Hello,
From one day to another my heatbed connected to my Rambo 1.0e stopped working.
What I tested at the beginning:
- Fuse: ok
- PowerSupply: ok
- Heatbed: ok
- visual inspection of the Rambo: ok
But: LED at heatbed does not light up. Only in the moment of switching on, there is a tiny flash.
So I disconnected the heatbed and figured out the following:
When switching on, the headbed LED flashes shortly (~0.5 seconds) with full brightness (brighter than with connected heatbed) and continues to glow dimmed.
I've attached a picture where you can see that.
I measured the output voltage (still without load) with different heatbed input voltages:
12V: 2.0V
16V: 2.2V
24V: 2.5V
Any ideas what I can try as well/what might be defect?
Thank you!
Kind regards,
Markus
