transfer piston bug?

[Gilius Gaming]

hello, I got a little bit into the game and I have a problem.
I read that piston can be used to transfer resources.
I made a conveyor system that goes down into a mine, in which I put a collector, it works, the collector takes my minerals and sends them to a cargo ship on the surface.
I wanted to transfer from this cargo to my vehicle, so I made a piston + piston on the vehicle, and a connecting block.
The vehicle is correctly docked to the connecting block, the piston locks the second piston correctly, but the transfer is impossible, I don't understand why, but everything is correctly in place, there is just at the level of the pistons that nothing is happening.
thank you in advance

Are all piston heads welded up?

Any sorters that may block the line?

[Buzzard]

Pistons actually have 2 parts, the base (the big part) and the head (that bit on the very end that extends out). It's a common enough oversight to not weld up the piston HEAD, which makes for a break in the conveyor line, preventing item flow.

Yes all heads are well set, I even tried to do it in creative mode to be sure.
No, I didn't put in any sorters.
It's just a collector that sends a network of pipes in a cargo ship, but from the cargo ship to the ship (so with pistons, it doesn't work without any reason, I've looked at various forums before and nobody seems to have had a problem with it.

Can you show a screenshot of your setup or publish that save?

Would make identifying possible problems a lot easier.

[Gilius Gaming]

Yeah, I was already making screenshots.

here we can see, my pipes, it is connected to small conveyors, these are connected on one side to the piston and on the other side to the cargo, the cargo receives the goods, but the goods do not pass through the vehicle.
The cargo receives the goods, but the goods do not pass through the vehicle. However, in the other screens we can clearly see the piston fixation, the heads which are correctly installed and the fusion block which is functional.

Those piston heads will not connect to each other unless the merge blocks are connected directly to the piston heads.
This however has the downside that you would have to grind down one of the heads to disconnect them again.

In your situation I would use connectors for docking instead.

[Gilius Gaming]

I don't understand...?

However, the merge block merges (I placed one over the piston of the vehicle and the other over the other piston, they separate easily without having to remove them and once the vehicle approaches him and the platform melts one more, there, the piston locks I tried to launch both at the same time it stops correctly

[Gorbadon]

Your merge blocks merge your rover to the base but not the piston heads.

They are still separate grids without a connection to each other.

I just link a random screenshot from the community hub to show how docking with a connector looks like:

It's silly, since in the end the whole game counts as one block... (you can see it in the admin panel)
And I already know the connector system but it's a mineral transporter, I didn't want to make a big connector when normally a piston would be enough...
But then, let's imagine that I'm facing a piston that joins another piston on the same platform (the no vehicle they are on the same plate it's supposed to work right?).
because I wanted to test and even that doesn't work, so what's the use of the piston?

[Gorbadon]

If you realy want to connect via pistons try the following.

First grind down the merge blocks that are there, than extend the pistons.
Now build merge blocks on the piston heads (not the piston base), and merge them.
Now you should be able to move cargo, but you will have to use a grinder to seperate them again.

You may get away using an advanced rotor for docking but when you want a cargo connection your choices are limited.

what do you mean by the head of the piston? directly on it? or on top of it? because it doesn't work if I put it on, it still doesn't transfer and I can't put it on.

This will give you the easiest possible time merging two piston heads to each other though as said above you cant disconnect them once merged. Id recommend you put small connectors on the piston heads and not worry about merging at all.

Either use the oversized small grid connector that is vanilla or use

Ugh. I see the problem, and have a solution. Pistons touching tips is NOT going to work. Period.

Use connectors. They're already in game, and will provide full ability to transfer power and items.
The merge block is really not needed with a connector, so that's some space/mass saved.

I forgot small grid does not allow to build the merge block on piston heads without an additional conveyor.
In order to connect a piston head without mods you would have to do something like this:

Well all right, I don't have much choice... thanks to all of you, but it's a shame the piston doesn't allow this...
