In my experience and oppinion the mainboard needs an update, for example resettable fuses. And the mainboard could be cheaper also why does it cost 200 euro? When i look at for example
GT2560 from Geeetech. They have resettable fuses and the board costs arround 45 euro’s. And the quality of the K8400 mainboard is not high let alone worth 200 euro’s. But i have to say
overall the engineers of Velleman did a nice job and they can be proud of there design. I am curius what the next verson will be.
Where did you buy this board for 200 euro and why did you buy it?
If there was an issue with the board, you could have returned it for inspection/repair/exchange.
Although our distributors are free to determine an end-user price, 200 euro seems a bit high.
The distrelec link is the mainboard for k8200 and not for the vertex. 1500 NOK at the multisupply site is pure robbery even thow it is interesting that they provide it 
Is to bad that there dont exist a site that provide all the parts for the printer. Waranty is one thing but i gues sometimes when you want to do something and only want surtain parts or need something that isnt covered under waranty it becomes a problem.
I have been in touch with Distrelec in Switzerland about this and they have now corrected the incorrect IMAGE shown on their webpage.
Hope this helps any potential buyers.
Success.
