I have a Monoprice Mini. V2. It has been printing very well - I did a few mods like changing the mount and fan for the extruder and really improved the quality of printing. However, I just started the unit up and the hot plate was off, but indicated 326C. If the thermistor wires were broken, they would show either 0 or 999 depending on whether it is upscale or down scale break protection (999 is safer). Have I fried something? Or is it just the wiring that I have to replace and do the “no-drill” mod to route the wires out of the back of the build plate?

Thanks

Scott
