Hi, Jermaine RF

Have you checked with Delcam's Powermill 6 for a  "post" for Mach3.

Mach should respect G-code you create.

There are Tool and Wowk Offset Tables on the Offsets page.

I think the "Tornado" has been replaced with right side Pointer.

Hope this Helps, Chip

Hi, Jermaine RF

Post your G-code and XML file, You can add your B, C, Axises DRO's to show the Deg's on each.

Your xml is the profile you load when starting up Mach, If it's the default it will be Mach3Mill.XML, Located in C:\Mach3 folder.

Make a copy of it and rename it Jermaine.xml, Then you can post it. It needs a unique name to post it hear.

Thanks, Chip

Hi, Jermaine RF

1. It should.

2. It should

3. It's something that the g-code needs to specify, There are several setting options for rotational axises, But I don't think you can have limits set and have Mach disregard them on the fiy.

4, 4a. Depending on what your going to do/make, Probably need to generate xyz code and edit in the B/C g-code by hand, There are some 5 / 6 axis cam/cad packages out there I'd think, High End Software.

No experience with any of them hear, Others may comment at some point.

Thanks, Chip

Normally on 5 axis mould and die work where the B and C axis are on a swivel head, you are in effect cutting with a ball on the end of a stick,  this is set in the machine at a known distance from the centre of rotation for both the B and C axis.

This information is then given to the 5 axis CAM software where it can plot movement based on this. 

On a machine with a moving table the same method can be used, the difference is in the CAM software setup.

When you are doing surfaces the CAM software should take care of everything, if you are drilling and tapping holes in different faces then you can program the machine as you would a 3 axis.
