Hi all - just a quick update...
I managed to get a square wave o/p from the original encoders using a
high-speed comparator as Jon suggested. It works ok but every now and then
stops working or seems very erratic. I know the original Pumas 'folded up' on
themselves occasionally due to encoder problems, so maybe there are problems
with mine. Bearing that in mind, I think it's going to be safer to swap them
out for modern ones. I've been looking at the USDigital E5 (see
http://www.usdigital.com/products/encoders/incremental/rotary/kit/e5/ ) which
give A,B and Index square wave o/p's. Has anyone used these or can you
recommend another type please? The originals have 250 counts so I'm guessing I
should go for the same.
Thanks
