+Sean Connolly When the gears are mashed properly, none to speak of. Same as properly tightened belt. If the gears are too lose, yes backlash!. If they are too tight together, you get a tooth width pattern on the print, but still no backlash. :)
What are the calculations used to design these gears? I can't figure out how to get the dimensions on the rack correct to mesh properly with a pinion like this.
this is great, nice job
Any measurable gear lash? I really like that self-centering helical cut. Fantastic bit of design work, that!

Do you have any more pictures of the printer as a whole? And I love the extruder/x carriage design, is it on Thingiverse?
