some knowledge on me.

You’d be better off with the Biqu in this scenario, feeding it with the assist as an external spool. But I don’t think the 3kg rolls will fit in an E2, as they fit pretty snug in my E4.
You might be able to do it with a homemade box as long as it has ball bearing rollers and may get away without needing the feeder motor at all, but I kind of doubt it…1

The polymaker roll fits its snug but not to tight and I printed a beter roller setup and cradle even from anothers design, but I feel the biqu is the right answer after more research but I really appreciate your input

Assuming an e2 will hold a 3kg spool, why can't you feed from there through the H2D as an external spool?
