I have a some questions regarding the 4th axis configuration:
- what is the standard for setting Zero in this axis? in one of the extremes of the screw or in the middle?
- how do you reference this axis at startup?
- the 4th axis is supposed to go around 360 or a little more? (or a little less?) Using my "eyemeter" it seems its some degrees short of 360º
I machined a wood piece and made a small video (will upload in next post) but I didn't finished the piece because of these doubts.
Thanks in advance
