tl;dr: What's the best way to change filament in this machine?
Total 3d printing newbie here. Got my X-one on Monday and was up and running in no time. Today, I wanted to change the filament from the one that came with the printer to a red one I had bought at the same time. There don't appear to be instructions in the "manual" (the short pdf that came on the SD card), so I Googled and saw there seemed to be 2 ways: reverse and replace, or push new after old.
I tried to push the new after old and just ended up with a clogged nozzle (at least there's a good YouTube video out there on how to fix that). That was a pain to fix and I don't want to have to do it every time I change filament. So I'm guessing I really should reverse out the old and replace it with new.
Just so I don't mess it up again, I wanted to make sure I know the procedure on the X-one. Here's what I think I do - can someone correct my errors?
- Preheat the extruder to the high end of tolerance for the material (220 for the pla that came with the machine)
- Release the sheath covering the filament leading to the print head
- Reverse the filament a few times (using the up arrow on the screen that shows up when you navigate to tools-->filament) until you can pull out the filament from above the machine (where it first entered)
- Load new filament just like on a new machine.
Is that right? Are there any other tricks to doing this easily?
ps replacement filament is Hatchbox PLA 1.75. My original changeover issue wasn't related to bad filament, just bad technique. :)
I got ahold of some ABS filament with the smaller hub size. 33mm instead of 55mm. Doesn't fit on the stock Qidi holder. My solution may be old hat to some of you, but a 10mm x 80mm bolt makes a great, universal spool holder with a lower profile than Qidi's.
