1.0 What is voron0

Voron0 is a highly accurate and compact open source 3D printer that uses the CoreXY system for fast and precise printing. Its frameless design makes it highly customizable and popular among DIY enthusiasts.

This was created by Hiroe Takeda(my aunt and instructor)!

1.1 specification

Compact and portable
120x120x120 build volume
CoreXY
Low mass direct drive extruder
Enclosed chamber
24v DC bed
Klipper firmware
Filament runout sensor

2.0 What is Vzbot awd 330

The VzBot AWD 330 is a high-speed, high-precision CoreXY 3D printer. It features stable operation with all-wheel drive (AWD). It is highly customizable and suitable for DIY.

This was created by Takeda Kazunari (my uncle and founder of west-harima)!

2.1 specification

Compact and portable
330x330x330 build volume
CoreXY with AWD (All Wheel Drive)
Low mass direct drive extruder
Enclosed chamber
High-power heated bed
Klipper firmware
Filament runout sensor
Auto bed leveling
500°C+ capable hotend
High-speed printing (1000mm/s+)

Maximum speed: 2500 mm/s acceleration 20000 mm/s^2, but for safety reasons, the maximum speed is operated at 1000 mm/s acceleration 20000 mm/s^2.

5.OrcaSlicer calibration¶

What is calibration for?

3D printer calibration is necessary to improve accuracy and quality.
The main objectives are as follows

Ensure dimensional accuracy: Ensure prints are sized as designed
Leveling the bed: Ensure good first layer retention
Adjusting the extruder: Ensure proper filament extrusion
Vibration and resonance suppression: Prevents blurring during high-speed printing
Temperature control: To print at the optimum temperature for each material

Calibration using Orca Slicer

Temperature Calibration
Flow Rate Calibration (Pass 1)
Pressure Advance Calibration

Important

Once the calibration process is complete, do not forget to create a new project to exit calibration mode.
When creating a new project, a window will appear saying, “There are unsaved changes in the current project. Do you want to save before continuing?” To prevent the settings from being accidentally overwritten, select “No” on the save screen.

Temperature Calibration¶

This process prints patterns in different temperature zones to see which ones print cleanly.

Select the printer in the upper left corner of the screen.

Select Fialament

Select “Calibration” > “Temperature”.

Since ELEGO’s recommended temperature is between 190°C and 220°C, set “Start temp” to 260°C and “End temp” to 230°C, then click the OK button.

They are all beautiful, but this time we will select 220 degrees, the most beautiful of them all.

Click on “Edit Preset” in Orca Slicer.

Calibration of flow rate (pass1)¶

If this is not appropriate, the molding may be fattened or, conversely, thinned.

Click “Calibration” -> “Flow Rate” -> “Pass1

It is difficult to choose one over the other, but I will choose -10 this time.

Pressure Advance Calibration¶

In a 3D printer, when the ex- and ruder accelerate or decelerate, the difference in pressure can change the thickness of the line. We will make adjustments to avoid such a situation.
