Frequently Asked Questions
Q: Which CNC machines is this Grbl offline controller board compatible with?
A: This offline controller board is designed for Grbl-based 3-axis CNC machines, including the popular 1610, 2418, 3018, and 3018 Pro engraving and milling machines. It connects directly to standard Grbl control boards used in these models.
Q: Do I need a computer connected while engraving with this offline controller?
A: No — that's the key advantage of this board. Simply load your G-code engraving files onto the included TF card, connect the offline controller to your CNC's Grbl board, and run your project entirely without a PC. You only need a computer to transfer files to the board initially.
Q: How do I load files onto the offline controller board?
A: Connect the controller board to your computer via USB. It will be recognized as a standard USB mass storage device (like a flash drive). You can then drag and drop your G-code files directly onto it. Once loaded, disconnect from the PC and use it standalone with your CNC machine.
Q: How do I switch the interface language between Chinese and English?
A: On the main page of the controller, simply long-press the Z+ button to toggle between Chinese and English. Both languages are fully supported on the display.
Q: Can I manually position the CNC axes using this controller?
A: Yes. The manual control feature allows you to independently adjust the X, Y, and Z axis positions to set your desired engraving start point. You can also manually activate or deactivate the spindle directly from the controller.
