MacroGoblin can be pretty overwhelming to a typical bot user, it has a TON of features that out of the box confuse a lot of people. It requires you to read to figure out how to make stuff work. I've spent a lot of time with the Space Bots and have a pretty good routine to level from spaceship -> 50 with a small break around lvl 29 when there are no space missions that give experience.
If you are a MacroGoblin user, take a look in the SWTOR Space Mission Botting forum. There are a TON of user made space bots that will pretty much walk you through what to do. I'll see if I can put together a HOWTO guide and share some more of my experiences with the individual Macro Goblin Space Bots (i've used them all).
The difficult thing with space botting is that its all recorded with some having pixel detection starts, as an example Mugaar Ice Field I used to level from 34-40 in about 2 nights time. When you start the mission it waits till the timer gets to 4:29 (looking at a green pixel on the 2 in :29) and the routine kicks off. You need to basically adjust the pixels & delays to make the bot shoot when its supposed to.
Computer speed, server load, etc. all play into this and the delay needs to be adjusted almost every time you run the bot.
I'll see if I can put a guide together over the next few days to help some people out, however if you have a MacroGoblin account, you can easily find it there.
