OK, so here it goes:

FIRST OF ALL: GET AWAY FROM ALL CRAFTING STATIONS OR DROIDS --- THESE WILL
MESS UP MACRO -- GO SOMEWHERE QUIET

1. Get an open toolbar
2. Get a minimum of 5 crafting tools
a. Get specific tools for specific professions
3. Place the tools in Slot00 - Slot04 (remember, Slot00 is the leftmost slot
on the top row)
4. Create a new macro (Ctrl-A | New Macro)
a. Give it a good name, like CraftMacro
b. Pick an icon
c. OK, here is the macro text with comments...i will provide a
non-commented version at the end
(all comments will be placed between arrows <>)

/ui action toolbarSlot00<clicks the first crafting tool>
/selectdraftScematic ##

<Ok, this is actually the hardest part of the macro and we need to talk
about it a little
In your datapad you get a list of all available things you can craft.
These items are indexed starting at 00 and working right then down
Example: the top leftmost item is 00, the one to its right is 01 and so on.
I expand my datapad so that there are 10 items in each row (makes counting
easier)
Anyway, you have to know the index of the schematic you want to craft (e.g.,
01)

This is where it gets hard
DIFFERENT TOOLS HAVE DIFFERENT INDICES
A Generic Crafting Tool can't make everything a Weapons Tool can...thus, the
indices are different
Basically, you will have to experiment to get the right draft schematic
number...you can get in the ballpark by counting but that is about it...you
may be a little off...it isn't that bad - but you have to get it right!>

/pause 5 <this is the time you have to fill the resource slots...adjust as
necessary>
/nextcraftingstage
/nextcraftingstage
/createPrototype practice noitem
/createPrototype practice noitem
/pause 2 <this is the delay between loading crafting tools...adjust as
necessary>
/ui action toolbarSlot01
/selectdraftScematic ##
/pause 5
/nextcraftingstage
/nextcraftingstage
/createPrototype practice noitem
/createPrototype practice noitem
<REPEAT THE ABOVE CODE FOR THE NUMBER OF SLOTS YOU ARE USING --- THE ONLY
THING THAT WILL CHANGE IS THE SLOT NUMBER>
/macro CraftGrinding<this loops the macro by calling it again. You don't need to put it in the toolbar>

5. STAY AWAY FROM CRAFTING STATIONS AND DROIDS!!!!
6. GO SOMEWHERE WHERE LAG IS MINIMAL (not in front of Coronet Starport)
7. When you want to invoke the macro, simply type in   /macro CraftGrinding
8. When you want to end the macro, type in     /dump        and it will stop.

Ok, here is the full blown code

Macro Name: CraftGrinding
Icon: <doesn't matter - whatever you like>
Draft Schematic: 45 <ribbed shirt that I want to grind on for Tailor --- the
45 number depends on YOU and how many things you are able to make...i just made it up>
Crafting Tool: Clothing and Armor
Number of Tools: 5
