marlin_*, these are ready to be flashed to the printer. The suffixes indicate the printer to which it belongs to -
There's already a handy script which downloads and flashes to the printer automatically
Flashing:
$ ./install_marlin.sh <machine> --release-version <version>
...
# this will download and install the v0.7 firmware for dreamer nx.
# follow the instructions pointed in the script
$ ./install_marlin.sh dreamer_nx --release-version 0.8.1You should see something similar --

Flashing Completed, your printer will now reboot to the new firmware!For flashing a specific firmware, download the binary from the releases page and use the python script
As it can flash any firmware supported by the printer, you can use this to restore the stock firmware.
$ ./ff_flash_firmware.py /path/to/firmware.binYou can use the python script to directly flash the firmware. If this is not possible you can follow the instructions here: https://github.com/moonglow/FlashForge_Marlin/issues/16
This option is currently supported only on macOs
./install_marlin.sh <machine> --restore-ff-firmwareNote:
If you encounter timeouts, restart the same process. It usually takes twice for stock firmware (see Issue#16 )
Once you run on Marlin firmware, you need to update the start and end g-code in your slicer. This is important because, some of the start gcode flashforge firmware are different and especially the motor control voltages are handled differently in Marlin and Flashforge firmware.
Here's a good starting point gcode I use.
; Start G-Code
; Initial setup
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M104 S[first_layer_temperature] ; set extruder temp
M109 S[first_layer_temperature] ; wait for extruder temp
M107 ; Fan off
G90 ; use absolute coordinates
G28 ; home all, this also disables previous bed level data
;Nozzle purge move
G1 X-70 Y-70 Z0.3 ;Move to bottom left
G1 X70 E20 F1500 ; Extrude across bed
G1 Y-69.6 ; Move up 0.4
G1 X-40 E20 F1500 ; part way back extruding
G1 X-70 F2000 ; Drain nozzle
G1 Z5 ; lift head
; End G-Code
; Start G-Code
G27 ; Park nozzle
G1 Z140 F{travel_speed*60} ; lower bed to present
M140 S0 ; turn off heatbed
M104 S0 ; turn off temperature
M107 ; turn off fan
M84 X Y E ; disable motors
M73 P0 ; reset print progress
M117 Print Finished;
; End G-Code
!! IMPORTANT !!
If you don't know what you are doing, do not proceed, use one of the per-compiled firmware binaries
!! IMPORTANT !!
You can add/change the machine specific configs in ./configs/ and add a ifndef for the related configuration in the common configuration file at ./Marlin/Marlin/Configuration(_adv).h and compile it as follows -
./build_marlin.sh dreamer_nx #build only, use ./ff_flash_firmware.py to flash this firmware
....
./build_marlin.sh dreamer_nx --flash # build and flash to printer directly
