Wait for signal

(1/5) > >>

Evangelosemm:
Hello forum.
Can you please advice me how can i write the g code so when i get a high signal in to an input to stop the g code from running and when the signal gets low the program to continue running automatic.
Thank you
Evangelos

Hi,
Gcode as used by mach3 or Mach4Hobby does not include conditional statements. Without a conditional you cannot write
Gcode  to do it. Mach4Industrial enacts Marco B programming which does have conditionals and could do it in Gcode alone.

What you require is a macro running in the background that causes a <feedhold> when low and a <cyclestart> when high.

I use Mach4 and would code this in Lua easily enough. I presume you could do a similar thing in Mach3 but I can't be bothered
with Cypress Enable.

Evangelosemm:
Thank you very much for your answer. So I need mach 4 indutrial in order to be able to get signals and manipulate the g code. I am new to all this and I don't know if there is a manual for m conditional Instructions and how to do it.
I ll do a research and if cant do it maybe ask you again. Thank you in deed.

i am not familar with Mach4 (LUA Scripting),

but i am pretty sure that the is (Mach4Hobby), a posibility to create a macro call M123 or what ever,
witch is waiting for a stupit Input to get "High".

Evangelosemm:
Is there any manual for M commands at Mach 4? Is it possible an example? A small one from point a to point b with a wait at point b.
Thank you
