Re: [CAD_CAM_EDM_DRO] limitswitch set up

Bernard,
would you happen to have any JPG's of your set up? Sounds pretty straight
forward but you mention the radio shack boxes are slotted at both ends?
Do the blades move with the table with the boxes [3 of them with one
containing both an X and a Y switch??] mounted to the base?
Lastly do you have the link for the purchase site?
Sorry for all the questions but this is my next step in the Loooooong CNC
conversion process.
