Does anyone know how to tighten the clamp base? While I was calibrating my machine, the moment I pulled I noticed that the clamp base was moving even though it was already locked
There should be a screw with a hex head on the side of the clamp base (about 7 o-clock position on the picture) You may need to rotate the base a bit to expose the screw head deep inside the base.
A six edge key on the underside of the clampbase and hold firmly...at the same time you take an insect wrench on the top (on the handle as in the picture) and tighten.
