Welcome to LinuxCNC.org

Hi ,
ok newbies have to start somewhere , but becoming stuck on configuration using stepconf wizard . no doubt now begins a steep learning curve with emc ! , my parallel port is configured as

pin2 x axis step
pin3 x axis direction
pin4 z axis step
pin5 z axis direction

pin7 spindle step
pin8 spindle direction
pin9 spindle enable

pin10 limit sw x
pin11 spindle index pulse
pin12 limit z
pin13 Estop

pin 14 spindle on
pin16 spindle reverse


this works perfectly well under turbocnc , but i am having problems being unable to configure the spindle both in step direction enable signals & incorporating spindle on and reverse
also emc errors out on making pin 14 spindle on . saying that another pin is spindle enable etc , which i presume is pin 9

could someone be kind enough to show how to set the spindle correctly etc
i would like to lock the spindle from being enabled on by mistake , which is why i am using the spindle step direction signals ( from a homman digispeed controller to vfd )
but open to options

Thanks
Dave

I don't see a spindle enable as one of the choices. What are you doing to create it?

Thanks John for getting back , at the moment setting spindle as pwm give me errors see attached file , and their seems to be no way of setting step direction enable signals either for spindle use

net spindle-cmd <= motion.spindle-speed-out => pwmgen.0.value
net spindle-enable <= motion.spindle-on => pwmgen.0.enable
net spindle-pwm <= pwmgen.0.pwm
setp pwmgen.0.pwm-freq 50.0
setp pwmgen.0.scale 2666.66666667
setp pwmgen.0.offset 0.2
setp pwmgen.0.dither-pwm true
net spindle-on <= motion.spindle-on
net spindle-ccw <= motion.spindle-reverse

net spindle-pwm => parport.0.pin-01-out

net spindle-on => parport.0.pin-14-out
net spindle-ccw => parport.0.pin-16-out This attachment is hidden for guests. Please log in or register to see it.

pin 14 spindle on seems to be the problem pin , changing from spindle on to say spindle cw , clears the error , although of course this is not a cure

i presume because pwm is selected it is linked to spindle enable , although i would have thought having a specific spindle on condition , is a much safer option than a zero pwm value

From your debug file:
my-mill.hal:29: Pin 'motion.spindle-on' was already linked to signal 'spindle-enable'

The problem is that you are trying to link the motion.spindle-on signal twice. You can only mention each pin once in a HAL file, though you can use signal names multiple times. (the signal name is the first thing after the net command, and you can choose them freely)

(Or, to be even more compact, you could replace all 3 of the lines I quoted with:(As a net command must have a signal name, can have only one "source" pin but can have any number of "sink" pins.)

Thanks for the clarification , much appricated ... i 'll take that as lesson one ! in the long book of answers

This should jump start your HAL knowledge :

Glad to see you got it sorted out.
