Welcome to LinuxCNC.org

Yes, when I enter M141 in MDI, I want ladder to see that as an input, then perform some logic in ladder, then ladder fires the solenoid. Here are the files and code associated with my M141 command.

In my ng file

M141
#!/bin/sh
#low-speed
halcmd sets motion.mspindle-low-speed true
exit 0

In my hal file
newsig motion.mspindle-low-speed

In my postgui file

net M141 classicladder.0.in-26 <===motion.mspindle-low-speed
net low-range-sol classicladder.0.out-24 ===> hm2_5I23.0.7I71.3.output-02

Your trying to use a signal as a pin and that is not allowed. newsig is generally not used anymore as it has been replaced with net.

The following should work in your postgui file and should be all you need...

net motion.mspindle-low-speed => classicladder.0.in-26

Working good now.

Thanks
