Blimey the more I read about limit switches the more confused I get..this is my breakout board these are the limit switches please can someone help me?
First of all, if that is not an up to date Protoneer CNC shield, it will not have the right pinouts for all the limit switches. That they are obsolete is not something the vendors selling Chinese knock offs ever seen to mention. If it is a Protoneer board then it should be fine if it is a version 3.51 -- which only costs $14 -- then the pins will be right. Refer to this for limit switch information. gnea/grbl. Your vendor should also have provided hookup info.
