I am starting to use an old Voltera V one I have in the laboratory. As my collegues told me, the machine may have more than 4 (not known) years so, it is out of the guarantee. The problem is that I have found that one of the positioners is very loosy and it can be even move out od its place easyly. Also I have found that the spring in the z min switch sometimes gets trapped, maybe due to the dirt. Thus I was asked to find some replacement parts, at least for the positioners, or craft one by myself.
-Do you know if Voltera sells that part alone or any other place I can purchase it?
-Has anyone faced similar problems?
