Thanks for the tips! Actually, I found a 24V/30A PSU from my local hackerspace - that surely has enough power! :D It's totally overkill and quite big too so I'll probably buy a more suitable one later... Maybe I could measure the power consumption somehow and get a better idea on how big PSU I'll actually need...
I bought this heated bed - no power rating but the circuit looks exactly like the one in UM2 so it should be similar. I'm going to use just a single extruder for now - I can then make some upgrades later if I happen to want dual extrusion.
Hmm... I have thought to try printing nylon/acetal sometime as they have some nice properties and are good polymers for mechanics. Mostly I'll print just PLA and such, maybe try ABS sometime, so I'll probably leave the 40W heater for now. Safety is my number one priority so better not get carried away with too much power... :D
And for this post not to be totally off topic, I did buy those XY steppers (17HM19-2004S) from stepperonline and for the extruder a JK42HS34-1334 from ebay. Had to look closely because they also sell JK42HS34-1334A steppers on ebay and those are not the same: a bit more torque but also more resistance and inductance etc. The -A version seems better to me.
