Overview

Fan1.jpg Fan2.jpg


If you build or upgrade your printer with/to DUAL-EXTRUSION (2 extruder) including a heated bed all the output ports (D8,D9,D10) will be used. In this case there is

not 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 play 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 controllabe 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).


Features:

  • max 20V
  • 2 (PWM controllable) channels (D6/D11)
  • max 0.5A per channel (enough for a really big fan)
  • flexible output voltage (you can connect the RRD-FAN-EXTENDER to 12V,5V,... in order to support the output voltage you need)
  • each channel has a fly back diode
  • easy setup (plug and play)
  • already supported by Marlin firmware (choose "#define MOTHERBOARD 34")
  • easy to adapapt to other firmware (e.g. Sprinter: just change "#define FAN_PIN 6" in "pins.h")



Firmware:

Firmware:

You need Marlin firmware v3 or newer. If you are using older firmware, you must re-flash your board.

The latest Marlin firmware is available here:https://github.com/ErikZalm/Marlin
