Hello,

I have set up my newly built Root3 CNC router, have configured the A axis to be slaved to the Y.   When I jog in the negative Y direction, it is smooth running, but when I try to go the opposite direction, it seems like the A axis is either continuing to try to jog -Y, or just missing steps and not keeping up with the main Y, leading to a racking of the gantry...

Any help greatly appreciated....I am running the red RNR USB motion board, which I know is low end, but this is my first go at CNC, so I wanted to start low in case I let the smoke out...thanks!
