Ramps 1.4 help setting up dual extruder, fan and heated bed. I am switching from a MKs board to a RAMPS 1.4 board in order to run EEFB. Being new to Ramps (and 3d printing as well....3 months under my belt LOL) any help in setup and configuring Marlin to run everything would be welcomed. I am aware of how to configure the setup for EEB but I am adding a fan extender board and would like some info on what needs to be changed in Marlin to run my filament cooling fan along with the dual hot ends and heated bed. Thanks in advance. https://reprap.org/forum/read.php?219,630136,630136#msg-630136 Wed, 22 Jul 2026 04:19:38 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,630136,630415#msg-630415 Re: Ramps 1.4 help setting up dual extruder, fan and heated bed. https://reprap.org/forum/read.php?219,630136,630415#msg-630415
#define BOARD_RAMPS_13_EEB 34 // RAMPS 1.3 / 1.4 (Power outputs: Extruder0, Extruder1, Bed)

As well as EEB setup, it'll define the necessary pins to work with the fan expansion]]> Muleo RAMPS Electronics Mon, 22 Feb 2016 22:02:23 -0500 https://reprap.org/forum/read.php?219,630136,630136#msg-630136 Ramps 1.4 help setting up dual extruder, fan and heated bed. https://reprap.org/forum/read.php?219,630136,630136#msg-630136
