Carbide Motion/Fusion 360 part accuracy

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

As @mhotchin noted, if using a machine w/ belt-drive axes they will need to be calibrated for belt-stretch.

If you have a lead-screw or ball-screw axis, it should be very close if not dead-on.

Another consideration is tool deflection.

Naturally all of this assumes that the tool is correctly entered/selected and toolpaths are appropriate to the material/part.

I would suggest making a simple test part such as:

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]

in both Carbide Create and Fusion 360 and cutting it in a stable material such as MDF.

If both are wrong, then we can help you w/ the Carbide Create file, and that should provide insights to fixing the Fusion 360. If only the Fusion 360 file is off you’ll need to contact Autodesk.
