There is still that trick of checking that the bowden tube for 2mm minimum ID. I still push a piece of bicycle spoke through my tubes to qualify them. Too much stock doesn't meet this requirement.

btw Kiza how much height in Z did you loose with the whole conversion?
I guess bed can be optimized somehow still?
For those of us not needing ABS printing for example.

It's around 2cm in this version. It still can be optimized, the final version is original Cube 3 print bed with PCB heater glued from the bottom. Holes in PCB will serve as table stabilizers. Something like this:

And finally, testing Print Head MK6:

it just dawned on me, how is the extruder being held in other than just the PTFE tubing?

The original extruder (gears and cap) is fitted in the extruder case, the other half of the extruder (with logo) is placed on the outer side of the case. Screws go all the way through the case into the other half. Plastic 3mm tube from the cartridge goes through the half of case into the fitting. Normal PTFE tubing is fitted into the other side. On the bottom of the extruder there is a thick tube from the cartridge inserted for convenience.

I see it now, shouldn't have jumped to it without studying it. Do you remember what length screws you used?

So they're technically "perfectly level" on "factory" design?
