hiya,

I was wondering if any one could help me on this subject.

I use a 0.2mm nozzle and it works well for a while but then all of a sudden it struggles to extrude. and eventually fails.

I printed a fair few parts before it fails but can't figure out why this occurs.

would any one have any understanding as to why it eventually fails. it's a wanhao d4s with a mk10 extruder. it has a ptfe tube liner. I think it's got something to do with it.

I tried to use an extruder unload command for the end code but for some reason it gets stuck and wont unload. normally under those circumstances you extrude a load and then unload the filament but this doesn't work either.

any one got any ideas?

What material? Maybe it is degrading from excessive dwell time.

Maybe too much retract creating clog?

a .2 nozzle is very small. just they smallest spec of anything can clog it. they can be tricky and finicky to print with. have you removed to give it a good cleaning?

In my experience that happens when the extrusion temp is to low, try setting +5°C
