3D printer calibration test STLs?

Is there any well-known test set of 3D models that I can print out which will clearly show up the problems I need to work out in calibrating my 3D printer? Ideally, it would be either one or multiple models which shows the point at which overhanging…

Can I increase retraction length on an E3D v6 beyond 2 mm if I have a really long Bowden tube?

E3D mentions on their own wiki: Excessively long retractions will cause issues by dragging soft filament into cold areas. [...] for bowden systems you might want to go up to 2 mm. Retraction beyond 2 mm is likely to cause issues. I have retraction…

How does acetone "rejuvenate" PEI?

The Prusa3d knowledge base mentions that acetone will "rejuvenate" PEI in addition to cleaning oil and grease from the surface. About once a week, or when prints stop sticking, use ACETONE to clean the bed. It removes grease better than IPA or…

Handling retraction when using a mixing extruder (2 in 1 out)

I have a Zonestar Z5FM2 running Marlin 1.1.8 with a mixing extruder. That is, 2 extruder stepper motors feeding a 2-in 1-out hotend (similar to the E3D cyclops). I'm slicing with Simplify3D and I have set up: T0 set to the first extruder; T1 set…

Ender 3 severe under-extrusion

I've been using my Ender 3 for about four months now and it's been working wonderfully. The print quality is amazing and all the prints are very strong. Then about three weeks ago, my entire system crashed while Ultimaker Cura was open and it lost…

Question about retraction distance and stringing/print quality with PETG

I've tried printing the Basic Stringing Test on my CR-10S using PETG (250 °C nozzle, 80 °C bed) with different retraction distances leaving all the rest unchanged. In the image below you can see 0 mm, 5 mm and 10 mm retractions (in order…

Is 3D printing a good way to save money?

If you already have a 3D printer, would you say that you have saved money on buying the printer, buying models and then printing the models, compared to buying something alike in retail? Would you say that saving money is an argument to buy a 3D…

Calibrating E steps for new filament

Is it a good idea or do I need to calibrate my E steps after I switch to a new filament due to the different types I use (to make my prints accurate)? E.g. calibrate when switching from PLA to ABS/PETG?
