Vertex K8400 random connection loses while printing

Hey, I’ve been wondering if it is common for the Vertex K8400 to loose connection with the Pc while printing wich causes it to stop and ruin the print by burning it . Maybe you guys know how to prevent it . Thanks

Dead simple use a SD card =)

I know but since I don’t own one I’d had to purchase one and to be honest I prefer using my vertex via my pc. Fortunately it dosent happen as frequently as it did before I connected the printer directly to the Pc instead of connecting it to a very handy USB port in my keyboard.

Dies your pc go in sleepmodus? Or mabey because the screensavers jumps in… I disabeld all of these options and did not have any problems with it. But i do prefere sd card.

Hi Matt,

you have to make sure that you just use a short USB cable, I got the same problem with K8200.

I have a very cable from the controlboard connected to a USB hub, from there you can use long cables,

no problem since then.

Unfortunately I checked and it’s not the reason since it happened in front of my eyes while I was watching the prints progress I also unchecked the option that turns off unused devices. Also tried reinstalling the USB drivers , still happens every now and then . Really wierd

I’ll definitely try, thank you for your advice

Be sure that Repetier is the only program running, deactivate antivirus,skype,teamviewer etc. Try also to change the usb cable,taking this the shortest possible. Have fun

Yea that may work, thank you

Hey matt,

What mine used to do is overheat the power source and thats why it stopped. The problem I had with computer connection was related to the COM port and the repetier software but now everything is fine using Cura. Check if it is any of this problems that I listed and let me know if you need anything else.

I would add…K8400 does not come with heatsinks on drivers, i just put a complete set,now it goes smoother on longer prints
