Eazao kit firmware tutorial for other printers

Eazao kit is suitable for most open source FDM 3D printers, including but not limited to FDM models of the following brands: Creality, Anycubic, Artillery, Elegoo, etc.

Although we are currently only upgrading for Ender 3, other FDM printers are also possible. For the modification of the firmware part, please refer to the following process, and upload it to the printer after modification. You need to design the fixed mechanical part of the extruder yourself.

Note: After uploading the firmware, if you want to perform the previous FDM printing, you need to upload the original firmware.

The following tutorial uses Marlin as an example to introduce. You can find here: Ceramic 3D Printer Kit

This kit contains the following parts:

1 x Eazao Zero electric putter kit, 1 x Eazao independent control board, 1 x 12V power adapter, 1 x Ender 3 adapter, 1 x Tube.

For technical questions, please contact: support@eazao.com.

If your FDM model is not Ender 3, you need to modify the printer’s firmware and upload it to the printer. Below we take Marlin firmware as an example to modify, other firmware can refer to this modification, mainly to modify the temperature setting and extruder resolution:

1. Modify the temperature sensor and set the temperature sensor model to 998.

#define TEMP_SENSOR_0 998
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_3 0
#define TEMP_SENSOR_4 0
#define TEMP_SENSOR_BED 998
#define TEMP_SENSOR_CHAMBER 0

2. Turn off the temperature protection, that is, change the minimum temperature from 170 to 0.

#define PREVENT_COLD_EXTRUSION
#define EXTRUDE_MINTEMP 0

3. Change the Axis Steps Per Unit to 600.

#define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 400, 600 }

4. Add the M302 command in Start_gcode.

For details, see the software setting part in the Eazao Zero manual.

Start_gcode:
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G1 Z15.0 F1500 ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
M302
G1 F1500
M302 S0 ; always allow extrusion (disable checking)
M163 S0 P0.9 ; Set Mix Factor
M163 S1 P0.1 ; Set Mix Factor
M164 S0

Note: Be sure to change the temperature setting part in the slicing software to 0.

*** We have only personally upgraded Ender 3, other printers have not done experiments, but it is theoretically feasible and does not guarantee the success of the upgrade. If the modification fails, Eazao reserves the right to explain.

    Hi!!
    I have the Ceramic 3D Printer Kit and a Creality ender Max.
    I just download the TH3D_Unified2_CrealityV4X firmware (https://www.th3dstudio.com/hc/downloads/unified-2-firmware/creality/creality-ender-3-max-firmware-v4-2-x-board/) to modify it with the parameters you set, I just can’t find all the ones mentioned in the tutorial.
    This is the code:

      You can not modify the firmware first, just follow the tutorial to modify cura. If you need to modify the marlin firmware, please contact your machine manufacturer and let them provide you with the marlin firmware. The version you provided cannot be edited.
