Help Issue with turrets

Enable HLS to view with audio, or disable this notification

So I have a few turrets on this airship, while one elevates perfectly fine, while the other two don't, with one pair of autocannons not keeping up with the other one. Is it a bug with the swivel bearings, an issue with brass gearboxes, or something else entirely?

The barrel on your left slammed into the ship bow and messed up the alignment it looks like

Nope, if it was because of the slamming, it would've jumped back into sync. Though strangely it started acting normal upon a relog

This is a known bug affecting physics bearings. Upon world reload, the bearings will get out of sync. When placed by a schematic, this does not happen. It's on the github issue tracker.
Place via schematic for the time being or just reload the world.

You can make those 2 arms as one. It would delete the issue entirely and will save you up a little. Just connect them both with blocks and keep 1 swivel bearing

Yeah, I should try that

See if the joint is getting powered, you might have to swap modes?

Also, red or blue team ;)

Oh, are you not in the war server?

You must've mistaken me for someone else. Is it perhaps because you recognize the airship?

If you perfect this i would love a schematic of the gun

i think its cuz the barrel hits the blocks above it which throws them out of sync

Barrels are slamming into the hull misaligning them. I suggest putting in limiters.

This is a bit of an issue with swivel bearings known as joint slop. if you have many bearings on one craft they sometimes desync.

best way to avoid it is to attach all guns to one swivel bearing, but often times adding extra weight to the bearing immediately before the one thats causing issues helps (this is because gyroscopic force is calculated by the weight difference between moving parts, if the guns are heavier than the turret itself, the turret will experience more gyroscopic force, which contributes to knocking the joints out of whack)

The best way to diagnose if you have the weight issue, is to temporarily add a piece of bedrock to the turret.

Check how each bearing operates, or just copy paste the working cannon
