That part is now solved, now the next
./GB_2speed.hal:490: Pin 'GB-2speed.0.motor-speed-in' does not exist
Shutting down and cleaning up LinuxCNC...
# ---Setup spindle at speed signals via GB-2speed.comp---

So I now get a message that shows what gear to use.
Testing with 80rpm and motor starts but at very very low speed (spins as if there is no gearbox
)
Trying other speeeds = No Go
So how to solve this so the motor spins at low or high speed? In this case Lo speed (1400rpm on motor shaft to gearbox)
Any-ways this is going in the right direction, looking forward to get this running.
Cheers

Here the lines in hal for spindle, hoping this can be sorted out to have *full speed* instead of low rpm output.

Hmmm just pondering
net spindle-vel-cmd-rpm-abs
is above lines command to be changed to
net spindle-vel-cmd-rpm

At commanded S80 the frequency out from VFD should be about 32Hz and not as in picture 1.84Hz
50Hz / 125 (max speed in that gear) * 80 = 32Hz
So something is missing, scaling or ratio perhaps in comp or hal?
