Upgrading my Mk2S to a hybrid Mk2.5 R3 extruder
I've recently upgraded my Mk2 to a Mk2S and remixed the extruder to include a PINDA V2, the Noctua fan and the R3 improvements. Details at https://www.thingiverse.com/thing:3062641 . The printer works fine after the upgrade. I had nozzle issues due to an incorrectly mounted PTFE tube (collet was not pulled out) which are resolved by now.
The PINDA V2 requires a temperature calibration backport from Mk2.5 3.3.1 into Mk2 3.1.0 which is in progress at https://github.com/baloan/Prusa-Firmware . Has anyone done the firmware backport already? Comments welcome.

Very interesting. My preferred way will be to upgrade the bed and not the extruder. You did it other way around, any reason for that? Why not complete MK2.5 upgrade?

The only thing I'm really missing is the temperature compensated PINDA probe. I neither need the spring steel heatbed nor the Bondtech extruders. I'd rather invest the money in upgrading to Mk3 24V electronics (Einsy board, 24V heatbed etc).
I never had troubles with the Mk2 heatbed (once I learned acetone restores stickiness)...

you say that now - you probably have never had to replace a damaged PEI sheet off a Mk42 heatbed. after that messy, gooey, experience - the spring steel sheets are a godsend, i tell ya.
just finished my first petg prints (spare extruder parts, of course 😎 ) off a new textured sheet... *and* they just pop off... no neurosurgery maneuver needed prying parts off with a knife/spatula - didn't even need to use windex/gluestick, so no cleanup required...
- what - a - blimmin -pleasure -
all 3d printers should come with them standard 😀
sure i'm happy. but not totally happy:
*the long wait for the shipment was ridiculous - and to think there are folks who ordered before me that are still waiting!?
*a part was missing! (the part fan nozzle)! luckily: 1.it was a printable abs part - 2. i actually had orange abs filament on hand
*part cooling fan seem to have developed an annoying whine (pwm noise?) firmware issue?
