I am setting the prox switches for my shopbot . X axis went well , but I have questions about the y axis. The table is centered between x- rails. The end stop to the right of the y motor stops the bot at about 3/4" past the edge of the table. I had to set the prox switch inside the stop so I now have 1/2" clearance. That is with the stop pushed as far right as it can go. On the other three sides I have a clearance of 2". I am concerned that with a large cutter head I will not have proper clearance.
Also are proximity switches used to set a home position , are there any suggestions of other methods?
