G-Code, CAD, and CAM discussions / Re: real meaning of G28 ?

« on: March 18, 2010, 03:50:28 PM »

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

Are you in table view?

Try toggling the table view button.

Are you running the DEMO version?

When Mach3 draws the tool path the feed lines are in blue and the rapid lines are in red.

If you double click the display the zoom is reset, left click rotates and right click pans the image.

That is correct, when you specify the tool in MC you will need to also specify the offset to use, it may be in the tool library or you may need to adjust it as you pick the tool.

Hi,

its not a mach3 problem, you need to edit the post processor to resolve this issue, if you search the web you will find modified versions of the mach3 mastercam post.

You need something like this in your M3 macro

If IsActive(INPUT3) then
  Dospincw()
End If

General Mach Discussion / Re: G52 use and problems with toolpath on subsequent parts

« on: March 08, 2010, 07:14:56 AM »

The only thing that I can see in the previous code is that the G52 should be cancelled (G52 X0) before the next one is commanded.
