Hi,
before I'm gonna open the Ultimaker 2. What is the problem with the Ultimaker 2?
- Ultimaker was printing with heated bed but a second print the heated bed was cold.
- With the second print the sensor stated: 90C/60C but with an cold bed
- Now when I turned off the Ultimaker 2 for a while the sensor stated in the Maintenance/Advanced/Heatup Buildplate: 85C/0C and still the bed is cold.
What is the issue in my case?
