General Mach Discussion / Re: Assigning a port/pin to "torch up/torch down"

I appreciate your help guys. I found out the air valve is junk so ill have to wire it to an LED to get it "working" for now.

The Y axis travels towards the home/limit switch.

It homes, but because its homed onto the limit switch, it resets and generates a limit switch error. I then go into ports and pins and disable the limit so i can jog off.  We build press brakes here, and when we calibrate our backgauges, it will home then come forward about an inch automatically and the home switch acts as a limit.  If the axis homes and sits on the switch, the limit is triggered.

When i tried this, the axis will home. Then it says "cannot jog when limit switch is active" and i have to disable the limit to jog off.

General Mach Discussion / Can Home Switch be -- limit switch...

Im currently setting up my limits, the previous control on the machine im retrofitting ran a single limit switch at each end of the machine travel. If i assign the same limit switch input to the Y home and to the Y--, when i home, the machine will shut down. I can run the machine with just a Y++ limit switch and make sure the soft limits are on, but if they're not on, you can crash the head at the Y-- limit.

Do I have to run a separate home switch from my limit or is there a way around? Say, the machine homes, then comes .5" off the home switch and once its homed it treats the switch as a limit?

The spindle relay needs to initiate 2 functions though. First a signal to lower the torch, then to start the torch with a pause in between.

Thank you. I didnt understand that you could put G codes right into the script editor thought G4 was something else.

Do you have a link for coding basics or something? I have no experience what-so-ever.

I assume "Code G4 P5" is a code to initiate a 5 second delay?

Hmmmm. not sure why this is not working right.

If run through the script window, it's fine.
MDI M3 and the spindle starts imediately.

Hmmmmm, prety sure this would work in earlier revs. 

RC 

BOTH of these work through the scripter window, but w/MDI, OUT3 never comes ON and the Spin. starts and stops immediately.
Otherwise    I think it is what you are looking for.

I need a Code Monkey,
RC

So what you have there "activate signal(output3)"

Would initial output 3 upon an M3 signal?  So you make the macro for M5 read "deactivate signal(output3)"?

Also, my output signal to my plasma unit will be "spindle on" and "off"?

When you run a program, the torch turns on and off each time it cuts a shape from your plate. You want the torch to lower to each cut, then raise up and move to the next cut. So basically when the torch is off, you want it up, when the torch is on you want it down. But you want it to drop down a second before the torch comes on, and you want it to go up a second after it goes off. The function is to protect the torch tip from intersecting with parts you've cut that have shifted after being freed from your stock.  Right now i could manually add code throughout the G-code and assign "coolant on/off" to my height control, but that isnt ideal because i can't generate that into my code. 

If i could make the delay from "torch on" into movement, i could just use the torch on function. I just need to know how to assign a digital output to "torch on".
