Where did you buy the Laser generator?

Br549-

Thanks for setting me straight.  I used your version of the G-code and everything is now working great. 

Les Sent me a modified POST program, now I can run a program without editing all the code.

Thanks for the help

Ger21 and BR549-

I started playing with the Macros, and I could get everything to work when I used 4 macros.

I used m801, 802, 901, 902.  I chose these numbers because I could test different codes, and still have my cutter running using M03 and M05.

Once I get everything figures out, then I will edit M03 and Mo5


ok Now for the problems

When I used simple 1 line commands everything works great
ActivateSignal (output2)

When I statrted doing multiple tasks is when I started having problems

code ("G31 z-100")
code ("g92 z-.08")
sleep (100)
ActivateSignal (output2)
sleep (100)
ActivateSignal (output3)
sleep (100)
deactivateSignal (output3)


the problem is that the solenoids turn on before the z axis reaches the correct height

I tried to use --

While IsMoving()

Sleep (100)

wend


but this command locked up the computer.  Is there something that is supposed to be inside the () like a 1 or 0?



Thanks for the help

Graham-

when you say that Mach searches for a known home position, is that the same as the reference position?

Hi all-

First I want to say that I know ZERO about G-code.  This is my first cnc project, so I am learning as I go.

I am using sheetcam, and this does just about everything I need, but I am wanting to make it better.

I have a cnc oxygen/ propane cutter nad here is what I am wanting to do

Here is the order of events
>
> 1. torch moves to cut position
> 2. z axis moves down to find the plate---at speed 75ipm G31 Z-75
   3. Z axis resets zero + needed offset G92 Z-.15
> 4. z axis moves UP to .140
> 5. output #2 turns on (this turns oxy/propane on)
 6. wait .1 or .2 seconds (this allows propane to get to torch)
7. turn on output #3 for  .2 seconds ( this turns on electronic torch igniter
>
> continue with the existing post processor
>
> 8. when cut is finished, raise Z axis to safe height and turn off
> output 2 (this turns off the solenoids for the pre heat oxygen and
> propane)
>
> 9 continue to the next cut cycle


so my main questions are

1.  how do I turn output #2 and 3 on and off
2.  How would I create a timer/ delay

Les with sheetcam is helping me create a POST that will do all the functions that I need, I just have to develope the g-code that I need


thanks for the help

Hood-

I installed everything, and for once I can not make the drives fault.  I will be cutting some plate this weekend, and it will get a good test.  I should know then how it works.

So are brains just ladder logic?  I have not looked at them until now.


Thanks again for all the help

I will keep you posted

Hood-

I am wanting to use port2 pin3 for the fault.  It can be any input number that you need to use.  To my knowledge, none have been used so far.

Thanks for all the help.

Hood-

I have been trying different ports and pins trying to get something to work.  I quess I did not re-enable input #1.  But I had it enabled during the weekend when I was trying to get it to work.

here is where I got the name and the port and pin location

This is the I/O card from candcnc.com

Hood-

I think this is the one I am using.

When I get to the house, I will post more information
