The beginning of what I wrote was following your guide, but then you take the long way. So I rewrote it for you:
Move ladder M: right, up, up
Move ladder T: right, right, right, down, left
Move ladder B: left, up, right, right, right, right, down. Should be next to ladder T.
Move ladder M: down, left, left. Should be in the middle row.
Move ladder B: up, left. Should be beside ladder M
Move ladder T: right, up, up. IN POSITION
Move ladder B: right, down. IN POSITION
Move ladder M: right, right. IN POSITION
I don't know why there were so many more moves involved. I've included a video on youtube and I can email you a picture I made of the ladders with labels for visual assistance. https://youtu.be/VoiFD3GUZcY
No credit needed man I just wanna help.
