Summary

Work in progress and untested as of yet.

I want to use a Volcano hotend on my MK2S, but to my surprise, no one seems to have made a mod for this yet. Only for the MK2 (different pinda probe). So I tried my self.

The MK2 volcano extruder cover and fan nozzle are made by dshamiel, I changed nothing, I just uploaded them here for your convenience. The extruder body, which holds the PINDA probe, is a remix of the MK2S original, I basically just "stretched" the pinda holder so it gets lower. Its not ideal, as the screws that clamp the probe are probably further apart than the probe is long, and I couldnt see a way easily extend the grooving properly, but I think it will be good enough until someone makes something better.

update 1: I printed the parts and it seems to fit, although I have not mounted it yet. Unfortunately, you will need to modify the firmware to accommodate a taller hotend, or you will run in to problems doing XYZ calibration:

Basically you have to reduce the Z max height in firmware by ~8mm.
