Where is Z Min Position

Hi

Using single Arduino electronics

I am hoping to use an existing CNC mill with an extruder mounted.

I am currently setting it up.

Which is the Z min position? Is this at the top of Z the stroke?

I have it set this way but when I home using stepper excerciser it ignores the upper microswitch but stops if I press the lower switch.

It may be I have the switches the wrong way round.

All switches are working when using the switch test software.

Hi

Answering my own question.

The switches are correct but I had the axis travelling the wrong way. I read the cartesian instructions forgetting that the equivilant to my head lowering is the Darwin table rising. I was expecting the Z home to be at the top of slide travel i.e. as far away from the table as possible as this is the norm for CNC machines.
