There are options that do not involve replacing a small part.
(1) just add an external low side resister (SMT parts are easy to remove) or
(2) if the pressure sensor is actually a pressure-sensitive resister, then
run it with more than 5 Volts.

Or, less intrusively, boost the signal with an Op-Amp powered from the
field power?

Greetings Peter;
The 7i76 has, I recall reading, the ability to do analog to digital
conversions on the first 4 of its inputs. But the full scale range is 36
volts if I recall right. I don't recall the bit range, though, whether
its 8 bit, or 16.
Would it be possible to lower the full scale r

The step-gen won't make steps until it sees the new target. So running

Greetings Peter;
How hard would it be to convert the joint.#.free-tp-enable into
move-is-in-progress signal?
Prowling around with a hal-meter, I found this signal is true for the
duration of a keyboard jog, but doesn't react during an gcode move from
the mdi command line, or a keyboard jog aft
