2010529If you hit a limit switch on a cnc mill the part is probably going in the bin so we never hit limit switches they are surplus to requirement heehee So any limit switches fitted are actually homing switches and your only priority is repeatability It must always switch at the same position Reed switches cant do it.

Limit switches we dont need limit switches I am new to CNC machines If you are anything like me you want to make chips as soon as possible Once I had the bare minimum setup on my CNC mini mill conversion I wanted to see chips I installed the CNC Fusion kit and dialed in the motion on the x y z axis I even trammed the mill.

201226Finally I have been trying to decide on some prebundled cabling with anywhere from 9 to 25 conductors shielded and insulated so I can run for example one cable for the jog and other capabilities from my console to the the ReadyToRun box and another cable that has all the homelimittool length signaling from the mill to the RTR box.

The simplest way to do home switches is to wire them all in parallel using a single port pin You can even wire the probe switch in parallel with home switches too but I figured itd be nice to have separate jacks and besides the controller still has a few port pins left.

Home and limit are different things Home is an absolute reference for the machine and limits are just that Some use the home switch as one of the axis limits but I do not think thats such a great idea I guess it depends on the individual That does seem a little steep for home and limit switches But yes they are needed.

201941The only difference between homing and limit switches is one of terminology which is often confused quantity limit switches in the physical sense come in pairs except maybe the Z and position homing switches as noted are all at one corner while limit switches are paired one at the end of each axis of movement.
