For leveling:
(Leveling needs only 1 set of mats. Hence this is the cheapest way to level.)
Buy one set of mats. Manually craft to the final step of the synth.
Press the record button on WPE.
Do the final step.
Press stop on WPE.

Do not move your char.

Right click the 96 packet jobbie, click send.
Set up Continuously, and 1700-2800 depending on latency.

Click the play button.

It will keep firing the message that finished the synth, this means that you will keep getting the EXP as if you did the synth over and over.
