I got the chip on a board.
I have located it. I have a 3 axis unit in a box, and a spare un-used Arduino board. Both these A-boards are from Texas Instruments.As I recall, you have a VFD in your shop. I have two expensive Teco units in my shop. They are RF noise monsters. Input filtering and double shielded output cable seems to solved most of the problems.
Did you return your touch unit? If not, wanna sell it?

Make me an offer
I can't remember, there may be spots on the board for a forth one, but 3 is what I did. It used iGaging scales. I had a Busy Be knee mill and when I sold it I put the iGaging reader heads back on it and kept the Touch.That's awesome!
I'm in the Chichimaun Ferry line up right now heading north for my youngest son's wedding. I seem to be able to do some things here but as soon as the ferry leaves, I'll prolly get cut off and might be off line till next Wednesday.
In the meantime, I'm surprised to read your DRO is 3 axis. I thought TouchDRO only came as 4 axis with optional RPM.
Can you tell me what scale technology it was setup for?
