Needed to print some very special 380mm tall items, so decided to modify my ender 2 to print very tall prints. it works surprisingly well, and the bad resonance only kicks in at about 390mm!

I could get threaded rod up to 700mm, and the v slot 20x40 v slot could be cut to any length.
The "hardest" part was all the new cables and connectors needed. The printer uses 2 types of connectors for stepper motors and end stops, even though I purchased a few meters of ribbon cable.
I tried upgrading the extruder motor, but sadly the old ender 2 you can't easily adjust any of the settings like esteps or pid tuning.
I thought it was like an ender 3 board, guess not. I recently got an afternoon skr V2 board and got 2 meter long cables for everything including the screen so I can put the board under the desk.
