Resume Printing After Power Failure:

The Lerdge-X motherboard comes with the functions of printing pause, printing saving, and restarting printing after power-on. However, if you need to the feature of saving the printing after unexpected power failure, and the feature of shuting down after printing completed, you need to equip the power monitoring module.

High-power Hotbed:

The Lerdge X motherboard cannot be directly connected to the hotbed, a hotbed expansion adapter is required. And if the heated bed power is more than 150W, please use also a high-power MOS hotbed module.

Filament Run-out Detection:

The Lerdge X motherboard can pause printing when the filament is run out,and then resume printing after the filament is loaded. In order to identify the signal, an filament detection sensor is needed.


Wireless Connection:

The Lerdge X motherboard defaults to offline printing (Use TF card or U disk printing). You can realize the wireless communication between the Lerdge X motherboard and the computer through serial and WIFI connection. At this time, an online module and WIFI module is needed.


Temperature Control:The Lerdge motherboard adopts PID temperature control to make the printing temperature more stable.


Automatic Leveling:

Ledge K has a patented automatic leveling solution, the number of automatic leveling points can reach up to 1024 platform sampling points,which realize efficiently the adjustment of the platform and make the printing quality better. Regarding the automatic leveling module, we recommend this pressure film sensor.

External Drivers:

For large-size printer, if you need to connect external drivers to a large motor, such as 57 motor, 86 motor, etc., please purchase an external driver adapter module. The motherboard itself is recommended to drive 42 motor. As shown in the figure below.

Only X Board(NO DRIVERS,NO 3.5-INCH TOUCH SCREEN):If you already have a driver modules, you already have a 3.5-inch touch screen, you can buy Only X Board.
Tip: The Lerdge X motherboard have to match with our 3.5-inch touch screen to be used.
