Subject: Re: [Emc-users] mesa 7i76 spindle encoder not counting suddenly
actually I just found the A and B inputs in the Hal configuration window
the B input changes from red to yellow if I put some force on the table and
try move it slowly.
but the A input doesn't change color at all.
is that expected with a problem like this?
Yes, if the raw counts only change going back and forth by 1, it usually means A
or B is not changing
thanks for the reply PCW
hey is that different to just checking the raw count in Hal?
what pin am I looking for? and can I monitor it from the Hal
configuration window?
regards
Andrew

You should also be able to tell whether A or B is not changing
by looking at the encoder A,B pins in hal
