Test print start: guard peaks 1-8 in every phase except the brush scrub (peak 47, 4 reads above 30 in a row), 0 I2C errors; a light finger push gives 41. Stop mode for all phases, the brush stays log-only. The contact homing in HOME restarted 6 times (sample spread too large) while the nozzle was still heating to 150C; PRINT_WARMUP now waits for a steady contact temperature first, as PRINT_START does.
