Re: [CAD_CAM_EDM_DRO] PC-based CNC controler?

Dear Sven,

Again, thank you for your help. It may not be the whole package from one
supplier, but I have forwarded your question to Mike Johnson, at Ah ha
Design group. I have just told him about this forum. Mike has been as
helpful to me on retrofitting as Fred has been to many on this forum. I
hope he will be able to help you. He has a wonderful resource of contacts
which he freely shares.

Thanks for your help yesterday on the ways, guides ect. thread. I might add
that at times when I am cutting this aluminum, I will be cutting into areas
of aluminum where tig repair of the aluminum has been made, so it will get a
little rough at times while cutting.

If you feel inclined to respond to my follow up question on the ways, guides
thread, please consider this fact.

Thanks again.

Tom Eldredge, Trustee
