Hi, I put the E3D V6 hotend in my printer, and I'm running into an issue where the printer is not getting hot enough. I flashed the firmware with the modifications to the thermister settings, and even replaced the thermister with a brand new one. The hot end heats up, and gets pretty warm, but not warm enough for the plastic to flow. It just gets jammed up. To install the heater, I took the heater cartridge wires and just connected them to the old wires without unplugging them from the board, so it's definitely in the correct spot. I'm wondering if the power supply is not sending enough current to the heater. If I hook up my multi meter to the heater wires, what reading should I be looking for?
