G-Code, CAD, and CAM discussions / Re: Newbie question on G-code looping (While, for, etc.)

« on: March 21, 2010, 06:34:36 PM »

The only way to do loops at the moment is by using subs or VB macros

You can use # vars and operators but no IF's or WHILE, GOTO's or conditions LE, etc.

Search the forum for M98 and you will find lots of examples to do loops and conditions.

If Mach has no known home position it can not work to absolute values so it reverts to incremental values in G53

Mach3 Version 4 is much more compliant with the standard, but in saying that not many modern CNC controls follow the standard to the letter, Mach3 will be the same, there are enhancements and omissions and as such running any code created for any other G-code control must be run with care.

G28 X0 Y0 Z0 will send the machine to a known home position, e.g. you have homed the machine manually.

G28.1 X0 Y0 Z0 will search for the home position.

G28 X5. will go to home via the position X5. ( used to avoid obstructions and the like )

you need to do a feed/lead out line into open space within your rectangle.

Search the forum and manual for lead in and/or lead out
