Was there a DRO project in Nuts&Volts?

Post by SteveA220 » Wed Aug 26, 2009 1:14 pm

It seems to me there was an article on a homebrew/DIY DRO (Digital ReadOut) for a lathe or milling machine in the last year or two in Nuts&Volts, but I can't find it in my stack of back issues. Does anyone remember this? Could someone point me to the issue, maybe, or maybe tell me my rememberer needs service so I can stop looking?

Thank you,

Steve

I went back to Jan of '06 and went forward. So far, all I have found in the TOC's
is the Dec. '08 article on the Probotix Fireball CNC machine and the July '09 article
of the Probotix Fireball Revisited. No other mention of CNC or milling/lathe.

Oh well. Thanks anyway. Guess I was imagining. Or if I saw it somewhere and have the magazine wrong, it's another case of not having a use for it when I saw it...

Thanks!

I don't know about magazine articles, but I put together a nifty little 2 axis dro using the propeller chip, 2 encoders, a 2line serial lcd display, two pushbuttons, and a 6v battery pack.
You can set the scaling for each axis, which is then saved in eeprom.
You can zero each axis.
It would be easy to expand this to 3 or four axis by going to a 4 line display and adding 2 buttons.

The spin code for my dro is here

Parallax has a quadrature encoder object for the propeller on its website, which my program uses

The propeller couldn't be easier
