Quick mini survey. If you have a knee mill, where have you mounted your home switches? I understand it doesn't matter because the machine coordinate system is only used to establish a fixed reference. For the rest of the time we use various world coordinate systems with the G54...
So the switches: For the Y axis so the bed moves towards you or away? For the X axis so the bed moves to the left or to the right? The Z axis obvious because we always want it to move away from the tool tip to avoid a crash. For example, if you periodically put your 4th Axis on the left hand side of the bed it's probably better to have the system home so the table moves to the left. In effect this makes the tool move to the right Just in case you ask it to home but forgot that you had the 4th axis bolted down. And that brings up the third question about a 4th axis. If you have one, do you tend to put it on the left just like a lathe spindle or on the right? Any reason for the preference? Often there are tool changers on the left so it makes more sense to have the 4th on the right.
