  • ASA and ABS definitely do better at elevated chamber temps. What temp is enough I can’t say but I still saw improvements when going from 50 to 70c. Higher temps also let you use more fan speed without the added risk of warping so you’ll probably see better overhangs even though the temps are higher.

    Id start with adding some chamber temp sensors first so you can measure what difference you are making with the other mods.

    Using 4 mm abs panels I saw about a 15c improvement by just throwing a fleece blanket over the printer, so that might be an easy fix if you don’t print large parts frequently. Although higher temps are also great for layer adhesion on smaller parts.


  • Yeah ridga or vzhextrudort style gears definitely help greatly. You could do a mihai style test to see if the artifacts on the i3 are mostly extruder related or from the XY motors.

    Tuning drivers consistently for quality is going to require an oscilloscope, although there are some experiments with attaching an accelerator to the motor while doing a frequency sweep.

    Of course you could just change settings and see if there is a visual difference, but there are too many settings and combinations to make that realistic.








  • I personally don’t mind textured pei for small mechanical parts but the roughness and depth of the texture can vary wildly.

    But take a look at g10 fr4 sheets, they work perfectly for pla/abs/tpu and have a flat finish. A 330x330x3mm plate should only run you about $25 less if you can source it locally.

    Edit: the side cooling fan is only useful for speed benchies or doing a plate full of parts with overhangs where the fan on the toolhead doesn’t spend enough time in one place to cool effectively. The side fan might also be placed too low, impacting bed temps more than it ideally does. If you plan on using it more I would recommend doing the bed pid tune with the fan at printing speeds.
