Firmware Stock

In this page, you can find the links to a github repository where we store tested firmwares for the Flyingbear Ghost 5 and 4S and the procedures to update your 3d printer

How to check currently installed version

From the main menu, click on the Tool icon
Click on the About icon
Next to Mainboard Version, you should find the current installed version

Update procedure

Download the zipped file that contains the firmware
Extract the file you've just downloaded to a folder you can easily locate
Insert the printer microSD card to your computer
Backup all the files stored in the microSD
Format the microSD card in FAT32
Copy the whole content of the folder where you extracted the firmware to the microSD (both files and folders)
*Optional: If you've amended the robin_nano35_cfg.txt config file in the past, insert all the values you've amended in the new config file in the firmware folder
Switch the printer off (if on)
Insert the microSD card in the printer
Switch the printer on
Wait for new firmware to be uploaded
When update is complete, you should be able to see the Flyingbear logo first, then the startup menu

danger

DO NOT switch off the printer during the update procedure!!!

Increase printing speed

The stock firmware limits the printer speed: it can reach much higher speed and acceleration

This limitation is the main reason for discrepancies between estimated print time from the slicer and the actual printing time

To increase the printer speed limits, replace the following values in the robin_nano_cgf.txt and update the firmware as described in the First Steps section of this wiki

 >DEFAULT_X_MAX_FEEDRATE        300
 >DEFAULT_Y_MAX_FEEDRATE        300
 >DEFAULT_Z_MAX_FEEDRATE        5
 >DEFAULT_E0_MAX_FEEDRATE    100
 >DEFAULT_E1_MAX_FEEDRATE    70
 >DEFAULT_X_MAX_ACCELERATION    1000
 >DEFAULT_Y_MAX_ACCELERATION    1000
 >DEFAULT_Z_MAX_ACCELERATION    200
 >DEFAULT_E0_MAX_ACCELERATION    80000
 >DEFAULT_E1_MAX_ACCELERATION    1000
 >DEFAULT_ACCELERATION        1000
 >DEFAULT_RETRACT_ACCELERATION    3000
 >DEFAULT_TRAVEL_ACCELERATION    1000
 >DEFAULT_MINIMUMFEEDRATE    0.0
 >DEFAULT_MINSEGMENTTIME        20000 
 >DEFAULT_MINTRAVELFEEDRATE    0.0

Available firmwares

tip

We store only firmwares we've tested

These firmwares might be behind the ones released by Flyingbear, which you can find here

However, we cannot guarantee these firmwares won't brick your motherboard, while we can guarantee you the ones we are hosting won't

danger

Lately, Flyingbear delivered printers with different motherboard chipsets and drivers

Before you download and install a new firmware, you should double check which configuration you have

Unfortunately, the only way to do this is to open the printer base

We stronlgy advise you not to attempt to install firmware blindly: installing the wrong firmware might brick your printer (lucky for you, there is already a procedure to restore the bootloader, which is described in the next page)

Compare your configuration with the pictures in the table below, then choose a firmware to install

If you can't see very well the images below, just click on them: a new zoomed in image will open in another window, so you can see better
