I Fixed My Centauri Carbon Clog in 10 Minutes Here's How

@cymplecy 😆 I literally used this video yesterday to troubleshoot a clog I had yesterday. I briefly lost one of the bearings in the process.
@3DPrintingDad I lost a bearing as well! I was just about to lookup how to order another filament feeder when I spotted that it was lying inside the case :) #Phew
@3DPrintingDad As a matter of interest - how do I get the filament guide tube out - do you just pull it out?
@cymplecy On the hot end? There should be a little ring around the tube you can press on. When you have it depressed, the tube should be able to be released. Let me know if you run into problems!
@3DPrintingDad Never occurred to me to press the ring down :)
@cymplecy It's not obvious. The main reason I know is that my first printer kit (plywood frame!) used an indirect bowden extruder, so the bowden tube was absolutely necessary for the printer to work. The "push to connect" fittings would eventually chew into the PTFE tube, so between clogs and tube maintenance, I got quite familiar with them. 😂
@cymplecy Fun fact: the cheap push to connect fittings use a ring of teeth that can easily break. I had more than one occasion with that first printer where I had to do repeated cold pulls to get metal teeth out of the nozzle. To date, I've never lost a nozzle to a clog. I'm stubborn. 🤣
