How do I check to make sure that quadrature filtering is turned on? Is this a
config modparam statement that goes in the ini file?
Can you give an example?
Are you using m5i20 (hostmot) or hm2_pci/hm2_5i20 (hostmot2)? If you're
using hostmot2, you enable encoder filtering in HAL

I'm not sure how the m5i20/hostmot driver handles this...
the old driver simply has this setting hardcoded, and can't chage it
without a recompile. I forget what value is hardcoded, though.

What you are pointing out seems to imply that
you are concerned about noise in the lines. It looks like I am going to
physically connect some test pigtails to the 5i20 in the controller so I can
scope what is happening in the signal lines

Only if upgrading between major versions. I didn't see whether that's
the case for you or not.

The newer Mesa drivers have an estimated velocity output, which should
be pretty accurate. The scaling (*60) should be able to run in the
servo thread just fine. I'm not sure when the velocity output was
added, but I'm pretty sure it's in the hostmot2 drivers

Is there a new signal name for this?
The new pin is called encoder.XX.velocity.
It's documented in the hostmot2 manpage, which gets installed
