I've just got a self built prusa (more or less) working. I've decided to dismantle the Huxley that I got from TechZoneCom as I could never get it working due to bad/missing/melting parts. Just going to use the hardware to produce some other things like spool reel, etc. I was initially intending to print out replacement parts, but after building a prusa and seeing how much simpler it is, I changby darrenp - Huxley
Fantastic, that worked a treat. The MOSFET is still getting rather hot, but at least it isn't melting. I've also had to get a new power supply, the one I was using wasn't enough to drive the steppers, hotend, and bed! Getting some nice quality prints now. Time to try something big!by darrenp - Sanguino(lolu)
Thanks for that. Is it just a straight swap? I'll get some ordered from RS and give it a try. Is it worth swapping the hotend one too? Its been a looong time since I did any major electronics! Whilst I'm here, fantastic blog. Been reading it for a few months now, very handy! I'm not that far away from you actually, just in Lancaster. Cheers, Darren.by darrenp - Sanguino(lolu)
Hi people, I've finally got a working printer, and getting some good prints off in ABS, as long as they're small. Larger prints are warping badly. Obviously I need a heated bed. I've got a MK II PCB heated bed, but when I've hooked it up the bed mosfet unfortunately melted. After this I measured the resistance of the bed to be a little over 1.5 ohm, so sounds like a lot of current going throughby darrenp - Sanguino(lolu)
