A few days ago I received the kit K8206.
Does anyone know where I can find a construction manual?
One of the folks from Velleman mentioned recently that they had discovered a problem in the K8206 instructions and were going to fix it before posting them. Hopefully the instructions will be available soon.
In the mean time, you may be able to figure most of it out from my stretched K8200 project. The key to building it is to realize that the X-Y table must be turned 90 degrees in the printer frame. This will likely require that you extend or replace some of the wiring harness.

I hope this helps!
Nice work Dr vegetable.
Have Velleman sorted out the issue with instructions and published them. Here we are in February 2016, with the kit seemingly being available but with still with no build instructions?
Come Velleman if you want the people to put their hands in their pocket let’s know what we are getting for our money and what’s involved…
Many thanks, just what I was looking for 
Just a thought.
If you look at the parts included and then look at the instructions you will notice that there is a ribbon cable.
This makes sense since you are extending the bed you will need longer wires.
The instructions do not address this.
