Yes. FYI this is part of a broader set of problems I'm trying to diagnose on the printer.

I have a Tevo Tornado, it seemingly connects fine, it is recognised by the software and it turns on.
Any command I send over USB is not executed, as if it's not registering them.
I tried on Cura and Pronterface and the printer is unresponsive.
In particular in Pronterface it displays:

```
echo:busy: processing

```

but nothing is executed.
