Hello I seem to have come to a sore spot with my maker bot replicator 2, it recently had a leak on the top and bottom of the heater block and has locked the thermal tube in place and i have stripped the brass tip trying to get it off. I've replaced the thermal tube twice before and its still having issues printing (gumming up & leaking) but now i am unable to remove either one and I'm thinking the problem isn't the tube but the block itself. I've looked at getting a factory new heater assembly from maker-bot ( https://store.makerbot.com/x1-rep2-bar-mount-assembly )(i have tried to source the parts on this on my own but i cant find the actual block itself, the last one i bought wouldn't work as the heater core wouldn't fit), upgrading the printer to an all metal hot end ( Hack Your MakerBot with an E3D All-Metal Hot End | MatterHackers ), or just buying a new printer altogether but am unsure of what would be best since I'm fairly new to this and it looks like its about 150 whichever way i go. Any advice or tips would be greatly appreciated!
