Dondolo X Carriage Kit to fit on "Acrylic Geeetech I3 Pro B with metal kit parts"
The purpose of this design is to install the "Dondolo" on the Geeetech I3 Pro B without losing the z-stroke, otherwise the stepper motor and the servo would hit the top of the chassis. Here is the reason for the 13mm spacer. The fan duct has been redesigned to fit the new configuration. Another necessary change was to move the belt holder higher than the original "Dondolo" carriage.

The project has finally been completed!
First of all a big thanks to Alberto (MagoKimbra) for debugging his MK4Duo firmware which now works perfectly with the "GT2560" board.
And of course Gianni Franci for the wonderful concept.
You can configure your firmware on MagoKimbra's page: http://www.marlinkimbra.it/
The firmware to be configured is this: "MK4duo - Firmware configurator tool (Rev 4.3.2x) - Firmware Version 4.3.29 dev"
Configure everything through the web interface, at the end check the assignment of the servo pin, that for the GT2560 Rev A+ must be Pin11 (maybe 13 for the Rev A)
Edit the file "7.h" located in this folder: MK4duosrc boards
as shown below
// ### SERVO
// #define SERVO0_PIN 32
If you want to use the original Marlin firmware, you have to make the changes you find in the documentation of Gianni Franci "DONDOLO_v1_firmware_setup_guide.pdf" and then, in "Configuration.h", put false in "#define DISABLE_INACTIVE_EXTRUDER"
as shown below
// Disables axis when it's not being used.
Remember, however, that the original marlin does not allow the Z offset between the two nozzles.
