RE: "ERR: MINTEMP", not loose wires, possibly the EINSY(?) board?
Is there any way I could use the unused Therm1 socket instead?

I think there is by making your own firmware I remember while ago someone wanted to do same thing if you post on forum someone might be able to guide you with more experience might be worth ago before buying new board
Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models

Ahh, thanks 🙂
I was kind of hoping for something less involved - maybe a GCODE command (or similar) 😉

Unfortunately I don't believe there is one you can always post thread but probably get response of code firmware

Hi, I have the same problem.
I was hoping to reassign T0 to T3 in the firmware or replace the blown component.
Does anybody know how to edit the firmware or have a good link to share?
Does anybody know what component this is and its value, or have a link to share?
Thanks in advance!

Update:
I fixed it!
My hands are a bit shaky, so this is the worst soldering job I have ever done. I is also the smallest soldering job I have ever done.
I removed the surface mount component from the unused thermistor port and placed it on T0. One of the traces from where the original part blew were destroyed, but I managed to determine that it connects directly to the left pin on T0. As you can see, it is anything but professional, but it works now!

excellent botch! lol...
was it aa brass brush that shorted the heater to the thermistor cirtcuit?
I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

For those that shorted the hotend thermistor while cleaning with a wire brush, you can use the other unused thermistor connector by reassigning the pins and rebuilding the firmware.
Specifically, you must swap the TEMP_1 and TEMP_0 pins just as I did here: https://github.com/esauvisky/Prusa-Tweaked-Firmware/commit/15b23e5f279d0ccc3bbfe434a7621e330bca7a33
This happened with my MK3S+ a couple of years ago, and it had been working perfectly fine until today when it happened again. 🤦
Unfortunately, there aren't any other unused thermistor connectors in the board, so now I have no alternative other than troubleshooting the Einsy PCB and hoping I can replace whatever blew up. 😭 From what I read, that component is a fuse which explains why @electrosteele botch worked.
Be very careful when cleaning the hotend with wire brushes while the printer is turned on, because this can happen even when the hotend is idle/not heating. I definitely won't do it again without turning off the printer first, lol.
