Heated Bed Issues

Recommended Posts

Hi there,

we have once again issues with our heated bed. We use a 100k thermistor to measure its temperature and get the max-temp-triggered-error every time. To eliminate soldering problems we connected the thermistor directly to the board, still receiving the same error. Are there any glitches concerning the firmware?

many thanks and best regards

edit: funnily enough we changed the firmware setting to epcos 100k with the result that we measure 0 degrees constantly and always get 19V output at the heated bed connector.

Ok, that one was a bit outdated. I just updated it, it could have contained a bug in the bed temperature (There was a bug caused by one of my updates)

I tested the bed heating today, and it works in the version you can build now.

1.5.3? I've never seen one of those, but I think it should work, the firmware should support the whole 1.5.x range. But the lowest I've tested is 1.5.4 but there can always be a bug somewhere in the code. I currently do not have the facilities to test themistor settings.

    • "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.
