X4+ 4 Axis

[Martin Long]

I need to engrave a scale onto a 30mm dia. material, the scale is quite simple 0-50 in 10,5,1 increments just like a circular 150mm rule only 50mm. long.
I'm using BobCam V21 and Mach3.
In BobCad I have done the usual drawing as a rectangle the length of the circumference, the index distance between each line is around 1.8mm which is around 2deg.
When I run the programe on the mill the 4 axis always indexes to the long direction, instead of moving from A63.2 to A61.2 which is 2deg. it moves 358deg.
How do I make the axis travel to the next cut in the shortest direction without it doing almost a full circle?

Fiddle with the ticked boxes in the large Mach3 config page.
Ther is one marked shortest path/rotatin or something like that.
With a bit of trial and error it will go via the shortest rotation.
In the general logic screen set the A Axis to angular.

Neil,
Thanks for your response, would it be in General Logic Config. "Ang Short Rot on G0" ?

Neil,
I tried what you suggested and it works a treat, thanks!!!
I have just engraved the scale, tomorrow I will try the numbers.
Thanks again
