Z-Axis Rotary Arm, Tight Clearance to Lead Screw – Is This Normal?
I recently replaced both Z-axis linear rails on my XL and noticed something during reassembly that I hadn’t paid attention to before. Prusa sent me the parts, so to my knowledge everything is compatible and fits.
On the right side of the printer, the fastener that attaches the Z-axis rotary arm sits very close to the Z lead screw, about ~1 mm by eye. There’s no contact, but the clearance looks tight enough that I wanted to sanity-check it.
Is this this normal, or should there be more clearance here?
