Auto Zero Plate/Ports and Pins
« on: October 14, 2015, 03:20:35 PM »
My machine came with a wired touch plate (or offset block).  I've had the machine for 9 months now, and never bothered to try to set it up because it would activate the E-stop whenever contacted.  I've just been zeroing Z the old fashioned way.  I decided it would be nice if it worked and have been doing some searching.  There are a couple of good YouTube videos explaining the setup, and I tried to follow that process.  The first thing I noticed was that the PIN# for both the E-Stop and Probe is 10.  That would make sense with the probe behaving like the E-Stop switches.  I'm not sure why it would be installed that way, though.

I downloaded the Auto Zero programming text that was attached to one of the videos (and seems to be available many other places).  It works until the contact is made.

Is it safe to assume that I need to rewire the touch plate to another PIN# on the breakout board to isolate it from the E-stop circuit?

Mine is to pin15, make sure you assign the pin in config as well.

Yes, as long as the probe and estop share a pin, you'll never be able to probe. Nothing else can share the estop pin.
