First test job running perfect "except" it's half the proper size

Software Carbide Motion

As stated above, the job is running as expected except the size is slightly less than half size. Drawing is in inches, 8x6 inches. Shapeoko 3 is cutting 3 7/8in by 2 7/8in. Google search indicated some docs but a search does not find them.

Is this a known anomaly and what’s the proper solution?

Thanks,

Alan

I suspect you have a board configured for 8x micro-stepping and are using the old defaults for 4x micro-stepping. Please see: http://docs.carbide3d.com/shapeoko-faq/how-to-calibrate-the-machine-for-belt-stretch/

You need to go into the MDI after connecting to the machine and change $100, 101, and 102 to 40 (I believe that at this time they are set to 20).

You can verify the defaults against: http://docs.carbide3d.com/software-faq/shapeoko-3-default-grbl-settings/ and configure homing if you have it per: http://docs.carbide3d.com/shapeoko-faq/shapeoko-enable-homing/
