Hi Tom,

I wanted to know how to reverse an axis direction in kmotioncnc so that when I go right it counts down while now it counts up. I tried inverting the signs on both the input and output channels but this does not work and could not find out how to do this.

Secondly, I am having problems with my limit switches. I am using the general purpose inputs on kanalog (bits 128-135) which have hall sensor limit switches and a negative logic (it goes low when the switch is triggered).

Do I need to include anything in my init file such as setbit etc. as I cannot get the machine to work when I configure limit switches. The axis is simply disabled or will not move. If I set the limits to 0x0 then everything works. Also, do I need to worry about setting anything if using limits with master/slave axis.

Thanks

Hi Tom,

I also wanted to mention that I can see when the switches are triggered in the digital I/O screen.

I'm not sure about your limit switches, but you can try adding a minus sign to the counts/inch number on the KMotionCNC trajectory planner screen to reverse the axis.

Not sure exactly what you are trying to do, but hope this helps.

Thank you8, I will try this.

To clarify all I want to do is reverse my axis direction to have the y 0 position on the right instead of the left of my machine. This way it is easier to visualize when doing cad.
