About power continued to play function: Lerdge-K motherboard comes with printing pause, printing save, and start-up function. But if you need the function of saving power and continue to play when power off unexpectedly, and the function of automatically turning off after the printing finished, apower monitoring module is needed.
About printing instructions: The Lerdge-K motherboard defaults to offline printing (Use TF card printing or U disk printing). If need the online printing, an online module is needed.
About the Lerdge-K motherboard auxiliary motor function description: The auxiliary motor can be used for dual X-axis, dual Y-axis, dual Z-axis or copy extruder E0 or extruder E1 (depending on the specific model of the printer), but it can not be used for the third extruder.
About the use of heated bed: The heated bed with a power of no more than 150w can be connected directly to the motherboard. If the heated bed power is too large, please use a high-power MOS hot bed module.
About the USB port instructions: Note that the USB port can not be directly connected to the computer as a power input port. The USB port can be extended with a U disk, but please make sure the extension cable should not be used too long. In order to avoid the printing process failure, it is recommended to use the brand genuine U disk. The expansion disk or recycling U disk may lead to problems such as identification or printing crash.
For large-size machines, if you need to connect externally, please purchase an external driveadapter module to drive a larger motor, such as 57 motor, 86 motor, etc. The motherboard itself is recommended to drive 42 motor. As shown in the figure below.
