Remotely control Machine on button

Hi Again,

Perhaps I'm not stating my question correctly. Basically I don't want the LinuxCNC power button, so I'm trying to automate it. I want the power button to automatically change to reflect the e-stop status. By default Linux CNC turns the power button off when the machine e-stops. So when the machine comes out of e-stop I want to send a signal to automatically turn the LinuxCNC software power button on. Turning it Green and unlocking the controls. I don't want to rewire the machine to have a momentary button as Aciera suggests. and my stock HAL file already matches Norbert's post.

If I understand correctly (and I probably don't) the below line enables the machine when it comes out of estop
net estop-ext => iocontrol.0.emc-enable-in
So I want to enable the machine and turn on the power button so I want something like the below, but it does not work
net estop-ext => iocontrol.0.emc-enable-in => hal.ui.machine.on

I doubt there is anything relevant in my config, but it's available github.com/rogerfries/Boss5.git

This whole power button thing is really a minor annoyance, but I think Learning how to do this will be important to help me learn how HAL works for my future objectives. I want to add a bunch of buttons to make a control panel and a touch plate tool height setter.

Thanks

Roger

Bevins,

Thanks for pointing out my typo, but the root issue is there can only be one output. I get the error "halui.machine.on was already linked to signal estop.ext".

Thanks

Hi Bevins,

Thanks for the sample code! I tried the sample and I have an issue. I'm just not grasping HAL yet so I can't determine how to solve this. Any suggestions? Thanks!

I get the error:
./Boss5.hal:411: Pin 'estop-latch.0.reset' was already linked to signal 'estop-reset'
