In the UI, add text to clearly indicate that the temperature that the user must enter is for the bed, not the nozzle, the note informing the user states that the temperature relates to the material being printed. This is misleading as it gives the impression that the temperature relates to the nozzle. This should be clarified.
Add a check to the temperature input to prevent the user from entering a value exceeding the limit of the bed. If the user were to do this today, the process proceeds, but stalls as the bed will never reach the 220c of PLA.
The auto bed levelling does not work intuitively.
