AFter changing the controller, My bed will only heat for about 45 seconds and then it errors out. I can reset the board, and then get another 45 seconds. I repeat this until i get to my desired goal. Not sure what has changed.
First, what is the error?Marlin has a timeout to prevent thermal runaway. Did you edit/load the firmware? If so, look in the configuration.h and configuration_adv.h to see what your value are set to.
I am using the stock firmware from Gdrive. I read on another forum that utilizing a separate mosfet between the PSU, the board and the heated bed would work so I purchased it and it works great now. Sorry for not replying that it was resolved sooner. And the error was the thermal runaway for anyone else that might need help with this same issue.
