Br549-

 I am starting to understanding of what I am trying to do.

I have a few questions:

1.  What is a Scam post?
2  What is a Macropump?

Is there are range of variables that I should use, or a range of variables I need to stay away from?

that is a good idea about pierce count.


thanks for all the help


Steve

about Scam post : in folder post in sheetcam ,there are many file that constructive Gcode with our custom settings.
about macropump: When we want something check constantly we can use this function.

The Scam(SheetCam) post is the part of Scam that actually writes the Gcode based on the drawing and other parameters. Less will handle the modifications of that part for you.

A Macropump is a piece of code that mach runs continuesly. I t can be used for uses such as this.

You can use any Gcode Var # and you will only use 1 AND you have to let LES know which one you choose.  I would use one in the range of 500-600 as those Vars are stored in MachsXML file when it shuts down and will always be there at startup. The other #Vars are not retained when Mach shuts down.

Also you can set the dro to be stored as well so you have double safe values on startup(;-)

Hope that helps, if not we will try again(;-)

Thanks for the information.  It does not look like it should be that hard to accomplish what I am trying to do.  Now to find some extra time.  I don't think I am going to make it to the shop until this weekend.  Work has picked up, I guess that is a good thing.

i think this Thread is forgotten.
please describe a practical example.

OK-

I finally have time to work on this project again!!

Everything is kinda working, and I am trying to track down where the problem is.

The sheetcam POST has been modified so that it uses variable #500 to determine preheat time for the Oxy fuel torch.

The problem is that the only way I can change the variable is to edit the g-code. 

There is a line towards the top that sets the variable to what the tool setpoint is in sheetcam.

the line is

N********* P#500=20

so if i edit this line then I can change the preheat time through the g-code.

I tried to change the #500 variable using the MDI and it did not change anything.

I entered this in the MDI      VAR #500=10

the problem is that I am not sure if the variable changed.


So here is what I think I need for now

a small window that has the actual value of variable 500
and a up and a down arrow, that when clicked on will either add or subtract 1 sec to the variable #500
then display the new value of the Variable #500 in the window.


How would I go about this?


thanks for the help



Steve

from the MDI line type            #500=20       then press enter


To make it seemless you need to install a OEMDRO on the screen, then add an update button beside it.

Add code to the button to update the var based on the OemDro

SetVar(500,Getoemdro(*********))      where ********* is the OEMDRO# you used. This way whenever you want to update the preheat number just input the new value then press update.

OOPS message timed out,eating supper(;-)



Add an OemDro to the screen. Then add a Raise and Lower button to the side.


To the Macropump add the following code, This will update the OemDro with the Var500 value UNLESS it is a negative number then it sets Zero

If GetOemDro(***) < 0 Then SetOemDro(500,0)       ' Where *** is the OemDro Number
Else
SetOemdro(***,GetVar(500))
End If


Next add some button code to the up and down buttons

Up

SetVar(500,(GetVar(500)+1))

Down

SetVar(500,(Getvar(500) -1))



That should about do it, If you need more help just holler

I will try that first thing in the morning.  It is too late to go to the shop tonight



Steve

Steve did you get your Scam post sorted out? I saw where you did not have the OnToolChange() included in the post so the Var value was never included in the output.

BR549-

My wife made me mow the fields.    but there is always tomorrow

I should make it to the shop in the morning.  I should have 4-5 hours before I goto work, so I will let you know how it turns out.


Thanks again
