I’m using smoothieboard in my 3D Printer (Delta) and my MPCNC.

In both case, I’m using Z-Probe. Mechanical switch on the 3D Printer and cooper plate with a lead connected to the bit on the CNC.

On the 3D Printer, I can calibrate the bed automatically, but on the CNC I can only find the Z-Height at one point.

I was wondering if I could do auto “bed” leveling. Piece of wood are not always flat, the wasteboard is not always flat and the frame is not straight.

Like probing to the 4 corner and maybe 1 or 2 in the middle to make smoothie compensate the g-code?

I think the idea with a wasteboard is that you mill it flat using the cnc router.

yeah, it’s what I do… but it take time and you have to redo it from time to time, plus, it doesn’t help if the wood on top is not straight and you don’t want to surface it. But as now, it’s my only options.

@Sebastien_Plante Use BCNC https://github.com/vlachoudis/bCNC/wiki

You can use BCNC, or use Gcodes to run grid levelling on a specific area.
