Title: Mach3 mill spindle rpm reading?
Post by: NorCalZ71 on March 02, 2013, 02:16:54 PM

I finally got my spindle running under mach control. But the rpm box is always 0. It shows what the rpm called out should be but not actual rpm. I kno I need a sensor to pick up rpm and I have added a single slot disk for the sensor but I don't know what sensor I need. Or how exactly to hook it up. Will this show actual rpm in that box?

Most use a switchg like this I think.  http://www.mouser.com/ProductDetail/Optek/OPB910W55Z/?qs=sGAEpiMZZMvQY0bpacMSodxFvo3SCOucBf2I2hQ%252bRnY%3d  I did not check the specs but this should give you an idea of what to look for.  You just need a switch that is the right voltage for your set up and can read as fast as your spindle can turn and wire it to your index input.
