Re: Getting Started with Servo CNC

No problem and thank you Jeff. This has been so much fun building
and it is working so good.
I should have it done very soon. But the salmon fishing has been
great and I do enjoy that also. And our oldest son is getting
married in one week so It will be a few weeks more but I should be
done by then. When its done I will let you know and invite you over
to see it.
Yourself and Mariss at Geckodrives have been so helpful I cant
thank you both enough.
