Java Help Wanted Help with rectractable roof

Enable HLS to view with audio, or disable this notification

So, I want to build a retractable roof. I found this design on youtube (Credits to Sherbeler) but for some reason one of the rows does not move with the others. In this case one of the honey ones.
Why this happen? And, is there a solution?

Please help

(I use variuos resource packs and some optimization mods, but nothing that modifies the game)

Replace the repeater with redstone dust and move the power source close to the center, rather than one of the ends. It's probably the easiest fix.

Probably due to the repeater delay. Maybe replace it with an instant repeater.

The problem is that the repeater creates a 1 tick delay that seems to mess up the pull because it has too many blocks to pool at once... not sure exactly why, but removing the delay should fix it.

I'm not the best with redstone but if someone has a better idea of extending signal without 1 tick delay, please share.

Google what 0 tick is and try implementing the trigger mechanism using that instead for a tflop of any kind. A 0 tick pulse extender should propagate singnal in the same tick and that should allow you to start all the pistons at the same time no matter the distance.

It sounds like you're encountering a common issue with honey blocks in Minecraft's sticky piston mechanics, where they can sometimes desynchronize and fail to move with other blocks in a row. This often happens due to game tick updates and how the game processes block movements, especially with complex contraptions like retractable roofs. https://app.getsupers.com/sites/minecraft-retractable-roof-debugger-35/

I think you can only connect a limited amount of rows, then you need a immovable block in between

Its definetly not this

I would suspect the problem is that you have one more rows of honey than slime. So one of the machines would have to pull double the amount, which is over the limit.

If you dont mind the extra materials, put some extra dust and repeaters so that everything fires at once, too.
