Toolpath Trouble

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

If the distance the machine moves has changed, this is probably because the belt tension is different.

For calibrating it see:

Calibrating the machines over long distances

The typical technique for machine calibration: https://my.carbide3d.com/faq/belt-stretch/ 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: [ima…

You could apply that principle to adjust the current steps/mm so as to match the movement by the previous setup.
