TABLE OF CONTENTS


K1 Series (K1 / K1C / K1SE): (AU: 220 - 240V):


If you wipe the graphite plate with alcohol or any liquid make sure that it is completely dry before gluing the heater and magnet!!! Graphite has pores and liquid will be trapped inside it and will make the glue bubble when heated.

I suggest gluing the magnet on a 100C hot bed (the last step of installation) to make sure the graphite is dry and it glues flat. This was tested couple time and worked great.

Before installing I suggest printing the SSR mount that you can install on the rib right next to the motherboard:

And bed leveling knobs for M4 screws:

The 500W AC heater has inbuilt 150C self-recovery overheat protection switch for safety.
It has 5 wires:
2 red wires = thermistor
2 white and 1 yellow wires to connect to either 220v or 110v:

220v: ignore the yellow wire and connect white wires only
110v: connect 2 white wire together to one terminal and the yellow wire to the other.


Wiring Guide:

  • Ground Wiring (Wiring, require re-crimp one end to RV1.25-4) Use the one of back 2 build plate alignment to secure ground wiring with lock washer, you may need source slight longer fasteners if you're using lock washer. The Ground can wire to the power supply shared GND.


Software: 

Thermistor type is NTC 3950 100K. in "printer.cfg" change the sensor_type to sensor_type: NTC 100K MGB18-104F39050L32 and do the pid calibration in the console: PID_CALIBRATE HEATER=heater_bed TARGET=100



K1 Max (K1 Max): (AU: 220 - 240V):

K1 Max already has an SSR so it is not included in the kit. Follow the pictures to connect it correctly.
