Bed temp mod for Up! Mini

thingiverse

This is a simple upgrade for the Up! Mini 3D Printer's bed temperature control. Switch between 60°C and 100°C easily by adding a second temperature controller in parallel using a switch. When powered up, a red LED lights up immediately, while a green LED turns on when the chosen temperature is reached, giving you full control over your prints. Just install a second temperature controller at 100°C and connect it to the original one through a switch. The two LEDs are connected with 3.3K resistors because the bed is powered by approximately 18V DC. One LED lights up directly from the bed power connector, while the other shares its connection with the 60°C controller. The wires used have a high-temperature silicone insulation to prevent damage from extreme heat levels. Secure the switch in place on the bed using epoxy resin (Poxipol) that can withstand temperatures of 100°C.
