Fixed it, machine is now working with backup printcore. I do not have the luxury of sending my machine up to be fixed when the problem is just the printcore specially with my fundraising for ZSL in full swing.
The filament oozed up and into there and hardened like a rock...Since Printcore is already non-responsive (tried the atomic method shown in the support pages first), I had to use my heat gun to slowly melt and pull the filament off bit by painful little bit. Last bit was that part that's blocking the printcore into the printhead. I tried prying the filament off gently, but instead, the bottom bit of the printcore came off. To not cause damage, I had to open up the print head to reach it, put it back together (less a screw since one escaped) 😞 I need a replacement printcore and short bolt pretty please (for the printhead) 😛
