IF your system does NOT use an ARC OK signal then you may have to add more dwell time before the RUN signal is given . That will give the machine time to get the torch fired and steady BEFORE movement occurrs

DoOemButton(156)                      'Run SET NEXT LINE
Sleep(100)
DOSPINCW      'Refire Torch
Sleep(1000)      'ADD MORE TIME HERE
DoButton(0)       'Resume Program from Stop Point
End   


AS to the feedrate?  Are you using feedrate override?? IF so then the stop command may cancel out the FRO.  The macro copies the Current Feedrate then just applies it back so the values should remain the same.

OK this is the first macro that stops the machine and gathers data to return.     You may have to modify it to soot your machine and process

***********************************************************
'F13     Feedhold/stop to check torch

DoButton(1)                 'Feedhold
While IsMoving      'Wait for movement to stop
Sleep(100)
Wend
DoSpinStop                                 ' Turn OFF torch
Sleep(100)
SetVar(601,Getdro(2))     'Setvar to Zpos
Sleep(100)
DoButton(3)      'Set Stop
Sleep(100)
DoOemButton(104)      'Move to SafeZ
While IsMoving()      
Sleep(100)
Wend
SetVar(602,GetDro(0))   'Setvar to Xpos
SetVar(603,GetDro(1))   'SetVar to ypos
SetVar(604,GetDro(18))   'SetVar to Feedrate
SetVar(605,GetDro(16))   'SetVar to CurrentLine#
End

This is the second macro that returns the machine to work. You may have to modify it to soot your machine or process

**************************************************************

'F14
DoOemButton(104)                'Go To SafeZ
While IsMoving()
Sleep(100)
Wend
Code"G0 X#602 Y#603"   'Return To Stop Point
While IsMoving()
Sleep(100)
Wend
Code"G28.1 Z0.500"    'ReREF Head  to TOM
While Ismoving()
Sleep(100)
Wend
Code"G92 Z0.000"                    'Reset Dro
sleep(100)
Code"G0 Z#601"      'Return Z to stop Point
While IsMoving()
Sleep(100)
Wend
SetDro(16,Getvar(605))   'Reset SET NEXT LINE #
Sleep(100)
SetDro(18,GetVar(604))   'Reset Feedrate
Sleep(100)
DoOemButton(156)                      'Run SET NEXT LINE
Sleep(100)
DOSPINCW      'Refire Torch
Sleep(100)
DoButton(0)       'Resume Program from Stop Point
End   


Hope it helps

It depends on how you have mach setup as to how it reacts to stop.

BUT even with that jet cutting is very basic 2d cutting rarely would you see anything other than basic lines and arcs. SO that being you can restart anywhere without having to parse throught the entire program to get all the proper modes reset(run from Here).

You can simply restart with set next line fire the torch and run.

I will dig out the code for restart. It is a 2 part process  one button to stop thye machine safely saveing all the important info to variables. Then a another button to return to the restart point , fire the torch and restart 1 line previous to the original startpoint.

This gives you a point between buttons that you can correct the torch problem.

Just a thought, (;-) TP

To properly maintain position on the table you would do

Feedhold (until motion stops)
Stop

This allows Mach to come to a controlled stop witout LOOSING position.

Then you can do what ever you need to do to fixe the problem.

Then you can move back into position at a start point ahead of where you had a problem then use Set Next Line and RUN.

We have a special macro we run called restart that does all of this automatically so IF there is a cutting problem it is easy to remedy.

That way we don't have to rely on reverse run.

Hope that helps, (;-) TP

HI Steve,

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)




FIRST we need to clean up your code a bit. You do not use the () around the code statement it will cancell the statement.

Next we need to add in the wait while moving states to allow mach time to get to position.

code "G31 z-100"
While IsMoving()
Sleep(1000)
Wend
code "g92 z-.08"
Sleep (200)
ActivateSignal (output2)
Sleep (100)
ActivateSignal (output3)
Sleep (100)
DeactivateSignal (output3)

I would try the simple G81 drill cycle.

Look it up in the mach manual. Once called all you do is add the dril points. Then when done cancel with G80.

Hope that helps

I would use the existing m3 to turn on the torch and the M5 to turn OFF the torch. This will keep it simple AND allow you to simply modify the M3/M5 macros.

The delays can be setup in the M3 macro code it would be something like:

ActivateSignal(2)
Sleep(200)
ActivateSignal(3)
Sleep(200)
Deactivatesignal(3)

Let LESS at SCam know to  basically use the same post as the MP3000 plasma unit. It uses the G31 to find the top of material and turns on the torch with M3 and OFF with M5

Then modify your M3 and M5 as above.

When you get to that point lets us know if you need help.

Hope that helps

Sorry but to my knowledge there is NO solution for Jet cutting using rev run. The only solution is to feedhold, stop then reset the last section to recut  and restart the cut.

The fix would have to be done at the CORE LEVEL in mach.

TO answer your original question(;-)

OEMLED(108) is used to indicate if G68 is active or not.
