Reprinting Filament Drive. What material should I use?

Post by bratan » Wed Feb 28, 2018 2:31 pm

I've been struggling with my M2 Rev E printing Ninjaflex. It was just one printer, other one prints it just fine. I think i figured out the issue. 3D printed filament drive has elongated hole where filament goes, almost like two holes joined together. I don't know if my filament wore that out (I've mostly been printing flexibles) or it came defective, but in either case Ninjaflex sometimes slips into other opening and it results it to slip of the extruder wheel. Chances are 50/50, it could print just fine, and then next print it's off the wheel.
Long story short I just want to reprint "Single FIlament Drive r3". Anyone knows what is original part printed from, PLA, ABS, PETG? I swear it looks like PLA :)

Also if you can share any tips on printing it (i.e. support, infill) I'd really appreciate it! :)

The stock ones are ABS but I don't know what infill they are. (I usually print my stuff at 80%) Some people print them out of PETG so they are stiffer and others print them out of ePC so they have better heat resistance. No matter what you print them out of they will eventually wear out. The holes do become oblong after time and I find the bottom part that forms the hinge becomes less ridged and even cranking down the tension screw all the way doesn't seem get a good enough grip after time. (I actually use a modified hinged version of the drive now and it's been going strong for 2 years now) What ever you print them out of always print a back up because you will eventually need it. After printing them you will probably have to ream the feed holes out a bit too, this allow the filament to feed through the drive smoothly.

Thanks! :)
Just printed mine out of white PETG, drilled out hole with 2 mm drill bit and it seems to work great so far. Ninjaflex no longer jamming so I'm happy.
I'm ordering some ePC so will probably reprint it later. Thanks for the link to hinged version, I'll check it out!

I printed mine in ePC, the filament I love to hate. Amazing stuff that has a 100% success rate in clogging my nozzle on the transition back to PLA. :D
I'm finally back to where I started two days ago!

A thread with some stuff in it I update every once in a while. viewtopic.php?f=8&t=9

I was all set to print up some spare drives & play with a few design mods, and I've got a brand new spool of black ePC to print with. However, Zemlin reports that he hasn't been able to get the black ePC to behave nearly as well as the natural/clear ePC. I asked about using PETG in that thread, and he thinks it's not very slippery, and that might cause problems.

It looks like several people are using PETG for their drives, and I was wondering if they've seen any issues with them and how well they hold up. I have a spool of black PETG on the machine right now, so it's would b easy to spit out a couple spares. The alternative is to blow another $28 bucks on a spool of natural/clear ePC.

Thanks!
