Re: [CAD_CAM_EDM_DRO] Re: How to convert a Grizzly 1006 Mill to CNC - usb and other hardware(s)

Hi Hannu
Yes i agree with you, I dont have the time to testing new hardware either.
I will go with mach3 so..
But it was not so much the usb-card that i was happy about it was the dealer
here in sweden that i found from a link in david´s post.
So I going to give him a call and see what kind of things he got.
best regards
Per
