Accidentally updated firmware. Original Ultimaker with custom heated bed gone wrong

Recommended Posts

Posted · Accidentally updated firmware. Original Ultimaker with custom heated bed gone wrong

Hi everyone,


as mentioned in the title I wiped out the custom firmware. Yay! Now I have uploaded the original one and I cannot understand why everything works fine but the feeder. Too much of it, too quickly.

My printer is the Ultimaker, the very first one. I added a custom heated bed, yrs ago,  using a 100k EPCOS temp probe (+ 4,7k resistor) and a  relay with an external power supply. It has worked perfectly till today.


There was a site, now non-fuctional, where I could customize it. I remember it was a Marlin firmware. I even found a similar site https://bultimaker.bulles.eu/ but I did not manage to find the right firmware for me or something is not correct.


Temperatures (both printing and heated bed) are ok. X, Y, Z are good too but the feeder goes 2x or 3x faster.


Thx everyone for any support
