MACH3 g43 and g54 post process problems

Hello,

I am new to CAM and more specifically fusion 360 CAM.   I am running MACH3 as well.    My problem is after I have homed and zero'd my machine and start cycle the machine runs the program offset left during the 1st facing operation at the correct Z and then during the 2D adaptive operation runs approx .5" high on the z with the same left offset.    Same tool in both operations.   From what I have read this may be a G43 and/or a G54 problem in my code.   I have changed my post process to .tap file extension and do not use G28 and that has helped my "bad character, K word" and Z crashing problems.    My question is how do I set up my post process to eliminate this "offset" or is this a setting in MACH3 I need to adjust.    I do not want to edit code on every program I run if possible.   This seems very time consuming and considering the fact that I don't know what I am doing I feel it sets me up for more problems....

 

I tried to post the code but it wont let me attach a .TAP file  Is their a way to work around this?

 

 

Thank you for your time.

Josh

@ANDERSONRODANDCHOPPER just one thing when you home your Z it should activate the switch then back off the switch then Zero the Z axis machine home so when it does the G28 it should not crash.

if it does you have backlash or losing steps or it is not backing off properly.
