Description: -  If you build or upgrade your printer with/to DUAL-EXTRUSION (2 extruders) including a heated bed all the output ports (D8, D9, D10) will be used. In this case, there is no option to connect a firmware controlled FAN to RAMPS board directly. However, in Sprinter/Marlin firmware there is an option already (Marlin: BOARD=34) which redirects the FAN to RAMPS output D4. But this solution needs a "buffer/driver" in order to work. -  The RRD-FAN-EXTENDER is exactly what you need in this case. It is a plug and plays solution to mount the FAN for DUAL-EXTRUSION setups with RAMPS1.4. But instead of adding only one additional output port the RRD-FAN-EXTENDER is equipped with 2 PWM controllable channels(D6/D11). The second channel can be used for another fan(e.g. to cool the stepper driver) or for adding light control (e.g. add dimmable LED light to your machine). Specifications:   - Support Max 20V - 2 (PWM controllable) channels (D6/D11) - Easy to install, Plug and Play - Support per channel Max 0.5A, enough for a big fan  - Flexible output voltage (you can connect the RRD-FAN-EXTENDER to 12V,5V,... in order to support the output voltage you need) - Already supported by Marlin firmware (choose "#define MOTHERBOARD 34") - Easy to adapt to other firmware (e.g. Sprinter: just change "#define FAN_PIN 6" in "pins.h")   Features: 1. You need Marlin firmware v3 or newer. If you are using the older firmware, you must re-flash your board. 2. Power up, two connecting fans will take turns to rotate. 3. Can be connected follow the description picture. Click for more information   Package included:   1 x Reprap Ramps1.4 RRD Fan Extender (The fan and the board are not included)

About MKS - GEN Mainboard:   1, Assemble 2560 and ramps1.4 on a board to solve the problem of complex interface and easy failure of the Ramps1.4 interface. 2. Replaceable motor drive, support 4988 drive and 8825 drive, TMC2100 drive, s109 drive 3, Reserved external drive signal, can be connected to the external drive to drive 57, 86 motors. 4, The use of high-quality MOSFET tube, heat dissipation better, to ensure long-term stability. 5, The use of dedicated power chip, support 12V-24V power input, to solve the Ramps voltage conversion chip heating, inadequate power supply problem. 6, 24V input can be accepted. Under the same system power, the hotbed current can be reduced to 1/4, effectively solving the problem of heat pipe MOS heating. 7, The use of open source firmware Marlin, configuration and ramps1.4 exactly the same, can directly replace Ramps1.4. 8, Can be directly connected to the 2004LCD display and 12864LCD display, can support TFT28, TFT32 touch screen. 9. Reserve the motor pulse and direction output port to facilitate the external high current to be connected to a large current (such as 2A, 5A) motor drive circuit. 10. Retain the Servos, AUX-1, and AUX-2 interfaces on Ramps1.4, providing three 5V outputs and three 12V output interfaces.   About TFT32 Display: Compatible with Marlin/Smoothieware/Repetier firmware Appearance size: 110mmX65mm Hole size: 102mmX57mm Color touch screen: 3.2 inch touch screen Microprocessor: 32-bit STM32 processor Update method: SD file update Support SD card, U disk Support file format: Gcode Scalable application: WIFI module, after the shutdown module,Cut-off inspection switch, power-off continuous, external card slot Package Included: 1 x MKS-GEN L motherboard 1 x TFT32 display 5 x A4988 red drive 5 x Heat sink 1 x USB cable 1 x  FC flat cable
