Awesome, I will do that and report back. Thanks!

Additional things I have tried:
Re-creating the hex.
Removing all sensors.
Flashing with and without external power.

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?

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.

Oh wow, perfect! Thank you!

Nope, I sure didn't! I just re-updated it with Cura.
Googling that now....
As for the crashing, I have traced that to the relay switch being too close to the controller. No a huge deal as I already have a solid state on the way.

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:
The heated bed I actually got:

That did it! I moved to the next 100k sensor on the list and it loaded right up!
Again, thank you!
