Z axis travel/ Program exceeds machine maximum on axis Z

Beside incomplete .ini file JOINT3 and JOINT4, if retracted Z-Axis is home zero, try this entrys in AXIS_Z , JOINT_3 and JOINT_4

MIN_LIMIT = -5
MAX_LIMIT = 0.001

Tried that and linuxvnc errors out stating a problem with axis z max limit.

Not sure what you mean by incomplete joints 3 &4

To the other note the machine has 1x, 2y and 2z joints. I don't think I'm missing one but let me know if you feel that's incorrect.

In the ini file that you posted it looks like the Z joint looks incomplete plus if you have 2 motors on Z you need a joint for each one

I tried setting my z home to be 3 inches above the table. When I run the program it still gives me the error and if I proceed it plunges right down and stops at 0. I'm sure I'm doing something simple and stupid.

The ini and Hal files are straight out of pncconf so I'm not sure how q joint or joints would be incomplete given there were no errors. I've modified again through pncconf but still don't see any issues.

Perhaps I figured it out. If I hit touch off and enter 1" z height then the machine drops to 1 inch and starts running through the cuts. This is great!

Then if I reset home to be 0,0,0 restart and touch off to 1" I again get the same error that my z exceeds the negative limit.

How is the z typically set up and what is the typical home position?

According to your hal file Z is showing that you have two joints BUT you only have one joint for Z in the ini file.!!

How are you homing. It seems you don't have home switches. If this is a gantry machine it would be good to have home switches so that you can auto square the gantry.

The Z is normally home at the top with Z- going down.
