Need Help!- Is M8 common Code for coolant?

[SpeedsCustom]

Hello, I'm running a Taig cnc using EMC2. I'm in the process of install my new BOB from cnc4pc, a multifunction board that will control everything. As far as I'm concerned, I think too run my coolant after it's hooked up too my BOB is in each of my files, too place the command for turning coolant on and off.

Is m8 correct coding that will work with EMC2 for coolant or is there something I'm missing?

Please let me know.

Not sure about EMC, but M7 is usually mist coolant, M8 is flood coolant.

Ok, Just making sure. I thought it was M8.

If you're running the typical ubuntu install this is easy to find.

applications > cnc > g code quick reference

should open up in the web browser

M8 is commonly Coolant on, M9 coolant off, but it is what ever the MTB makes it.

Did some tests. EMC skips m8 and m9 in my file allowing no coolant too turn on or off? What the heck? Coolant is designate too Pin 1 and Pin 1 works because when I set it as E-Stop, and enable/disabled it, the coolant turned on and off.

How is your hal file setup?

should have 2 lines similar to this
net coolant-flood <= iocontrol.0.coolant-flood
net coolant-flood => parport.0.pin-01-out

I need too access my Hal, but saying this like a Noobie, I have never really got into it and changed anything. How too I view my Hal file.

Same as any other text file, a gui for this is still in development unless I'm behind the times.

I'm still using hand written configs so take the following fwiw. Look in the emc2/configs/ for the directory created by created by stepconf. In my-mill.ini (if you went with the default name) 2 HALFILES are called, my-mill.hal and custom.hal. According to the readme, custom.hal is for user created commands to prevent stepconf from overwriting. Watch out for conflicts.

Hope this helps in some way.

I'm not sure whats going on. Sorry, was away enjoying the Epic snow of Jackson Hole Wy last week. Anyway, I have gone into Spetconf many times, but I must be skipping something. I still have not figured out why EMC won't read the M8 M9 command.

Too Samco, I do not know how too access what you showed ....Noobie here with EMC.

Under the Stepconfig wizard did you try and invert the signal. Its a little check box next to the Pin setup. I want to say its on the second screen before you get the x axis. If I remember correctly it will take it from 0v to 5v. Im learning myself so take the advice with grain of salt.

[SpeedsCustom]

No, when I invert it. It will automatically go on and stay on when EMC is open, it's not reading the M8 / M9 coding.

UGH....
