So my printer is built and corexy (x and y axis) works wonderfully. Wish I could say the same about the Z-axis (I use 4 smooth rods and two 8mm threaded rods connected to two motors via flexible couplers). It seems that many corexy printers lack good Z-axis (for example many use cantilevered beds).
So what would be the best configuration?
*Two leadscrews connected to a single motor by a belt?
*Dropping screws and using just the belt like on this solution? [www.thingiverse.com]
*What about linear guides/smooth rods? Are not 4 of them overconstraining a plane? Maybe use 3 of them? 2 seems like a big no-no in my book as it makes a bed cantilevered.
*Sli3der seems to perform great: [richrap.blogspot.dk] Maybe use a spectra line? For some reason I feel uncertain about it and belt seems like a more robust solution.
So what are your ideas?
