Hello, I have a purse i3. it was working just fine for the past 3 years. Recently one of the 4 mother drivers burned out. I ordered a set for all motors. Since than I keep getting temperature shut don in the middle of printing. I remember there is a way to adjust the pots on the drive circuit for x, y, z and extruder. But I forget what the proper voltages are. Is the the reason why the temperature shuts off when all the motors are at work? Thanks
