Thanks JR and Paul. Great ideas, tips and sources! Yuri's website is pretty interesting and a wily EE. His thoughts on noise and the issues are good and true. On my drill machines I used a lot of shielded cable and very careful about ground loops, most of it was RS485 but all the various voltages 230 3ph to 24VDC and motors, servos, solenoids & actuators, plus a computer were a challenge with routing and lengths. One other simple thing I found helped in some cases were ferite cores at the ends of the cables...cheap and cheerful.
I've eyeballed the iGauging stuff for a while now but haven't jumped the cliff. A friend did and ask me to check his out when he got it. What I found was they are pretty darned accurate and repeatable (my main concern). I ran his through the ringer off and on for a couple of days with every test I could think of and for the money, well worth it IMHO. I may help my brother put a set on his Grizzly G0760 instead of a Glass setup from DROPros for ~$7-800 (~1/2 the price the Mill) we've been talking about although a lot more functional with Math and toys in the display and good to 2 tenths...nothing his mill can do yet but nice. The nice thing about these guys for me is they are about an hour from me, no shipping other than the drive and factory visit. I do like the challenge of building it for half that and Yuri's kit may add the functionality for only a few more bucks.
Nice setup JR and thanks for sharing and verifying the functionality over time.
