Mk8 nozzle on the Mk3S

The V6 nozzle seems to get this issue of filament stick which not only dirties the nozzle but also causes print issues. I don't have this same problem on a Mk8 nozzle on my Ender 3. I assume a Mk8 nozzle would fit on a Mk3S but thought I'd ask here if anyone has done it and if there are any problems with a Mk8 on a Mk3S? Thank you.

Best Answer by JoanTabb:

Mk 8 has a shorter thread, which will lead to leaking between the heatbreak and the nozzle unless you rebuild the hot end, if you rebuild the hot end, the gap between the heater block and the heat sink of the cold end will be smaller, not a good solution

RE: Mk8 nozzle on the Mk3S

What if I mistekenly already put in the mk8 nozzle.. 🙄 (on a mk3s+)

and tried to extrude..

and actually extruded quite well (just the "load filament" amount).

What shoud i do? 

Shall I order a new hotend or is there any hope that switching back to the correct nozzle I may not have issues?

RE: Mk8 nozzle on the Mk3S

Update:

Got the right nozzles, first problem is I cannot use the "change nozzle" feature because the mk8 one crashes on the bed so the printer shuts down..

I'm going to try manually setting the axis and temperature, only question is about the fan: I can only set the one on the front, which I'm going to unscrew to have more working space.
