¶ MD 600D First Print
¶ Video Guide
需要一个使用视频
This video mainly demonstrates the first printing process after unboxing the machine.
- Printer Calibration
Please follow the sequence shown in the diagram to calibrate step by step.
Note: After the printer print something, the nozzle needs to be cleaned before calibration.

- Z Clibrate Clibration
This is used for calibrating the leveling sensor which installed on the extruder.
Click Calibrate> Z Calibrate > Start
The same operation as the Z endstop calibration.
Place an A4 sheet of paper between the nozzle and the heated bed. Gradually lower the nozzle until it just begins to press against the paper, allowing the paper to slide with slight resistance. Once the optimal position is reached, accept the settings. Then save the value, and the printer will restart itself.
- Auto-Leveling
This is used for calibrating the whole buildplate.
Click Calibrate> Leveling > Calibrate
The printer will start autoleveling automatically after clicking Calibrate. And it will take around 2 minutes.
Before starting the leveling process, heat the bed to 60℃ and wait for 20 minutes. This allows for thermal expansion of the glass to stabilize, ensuring accurate leveling.
- XY Offset Calibration
Click Calibrate> XY Offset > Start
This is used for confirming the nozzle possion.
|
|
|
- The cali-camera will light up after clicking "XY offset". After the camera LED lights up, click "Start", and the left extruder will move to the calibration camera's position automatically.
- Adjust the left extruder nozzle to align with the crosshairs of the screen and click "Confirm Pos", the right extruder will move upon the camera automatically.
- Adjust the right extruder nozzle to align with the crosshairs of the screen click Confirm Pos, then Save. The printer will restart itself.
- Z Height Diff Calibration
Click Calibrate> Z Height Diff > Start
This is used for confirming the nozzle height.
 |
 |
|---|
While calibrating the Z-axis offset, the extruder will move towards the sensor automatically. Please observe if the nozzle is positioned above the probe sensor. If not, use the Adjust Zprobe Pos function to adjust the nozzle.
- Adjust Zprobe Pos
This is used for making the nozzle on the top center of the sensor manually.
 |
 |
|---|
Click “Start” and move the XYZ axes to position the nozzle directly above the center of the metal sensor. Then save the value. After that, perform the “Z Height Diff” procedure again.
- Calibrate PID
This is used for calibrating the nozzle temperature.
 |
|---|
Before using the machine for the first time, it is essential to perform temperature calibration.
The nozzle's compensation values must be adjusted according to different ambient temperatures. Proper calibration ensures accurate and stable temperature control during printing, thereby improving print quality
- Insert Filament
You can find and open the left side filament cabinet door to hang the filament.
|
|
|:-
:-
Hang the filament onto the filament holder as shown in the picture, and insert the filament into the corresponding tube one by one. Pay attention to the direction of insertion. The T0 is for left extruder, and the T1 is for right extruder. The internal gears will automatically pull the filament into the feeding tube near the extruder. Then heat up the nozzle to target degrees and load the filament until it out from the nozzle.

- Printing
Please print the testing gcode on the printer firstly to test the printer.
Printing Tips:
During printing, if the model is too close to or too far from the build plate, you can use the fine-tuning function to adjust the nozzle height:
-
Tap "Fine Tune".
-
Select a tuning step of 0.02, then use Z+ (raise the nozzle) or Z− (lower the nozzle) to adjust the height until the extrusion lines are evenly laid and properly aligned.
Proper fine-tuning helps achieve optimal first-layer adhesion and print quality. For more information about the first layer printing, please click here.
