Records #97, #98 and #99 on the gen2 Nano Every at 6a8df02 with two 36PG-3429-19-EN gearmotors. The stall latch, speed loop, zero-speed reading, speed entry and amber LED pass. Three findings: the board held SCL low with M1 running, an 11-count position step latched an M2 stall, and M2 overshoots to 67 RPM after a short grip (#89).

Adds the 2026-11-01 bench record, on
mainat6a8df02. The board is the gen2 Nano Every, with two E-S Motor 36PG-3429-19-EN gearmotors on M1 and M2.Passed:
spd=0,0on both. Verifies fix(firmware): require DCMotorServo 1.2.1 so a stopped motor reads 0 #99 / getMeasuredSpeedRPM() keeps the last running speed while the setpoint is 0 dcmotorservo#18.M1_STALLandM2_STALLlatched about 1 s after the shaft stopped. SET_* were refused with reason 8, andfclearcleared without restarting anything. The M2 LED went amber, then green after the clear (feat(firmware): show amber on a watchdog trip or stall fault #98).Findings:
M2_STALL: PWM 16 did not turn the shaft. A 100-count step was fine (A position step just outside the deadband latches a stall #102).The record also notes counts per revolution: driven flag checks agree with the firmware's 798, while turning the shaft by hand gave 846 to 861. The datasheet gives 912 (#103).
