If you turn on the machine, and the Touchscreen displays the lower-left screen (as opposed to the lower-right screen), then it might be that the 3D Printing Module is not detected by the machine.
- The toolhead cable is broken.
- The Linear Module or the Controller is broken.
- The 3D Printing Module is broken
1. Replace the current toolhead cable with one of the interchangeable cables (see picture below). Use it to connect the machine to your computer. In the Luban console, input M1999 and see if it displays 3D PRINT Module in the second line from the bottom.
- If it does, then it means the 3D Printing Module is detected. The toolhead cable is broken. Replacing a new toolhead cable can solve the issue.
- If it doesn't, then it means the 3D Printing Module isn't detected. In that case, try the next step.
2. Remove all the cables of the Linear Modules from the Controller, and see if the 3D Printing Module, Laser Module, and CNC Module can be detected.
-If yes, then it means one or more Linear Modules are disrupting Controller Network Area (CAN) communication. Reconnect cables of each Linear Module one by one to the Controller, and identify which Linear Module(s) is broken.
- If no, then the Controller itself might be broken, replacing it might solve the problem.
3. If the Laser Module and CNC Module can be detected by the Controller, but the Printing Module can't, then the Printing Module itself might be broken, replacing it might solve the problem.
