3D Printing - whether to buy, what to buy and how to use it?

[Paul_H]

small amount of stringing which tends to remove itself when rail is threaded through

From my limited knowledge its not only the printer that's important but the tweaking of the print software, and in this case using PLA+ filament. I am in the situation of needing the knowledge and inspiration of others

Indeed, learning what all the options do in slicer software is crucial for all forms of 3D printing. Along with recognising and diagnosing faults.

Stringing in FDM can be down to a number of things. There are various test routines and models you can use to dial in the best settings. Retraction, Z hop and acceleration are significant options to look at. https://all3dp.com/2/3d-print-stringing-easy-ways-to-prevent-it/

Filament 'wetness' can be a factor, I've seen increasing problems with 'wet' filament in recent weeks as humidity here in SW Herts has shot up after the relatively dry summer. Running filament through a dryer has helped a lot.
I've also had one reel of filament that was just horrible for stringing, but that might also be due to not having done enough calibration on my last printer (Creality....never again)

Depending on severity, an old stiff tooth brush dry can get rid of fine stringing easily and quickly.
