Hack/Mod Ramps 1.4 for Dual X or Y Carriages Hey reprapers, i am looking to adapt a mod for either Dual X or Dual Y carriages for a 3d printer on the RAMPS 1.4 board The goal is to separate a single module dual head extruder into 2 separate extruder heads each independently controlled by their own X or Y carriage.

Cant find the dual x carriage support in config.h Therme ist just an Entrance in config ADV.h
But if i define it i got a failure in pins.h

#define __EPIN(p,q) how can i fix it?


Thanks for your help.]]> bj1986 RAMPS Electronics Sun, 07 May 2017 15:36:22 -0400 https://reprap.org/forum/read.php?219,517033,540703#msg-540703 Re: Hack/Mod Ramps 1.4 for Dual X or Y Carriages https://reprap.org/forum/read.php?219,517033,540703#msg-540703 willysan RAMPS Electronics Sat, 01 Aug 2015 21:49:45 -0400 https://reprap.org/forum/read.php?219,517033,540454#msg-540454 Re: Hack/Mod Ramps 1.4 for Dual X or Y Carriages https://reprap.org/forum/read.php?219,517033,540454#msg-540454 schematic is here in the first post.
The pins 23, 25, 29 are all located on AUX4.

It wasn´t necessary to power both hotends at once, because the slicers I know only generate code for one nozzle at a time.

I have to apologize, I didn´t know, that Marlin has such settings.
A second x-axis would be the easiest adation. Just put two frames vis-á-vis on one y-carrier.

But still I don´t see the benefit.
I´m getting curious :D

When you´ve managed to implement it in Marlin, how would you tell the slicer you have two independent extruders?

What would be the benefit of two independent extruders? The RAMPS fuse can´t power both hot ends at the same time. ( SS-Relais would help )
If it´s just about printing dual color at higher speed, you better build a second printer and reach that goal easily. :)

Only my 2 cent....

i did not realise that the Ramps fuse can't power both hot ends at the same time... :(

Ramps does support dual hot ends as it's specifications correct? If Ramps can't run dual extruder, why did they put that in there? Could someone please verify running both hot ends at the same time? Thanks



configuration.h supports

// If the machine can independently move the second extruder on the X or Y axis
// uncomment the appropriate define and uncomment/use paramters with X0/X1/Y0/Y1
// instead of X/Y in their name (those are dual drive specific).
//#define DUAL_X_DRIVE
//#define DUAL_Y_DRIVE

i am looking to adapt a mod for either Dual X or Dual Y carriages for a 3d printer on the RAMPS 1.4 board

The goal is to separate a single module dual head extruder into 2 separate extruder heads each independently controlled by their own X or Y carriage.





based off the wiring schematics, Aux 2 from the RAMPS 1.4 board can be used for the additional X2 stepper driver

The free pins on Aux 2 can be added into the pins.h file by defining them in the software

// For RAMPS 1.4
#define X2_STEP_PIN 5
#define X2_DIR_PIN 9
#define X2_ENABLE_PIN 10

These are the available and free pins on AUX 2 and not in use

and not to forget a 10k resistor to VDD

VDD, M1, M2, M3 connected to +5V

Am i missing anything?

thanks for the help :)-D
