From last week's episode...

The result is surplus torque and steps/mm, so the next rev can use a larger diameter to get more (all?) of the string wound onto the drum in a single helix of more nearly uniform diameter. Currently the steps/mm changes when the string fills the (thin) drum and winds back over itself [...]

So... yes.

Z v3.01


In this iteration:

(...and that little screw on the right frame side -- for stowing the counterbalance rig -- can go away now)


While assembling this rev I made a short list of minor tweaks for one more iteration that should be ready to share (because optimism).
