Roger,
See my issue, also:

I've tamed it a little by tightening the absolute crap out of everything.
It's manageable for now until I have the funds for a proper focuser.
It irks me that the STL/FSQ/Robofocus system was ubiquitous for so long and only good things were ever said about them. Mine's been nothing but trouble.
I've got it down to missing 5 position units per focus run now.
