Yes, I have had about 6 prints with it so far, it ran great until now

You could try to re-flash the firmware just like you did last time...if successful, it rules out communication problems with the board itself.  Did you use Arduino to re-flash?

Heater cartridge wires are good.

No luck, replaced the damaged thermistor, and the problem persists.

And the wires to the heater cartridge?

- USB cable connections
- Swap cable if you have a spare
- If the Com port somehow got switched in RH

I presume you were clearing a clog?  What if it wasn't clogged but had a broken or intermittent connection to your thermistor or heat cartridge?  That may cause your connection issues to your PC.  I would guess that during cleaning you moved the wires just enough to break an already weak wire/connection.  All you can do is look around and see if you can find anything.

It very well could be the thermistor wire. It had broken once and I repaired it, and ordered a new one for when that repair inevitably failed, but could that cause the communication issue?
I'll repair that when I get home and report back!

I assume you where using a brass brush like most of us do, yet there is a little catch nobody seems to get. The brush can be used and should be used when the nozzle is hot, but NOT while power is applied as in heating.

You need to first confirm the power supply is still god and was not affected. Measure the output on all outputs and confirm they are the correct value. If they are good then move to your mainboard on the printer. See if it has a fuse, and see if that fuse is open. Actually I would check the fuse first since that is it's purpose.

I recently installed an E3D v6 and have had about 6 prints with it so far.
Any tips?
