afinia h400 motor stepping

by jfkdhfhd

hey guys, I have an Afinia h400, and the motor seems to be stepping, and the filament stops extruding properly. I have cleaned out the motor and tried a bunch of different things, and the only thing that seems to work is when I guide the filament by hand and relieve tension, but I can't do that for every print. Got any ideas?

Afinia Build surface

by ccooksey

Hi! I haven't been using my Afinia H480 for very long, but starting to branch out, try new techniques, etc. I've only really used the perfboards that come with it for a build surface. I've read about different things, Borosilicate glass, using Kapton Tape on the platform without the perf board, using the Blue Elmers stick glue, etc.

I recently started having some lift up on the edges of prints before they would finish, and obviously some ended in disaster. I cleaned the perfboards with acetone, cleaned the nozzle, recalibrated everything and made the bed level and set the nozzle height and everything seems to be doing fine again. I do preheat the build surface to 105, I don't always wait until 10 minutes after it's made it to 105 however (read that was a good practice somewhere).

So, what good build surface tips are there for the Afinia 3D Printers? What's the easiest to deal with, which don't warp your prints, etc. etc.

What is this for?

by Ohio3wheels

I've had my H479 for just about a year and the other day I decided to take the "head" apart and clean it and also just to see what's what. There is, for lack of a better word, a damper that in one position defects the fan blast on to the build plate and in the other on to the heat sink. There is no mention I can find in the instructions as to what this is used for. Any ideas?
