Mitsubishi DW90CHA (Nesting?)

[noisy]

Can anyone please explain to me how to use the nesting feature on our Mitsubishi DW90CHA. I've read all the documentation that we have and the only info I can find about it is on pages 253-254 of the software manual. It dosent' actually explain how to use it. I need to make 16 of these small parts and I would like to be able to nest them so I can put in my material and push the button.

thanks for any help.

The way I create macro programs on our CX-20s is as follows (I hope and presume your DW is similar). Firstly I get Esprit/w to generate the pitch program (sample below) Then create the cut path nc code for the shape I want.

Firstly the pitching program saved in L1 perhaps then save the cutting nc into L2

N10 G92 X0 Y0 (origin)
N11 G01 X10.000 Y0 F500. M91 (move to first pitch position)
N12 M20 (thread if required)
N13 G22 L2 (macro call - L2 refers to your cutting nc)
N14 G92 X10.000 Y0 (resets origin here due to shape nc program setting it's own G92)
N15 M21 (cut probably needed)
N16 G01 X20.000 Y0 F500. M91 (move to next pitch position)
N17 M20
N18 G22 L2

and so on.....

Note: Your cutting nc program needs G23 just above any M02 or M30 (usually at the end) which is return to macro

ie.

N98 G23
N99 M02

Great, thanks for the reply, I need to give you a run down of my knowledge base on this machine. My company purchased it from some sales man and he sent a tech he knew of to install it. We were sappoused to get 3 days training on it and thats what we paid for, however I was only give a 1 day crash course on the machine. He showed me how to thread the wire, change the filters, clean upper and lower head, and LOL cut a straight line. I'm not new to CNC machines or G-code for that matter. I also run 2 CNC lathes for my company and they are both Strictly G-Code programming. Between picking threw the manuals that we do have and my experience with G-Code I have been able to do anything that is required by the company. However they have thrown me a curve ball, we have a small part (4" long X 3" Wide and .700 thick. My boss knows the nesting thing can be done because of his previous job, we have talked and I explained that I have no idea how to make it work but I would do my best. I've picked threw the books and found no information as to how to make it work, i've even searched the internet but information is limited. I've heard about macros and kinda understand how they work but I have NO idea how to write one. Please bare with me as I try to figure this out and I'm sorry if I ask something that would seem common knowledge in the world of macros. I'm just trying to figure this out.

Thanks for any help.
