Shoot. It's weird. We were able to run a clean cycle of print core, the one that we unstuck, in the #1 spot, which worked fine, but when we unloaded and loaded filament, there was no extrusion. We swapped the AA 0.4mm for the other AA 0.4mm print core into the #1 spot and tried to unload and load and still did not get any extrusion.
We moved the previously clogged print core from the #1 spot to the #2 spot and it worked fine, so it's not the actual print core that is faulty, but the #1 spot.
What do you suppose is preventing the #1 spot from being able to work properly?
Thank You. -Charlie
