Simple macro question

[Azalin]

Hi,

I'm opening this thread for a friend and I'll try to ask it as simple as I can.

He'll put a line somewhere in the code (let's say M900). He wants Mach3 to pause the code at the line where the M900 is and wait for the operator to trigger a hardware switch then continue executing the program from there. Please see the very simple gcode bellow.

M200
M202
G01 X-40 F50000

G01 X40 F85000

M900 -----------------------------------------> This is where the code waits for the switch input.

Is there a sample macro to play around to achieve what he wants?

Thanks in advance,

Just use M1 and turn on Optional M1 Stop.

Hi again,

I think I misunderstand his question.

Say, he has a hardware switch (connected to somewhere in the BOB). So the new question is as follows:

- He starts a program (gcode runs).
- If he did not pushed that switch the program will stop at the M900 (or whatever) line. Programs waits for the switch input. He pushes the switch and program runs trough that point.
- If he already pushed the switch even before the code hasn't got to the M900 line then Mach3 will skip the M900 and keep running.

I really don't know why he need such operation but anyway. Any helpe would be apreciated.

Best,
Suat
