Welche Informationen zur Firmware sollten hier stehen?
Do you have a AnyCubic Chiron and want a stable firmware with the latest features? Maybe you’re adding our EZABL kit to the machine. This is the download for you. Directions are below. NOTE: This firmware ONLY works when using our Chiron LCD Upgrade kit. The stock LCD is not supported due to limitations with it’s closed source firmware.
You can purchase it from our website here: AnyCubic Chiron LCD Upgrade Kit – TH3D Studio LLC. We also recommend you download the Unified 2 STL pack as well. This contains EZABL mounts, Gantry leveling Blocks, Solid bed mounts, and Bed Level test files. Click here to go to the Unified 2 STL Pack download page.
1 –Printer Board Firmware Update. NOTE: These printers update over the USB cable from your PC to the printer. Make sure to have a USB cable ready. 1.a – Download the firmware.
1.b – Extract the files to a folder on your computer.
1.c – Open the folder labeled “Firmware” in VSCode. 1.d – Open the Configuration.h file that is located under the “Marlin” folder on the left side of the VSCode screen.
1.e – In the Configuration.h file, uncomment (remove the 2 / in front of #define) the CHIRON line and any other options you are going to use in the firmware. 1.f – Click the ✓ at the bottom of VSCode to compile the firmware.
The firmware will compile. This may take 1-5 minutes depending on the speed of your computer and internet connection.
2. Download and install Arduino IDE
1.g – If the build succeeds plug in your printer to your computer with the USB cable. 1.h – Now click the arrow (right pointing) to upload to the printer board. Make sure ALL slicers or other programs that connect to your printer board are CLOSED before trying to upload to your printer.
3. Connect Kossel to PC via USB
Please note that on machines with multiple COM ports you may have to select the COM port manually. Please see our VSCode COM port selection article to see how to do that. 1.i – The firmware will upload to the printer board over USB. DO NOT UNPLUG THE PRINTER OR RESET YOUR COMPUTER.Interrupting the flashing can “brick” your board and if this happens you will need to reflash the bootloader with a programmer (like an Arduino UNO) before you can flash again.
4. Modify Configuration.h
1.j – When the printer boots you will see the TH3D logo on your LCD. Make sure to reset your EEPROM on your printer after flashing any firmware.
You can do this from your printer LCD or by sending a M502 followed by M500 with your favorite Gcode sender application.
THIS FIRMWARE AND ALL OTHER FILES IN THE DOWNLOAD ARE PROVIDED FREE OF CHARGE WITH NO WARRANTY OR GUARANTEE FROM TH3D STUDIO LLC.
SUPPORT IS NOT INCLUDED JUST BECAUSE YOU DOWNLOADED THE FIRMWARE. TH3D STUDIO LLC IS NOT LIABLE FOR ANY DAMAGE TO YOUR PRINTER, PERSON, OR ANY OTHER PROPERTY DUE TO USE OF THIS FIRMWARE.
IF YOU DO NOT AGREE TO THESE TERMS THEN DO NOT USE THE FIRMWARE. We do not maintain a full change log for this firmware. However, you can track all changes and modifications to our firmware code on the GitHub repo for Unified 2 Firmware.
Auf dem Board des Anycubic i3 Mega ist eine vom Hersteller modifizierte Version der verbreiteten Marlin Firmware, die den aktuellen Standard auf dem Markt darstellt.
Diese Seite ist noch nicht fertiggestellt, aber eine der wichtigsten Grundregeln greift auf jeden Fall:.
Wenn es keinen wichtigen Grund gibt, die Firmware zu ändern, insbesondere wenn du vielleicht noch Anfänger im Bereich 3D-Drucker bist, dann lass da besser die Finger von. Die Chance, etwas grundlegend zu zerstören, ist dabei doch recht hoch.
Der ebenso gute wie günstige Anycubic i3 Mega braucht für den normalen Anwender keine Modifikationen der Firmware.
4.5. Rod lenght
Measure the correct lenght of your rods by disassebling and measuring them with a sliding meter axis to axis – hole diameter and correct the value
4.6. Probe edge
If your printer is probing very near the edges of the bed, you could modify this parameter.
It is a minimal distance of the probe’s microswich from the edge of the bed.
4.7. Safe zone – moving the head down after G28 – home
This variable causes the printing head to move approx. 50 mm down after homing at the end of a printing session.
If you are going to print tall models, please comment this line:
4.8. Maximum speed
A standard Kossel without corner reinforcements, belts well tensioned can do about 60mm/s max.
If you have these upgrades, you can easily achieve 100mm/s and even larger speed.
4.9. Maximum acceleration
You can define maximum acceleration values in this part of the configuration file.
Just keep in mind, that if you want to print with higher acceleration, the FW will not allow you to do that.
I consider these values as a “failsafe” against too high acceleration values.
4.10. Restore autoleveling
This is almost critical.
For anyone using another FW, check if this line is defined.
It ensures that after a reboot, the printer will still use values from your delta calibration.
There is also another solution:
Placing M420 S1 after G28 in start G code in your slicer
4.11. Homing speed
Homing speed is a crucial setting. It allows you to lower homing speed making homing and calibration more precise.
Instead of a fast homing and “crushing” into end stops you can slowly approach and trigger them.
4.12. Probing speed
XY_PROBE_SPEED – XY movement between probing points in mm/minute
Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z – slow probing speed is equal to HOMING_FEEDRATE_Z
Z_PROBE_SPEED_SLOW – slow probing speed set up to a one third of Z_PROBE_SPEED_FAST
5. Upload new Marlin FW
In Arduino IDE click on Tools and choose Mega 2560 as a board and ATmega2560 as a processor.
Pick the correct COM port (you can check that in device manager, com ports).
Click on Projects and upload.
Or simply use Ctrl + U shortcut.
The moment you see Upload complete you can disconnect the printer and calibrate your bed.
6. Delta calibration
This important calibration measures each end stop’s position and arm lenght.
Is also auto levels your bed.
7. Hotend PID calibration
You also should perform PID calibration to get rid of any thermal runaway problems.
