Foldertech 2020 Y end stop

Simple and very solid Y axis end stop for Folgertech 2020 printer. For use with reprap discount end stops but others may also work.

Still allows for height adjustment by simply rotating the end stop.

NOTE: This requires holes to be drilled to mount the PCB. Mark holes as required and drill low speed.

Works well with sonnylowes Y axis upgrade located here:
