 Some things I have discovered about the Qidi XPlus-3, again:

* Its extruder idler is fixed in place. Yes, that means cold pulling is impossible on it.
* I've just encountered what looks like heat creep, repeatedly, from its hardened steel hotend, with two different filaments, neither of which are prone to it.
* Upon trying to unload filament, it jammed in the extruder, so now I have to take it apart.

Joy. I paid _premium_ for this experience!

 @5756e48c I'm _definitely_ going to report this, in detail, to Qidi's after-market support. For this much wasted time and filament, I expect _at least_ a hotend replacement. 
 @5756e48c But wait, there's more! Upon taking the extruder apart, I discovered its idler arm is cracked nearly in half.

... Qidi _better_ have some replacements for me double-fast, or I will have some _really_ mean things to say about them. 
 @20ffb98d @5756e48c Are you using the hardened steel hotend for non-abrasive filaments?
