Hi,I'm having trouble with the limit/home switches on my CNC home built,purchased a full licence for Mach ,have Geko g203v stepper drivers all was going well steppers drive, wired the Limit/Home switches so that if a wire is broken It should stop the machine,.After 4 weeks on and off trying to set the jumpers I am at a loss on how to set the board  to see the limit/ home switches in Mach .I have a Homann MB -02-V6 breakout board ,Hoping that some one may be able to shed some light on how I do this having already mastered this board ,i would be most grateful .

Can you please tell us in what locations you have them hooked up. A picture would help tell the story also. I have 3 of this model of Bob from Peter. They work very well. Have had them working well with pp/usb ss/Ess.

Usually Peter responds, might be worth sending him a private message flagging this post.
