Please kindly note that LERDGE-X motherboard has been upgraded to LERDGE-Z motherboard.

The LERDGE-X motherboard is the basic motherboard. Due to the user’s more functional requirements, the LERDGE-X motherboard has been upgraded to the LERDGE-Z motherboard, which adds an EX axis (changes to a 5-axis), which can be customized as dual X/Y/Z/E.

The LERDGE-K motherboard is a high-performance motherboard at present. The LERDGE-K may be upgraded in the future. Now the upgraded LERDGE-Z is also to replace the LERDGE-K motherboard, which is between the LERDGE-X motherboard and the LERDGE-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 can directly buy the LERDGE-Z motherboard, which is a combination of the two boards.

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

Resume Printing After Power Failure:

The Lerdge-Z 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 (included in the Kit).


High-power Hotbed:

The heated bed with a power of no more than 150w can be connected directly to the motherboard. If the heated bed power is more than 150W, please use a high-power hotbed module (included in the Kit).


Filament Run-out Detection:

The Lerdge Z 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 (included in the Kit) is needed.

Wireless Connection:

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

Temperature Control:

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

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 (not included in the Kit)

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 (not included in the Kit). The motherboard itself is recommended to drive 42 motor. As shown in the figure below.
