Pressure advance scorecard
Choose your file in the firmware menu (or type the values of a custom range), score each band on screen or on paper, and let the rule pick the value. How to judge each probe: pressure advance guide.
Write down too: firmware, nozzle, filament brand, type, colour, temperature, test speed (98 mm/s) and acceleration, date. A value without them is useless next month.
The columns follow the hex pinwheel model v1.3.0 (coarse and fine files are both in the firmware menu). 90° tips, 45° tip and Straights decide; Seam and 120° only confirm; Inside is shown but not counted (a concave corner is rounded by the bead width at any PA). Printed on A4: the rules on page 1, the whole grid on page 2.
How the best band is chosen
- Hold the tower with the engraved band numbers facing you. Score each band on its own, in its middle, away from the divider groove: ✓ pass, L fails because PA is too low (bulge, blob, filled corner), H fails because PA is too high (rounded, gap, slit), – cannot judge.
- Go up from band 1. A band qualifies when both 90° tips are ✓ and no counted probe is H. The Inside column is not counted: a concave corner is rounded by the bead width in every band, so do not judge PA there.
- Your value is the lowest band that qualifies. The 45° tip may still be L there: that is normal.
- Tie: if the band just above also qualifies and has at least as many ✓, take that higher band (when in doubt, lean higher).
- If the result is band 1 or the top band, the value may lie outside the range: print the other file of your firmware (coarse after fine, fine after coarse).
- Sanity check: L marks belong at the bottom (low PA) and H marks at the top. Marks scattered at random, or L and H on the same probe of one band, point to something else: see Troubleshooting.
