Ref all home issue? A hand would be great just here!

It's possible the bob inputs are seeing a blip from the switches caused by noise perhaps, too fast for you to see. If you go to the Mach3 Ports & Pins / General Config page, at the top right is a setting for, 'Input Signal Debounce/Noise rejection', it will likely be set to zero, try entering a number to see if that helps, the general idea is to have the lowest number in there that works.

No don't do this unless you really have to.!! . . . . It's a last resort thing and you should find the cause first if possible. Which will be poor earthing or wiring.? . . . . I doubt it's that anyway if it's tripped all the time because noise doesn't do this it's an intermitant thing is noise and tends to happen while working or spindle running not stood still and mostly to affects limits more than home switches. If noise is affecting Home switches then you have a decent problem so needs fixing and de-bounce isn't the cure.!

Hi Jazz and Eddy

Many thank to both of you for the help. I think it was an E-stop of issue ofsome type. Something let me to the e-stop and it seemed to solve the issue, Ihope there is not a fault on the way with it.

Thanks again and happy machining
