Hey Bob
If your ArcDroid was purchased between Sept and Nov 2022 and it is struggling to lift the head then it is almost certainly afflicted.
The issue is actually a nut that was too loose! and insufficient lube causing vastly premature wear. Seems to affect about 5% of the ArcDroids produced during this time.
Please send us an email with your details and we’ll send you a repair kit ASAP
Cheers
