Can you really not burn? I felt exactly the same way. You switch on the machines, the fan is running... but after a while the red light on the left flashes and the other two are green. If you can't fire, check the com interfaces, as this was my next "hurdle".

In fact, there are even two updates to do, one for the laser and one for the frame.

Try updating the firmware first, I had to do it, because mine worked strangely at first.

Do you have the Air Asis. On ? And have you fully opened the air flow wheel on the left frame? This should always be fully open. When switching on, the laser fan and the compressor run for a short time. Then it switches off, which is normal
