Firmware Trouble UM1


Recommended Posts

Posted · Firmware Trouble UM1

Hi, tried added a heated bed and used the cura standard firmware witch bricked the board. found a guide and tock the board out and flashed with marlin firmware.

Now I have a problem while printing it starts to print funny all over the place with a few clunks :( the heated bed did not work so even tried the standard marlin firmware with no luck. it seems like it happens when the fan speeds up./??

    I think we need more information. What do you mean by "all over the place with a few clunks"?

    Also, the firmware included in cura which has the option for a heated bed is not intended for heated beds you build yourself so that will not work correctly. You'll need to build your own version of the firmware that has the settings you need for your particular heated bed setup. There's an automated builder here:

    It will print fine then start doing radom lines all over, I think iv fixed I did not have the bottom fan fitted and refitted that seems to be working with the standard firmware

    I learnt the hard way that curas heated bed firmware was no good for diy heat beds. I used the link provided and picked the right dropdowns for my setup. but I couldn't get the relay to click when wired up.

    I used the heated bed wiki and wired it up to that but no luck. the firmware seemed to work and wanted to wait for the bed to heat up but with no power to the board it would not heat up.
