Hi all.
I have a Mk3 Heatbed wich can be supplied with both 12 and 24 volts. My problem is, that when running on 12 volts it can get higher than 97C due to low room temperature (we are in the middle of the Nordic winter). I would like to run it at 24 volts besource I have testet it externaly with 24 volts and then there is no problem with getting higher temps.
So I need help to make system where my Melzi board controls some sort of a relay with the board heatbed output.
Happy printing
