Shapeoko 4 Pro XXL - E steps

[dpcrawford50 (Dan)]

I searched around and saw nothing about this.

I understand how to set e-steps in all axes. It is not a huge deal, but I would like to see a semi-automatic procedure of doing this.

What I mean is, I mark a point with x=0.5,y=0.5 and x=20.5, y=20.5 manually on my spoilboard. From set 0,0 I move the spindle to those physical locations. The software asks me to enter the anticipated coordinate at both points while physically set over them. The software calculates the e-steps based on its location vs what I told it that it should be.

Maybe I am asking too much.

Do you wish to calibrate for belt stretch?

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…

The software calculates the e-steps based on its location vs what I told it that it should be.

You’d have to enter the actual location, though. As far as the CNC knows, it is where it was told to go.

You could do a semi automatic version with a piece of accurate stock and a probing routine through macros.
