KMVAR should be set to the Var assigned to the KMotionCNC S Action.
Previously I noticed in a screen shot it was set to 113 unless you changed it.
PC_COMM_CSS_S is defined in PC-DSP.h as 113
So you probably want KMVAR defined as PC_COMM_CSS_S
Previously KMVAR was probably incorrectly defined to 1 in places where it wasn't used.

I think we are off by a decimal place in the FACTOR:
8192 * 26/18 = 11832.8889
