Now there is one more thing I would need to add to my spindle section in hal,
and that is "Spindle at speed" future (machine waits for spindle to reach
rpm's).
I found this guide for implementing this:
http://linuxcnc.org/docs/html/examples/spindle.html (section 5 & 6.2)
As I have a bit different case (using sptepgen), I would need some help what
and where to use it.
Here is my section for running spindle:
loadrt scale count=1
setp scale.0.in 0
setp scale.0.gain 0.14
setp scale.0.offset 0
addf scale.0 servo-thread
setp stepgen.2.position-scale 1
setp stepgen.2.maxvel 18000
setp stepgen.2.steplen 1
setp stepgen.2.stepspace 0
setp stepgen.2.dirhold 20000
setp stepgen.2.dirsetup 20000
setp stepgen.2.maxaccel 100
# Enable
net spindle-enable <= motion.spindle-on => stepgen.2.enable
# Connect spindle speed to scaler
net spindle-cmd motion.spindle-speed-out => scale.0.in
# Connect scaler output to stepgen velocity
net spindle-freq <= scale.0.out => stepgen.2.velocity-cmd
# Connect output to the pin for the analog voltage of C6 board
net spindle-out <= stepgen.2.step => parport.0.pin-14-out
# Control of spindle on/off over the relay
net spindle-fwd motion.spindle-forward => parport.0.pin-16-out
Do I need to add another function for spindle-ramp or can I use
stepgen.2.maxaccel, where I already defined acceleration? If so, which lines
and connections I still need to use in my case then?
