Interesting stuff. I'm wondering now about just ditching the threaded rod and going with a cable driven Z. I hate the idea of loosing resolution in Z though.. Anyone consider gearing the cable Z down with some belt driven gears?
Robonz, can Is that some kind of cable tensioner inside your XY end? Something like that is top on my list of upgrades.

Here is a side by side comparison of a challenging print that is 100mm tall. You can see the banding on the back of head is pretty much gone.

I would also prefer a belt to a string for the lift as servicing is less fidely.

Talking about belts and pulleys, anyone tried replacing the gears in the extruder with a belt stage? I still have some more pulleys and belts lying around.

I'm actually working on that now. I considered modifying the original extruder for belt drive but decided on something completely different. I'm attempting something similar to what the ultimaker uses with the stepper motor and extruder mounted up high behind the machine. This will have the added benefit of a considerably shorter bowden tube. I have the extruder body printed. Now I'm working on printing some GT2 pulleys. I already printed a set but darned if I can't find a local source for the M3 keeper nut that the pulley was designed for. I will print a new set of pulleys and hob the new bolt tonight.
