[turret inside planet core]

found turrets in (i think, perfect) middle of planets multiple times.

 

edit: attachment contains screenshot (you can see the gravity detectors pointing right at it)

[impulse giver/motorized hinges]

i was trying to make a ship that dug to the core with an impulse giver, a not-gate, motorized hinges and lasers.

the plan being that the lasers would go back and forth mining the planet.

problem is the lasers would slowly start drifting away  from where they were pointing and start glitching.

a solution would be a rotation cap on hinges.
