E3D V6 Hot End - 1.75mm

Pretty good upgrade

I did well with the upgrade on a Prusa i3 Mk3+, except for the new type thermistor. I couldn't get a new firmware compiled without a multitude of issues. The guide is outdated, so the instructions are no longer correct regarding changes to configuration.h or configuratioin.adv and with my attempts at hacking it, resulted in compile errors. So, I reverted back to a Prusa thermistor. Also, the fan is pretty cheap. Mine broke a support off when installing it when I pressed on the center of the fan to push it in place. I can say all this in confidence as I have over 30 years experience, including a career with computers and manufacturing electronics. Other then that the updates are worth the while for me. I also have installed bondtech gears and would recommend that update as well.
