Quick Start Guide

Below is a quick reference for 4xiDraw V1 / A4 / A3 / XL / XLX.


First of all, Drawing Machine 4xiDraw V1 is plug-in-play method, and when power is plugged into the plug, it is in standby mode at the same time.

4xiDraw V1 complies with the GRBL protocol.


The connection method to the controller for GRBL can be connected using Bluetooth.


Therefore, you should prepare a PC or notebook that can be Bluetooth-enabled. The Bluetooth name is “4xiDraw-V1-XXXXXX” and the password is “1234”.


Check the connection status of Bluetooth and check the set serial port. Download the GRBL Controller.


When connecting with Universal Gcode Sender or LaserGRBL, you can connect to the serial port identified.


When you start the connection, you need to enter $ H in the command line or click the Homing button to set the X and Y axis coordinates to 0,0 for Origin setting.

It is always preferable to set the homing at the start of drawing.


In 4xiDraw V1, the main frame is the Y axis, and the load on which the pen is installed is the X axis.


It is important to keep it as horizontal as possible because the height of the X-axis rod can vary depending on the distance of the X-axis rod when drawing.


Please keep your drawing machine and paper stationary so that you do not move when drawing.


Below are the default GRBL settings that can be checked by entering $$ in the command line.

$121=500.000 (Y-axis acceleration)
$122=10.000 (Z-axis acceleration) Not used in 4xiDraw V1
$130=290.000 (X-axis maximum travel) A4: 230mm, A3: 290mm, XL: 230mm, XLX: 300mm
$131=430.000 (Y-axis maximum travel) A4: 300mm, A3: 430mm, XL: 600mm, XLX: 600mm
$132=20.000 (Z-axis maximum travel) Not used in 4xiDraw V1


By default 4xiDraw V1 does not use the Z axis. Instead, you can use a servo motor to adjust the angle to adjust the height of the pen. (* If you want to use the Z axis, you need to replace the pen header and add a step motor driver to connect.)

The height of the pen holder can be lowered or raised by adjusting the angle of the servo horn using the following command. Please refer to it when writing G-Code.

Pen Up/Down servo control command

Pen Up
M3 S0 The height of the pen can be adjusted by changing the angle (S).

Pen Down
M3 S90 The pen is basically pressed down by a spring.

* If the downward pressure is weak, you can use an auxiliary device to adjust the angle of the server. (Requires additional parts) Caution: If you forcefully set the servo angle and press the pen holder, the servo motor may be damaged.

The power supply of 4xiDraw V1 is DC 9V/2A(18W) as standard.
However, the operating power range of 4xiDraw V1 can be used up to ~12V.

The XY motion speed of 4xiDraw V1 can run at ~15000mm/min, but usually 5000mm/min or less than 10000mm/min is recommended.
If you want to drive at high speed or if freezes occur frequently during operation, we recommend that you use an adapter or power supply (PSU) with a DC 12V/3A or higher power supply.
