In the linked video, I have a:
-Miner with a Mining Laser (also was reproduced with a Diamond Drill)
-A 12-block range Quarry Scanner (also tested with an upgraded Quarry Scanner at 64 blocks)
-64 Mining Pipe
-A tube
-A chest for the tube

After mining 6 blocks (the initial "+" and 1 block) on one layer, the Miner will then proceed to be Stuck, highlighting its own Mining Pipe as what it appears to be stuck on.

Looks like quarry scanner issue, with scanner of different type it works fine.
