4th Axis Problem
« on: February 07, 2019, 03:50:58 PM »
I'm not getting it.  I must have something in my Mach3 profile that is set incorrectly.  Check out the GCode below. A follows X except when A is supposed to go to 1, it goes there the long way 2->360->1.  It's like I can only go in the positive direction with A.  I have "Rot 360 rollover" and "Ang Short Rot on A0" set in my general config.

G01 X2

G01 A1 (this goes from 2 to 359 to 1)

Ok, it looks like when doing a G01, A-axis can only go in the forwards direction.  Anyone else see this?
