What did I do wrong with my items?

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

Cutting deep slots is not a good approach to achieve accuracy, which is why the usual test has one removing pockets:

Diamond-Circle-Square Calibration file

The last one I posted: no longer opens properly in current versions of Carbide Create, so here is how to draw up and assign toolpaths to one. Begin by launching Carbide Create, going into Job Setup, and creating a 4" x 4" stock area with the origin set at the center: [image]

If the dimensions of that test don’t work out well with endmills which are verified as to dimension on a machine in good mechanical condition, then see:

Calibrating the machines over long distances

The typical technique for machine calibration: depends on precision measuring tools, and is limited by the reach of the tools in question. EDIT: It also depends on access to the MDI — if using Carbide Motion v6 it will be necessary to enable this in Settings | Options: [image] It should be possible to cut strips from a suitable blank of material, one along each axis — so we set up a square file which matches an available blank of material: [image] and put in suitable geometry and assig…
