Z axis control in G code and THC
« on: October 22, 2018, 02:53:29 PM »
I am using the Fusion 360 post processor and enabled Z control in the post options.  I am trying to get THC to work properly.  It seems that the Z axis doesn't want to go below the Z height set in the G code. Does anyone know if this behavior is what is expected or am I looking at a different problem?  The Z seems to hang around 0.6, but not exactly (within a few hundredths).  Thanks for any insight.

Example:
N10 G90
N15 G70
