I will need to store my Lead1515 machine vertically. Considering it's weight (around 80/100kg) to move it from horizontal to vertical position would you have a recommendations ? Have you seem anybody making something like that ?
I have seen several youtube videos about this. I woudl recommend NOT doing it by muscle power alone, but use gas struts or pulleys etc to make the work easy and the chance of dropping it on the floor minimal. something like this
As David notes, there are a number of YouTube videos on the subject, many of which are simpler. No matter which you go with though, always park the system where the gantry will already be at its lowest point when the system rotates to vertical. Gravity can overcome the resistance in the screws causing the motors to spin sending current back into the drivers which can cause damage to the BlackBox.
