Custom heated bed upgrade for UM1


Recommended Posts

Posted · Custom heated bed upgrade for UM1

Hey, so I designed a custom heated bed upgrade for my UM Original... New Z platform (solid aluminum plate) new flanged linear bearings (similar to official bed kit), and using an MK2B heated bed and glass plate with 3 point mount and wing nuts to level it.

So far so good, works fantastically.

But I'm manually controlling power to the bed right now.

I've heard the reason that UM went with the external control board for the official kit is that the PSU shipped with the UM Original isn't up to the task of powering the heated bed and all other electronics.

Is this the only issue?

The reason I ask is for simplicity, I'd love to just wire the heatbed to the UM control board, and simply replace the PSU with one that's superior. But if there are issues with the control board itself, or it's mosfets, or whatever, then perhaps I should go through building an external control board, or just using an SSR.

Thoughts?

(oh and if anyone wants pics I can post them later).

    A common approach before the heatbed kit has been to drive a relay with the mosfet... The relay is hooked up to the heatbed and a seperate 24V power supply...

    I didn't like the idea of 2 PSUs and all the relays and stuff, 19V is also generally incompatible with alot of reprap parts, and so in the end I decided to swap the board eentirely...

    I now use a RUMBA board running 24V and it drives everything with a ~300W, 24V PSU mounted under the printer...

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
