very basic question, rhino visual mill mach 3 units
« on: April 04, 2014, 02:07:44 PM »
Hi all
can someone help me with this, I have a cad model in rhino, simple flat surface with a profile as a curve in x and y, I import the surface and curve into visual mill as an .igs file, chain the curve, then use the curve machining option generate  cutter path g code in visual mill, save as a .txt file, then import into mach 3.
the cad model is in mm, when I open up mach 3, it runs the cutter path ( x y z router) in mm but the units showing the progress are in inches on the programme run screen. The distances moved are in mm and it cuts the correct path. when I go to settings and change the units to mm, they go to mm on the programme run screen in the x, y z boxes, and I can jog the router in mm, and it moves in mm. but when I then run the g-code again, it jumps back to showing movement in inches, but still moves the correct amount in mm.

It makes setting the z height very annoying, as it keeps jumping back to inches, and if you are not careful you jog it in inches, when you think it is moving in mm, and crash onto the jig.

what I am missing? why is everything not in mm?
Probably a really basic question, but struggling to figure it out.

thanks

tom
