The standard Z-axis on a Shapeoko 4 is a Z-Plus which has a leadscrew.

The optional HDZ Z-axis has a ball-screw.

The default steps/mm for the belts have been 1/40 mm for a very long while, and it’s unlikely they’d be off that much — the adjustments indicated by techniques such as:

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…
