Need Help Creating a Grid File

[WillAdams (William Adams (Carbide 3D))]

I wrote up a bit about measuring the machine at:

Notes on rapid positions and wasteboard leveling

Finally taking the time to revisit this with other machine sizes. For a Shapeoko 3 the rapid coordinate positions are (assuming one has set the origin at the SW rapid position point): NW = 0, 350 N = 200, 350 NE = 400, 350 W = 0, 215 C = 200, 215 E = 400, 215 SW = 0,0 S = 200, 0 SE = 400, 0 which yields: [image] It is possible to move 5mm to the left along X on a Z-Plus machine, and 65mm towards the front of the machine, and the Southernmost Rapid Position Points are align…

You have a couple of options on the grid:

• draw lines which you then follow w/ a suitable endmill
• draw up rectangles which will allow V carving the design

If you get stuck, let us know what size machine you have and post the file and note the specifics of your difficulty and we’ll do our best to assist.
