Hi I have set up limit switches  in NO configuration on a 6040 chinese router. I cannot get Mach 3 to recognise the switches. I have tried many different settings in ports and pins without success. Machine has a Bitsensor bob HELP

Hi,
your post belongs on the Mach3 General Discussion board, this board is for Mach4.

The Bitsensor  controller board, also called the RnR controller board, is famous for giving people grief trying to get them to work, they
are in short Chinese crap, you've got what you paid for.

They do not work with Mach4 at all.
