Searching for a " filedot model fix " yields a flood of forum threads, contradictory advice, and trial-and-error guesswork. Some blame the slicer, others point to stepper motor drivers, and a few suggest it’s a ghost in the G-code. filedot model fix
Dots are evenly spaced and match the motor’s full-step intervals. 2. Belts, Pulleys, and Mechanical Slack A loose belt or a pulley with a flat spot (from a set screw) can cause a momentary "catch" every rotation. As the belt slips or binds, the nozzle dwells for a fraction of a second, extruding a tiny blob—a dot. [tmc2209 stepper_x] run_current: 0
The s that looks like an f is called a “long s.” There’s no logical explanation for it, but it was a quirk of manuscript and print for centuries. There long s isn’t crossed, so it is slightly different from an f (technically). But obviously it doesn’t look like a capital S either. One of the conventions was to use a small s at the end of a word, as you note. Eventually people just stopped doing it in the nineteenth century, probably realizing that it looks stupid.
