Help, Completely stuck on Homing Problem

I have a 5 axis gantry style CNC machine XYZCA. The first 4 axis home correctly, but the 5th has a problem.

At first it appears to home correctly, the home offset is applied to coordinate as set in .ini and no errors pop up, but on closer inspection the little homed 'crossed circle' icon is missing in Axis (see pic) and then an error msg appears if I try to go to the MDI tab (see pic).

Hopefully someone more experienced can help with this. .ini and .hal files attached.

Hi,

Thanks so much for your reply, It seems to have helped but I still feel like something is not right.

Now when I use Machine->Homing->Home Axis A (in Axis, see attached image) it homes C (joint 3) instead of A. Also I notice that it wants axis B to be homed as well, which can only be done, by clicking Home All.

Incidentally it is a 5 axis XYZCA bridge mill, it has no tilting/rotating tables etc. I have used a modified version of 5axiskins.c for kinematics, it has not really best tested yet, as the homing issues have held me up.

Any ideas would be greatly appreciated!
