The LERDGE-X motherboard is the most basic motherboard. Due to the user’s more functional requirements, the LERDGE-X motherboard has been upgraded to the LERDGE-Z motherboard, adding an EX axis (changes to a 5-axis), which can be customized as XYZE, and some intelligence The breathing light recognizes the status of the machine and other functions.

The LERDGE-K motherboard is a high-performance motherboard at present. Because LERDGE-K may be upgraded in the future, the upgraded Leji-Z is also to replace the LERDGE-K motherboard, which is between the LERDGE-X motherboard and the Leji-K motherboard. In the meantime, only the functions that are not commonly used on the LERDGE-K motherboard have been removed, but the price has been reduced.

In a word: Customers who want to buy the LERDGE-X motherboard or the LERDGE-K motherboard directly buy the LERDGE-Z motherboard, which is a combination of the two.

Only Z Board:（NO DRIVERS,NO3.5-INCH TOUCH SCREEN ）

If you already have a driver modules, you already have a 3.5-inch touch screen, you can buy Only Z Board.

Tip: The Lerdge Z motherboard have to match with our 3.5-inch touch screen to be used.

Note: The Lerdge-Z motherboard does not support TMC series UART/SPI mode

About the power continued to play function:

Lerdge-X motherboard comes with print pause, print save, boot continue to print function. For accidental power outage, power failure to save continued playing, shut down after printing finished functions, the additional power monitoring module is required.

About printing:

Lerdge-X motherboard supports off-line printing by default (TF card printing or USB printing). If you need online printing, an is needed.

About heated bed:

If want to use Lerdge-X motherboard with heated bed, are required.--Recommended USB and SD card is no larger than 32G.

Motor Driver Cooling Fan Interface：

When any motor drive is enabled, the fan is turned on;

When all motor drives are disabled, the fan is turned off.

Hothead0 Cooling Fan Interface：

When the temperature of the hot head is higher than 45℃, the fan is turned on；

When the temperature of the hot head is lower than 40℃, the fan is turned off.

Ex-Motor Interface：

Ex axis can be used to synchronize X\Y\Z\E0 motor movement or expand to E1 motor interface.

System Reset Interface：

A two-wire normally open switch can be connected here to realize the emergency stop button.

Servo Power Selection Pin：

Select the servo power supply voltage between 5V and the mainboard power interface voltage,

short-circuit the middle and left pins, and select 5V power;

short-circuit the middle and right pins, and select the Power interface voltage.

The comparison between Lerdge Z and Lerdge K, Lerdge X is as follows：

Compared to other boards:

Automatic Leveling:

Lerdge Z 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.
