Has anyone tried adapting a Mitutoyo DRO for use with CNC milling machine. I would like to use the linear scales I already have mounted on my machine. Talk about zero backlash. Found a pdf file on Mitutoyo site on scales, will study it and check against my hardware. I was hoping I would be able to plug directly into the recorder outputs.  |

| Mitotoya usually can be adapted as the ones I have used have had +5v differential output. You may have to reverse engineer the channels, IIRC the + and common is red & black so just power it up and check with a meter or scope. Al

| As I recall, I think I bought the less expensive ones which would be the 5s, so about .0002in, way better resolution than I need. Thanks Al |

| Hi Al. I got some responses in the electronics section, and a note back from Gecko that the motors will oscillate the amount of the backlash in the machine. Have you run into this problem? |
