You have to supply more information.

Is your toolhead detected on the touchscreen (green dot)?  
The other toolheads are also not working?  
In this case I think your controller causes the fault.

Did you insert the toolhead cable the wrong direction once?

Its possible to reroot the tool port to another port of the controller (this does only work for 3dp toolhead):

How to use:

> [@A350 3D module not detected, even after new purchase of module](https://forum.snapmaker.com/t/a350-3d-module-not-detected-even-after-new-purchase-of-module/30007/19):

> Ah, stupid me, did not read the doc properly. If you go to the page I linked earlier, it is pretty clear. Here’s how it really goes: Start Luban, connect to printer Switch to the “Workspace” section of Luban In the Console section where there’s “Send command”, type M1029 E2 (case matters, captial M, capital E) and hit enter Send M500 command to save setting Power-cycle the machine → Now the setting should stick and the port re-mapping is effective. It will stay until you repeat the procedure…

If you have ever plugged or unplugged a module without turning the printer on and off, that can damage the controller as well.
