ReprapFirmware with 17 point bed levelling. Complete overkill

9 point bed levelling was not enough apparently. As the layer height decreases for better prints, the 9-point routine described before was not good enough. The next easiest and logical step was to increase it to 17 points. This method will immediately become obsolete once the final release v1.18.1 of David Crocker’s firmware comes out, […]

I needed more points to level the bed properly. I made the following changes to version 1.13 of David Crocker’s firmware to allow 9-point bed levelling, where the 9 points are arranged like this:

Below some printing temperatures that I found to work well with certain brands of filament.   RS Pro PETG white: 235C, 95C […]
