I have a question on looping in Mach 3.
For example, I want to do looping 3 time of the following program:
G90 G1 X2.0 Y2.0 F400
G1 X0 Y0
How do I do it?
I try to use M47, M99 and L but they all don't work. They don't even appear in Mach3 when I load in.
Anybody please help how to do it. And how do M47, M99 and L work?
After you type M47 hit the enter key to put the cursor on the next blank line, and then save.
I`m not sure why Mach doesn`t show the last line of code but this method works for me. Sometimes I need a blank line on the top of the prog.
Can you please also help me with looping as well? If I want to do 3 times looping how do I code it? Only at M47 at the end will not stop, it will keep looping it.
line 1 - M98 calls sub-routine number 123 and L3 commands it to repeat 3 times.
line 2 - program stops after completing.
line 3 - O123 ( O=letter O not zero) 123 can be any number you chose as long as it`s the same as in the M98 line.
line 6 - program return.

Joey:
After lots of searching and reading I came across your old post. It's Nov 2016 now. It solved my problem and works great! Thank You!
One thing I found out that may help others, It won't work with my machine if I put line #'s in front of your lines, like "N204"
If I just copy and paste your code in to my G code it works great.

Know this is an old thread.
Am posting to help others with a related issue.
Have run into a situation in Mach3 where a loop will only run once, no matter what M98 L is set to.
(May also cause other issues in Mach3)
As Joey mentioned put a blank line at the beginning & end of your Mach3 G-code files.
Additional info: Put a "%" sign (without the quotes) by itself on the last line of the file.
This will allow your loop to run "L" number of times, instead of just once.
