Hello - I have built the K8600 and most went smoothly - however the USB connector [type B] is mounted perpendicular on the motherboard.
If one wants to connect a USB cable - bending the cable will not be possible as there is not enough distance to do so and this part of the cable is also too rigid.
I hope I missed something … and Velleman has not overlooked a design issue forcing the user to leave the bottom plate open - even then the cable will obstruct. Also the related chapter 6 [Using the printer] is not filled in … - so a photo is not available to clarify this issue connecting the USB cable with the printer … It is a pitty that the USB connector is not accessible from the outside …
Thanks for all technical feedback !
