I came back to a print that failed pretty nastily, so I stopped it/cleaned up the plate and thought nothing more of it. Later on I tried to heat up the printer again but after a minute or two the LCD died and wouldn’t turn on. I traced that problem down to a blown F3 resistor on the RAMBo and swapped it out with the F2 (which I believe just used for the motors) while I wait for more to be delivered - now it all powers on fine (with them swapped).
I noticed when I was looking at the heating-block that it looks like there’s PLA inside and to make things worse the hot-end/resistor is not heating up now . As far as I can see nowhere in the UK seems to sell the resistor - though tbh I’m not 100% sure what I’m looking.
So firstly - is there a chance that a failed print caused the heat-resistor to fail which in turn caused a fuse to blow on the RAMBo?
Anyone know anywhere in the UK/EU (ideally in London that’s open tomorrow ) that sells the heat-resistors? If not I’m tempted by something like (http://www.aliexpress.com/item/Heat-Resistor-4-7-Ohm-suit-for-Budaschnozzle-v2-3D-printer-sprinkler-head/1995934327.html) - might not be the best quality thing but it seems the most simplest and fastest way to get a replacement.
Any help is appreciated.
