Wire EDM Aluminum?

[coykiesaol]

Is there some special procedure you have to use for Aluminum? I have no epacks for Al. so in the dark. I'm kind of leaning towards it being something with the machine, if you hand jog the wire in .0001" increments, it cuts, but since I don't have any experience with Al. trying to find out if there could be something I'm missing to make sure I eliminate all the simple things it could be. Thank you so much for any input!

It would be useful to know what machine you have.

Epacks are just stored call outs that set your generator up for the task at hand.

I know on my Mitsubishis that I have to lower Ip a notch or 2 and raise VG by a handful (away from steel technology) to get aluminium to cut nice.
