WARNING: This profile adds support for the Dual Extruder Dreamer 3D printer flashed to Marlin firmware. This profile does NOT work with FlashForge factory firmware due to differences in the G-Code! DO NOT attempt to use this profile on factory firmware without changing the G-Code first!

I have tested this profile with Cura 5.2.1 with good results, but it may not work 100% correctly. Please submit an issue if you run into any problems, or if you have a change suggestion, please submit a pull request.

Installation Instructions:

Please follow the below instructions to install this profile to Cura:

1. Download the latest release .zip from here.
2. Unzip the files into your Cura install directory:
   • Windows: "C:\Program Files\Ultimaker Cura {Version}\share\cura\resources"
   • MacOS: /Users/{Username}/Library/Application Support/cura/{Version}/
   • Linux: ~/.local/share/cura/{Version}
3. After unzipping, open Cura and select the printer under FlashForge > Dreamer

G-Code (Marlin):

The G-Code between FlashForge firmware and Marlin firmware are quite different, and incompatible with one another. To fix this for Marlin firmware, the profile uses the below Start & End G-Codes:

Start G-Code:

;Start Gcode
G90
M141 S{build_volume_temperature}     ;Set chamber temperature for cooling fans
M140 S{material_bed_temperature_layer_0}     ;Heat bed up to first layer temperature
M190 S{material_bed_temperature_layer_0}     ;Wait for Heat Bed temperature
M104 S{material_print_temperature_layer_0}    ;Set nozzle temperature to first layer temperature
M109 S{material_print_temperature_layer_0}    ;Wait for Extruder temperature
M107 ;start with the fan off
G28
M117 Purge extruder
G1 Z50.000 F420
;Purge line
G1 X-110.00 Y-60.00 F4800
G1 Z{layer_height_0} F420
G92 E0
G1 X-110.00 Y60.00 E17,4 F1200
;Purge line end
G92 E0
G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed

End G-Code:

;end gcode
M140 S0 ; turn off heatbed
M104 S0 ; turn off temperature
M107 ; turn off fan
M141 S0 ; turn off chamber temperature
G28 X Y
M84 X Y E ; disable motors

G-Code (FlashForge):

The Factory G-Code support is a WIP. Eventually I plan to have separate releases for Marlin & FlashForge firmware profiles.

I have NOT tested these G-Codes with Cura, USE AT YOUR OWN RISK!

Start G-Code:

M118 X17.70 Y17.70 Z34.89 T0
M107
G90
G28
M132 X Y Z A B
G1 Z50.000 F420
G161 X Y F3300
M7 T0
M6 T0
M651
M907 X100 Y100 Z40 A100 B20

End G-Code:

M104 S0 T0
M140 S0 T0
G162 Z

M132 X Y A B
