Lerdge-X Board V1.0.7 Firmware --Update Time:2018.09.12

NOTIC:

1. Decompress the file and copy the entire folder of "Lerdge_system" to the TF card or U disk root directory (must be the root directory, or may appear to "cannot find the UI file" problem. If you don't know what is the root directory, please Google it. : )  )

2. Boot, select the TF card or U disk that with the file to upgrade in the "Settings" -> "System" -> "System Update (up arrow icon)".

3. Select the "Lerdge_firmware_v2.0.0 (beta1). Bin" file  in the "Firmware" folder, then you can upgrade the firmware.

Note: Do not modify the file name or file path!!!!!

 4. The machine parameters will be reset after the firmware updated, and users need to re-set all the machine parameters. So, please backup the parameters in advance, or pre-configure the configuration file for recovery.

 

When it shows "no find APP!", means updating the firmware fails. The board need to be mandatory updated.

Note: Users must use the TF card for the firmware mandatory updating. U disk cannot achieve that.

1. Rename the firmware file in the the "Lerdge_system" folder to be "Lerdge_firmware_force.bin" after decompressing. And then copy the entire "Lerdge_system" folder to the TF card root directory (must be the root directory).

2. Insert the TF card into the motherboard, reboot, the system will process the mandatory update.

3. Remove the TF card, and delete its root directory "Lerdge_system" folder, to avoid the mandatory update operation again when boot next time.

2. Open the enabling of saving temperature when accidental power off happens that closed in 1.0.4 version

3. It will show the specific error hotend number when hotend error alarm occurs, to confirm the hotend problem (used to identify whether it is hotend problem or headed bed problem)

4. Fix the repeated homing action during the automatic leveling.

5. Fix the bug of the screen failure caused by the touch calibration failure after inverting the UI.

6.The name of the print file is added to the prompt box after the printing is finished to confirm the printed file.

6. Add the reset angle of automatic leveling probe. And when for bltouch error status, reset the motherboard, the bltouch will be reset as well.

7. Fix the issue that the host computer can not read the temperature when the online connected.

8. Modify the control logic of the mobile interface. The axes that without homing can also be controlled directly without forced homing.

9. Change the stop position (when paused) from the original fixed (3,3) coordinate point to the position determined by the origin setting position.


Lerdge-X V1.0.2

1. Fix the bug of the Z axis rise when Delta printers dual heads switching.

2. Add the prompt interface when there is device fault during the offline printing, to solve the crash problem caused by the storage device.
