Thanks a lot for the answers so far, that was quite helpful and insightful. Can someone explain the backlash issues associated with "Traxxas" bearings? I'm considering using more precise plastic bearings, but I'm not sure of the design constraints yet.
For my current printer (pretty standard cartesian XZ;Y, geared extruder) I'm using 3mm filament. I see that usually, delta printers use 1.75mm filament. From my experience, 3mm filament can be pretty stiff, but is this such a huge problem with delta geometries that it will absolutely necessitate 1.75mm filament? I'd rather like to avoid buying two different filaments for each printer. Also, my hotend design works quite well with 3mm filament.
ABS does not seem to be the most popular material, but I like it for its mechanical properties, thus I'd like to use mostly ABS and maybe some PA. Does this require further design considerations (apart from using a heated print surface) specific to delta printers that I might have missed so far?
