As topic said, Loaders doesn't work. Rotating, replanting them. Nothing helps.

Is it possible to use other loaders(like deadlock loaders/stacker boxes) if you include said mods as dependencies?
(I have no idea how mods work, I just love testing them out xD)

I believe other loader mods would work, as long as they would work in the vanilla game being able to move items between assembler and belt

I haven't had any issues with loaders. The default orientation is "extract" where it pulls from assembler to belt. If you want it to orient it to "insert" into the assembler, you have to place it in "extract" orientation and then R rotate it once it's built, which reverses its direction (like splitters or underground belts)

Yeah I got it to work with Deadlock Loaders ... only problem is that you'd have to use console commands to give yourself some xP

Just tried to put it in the extract position first .. that worked ... i must've tried insert-position every othertime bcuz rotating that did nothing... xD

Cheers.

i think he just placed loader in wrong way, it has to be placed with belt side away from building and after that you change its direction

i had that problem too. placing the loaders so that the belt part points away from the assembler and then rotating the loader did the trick for me. it's still a bit annoying to every time, but once the basic needs are satisfied, you can just use inserters.

...though on second thought, i'm not sure if my inserters come from this mod or an additional one. well, it works for me.
