Nozzle and Cleaning Tool Recommendations
Does anyone have recommendations for spare nozzles or those for abrasive materials. Also, any nozzle cleaning tools? Amazon is best and I've seen the small drill bits and replacement nozzles but not sure if someone has experience with better quality of specific ones.
Thanks
Re: Nozzle and Cleaning Tool Recommendations
it's always worthwhile having a spare nozzle. brass o.4 is a good first spare.
if you are going to print abrasive filament, a hardened 0.4 nozzle is a good starting point.
I have never needed to clean out the actual nozzle on the prusa either as the original mk1 version or the mk2 version...
I did have a problem in the cold end that I cleaned out with a 1.5mm drill after removing the nozzle.
the tiny drills have a couple of issues...
1, being a drill, it's likely yo remove some of the metal as it works, making the hole bigger,
2, tungsten carbide is incredibly brittle, the drills are likely to break off in the nozzle and make it even more difficult to clear.
if you are having nozzle blockages at 0.4mm, then smaller nozzles are probably not a good idea.
larger nozzles have some uses, but the i3Mk2 may be limited in it's ability to melt sufficient plastic to make best use of the larger nozzle.

Re: Nozzle and Cleaning Tool Recommendations
:idea:here some advice for "tools" you usually won't think about:
🙄 some people here (like me too) use guitar strings to clean either the nozzle upwards (from the bottom), or the heatbreak / ptfe tubing downwards (from the top of the extruder), if something got stuck inside the heatbreak or the nozzle.
➡ to clean the nozzle from below, a 0.13 or better 0.15 string is perfect.
➡ to clean the tubing (including the heatbreak), from the top of the extruder, a big string (0.56 or 0.70) like this one might be very useful. just heat up the hotend and insert the string instead of the filament and push & pull with the string through the tubing. the molten remainders of old filament will stuck at the windings outside of the string and you can pull them out safely. if you can't remove the remainders from the string itself, just cut off the used end with some strong end-cutting pliers and repeat the procedure.

Nice tip. Never heard of that 😀
Can the string damage the PFTE tubing?

🙄 in my mind: at least not with the mentioned method.
