  1. I am trying to update the firmware on my OUM to support a heated bed, however, everytime I try to upload my custom HEX from robotfuzz it times out. I am able to load the default firmware without an issue though...

    I have tried Cura 15 and 12, as well as Windows and Linux.

    It does seem to erase the firmware (as it will not post if you un-power it before reloading the default).

    Ideas?

    When I run Cura from Linux I get a warning about the serial port not being valid (I can grab the full message if that helps)...

    Is it possible the generated HEX is invalid?

  2. Alright... So I have the custom HEX file, but when I try to load it, it times out before loading any data. It leaves the controller in a locked state.

    If I then try the default firmware it loads fine.

    Am I missing something? The firmware is 281k.

  3. I am in the process of installing a custom heated bed and am having a few problems.

    I have installed a 4.7k Ohm resistor in R4, but am getting a MAXTEMP BED error. The temperature is changing, but is reading incorrectly (change is revered, temp goes down from 999 as it is heated).

    Also, then I turn off the heated bed, I get some sort of spike in the system and the controller freaks out.

    Ideas? I have h

    Here is a video of basically what I just said:

     

    Here is an extremely similar heated bed suggesting the 4.7k Ohm resistor:
