I set up my RhinoCAD profiling model in mm and posted it to Mach via RhinoCAM.

The resultant G codes are always in inches. ie G20 not G21

I am nearly done coding in VBA to effect the conversion of the lines of G code to mm but want to know how I can set RhinoCAM to post process in the native unit - mm- of my models.

Any help please?

From memory it is done in the Post Processor. When you edit the processor these is a box to tick. If you cannot find it I'll go look

Thanks bud. But can you be a little more specific please?

I visited K2CNC's site and there are some links there that are supposed to help. k2cnc.com/Mach2_Mach3_setup.asp

It did not work for me. I will also look at this later in the day.

In RHINOCAM Browser click setup TAB, click the hammer spanner icon select Post Processor Generator, Click on MACH2, Edit. Under general tab select "mm"

I really thank you. It was really quite easy and very helpful.
