My Minecraft Flying machine doesn't work

I have been making a Shulkercraft Bamboo farm in MCPE but it doesn't work. I thought it was because I had the wrong version, but my friend told me that it shouldn't matter.

The machine I built goes 1 block forward and then 1 block backwards.

Here is the link for Shulkercraft Bamboo Farm


This farm design only works on Java edition. MCPE is Bedrock edition so this design doesn't work, as redstone works differently for Bedrock.


Here is a flying machine that works in bedrock edition. Just add the slime blocks to it and use it in your farm.enter image description here
