[15:46:50] === PHASE 0: MIC CALIBRATION ===
[15:46:53] Ambient RMS=127.3  Beep threshold set to 1273.3
[15:46:53] Sending startstop to calibrate beep level...
[15:46:58] Beep calibration: heard=False  peak_rms=1204.0  threshold=1273.3
[15:46:58] WARNING: beep not detected above threshold — mic may be too far from turntable.
[15:46:58] Adjusting threshold to 636.6

[15:47:03] === PHASE 1: SPEED RANGE (CONTINUOUS MODE) ===
[15:47:03] Setting speed to FLOOR (25x slowdown)...
[15:47:18]   [MIN SPEED] Starting continuous CW... enc_start=-32018
[15:48:43]   [MIN SPEED] 360deg in 77.1s = 1.28 min/rev
[15:48:43] Setting speed to CEILING (25x speedup)...
[15:49:01]   [MAX SPEED] Starting continuous CW... enc_start=-35777
[15:49:39]   [MAX SPEED] 360deg in 30.0s = 0.50 min/rev
[15:49:46] 
[15:49:46] === PHASE 2: BACKLASH MEASUREMENT ===
[15:49:57] Control test (CW then CW, no direction change):
[15:50:24]     CW 180deg (1st): delta=-1140 counts (-171.0deg) dur=14.0s
[15:50:44]     CW 180deg (2nd): delta=-1134 counts (-170.1deg) dur=14.0s
[15:50:45]   Control: total=-341.1deg  sum_expected=-341.1deg
[15:50:45] Backlash test (CW then CCW reversal):
[15:51:10]     CW 180deg: delta=-1138 counts (-170.7deg) dur=14.0s
[15:51:52]   Backlash result: net displacement=1615 counts = 242.25deg
[15:51:52]   (0 would mean perfect return; positive = mechanical slop)
