Pro42 Alignment Software Update Upd

Immediately post-update, engineers noticed that the PRO42’s ambient noise floor dropped by 1.7 dB—despite no changes to the analog front end. Forensic analysis revealed that the new quaternion filter inadvertently phase-cancels a specific 60Hz harmonic generated by the alignment motor’s PWM controller.

Result: PRO42 units are now effectively immune to a common interference pattern from nearby industrial equipment. This is being quietly patented.

The patch worked flawlessly in this regard. Hysteresis is gone.

⚠️ Troubleshooting tip: If the update stalls at 87%, it is likely a firewall blocking port 4433. Temporarily disable deep-packet inspection on your shop’s router.
