  1. Just to kill this one. I replaced the board after buying a new one. This burnt out again after about 6 months. I was given a new one free of charge but bought a new power supply. So far so good. Been in about 6 months so if it is going to go again it will go soon. I am not expecting it to burn out again.
  2. Hi. I have been looking for an easy way to get a bitmap traced and then use that traced outline as part of a design in Inventor Pro. In this way we can extrude images such as the outline of a bulldog to include in a design for a speaker mesh / guard. I have yet to find a way to do this easily that students could use. Anyone got any ideas? Thanks.
  3. Yes it looks like that would add up. They were both authentic boards. Do you think that due to the fact that the elevated voltage is not that much higher than the max rating it would have basically burnt out over time. This would explain why it worked fine out of the box and for a period of months after the new board was installed. So basically the power pack could have had a fault from the start or it could have developed a fault after the warranty ran out. I think that the second board did not last as long as the first so I suppose it could have gone later on in the life of the printer rathe
  4. The first board burnt out not long after the warranty period ran out. The machine was being used in a school where it was active for part of the year then unused for quite a few months. We have two machines running in the same room. The same one has blown again on exactly the same chip. But the other is fine. In the same room over the last 8 years or so we have been running a cnc router, a cnc engraving machine, a Replicator 2 (last three years or so) along with two computers. This is the only machine that has had a problem. I have been offered a replacement board by my reseller. Which in i
  5. Hi. I have replaced the main board in one of my machines once already and it seems to have blown again. In both boards there is a distinct small hole in the chip U6. Has anyone had any issues like this. The two machines have had relatively little use in relation to what I would expect to cause a board to burn out in a machine that costs what the Ultimaker 2 did. I have been looking for schematics to see if I can find out exactly what this chip does. If I can work this out it may point out where the fault actually is and provide some indication of how to fix it. I have been in touch with the
  6. Ok just ignore that post. I looked in the how to document for the original machine. Removed the cover for the display board and the control wheel and matched up EXP1 and 2 on the display board with the EXP1 and 2 on the main board. Should work I would expect.
  7. Hi. I have to install a new board in one of my machines. Like a good little boy I took a photograph of where all of the wires went before starting. However, for some reason I must have disconnected EXP1 and EXP2 (connections for ribbon cable for display and control wheel) before using my brain. Is there anyone out there that knows how to tell one cable from the other. It may be that they are both low voltage input and out put but I do not want to take the risk of damaging the board so please only advise if you are 100% sure. Thanks.
  8. Took the back off the machine to get at the main board. Clearly it is not a firmware issue as the laptop would not detect the machine when connected up via usb. The board is totally dead with no green led on the board lighting up when the power is switched on. I am not happy. I have had this machine for 18 months. However it has had limited use. It has not been used much this year as we are just hitting the time in the year (used at a school) when we print. I have two Ultimaker 2 machines both purchased at the same time. I also have a Makerbot that is 3 years old and is still buzzing away. I w
  9. Tried to update firmware but laptop does not detect the machine. Looks like its time to get the screwdriver out.
  10. Thanks mate. This seems like a very good first check to perform. I have juggled the power bricks around. A software check would seem a good place to start. If this fails then I am going to get the screwdriver out and start checking each system block at a time.
  11. I think it will be over the year. May be time to get out the screwdriver.
  12. Just dead when switched on the next day after doing a normal print. Have not tried it without the card in but as the screen is also blank I am not sure if this will make a difference. I will still give it a go thanks.
  13. Thanks but that was our first check. No luck.
