    Is it possible to have the DXF of the bed, i mean the PCB? I am not so happy about sagging and the solutions I can come up with and I would like to get a 8mm MDF frame for under the *cork*. For that I need the DXF of he PCB.

    Thanks.

    I want to remove the sagging of the PCB. 5mm is minimum even if it still bends at high temps

    Maybe I am going to look for an carbon fiber sheet for under the PBC. Does not need to be that thick to be stiff enough...

    Damn IOS typo!!!!

    I use carbon fibre instead of glass on another printer. It bends a little bit. Same with 5mm MDF. Maybe the best solution is aluminium heater between the pcbs and the glass in order to spread better or a third arm int he centre (like a profile with insulant paper on top).

    Or replace the pcbs solution with a alluded with caption tape underneath and insulating corner pins instead of screws. All these are possible if we get the Dxf of the pcbs heater.

    @Spoon Unit I saw your solution. It is practical.
