axis configuration

Hi - I'm very new to the world of CNC and also I've just joined this forum so a big Hello to everyone and I'm hoping someone here can give me a helping hand.
I have a very small cnc - a Proxxon mf70 - controller is a Gecko G540.
Although I have had some success in solving little problems here and there i just keep finding more and more issues that are hard to deal with.
It took me ages to even get anything to respond but I feel like I am almost there.
Just to further explain - I have only 3 switches on the cnc - one at the top of the Z axis and one at the motor ends of X and Y.
So I thought I would combine the switches onto one pin - so in the stepconfig I chose 'all homes' - the switches are NO switches.
I have today managed to home all the axis but I don't think it is right as I cannot jog the axis after homing. Well I can some of the way and then they stop.
Below is my INI file for someone to peruse and maybe offer some suggestions.
Thanks in anticipation.

Thanks for your response - I will try that tomorrow - as I am in the uk it's now time for sleepy time! Maybe I can think straight in the morning

Ok - applied your settings to the X and Y axis in the INI file.
Eventually got the homing completed - however, I cannot now jog any axis.
I can move toward the last bit left of the way and then reverse to a point only about 5mm from the end and it stops.
Still something not quite right.

Hi

Any help appreciated
