trouble getting hal_hscale1 value in py handler

spindle(SPINDLE_FORWARD) ...

but I have yet to find how to set the speed. is there a way or do I need to

halcomp[motion.spindle-speed-out] = my_speed_value

which also I have not figured out how to make work

Not sure if your using 2.5.3 or master.
If using master you can set the RPM within linuxcnc.command

self.linuxcnc.command.spindle(direction, rpm);

direction would be 0, 1 or -1

more stuff I forgot to tell.

I am using 2.5.3

Humm,
another way to look at this is our spindle is controlled directly via a hal signal linked off the spindle-cmd and spindle-enable pins.
in our hal file we have:
# spindle on / off
net spindle-enable <= motion.spindle-on => ourbox.0.pin-25-out
# spindle speed control
net conv1 conv-float-u32.0.in motion.spindle-speed-out
net c-spindle-cmd <= conv-float-u32.0.out => ourbox.0.spindle-speed-out

So our spindle-speed-out accepts values from 0 to 20000. The issue we have here is that the spindle will not start until we have a minimum value of 5000.
Now we are trying to creating our own glade spindle button much like that of Axis, because when we click the axis spindle start button we need to click the '+' button at least 50 times... haha!

It would seem a trivial task to make a python interface layer to set out spindle speed out to 5k to 20k via our slider to turn on our spindle. If we go the MDI route axis complains the machine must be in MDI mode to turn on / off the spindle and looks kinda clunky. Perhaps not.

Maybe there is an easier work around to better configure the axis buttons?
(This solution is not ideal however because we have the same issue for hot wire control, only in this case the axis button does not exist)

Can anyone point me in a direction to see an example where a hal float style pin is set to a given vale or changed through python? is this even possible?

Hi

can you please share your code on getting the hscale value. I have the same problem.
