is it's possible to program a external cycle start in mach4 

short n sweet. Yes, using the input signals from your bob.

its in the Mach4 scripting manual under manuals on the mach web site

Thank you, it's working

This may sound funny, but can you put the code on this thread? When I copy and paste from the .pdf my application puts in lots of line breaks and funny stuff. I don't know if everyone has this problem.

Thanks,
Peter

it looks like this





local inst = mc.mcGetInstance();

if (sig == mc.OSIG_MACHINE_ENABLED) then
    machEnabled = state;
end

if (sig == mc.ISIG_INPUT1) and (state == 1) then
local inst = mc.mcGetInstance()
mc.mcCntlCycleStart(inst)
end


local inst = mc.mcGetInstance();


if (sig == mc.ISIG_INPUT6) and (state == 1) then
local inst = mc.mcGetInstance()
mc.mcCntlCycleStop(inst)
end

and it has to go in to the "signal script"

Works - yeaaaaaa. I had to map my Input B on smartBob to input 1 on Mach4.

Dose this script also allow me to program a feed hold on Input 6?

Thanks,
Peter

yes  what ever you wont you could have it do, it`s just scripting needed if you get the M4 scripting manual it has how to do tables in it

Yep - the Pause or Feedhold works on Input 6.
