| Can any one tell me what mean "Macro A" and "Macro B" |
| Omer, Macro A is an older style of programming which is not used much. This would be for comparing conditions thru the actual macro call. MacroB is to carry variables over thru a macro call and use conditions/statments like IF, WHILE, LE, GT to machine. Macro programming is very powerful and is probably one of the most underutilized type of programming but the most effective. It is very hard to sum up exactly how it works. Here is a very quick example. O0001(main program) G65P8000A5 M30 O8000(subprogram) IF[#1EQ5]GOTO200 G1X20. N200M30 Now in program 1 it will call program 8000 and it will also set #1=5 because A is for #1, B is for #2 etc. If you added a B50 into the G65 line then #2 would =50. Now in program 8000 it does a IF statement. That line asks IF #1 is equal to 5 (which it is) then go to N200. Which it would end the program and return to program 1. Now if #1 is not equal to 5. Say we set it to 2 then it would not go to 200 but it would run the next line of code which is G1X20. And then end the program at the N200. Stevo Stevo |
| "Macro programming"
Hi, I'm looking for more information on programming with macros. Are there any books or online resources available that anyone could suggest that could help me out. I'm a CNC operator going to school for CNC programming. The programmers at my job have given me a new program to run with macros and I want to learn more about them. They don't know anything about them as they had the program written by someeone from a different company. The program is not working correctly since the programmer is not at our facility. My programmers then have to go back in the office and call the other programmer who fixes one problem then my programmers come back out with the updated version. This whole process could be eliminated if I just could get a crash course on this style of programming and understand more about it. I've got an idea but some more information could be very helpful. |
