Connecting USB Cable to motherboard K8600


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 !




This is chosen on purpose.
The USB is only there for updating the firmware.
As stated in the specifications( communication: an SD card for direct printing and a USB connection for updates )
It’s placed in such way you can’t use it while printing.

Best Regards


I wonder why the Nano is made so that one can’t print through the USB? In Vertex it works very well and is much more practical than fiddling with the S-cards.
Also, why did the Repetier Host for Nano install something like Repetier Server? The Nano dosn’t seem to have Network connection either.


The repetier server is something from repetier their self. You can perfectly uninstall the server you don’t need it.


You can buy a 90degree usb-90 degree angle connector and then let the usb-cable go through the same hole in the back as the cables for the hotend.

Today I have printed from an raspberry pi using good old pronterface with no problems. Prints both from a file loaded into pronterface and from the sd-card in the nano.

Next is to use octoprint as host and simplify3d as slicer. (one slicer and one interface for all my (3) printers)

Have fun


Did you have any luck to connect the octoprint?
