Ho all,
So I managed to get an X-axis limit switch installed and working. I also managed to set it up as a homing switch so I figured out that bit. But I do have an issue.
The limit switch I installed is on the X maximum - so when the carriage is the farthest away from the workpiece axis. To my way of thinking, the home position should be *away* from the work. Not only is that safer in general, but it strikes me that if something were to happen mid-job (power failure, lost steps, etc) that the ability to home the machine with a workpiece still fixtured up would be super useful.
However, when I hit the "reference X" button, the machine started traveling in the other direction - towards the workpiece. So that must not be standard practice.
There must be a way to tell Mach 4 to home to X Max, and there must be a way to tell Mach 4 that X Max is N many units away from zero, so that homing to X Max sets machine zero.
How do I do this?
