Add variables for bed area used.... To drive new adaptive bed mesh capability in klipper

[PhilBaz]

Is your feature request related to a problem?

Yes, in a sense. Useful variable data is absent from the current code.

Describe the solution you'd like

To have the required data to drive adaptive bed mesh native in Cura.

The Issue:

From: https://github.com/Frix-x/klipper-voron-V2/blob/main/macros/probing/bed_mesh.cfg

Cura is a bit more tricky as you need to install the post process plugin by frankbags called MeshPrintSize.py. In Cura menu, click Help > Show configuration folder. Copy the python script from the following link into the plugins folder: https://gist.github.com/frankbags/c85d37d9faff7bce67b6d18ec4e716ff#file-meshprintsize-py Then restart Cura and select in the menu: Extensions > Post processing > select Mesh Print Size PRINT_START [all your shit..] SIZE=%MINX%%MINY%%MAXX%_%MAXY%

The current solution - python script.

        "settings":{}
    }"""

def execute(self, data):
        minMaxXY = {'MINX':0,'MINY':0,'MAXX':0,'MAXY':0}
        lineData = ''

        for layer_number, layer in enumerate(data):
            for k,v in minMaxXY.items():
                result = re.search(str(k)+":(\d*\.?\d*)",layer)
                if result is not None:
                    minMaxXY[k] = result.group(1)

            areaStartGcode = re.search(".*%(MINX|MAXX|MINY|MAXY)%.*",layer)

            if areaStartGcode is not None:
                if not lineData:
                    lineData = layer
                for k, v in minMaxXY.items():    
                    pattern3 = re.compile('%' + k + '%')
                    lineData = re.sub(pattern3, v, lineData)
                
                data[layer_number] = lineData
    
                                     
        return data

Describe alternatives you've considered

the current python script.

Affected users and/or printers

Adapitve bed mesh should become the new norm. So more and more people.

Has there been any progress on this? Is there a variable for first layer area in Cura?

@parkernilson My advice to you is to try Orca slicer.
