AMS Smooth PTFE (update December 23)

This is another solution to the AMS filament mouth abrasion and a system to smooth the transfer from the spool to the AMS. I tried the clip-on V2 button thing, but it's unstable. I noticed some did add a PTFE, and I thought that was a stroke of genius. Also, some have an excellent bracket design that gives the filament a shallower angle of attack when getting in the AMS. Well, I did design that one that gets all the good stuff and is stable. I have been using in (4) AMS for over 2 months, and I have no issue, no sign of premature abrasion. It did resolve the spool jerking and jumping.

I use a (PTFE) Teflon tube 2 bore x 4 OD x 50mm and print it in ABS and PETg. It is somewhat tight at the first insertion on the AMS but stable. It is tight with a new spool but works well. I thought the PTFE could be shutter, but it works well. Why fixing-it? It int broken… Yet.

All right, after 30 days of being out there and doing very well, I decided to bring it to another level,

Voici, the soon-to-be-famous the v4,0n.

Get ready for the blah blah blah about it;

Updates: It has the best spool clearance, is taller, has a greater filament radius, has a slimmer nose, does have space for a large desiccant box, allows up to 18mm button, Slimer and more clearances for the PCB.

It's close to the V3.0 but doesn't have the -2.5-degree backward Improved spool space.

I tested it with ABS, and it works as expected, but I recommend using BBL Transparent PETg.

Do Not use PLA. Or only if it's a really good quality, tough one, and you went to the post-process of heat treatment. Put 6 walls, 6 tops and bottoms layers. I think it's asking for trouble using PLA. I should try PLA-CF… That could be fun, Right?

Enjoy, and have a happy new year.
