Still more parts this week, but one of them I can actually do something with!
PCB Heat bed from Reprap source
Aluminium pulleys. These are supposed to give a better quality of print, by having less slop and backlash. A pretty cheap printer upgrade.
A wand-type temperature probe for my (forthcoming) temperature gun.
Hobbed bolt from Arcol.hu.
And finally, and most importantly, the hot end! For my hot end, I decided to go for one from Arcol. It looks like a great design. Things I like about it:
- A super-short heated zone. From what I’ve seen during my research, the Arcol hot-end probably has the shortest heated zone of any hot end. This should greatly reduced extruder force.
- A removable and exchangable nozzle in 0.5mm and 0.35mm sizes.
- An excellent support structure. Unlike most nozzles, it has a fully triangulated structure. This should reduce the movement of the nozzle head during printing, resulting in more accurate prints.
The best thing is that this is the first part that I can actually do something with! I can start assembling it right away.
