That could be related to play in the saddle gibs.
Has somebody made a lead screw to be installed in the middle of the bed ?
I have looked into Youtube, but not found what I wanted.
The problem is twisting of the saddle when I return the clock wheel cutter.
( 144 teeth on an 88 mm diameter plate gives not much room for error)
The leadscrew shall be manual twisted.
