Antonio

A handy tool that might come in handy for aligning the two bars of the X axis to the tabletop is a comparator COMPAC with an analog diameter of 37. You can couple the two filetted bars to the hundredth using this comparator. On February 27, 2018, it was transformed to use all types of comparators. It has not been printed yet ... as soon as I can, I'll let you know;-).
