Gestures

Every gesture is a short G-code sequence. The Z axis carries the stylus: M3 S12 lowers it to touch the glass, M3 S0 lifts it. G4 P<seconds> dwells; G0/G1 move.

Single tap

Move to the target, drop for 50–100 ms, lift.

G-code

G0 X.. Y..      ; move to target
M3 S12          ; stylus down
G4 P0.05        ; dwell 50 ms
M3 S0           ; stylus up

Long press

Identical to a tap, but the dwell is held ~800 ms.

G-code

G0 X.. Y..
M3 S12
G4 P0.8         ; hold 800 ms
M3 S0

Swipe

Touch down at the start, move under load, lift at the end.

G-code

G0 X.. Y..      ; move to start
M3 S12          ; stylus down
G1 X.. Y.. F3000 ; drag to end at feed 3000
M3 S0           ; stylus up

Double tap

Two taps with a short gap (< 300 ms between touches).

G-code

; tap
M3 S12
G4 P0.05
M3 S0
G4 P0.1         ; gap 100 ms
; tap
M3 S12
G4 P0.05
M3 S0

Tuning touch

If taps don’t register, increase the Z depth (S value) slightly or the dwell (P). If the screen scratches or double-fires, decrease them. Values are saved by calibration.
