Adding more parts to the machine, lights and other.HP Persson
The K40 machines differs a lot in what parts and function is has added, some has extra lights, laser dots and different parts already fitted, others are bare lasers.
These machines are already on the edge of what the power supply can handle, adding more load to it may create problems.
To solve this, we suggest that everything you add to the machine is connected trough a own power supply or smaller wall plug with correct voltage.
Doing this you can rule out all problems occurring in the machine to your added peripherals and make sure whatever it is, it isn´t because of your added parts.
