Thanks,
I am busy with the instructions for your crane. I try to use the modifications in the blueprint file. But i must look in the file what you have changed.
I have the previous LDD version changed with the axle that RussianGuy means. And I have updated the shovels with the real 42055 shovels. (In your file I see the old shovels)
Repeating wat I say , for the tolerance issues/missing pins i have a simple solution : I add text to the pages.
To do for the instructions: motor: working section, trailer, container, lamps, and a little from arms connected to working section.
