Been having trouble with this and not been able to find a guide elsewhere, any clue how to set up mass drivers between 2 planets and how to transport them?
To transport a mass driver, you need a cargo ship with
at least one
standard small size cargo bay (and
EDIT: preferably cargo handling systems unless you want long loading/unloading times.) Once you've built a cargo ship, then you have to go into the task group tab, find the new cargo ship (most probably in the Shipyard task group), detach it, order it to Load Mass Driver at earth, then order it to unload the mass driver at whatever other body you want the mass driver at. If your ship has a small cargo bay you'll need to give the ship load/unload orders a few more times, as they transport it in pieces rather than the entire mass driver.
Once that is done, go into the Mining tab on the Colony Overview of the body that you want to
send minerals from. Towards the top right of the Mining/Maintenance tab there should be a dropdown box that says "Mass Driver Destination." Select the body that you want to receive the minerals and the planet will automatically begin sending back whatever minerals it has mined. One mass driver sends 5000
verify tons of minerals each year, but can receive an infinite amount.
Make sure that the receiving body has at least one mass driver or the mineral packets being hurled at the receiving colony will result in mass devastation
