Re: [CAD_CAM_EDM_DRO] interpolation and algorithms of multiple axes was Re: Pulse Gen

Could you also provide artwork for a through hole version PCB ?. If you do
then I would volunteer to have some boards made and low cost kits made
available to those that wanted one but can't handle surface mount or want to
search for parts.
