Original shorting out

[jack-wadelin 0]

Hey guys,

I've fired up my original ultimaker for the first time in a few months and its begun to have problems.

When I run the autohome function it moves fine and does everything's as its supposed too. however when I try to print/ use the bed leveling system, it seems to have problems with its power.

The screen goes darker, and the machine wont operate, however every 2 or 3 seconds it suddenly flashes up (I'm guessing it builds a charge up) and the machine will operate, however it only lasts a second and then returns to becoming dark.

because of this the scale seems to go down and the print doesn't get a clear feed as both the nozzle wont move or the extrusion gear.

Any help would be great thanks

Jack.
