General Mach Discussion / Machine set to millimeters can I use gcode with inches OK
« on: July 19, 2012, 01:53:52 AM »
Hi
This is my first post and I fairly new to CNC so it may be a dumb question.
I've built a CNC hot wire foam cutter for building RC wings and fuselages and I've set up MACH3 units to be in millimeters. I run some test cuts on some small wing profiles and everything is good. So now I want to cut a wing to actually for flying with. I'm using Profili2 to design the wing and generate the gcode. I'm using a old plan in inches and have created the gcode OK.
I now there is a gcode to specify inches or millimeters so even though I set my machine up to use millimeters if the gcode says inches at the start will it do the conversion or do I need to convert it all first.
My machine build and a video of it working can be seen at http://www.rckeith.co.uk/cncfc.html
