Plugin or upgrade Request - bad spots on Bed

[Scotty-G 1]

Best to start with - I am not a programmer.

Am wondering if it is possible in a future upgrade or as a Plugin, have a method to overlay a graphic or photo of our print bed so we can identify areas of our print bed that have damage.

My print bed has a few damaged spots - PEI film has broken off or there are large air bubbles under the PEI film that cause local extrusion fails but the rest of the bed is usable. Most of my prints can fit on the print bed with proper placement and I want to avoid those bad spots. If there is an easier way to identify them automatically on the print bed, would make object placement easier. I know that there is a grid that I can count squares but that gets tedious and cross eyed. I replaced the bed recently,  printed with TPU and forgot to put down glue stick so I have a small broken area.

 

Anyone wanting to tackle this and make a plugin or consider for an upgrade?

 

Thank you

Did you ever find a solution for this?

I had one test print fuse with the bed and I tore out a 20x40 chunk out of it.

I've been moving my models around in Cura to avoid the hole, but it'd be wonderful if I could designate that area as "off-limits."

This is there. You may want to look for/add "nozzle_disallowed_areas" in your printer definition file.

nozzle_disallowed_areas starts at center of the bed ([0,0]), defined by an rectangle  with x/y coordinates of 4 point's: [[x,y],[x,y],[x,y],[x,y]]

Example:

        "nozzle_disallowed_areas": {
            "default_value":[
                [
                    [10, 150], [10, -150], [-10, -150], [-10, 150]
                ]
            ]
        },

This will create a non printable area of 20x300 from front to back in the middle of the bed:
