Ran into a problem on my Ender 5 last evening while trying to do a print.
I have had this unit for about 1 year and have not had a major problem with it till yesterday. Like many Creality printers, it uses a “plastic” extruder. I run octoprint and noticed that the print didn’t seem to be doing as it should, so got up and investigated. Found a pile of filament all around the extruder head. Looking closer, realized the Bowden coupler along with its brass threaded insert had been pushed out of the plastic extruder frame!
Thought I would point this out as you may want to be proactive and order a replacement (metal) extruder head or even upgrade to something like a Bondtec or similar BEFORE the problem happens or at least have one in stock when it happens.
In my case, I am down till the new one can be shipped because I am like I am sure many of you are and there is no local source and had to order one.
Like a say, this is just a heads up for anybody that may have a plastic extruder body.
