I am thinking about UMO direct drive solution. I've found here that prefered one is with stepper motor directly connected to the shaft (letter A on the example). But what about hiding motor on the back of UMO and connect it to the shaft directly via 2 identical gears ((letter B on the example).

examples here:

What are your opinions about solution B? is it good/bad etc? what are its prons / cons?

I am a big fan of your thoughts about hiding away the stepper motors... Them sticking out, on the outside of the printer, is my main reason for not doing a direct-drive setup...

Regarding your design, you would probably want to use something like a herringbone gear to avoid any play in the gears when turning direction... I would still be afraid that the gears could be quite noisy when printing at speed, maybe you can compare with some similar setups like the Tantillus:

great example, for such setup, haven't seen this printer before.

About noisy gears I think I can print gear covers to hide them and reduce noice if it will happen. Gears on the image are only for example purpose. Herringbone gears are must as you said.

I think about the setup in which one motor will be geared (for the back shaft) and the second probably connected directly to the right shaft. I want to remove motors from inside of hot chamber which I will probably make some day, and hide them on the back of printer.
