No matter which toolhead is connected to the machine, the Touchscreen displays as in the picture below. The machine is not recognizing any of them.
Possible Causes
- The Toolhead Cable is broken.
- The Controller is malfunctioning.
- One or more malfunctioning modules are affecting the Controller Network Area (CAN) communication.
Actions
1. Replace the current Toolhead cable with one of the interchangeable cables (see picture below). See if this solves the problem. If not, go to step 2.
2. Turn off the machine and unplug all the cables (except for the ones for the Power Module and Touchscreen) from the Controller.
3. Connect one of the three toolheads to the machine and turn on the machine. See if the machine can detect the toolhead connected and works properly.
- If not, turn off the machine and plug in another toolhead. Repeat step 3 until you have tested all of the three toolheads. If the machine still cannot detect any of the toolheads, then the toolhead port of the Controller is possibly damaged.
In this case, try to use addon-1 port to verify whether the toolhead port of the Controller is damaged.
(1) Connect your machine to Luban via the serial port using a USB cable.
(2) Then, enter these two commands separately. The M1029 E2 command is used to remap the Toolhead port to the Addon-1 port, and the M500 command is used to save the setting.

M500
(3) After the settings are saved, please turn off the machine, plug the tool head cable into the Addon-1 port, and see if three modules can work properly.
- If yes, then the problem might be with the Linear Modules.
