finally getting back to working on this. and, after frying a brand new power supply from e3d, I decided enough was enough... [img] 700W ATX...
Worth it. All the fun sexy materials like carbon fibre, conductive abs, nylon etc need higher temps. Worth the high price to get this carriage...
Oooh! This is great news! Now its tricky, I'm saving for my holidays in September, but I'm gonna need to order some of that and a new psu. The...
Quick question regarding the Protopasta High Temp PLA. As many of you will know, I've been having an ongoing battle with my printer to ultimately...
i think the fuse is now blown anyway, so I cant check anything else for a few days till i get a replacement one. Time to look at power resistors...

I thought as much. Resistance is still reading at 0.9R, so I'm swapping out all the wires from the PSU to the board. comparison of old wire to...
Finally getting a chance to work on this later. Quick question, if, when I disconnect the heater and check the resistance between the two wires,...
ok, so just so i'm 100% clear, it was the wire going from +VE on the PSU to HB-PWR+ on the Rumba that freaked out and caught fire. there's 2 power...
Is that the most likely cause of the problem? Is there any other things I should check? Especially as the bed was working fine till now. It was...
