Warning
If the k
factor that you select is too large, the system will oscillate around
v
the forward-fed nominal velocity value.
Unlike operation with following error, you must also enter the optimum k
factor for each axis when operating with interpolated axes.
You can selectively increase the contour accuracy with a higher k
k
factor is activated with M105:

In MP1515.x, define a second set of k
M105.
M105 also influences compensation of reversal spikes during circular motion.
With M106 you can switch back to the original set of k
