Hi,
Steve, I'm hoping you will see this over here on this forum... yes I know this is not mach4 related directly... but...
I have registered on the forum @ PMDX site but have not received my activation e-mail. I have tried a couple of times. Yes I have checked my spam folder repeatedly.
Is there some trouble on that site?
I have sent an email thru the contact email address on that site but no response yet.

I am using Mach4 with a PMDX-416 on my 7x10 lathe machine n am enjoying the set-up!!!

Hope ya can help...

As you have found out they are slow to respond to their email and forum questions.  I had the same experience.  After waiting a couple of weeks for a response I called PMDX and Steve picked up the phone.  He walked me through a few tests and together we determined that my PMDX-126 BoB was faulty.  I would call.  Worked for me.
