Risks and challenges

All shipping routes are confirmed. 
Suppliers and manufacturers are informed and ready. 
There are only a few small adjustments to the software. This will be fixed shortly.

The Development continues running. 
Extensions are planned for the near Future. 
Upgrades like an LCD display with SD Card reader and much more.

It will be followed by other multi function heads. e.g. a plotter head.

Furthermore, we are currently planning a upgrade module of the laser. A laser with a 2W diode can be purchased in the future.
