The pyvcp panel is not looking at the encoder velocity but rather the
commanded spindle speed: spindle-vel-cmd-rpm-abs
commanded spindle speed: spindle-vel-cmd-rpm-abs

I would probably link the spindle bar chart to
hm2_5i25.0.encoder.05.velocity-rpm feed
through a lowpass filter and the absolute function
(I can't read you .rar file now for some reason)

in the main hal file:
net spindle-vel-fb-rpm <= hm2_5i25.0.encoder.04.velocity-rpm => abs.spindle.in
net spindle-vel-rpm-abs <= abs.spindle.out => lowpass.spindle.in
net spindle-vel-display => lowpass.spindle.out
and in pyvcp_options.hal:
replace
net spindle-vel-cmd-rpm-abs => pyvcp.spindle-speed
with
net spindle-vel-display => pyvcp.spindle-speed
net spindle-vel-fb-rpm <= hm2_5i25.0.encoder.04.velocity-rpm => abs.spindle.in
net spindle-vel-rpm-abs <= abs.spindle.out => lowpass.spindle.in
net spindle-vel-display => lowpass.spindle.out
and in pyvcp_options.hal:
replace
net spindle-vel-cmd-rpm-abs => pyvcp.spindle-speed
with
net spindle-vel-display => pyvcp.spindle-speed
