    24v psu ideas.

    Yeah, I'll admit I read the thread a bit hastily. I just assumed that he wanted to use the higher voltage for the board as well as using the same voltage isn't much of a change :)

    I was also unclear about the 7812 not being able to handle 24V, I should've clarified that I meant without additional heatsinking.

    I need to stop bouncing between tabs and reading different things while replying to topics :p

     

    Haha guilty of that too sometimes. :D

     

    I am planning to do the exact same thing with my machine so also curious if nobody has input to why it wouldn't work...

    Seems like people are generally misinterpreting your intentions though...

    The way I understand you (and the same way I was planning to do it) is like this:

    - Buy a 24V PSU large enough to handle both printer and HB (I think 150W might be too small, I got a 350W myself)

    - Connect the HB directly to this PSU through a relay controlled by the HB outputs on the UM board

    - Connect the UM board to the PSU through a DC to DC converter that regulates down to 19V

    So HB gets 24, UM board 19 and you don't need to change anything on the board itself

     

    Exactly the way I was thinking but without the relay. I was going to unsolder the Mosfet, take a wire from the gate pin to the mosfet thats on a external board that then allows you to use the 24V with the loveliness of PWM! Also gets rid of that ticking from a relay!

    I have a brain fart of an idea on how go use a 24v psu with a ultimaker. I though that using the full 24v for a heated bed then using a dc to dc converter to get to the 19v for the rest of the electronics. Anyone see any issues with this idea? I have found a few 150w dc to dc converters on eBay so seems it will have enough juice.

    Cura 14.01 Mac Error

    in UltiMaker Cura

    Just downloaded Cura 14.01 for the first time on my Mac running Mavericks. I keep getting an error saying Cura: Cura Error. With two options: View Console or Terminate. The Console has nothing apart from Cura: Cura Error in it. Downloaded 13.12 and thats the same too. What could be the issue?
