If you have an ESR meter you could pull caps and check against new ones. Or
just go whole hog and replace them all.

At 27 years old, and not running within 5% of their rated voltage to
keep them formed, I'd go the whole hog route. I'd scope for ripple first
but it would not take much to convince me.

[EXTERNAL EMAIL] Be sure links are safe.
Hello guys, I hope you're doing well
I'm having problems with a Daewoo Puma 12L lathe to index some tools.
The
problem is that some tools work well and others don't seem to be
detected
by the control to stop at the position and clamp the turret. So the
turret
keeps rotatring until the timeout triggers.
The lathe is working now because some turret positions are usable. But I
would like to try and detect the problem in case it's the encoder,
because
they seem hard to find. Are you familiar with any of these? My idea in
case
the problem is the encoder is:
1- Replace it for the same encoder (which I can't find anywhere)
2- Use a 100 pulses abs encoder and scale it via a microcontroller to 10
pulses to accommodate it to what I need. Then feed those signals to the
control. (The problem is I only found a basic manual for the encoder
with
the pinout, but nothing about how it behaves, I don't know if it uses a
BCD
or plain binary, etc...)
Of course in the near future this will be converted to LCNC and none of
this would be a problem. But in the meantime I would like to have a
backup
in case the encoder fails completely.
Thank you!
