Topic: realisticly attaineble resolution

What are you all getting as the best real world resolution out of Doodle 3?

I have some part assemblies to design and print; so i am trying to figure out the minimum clearance i have to leave between parts for them not to stick together. Is 1mm separation realistic?

I am still fighting backlash; Just trying to figure out best attainable results people are getting...

Thanks ahead.

Re: realisticly attaineble resolution

Depends how well your printer has been calibrated. Best thing to do is do a test and try it out for yourself. Everyone has been calibrating their own printers to different degrees so there isnt much of a standard. Just put a bunch of shapes next to each other at different distances to figure out which works best for your printer. I'd probably use a bunch of cylinders since perfect circles are the hardest things to print.

A lot depends on your settings of course, like MeshMoth was saying, but I have gotten some Emmett Gear Bearings to print with something like .2mm or less separation between the planets.  However, the base layer was fused since I have a bit too much smooshing on my z-tab setting. 

Some tips:
-Go with < 50 mm/s outer perimeter speed
-Do all calibration steps for extrusion and backlash (including perfect circle procedure)
-Check your filament diameter periodically
