Smoothieware based CNC router

Hi guys just after some ideas what would be the best way to implement a Z touch plate in a Smoothieware based CNC router setup?

Imported from wikidot

Just wire it and use it, there’s nothing complicated about it :

Mine is just an aluminum block with a long wire to system ground and then another long wire connected to the probe input and alligator clip. Measure the height of your block, clip Probe lead to your endmill run touch GCode which has the offset which is your block height.
