G0704 (BF20) Limit switches

I decided to go ahead and install limit switches so I could do the TTS repeatable tool holders, probe and MSS (Mach Standard Mill) implementations at once. I am very sick of touching off after every tool change!!

As per the request below, here are the .STLs for the mounts.



The switches are repeatable to below 0.001" on all axis, works for me!!
