Center your Plotter to your starting point according to the size of the picture and reset all your X-Y-Z Axes.ġ3. I will put 1 sample gcode file for you.ġ2. If everything is okay, call your gcode file from the Browse section of the Gcode Universal Sender program. If your connection is ok, you can move your plotter motors in X-Y positions with the direction keys.ġ1. Motor step number, motor step rating, gear diameter and teeth can be important in many printers.ġ0. If necessary, you can get help from this link for calibration according to the motor type you have used. Open the Gcode Universal Sender program and connect to your Arduino UNO board.ĩ. Create a sample 4 cm x 4cm square area and import a picture into it or draw a picture Save your created file from the Save a copy to section with makerBot Unicorn G-code (.gcode) format.Ĩ. Copy the Inkscape unicorn gcode extension to the extentions folder of the Inkscape program and Open the program.ħ. Install the InkScape program on your computer.Ħ. Now, connect the plotter you have made as hardware to your computer by cable.ĥ. After installing the GRBL software, install it on the Arduino Uno board. Open the GRBL software v1.1h file and upload it to the arduino to the hardware part.ģ. Install the Arduino software on your computerĢ. Also CNC Shield for 28BYJ-48 Small step motor driver board I used the 5 volt outlet on it.ġ.

I used the output on the 3.3 volt CNC Shield for the Pen Holder Drawing Page lighting led. Socket locations on CNC Shield for Homings Switches are clear.Also show you in the photos. You can also use them disabled.Or by adjusting the settings. The second reason is not to cut the stepper motor socket. Because 28BYJ-48 Small stepper motor works with 5 volts. 28BYJ-48 motor driver circuit extra has two reasons. Because the CNC Shield is controlled by 12 volts, the Z-axis A4988 driver can cause some small motors to overheat. I positioned the 28BYJ-48 Small step motor driver and its circuit to the pen holder motor output. There is a CNC Shield on the Arduino board and 3 A4988 motor controllers. I did not specify Plotter connection and circuit diagram especially. I used to upload this file to Arduino GRBL v1.1h () Release
