Congrats,
sometimes the obviously things we oversee 
As a few members say, the printer is great, when running.
Had to swap a few parts myself, provided by bellman, so I know how frustrating it is, not to get it run…
I made some mods to the printer and at the moment I print PVA and FlexiSmart with success…
But I was on the same level to throw it away…
Have fun and cross fingers for you
Best
Frank
Lukeatkin,
Glad to hear it’s getting better.
Now I kind of feel like an idiot.
Normally check the output voltage of the power supply is one of the first things I suggest but failed to do it this time.
Most people seem to be put off when I bring it up.
I also forgot there is an adjustment for the power supply on the K8400.
spoke too soon 
failed constantly today, all same errors as above, i kinda wish velleman would respond to their emails!
Hi Luke,
Could you post some high-res pictures of the printer?
Were you in the same room when the printer failed?
Best Regards,

What would you like in high res so I know what sections to shoot,
I have been in the room pretty much every time it resets,
It’s litterally like someone’s hit the reset switch as comes up with vertex logo and hangs,
Odd as the main reset I have unplugged to eliminate it from being the problem
Could you post pics of the LCD, X-Y Carriage and the mainboard?
Also is your mains socket is properly grounded?
We suspect you have a build up of static electricity.
Best Regards,

[quote=“Lukeatkin”]Odd as the main reset I have unplugged to eliminate it from being the problem[/quote]This still leaves the reset on the LCD than can be pressed by the acrylic panel. Did you check if it’s perfectly free in it’s hole?
hope these are of any use, i have no high res camera here, so did the best i could
mains is correctly grounded, and tested, brand new house, electrics are all new and certificated, checked them again incas and checked grounding continuity to PSU from plug, all fine
Yup… Checked belts for rubbing, random reset after 4 hours of printing,
Alas same issue, random reset, nothing on log
Couple more thoughts.
Have you tried to reload the firmware?
Have you made sure the pins for the LCD display are not loose?
Also I know you don’t want to print with a computer.
However the larger SD cards have been known to have issues with the Raspberry Pi.
I am wondering it either the pins that touch the SD card have a problem or if they are disconnecting from the vibration from the printer.
Printing from a computer may point you in the right direction.
Like I said these are just thoughts.
Hey guys, printer has been sent to ESR so with a bit of luck they will find the fault, with the resourses they have I’m hoping they will isolate the problem and sort it
Was hoping to get it sorted, now having to hang tight to see what the result is

Please let us know what they found. I’m having exactly the same problem!
I recently had a similar problem too, it cames from the wires loom going from the printhead to the motherboard : they were broken inside !!! Not easy to find out but by repairing it I’ve discovered the wires are very fragile inside… As a solution I’ve made my own loom and now I’ve no stop problems at all anymore !
they’ve had the printer two weeks now,… no fault found, i may be losing my mind a touch
I had exactly the same problem. The printer was sharing a multi socket extension cord with my computer and other devices. I moved it to another room and plugged it directly into the AC wall socket. I haven’t had any resets since then. I’m not using a UPS or net filter.
got the machine back from ESR!
its working flawlessly! no idea what has been done but from the emails they did a small bit of setting up and its sorted :S
scrap that just faulted same random reset is also running on UPS now too which i bought directly for this printer
