UMO with HBK: Heated bed causes resets.

Recommended Posts

I recently upgraded my old Ultimaker Original with a heated bed kit.

Everything works, but heating / controlling the bed causes random resets. When the bed temperature is set to 0, everything prints fine.

Just setting the bed at 60° and not printing will not cause resets, but when the bed is controlled during a print, it resets frequently, but randomly. Could be 5 minutes, could be 30 minutes.

I suspect switching the bed on/off causes some power fluctuations . Currently don't have a scope to verify this this.

Checked all the wiring to make sure it's not a short or loose wire somewhere.

Anybody seen this before? Any ideas how it could be resolved? Like putting a big capacitor across the heated bed connector, for example.

- Electronics 1.5.3 with upgraded arduino mega256 board

- Ful graphic smart controller

- Marlin 16.04.1

I'd check the label on each power supply brick and see what each is rated for.

On my heated bed upgrade to my UMO, I really had to screw down hard on the terminals to make a good connection. When I was reading your post, I was thinking you might have had the same issue I had. But if you have a weak power supply, that'll cause problems!

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
