Rapid positions incorrect after pully & belt change

[metalbender (Scott Noble)]

on my Shapeoko 3. Finished install new v pullies, new belts. Didn’t disturb any wires. Initialize went normal. Jogs normal. It will zero XYZ without a problem. Haven’t run a file just yet but… 6 of the 9 Rapid Postions have moved, 3 off the front of the machine.

W(west, C(center), E(east) have all shifted to front of the machine. SW, S, SE have all shifted OFF the front of the machine causing sever crashing. NW, N, NE are normal. Full disclosure, I don’t use rapid positions, but lets be honest this isn’t good.

Calibrate for belt stretch:

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…

Thanks Will. I’m saying for instance when I’m at the North Rapid Position and select the Center, the machine bypasses Center and stops at the South Position. The machine won’t go to West/Center/East.

Check microsteppinh and which machine you configured for.

Must have had the configuration set to XXL. Changed to XL. Rapid Positions all restored now. Thanks Will…

This is a pretty basic question, but - could you have gotten the wrong maintenance kit? The S4 kit has larger pullies, which is consistent with the behaviour you are seeing.

EDIT - nevermind, the problem was something else.
