  1. Hello all. Did somebody try this setup? I have UMO+ with two sensors and two thermal couplers. I am going to compile new firmware but I am questioning 2A more power on the motherboard... Will that be a problem? Can safe work around be adding 2 resistors on heaters to lower amps on them? Heating would be slower but power supply and amps trough the board would stay the same... If 2A goes trough the heater on 24V that means heater resistance is 12ohm, so strap on 12ohm resistance each nozzle heater would give 24ohms and 1A current. If now it takes about a min to heat up with 2A, it might need 2 minutes with 1A. Or put 20ohm resistance and get a little overload. 20ohm 30W resistors cost arund 5USD Cheers
