Can't screw nozzles into heaterblock
This has suddenly started occurring, and I have no clue why. I change nozzles relatively frequently, from a 0.4 to a 0.25 and vice versa. I have never had an issue doing this in situ (using the nozzle changer tool) in the past. The last time I tried to change the nozzle, I felt a weird resistance and had to pull out the heaterblock entirely to screw the nozzle in. Now, I am completely unable to get the nozzle all the way in. I have attempted to clean the nozzle (which I am certain is not the issue, as all nozzles have this same issue), I have tried to clean the heaterblock, both while hot and cold, with a q-tip and a needle, and nothing has worked. The only thing that has worked whatsoever is screwing the nozzle in from the opposite end. However, I worry that having the wires coming out of the bottom of the extruder would cause multiple issues. What should I do? I have attached a picture of the farthest I can screw it in.

have you tried passing an M6 tap theough the heaterblock,
there may be particles of filament in the threads, blocking the passage of the nozzle!

RE: Can't screw nozzles into heaterblock
I had similar happening. The heater block is quite wiggly when you change in-situ, so it is relatively easy to cross thread.
Even in your image, you can see that it is not straight.
I had to remove the block, and carefully screw in the nozzle keeping it straight. Few shavings came off (sic), not it goes fine.
Now, I'm making sure, that when putting nozzle back, I press the heater block up, so all the holes are aligned properly.
