been doing some testing, as below. same filament, 220 C Nozzle, 60 C bed but first with 0.4 Nozzle and second with 0.25 Nozzle
I wonder if lowering the print speed might also have helped with the 0.4mm.... Some of those jagged edges could be a result of a big fat nozzle (in comparison to the part) moving quickly. Smaller nozzle works well as a solution too.
I have been doing that now with the 0.25, down to 50%, the cogs shown above where both at 100% though
Printed out more parts, all with 0.25mm Nozzle, only a couple of parts left now, just waiting for some M2 bolts and drill bits to start assembly
All three gears are printed with samples of metalic filament from Faberdashery, the light Brown is what they call "Bling Bling Gold".
Well mostly assembled now, just tuning the gears etc. but looking good.. Got to do the hands in a different colour though.
