Thank you elocm, but the heatbed was broken in the first 30 Minutes. Replacing the heatbed solved the problem.

I tried PID autotune for heat bed with M303 E-1 C8 S90 //this will run autotune at 90 degrees, for 8 cycles and used S60 for 60 degrees, but also did not reach this in time. There was also the information that 70°C should be reached in less then 3 minutes. Next step will be to replace the heat bed, ...

Thank you Mark, I connected a 750W 12V/62A ATX PSU :twisted: Started with heat bed temperature of 21°C, target 65°, after 20 minutes I was stuck on 60°C I have still the original firmware on board. Is the Repetier-Host able to change the PID-values? Because as said, at the first run it was heating u...

220V, the first thing I checked before mounting PSU.
Is this normal that voltage on PSU is dropping down when bed is heating?

Hi there, I need some help. I assembled my new i3X, and at the first test the heat bed heated up to 65°C in short time. But after 30 Min. while the first testprint, I registered the temp was dropping down to about 55°C. Now the heat bed is warming up to about 50°C, then it takes very long time for e...
