I am sorry to see you have been left hanging for an answer on this forum. Dave has always been our support and contact on this forum however he has now left CNC Teknix. Daves duties are now being shared by the rest of us, and so Vince and myself will now be actively watching this forum and giving support for our products.
If you are still looking for a controller for your Hercus Lathe please get back to us again with the details and we will see what we can do for you.
