Thor, or should that be Zeus?

Some update pics of Thor. Need to finish the enclosure and 4th axis / lathe setup.

Does anyone know how to deal with dual probes, on NC and one NO, going into the same probe input?

Can I run two probe inputs?

This is the issue, how else to wire this (goes into CS Labs) input 3.

you could use a relay on one output to get both of them to NO or NC

I've been thinking about exactly this problem for my own machine (also using CSMIO). I haven't built the touch probe yet but I was intending to use a simple bit of circuitry to invert one of the signals and then combine them. I'm not sure that you can solve the problem without adding something outside the CSMIO as it only has one input that is suitable for the job.

You need to invert the NC signal to NO, otherwise the probes will interfere with each other if run in parallel.

My preference is to run probes NC, as then any circuit failure triggers a stop, but then you'd either need a switch to swap between probes, or wire them in series.

Either would be possible with a transistor or two, and a couple resistors.

I emailed the probe vendor as the tip is not concentric. He responded with some info on how it can be calibrated. I then searched and found this - http://www.machsupport.com/forum/ind...c,17766.0.html - Whilst this doesnt fix the actual issue, it looks like I can use the same prob or perhaps two of them for different uses (I bought two as I was importing it from the US anyways). Perhaps next time I should pay attention to the other stuff in the box.

What probe did you buy?

One thing you'll need to check, is what voltage/current the probe is designed to work with. I made up a small interface board for my probe, so it was only switching the designed 5V, so I could use it to switch a 24V opto.

Two of these, almost a year ago, lol.
