It doesn't (yet...). I will need to print a new filament drive housing with appropriate clearance so the sleeve/bearing can rotate freely. I plan on using black ePC, but I want to finish at least a few sides of my enclosure to help maintain the high temperatures required. No one has responded to my ...

I machined an aluminum grooved sleeve using the drawing I posted earlier. Sleeved Bearing in Drive.jpg It pressed onto the bearing very nicely, but when I installed it in my worn out factory housing, it wouldn't turn. I recently converted the factory SLT into a Fusion 360 solid model, and when I che...

This WAS a thread about black ePC, but it's gotten hijacked. If you want a suggestion about dealing with PETG, I just posted a reply in a thread that is actually about PETG.

Use hairspray (Garnier Fructis #5) on the glass side of your build plate. PETG sticks just fine, and pops right off when you are done. If you flip the build plate, you may have to re-level. The thickness isn't uniform down to the level required for fussy prints. In my case, I used a micrometer and f...

I want to use this to print a couple new filament drives. I found an old ePC factory file, but it predates the black version, and is presumably for the clear stuff. I know Zemlin had issues with the black early on, but I'm hoping eSun has improved the stuff and/or folks have figured out the magic se...

I've attached a drawing of what I have in mind. The press fit over the bearing is tricky. If it's too tight, you may snap the sleeve. If it's too loose, it may expand enough when hot to begin slipping. I made a guess as to what would work, but I can't easily measure stuff that fine anyway, so it's m...

I've had some success removing baked on crud from a nozzle used for a mix of PETG & PLA. I soaked it in "Zar Paint and Varnish Remover", which is about 95% methylene chloride. It's nasty stuff, and you should use gloves and good ventilation. There's still a bit of carbon on the outside, but the bore...

I ran into this a couple months back. I just gave up on previewing anything with more than one attachment... I didn't know if it was me or the forum software. I guess now we know.

A printed sleeve is going to be very difficult to make precise enough to get a good press fit. You also don't want to introduce ANY diameter variations that will make it feed unevenly. It might work OK for soft filament, but if you want it to work with more rigid material, I suspect it may wear quic...

I have a dead housing with the factory bearing in it. It looks like there is about 3/4 of a mm clearance of each side (~ 17.5 mm ID). So, you could make the OD of the sleeve 17 mm, and the bottom of the groove 16 mm (1/2 mm deep). You might have to shave down the OD a tiny bit from that to fit in an...
