Magnetic encoder woes

[macardoso]

OK, tore it down and inspected. found no problems. Clearances were perfect. Added a conical spring and rebuilt the shoe to make the head ride just right.

put it back together and problem is WORSE. Put logic probe on galil channels quite a bit. Channel A+ is not always putting out a signal - just intermittent. The worst kind of problem.

Time to quit putting good money and time after bad. The whole thing goes in the trash bin.

Can you suggest a complete scale compatible with Galil inputs?

PS got a magnetic read head and tape free to good home. there is a chance problem is elsewhere.

I'd take the scale and readhead. I have an oscilloscope and have fun laying with "projects". I'll pay shipping!

Not sure what to say Karl, sounds like you just got a bad read head. I have installed these on 5 machines and have had no problems. I have never heard of IBB however, always used Renishaw LM10 or Ditron DMR-200 units.

Any scale that outputs a 5V quadrature signal will work with the Galil.
