Rbox-01 unit, over 5 years old but looked after, not thrashed. Strange fault in that bedplate heats up ok and temp is reflected in on screen gauge. Heating continues until filament heaters turn on, around 62c, on which the bed heating then struggles and starts to loose heat. AM software now struggles to keep up and gets stuck in a cycle of waiting for the bed to heat to 70c but will never get there. Meanwhile, filament purge then fails with no output at which point everything comes to a halt.
Now, it initially looks as though the PSU is managing to supply enough power to the bed heater, although not very fast to target, but then just totally gives up the ghost when asked to run the bed and the filament unit. Thermostat is relaying temps back to the AM software, the numbers are there, but it is almost as if the PSU cannot provide enough power. Attempted a purge of the head and that just fell over as well, no extrusion and heat not getting anywhere as hot as it should.
Anybody else seen this sort of thing, and a cure before it's back to CEL for a look?
