Checklist when you get your printer

Updated: Jul 15, 2020

- Motors plugged into the controller at the back. Controller motors are in the order X, Y, Z. X = wiper (future), Y = automated projector, Z = build plate. Never remove or insert plugs when controller has power.

- Fans plugged into the top connectors of the controller.

- Microswitches plugged into the the controller. They are in the order of X, Y, Z. The newest version of Gizmetor will have a button to test the microswitches. Until then you can download and connect to the printer at a speed of 9600 baud. Send the command M119. If the rail is touching the microswitch it should say triggered. If it isn't touching it should say open.

- Wires are plugged into the microswitches. Far left and far right. Nothing in the middle.

- Z microswitch is about 60mm above the bearing bracket.

- Front projector bracket is level. Forklifts have been having a lot of fun with some of the printers.

Connect to printer

- Plug your PC into the printer using the USB cable.

- Start Gizmetor.

- Go to the calibration tab. The "Printer USB Port" drop down should have a comm port in the list if you plugged in the USB cable into the printer and your PC.

- Select a comm port, usually not COM1, click on Connect. Gizmetor will try to connect on the comm port. If it doesn't connect, try another one in the list. If it still doesn't connect it means Windows didn't automatically install the driver. You will then need to install Arduino so that the driver can be installed.

If the PC didn't connect to the printer

- Close Gizmetor and all Java windows.

- Download and install the Arduino software from After installing the Arduino software your PC should have the drivers. Try to connect again using Gizmetor.
