I understand that the parallel stepper motor controller I have will not work in Windows 10 and I need to use a Remote Motion Controller,  according to a moderator, the parallel port cannot be used in 64bit W8/10
I have a full kit of hardware and electronics as per the Book "Build your own CNC Machine" (Hood/Kelly) . My son and I are soon commencing the construction of the device.
Can someone point us in the right direction regarding these Remote Motion Controllers?  I have found some on EBay starting at around $100, Can someone point us in the right direction so we get the right unit.  

We are using a Dell Optiplex 780 SFF desktop with 4G of RAM running W10 64bit.  As raw newbies at CNC any help would be appreciated.  My son is a whizz at computers and should have no problems with the software & G-Code management.  I have over 60 years electronics experience so the hardware assemble will be no problems.  Just a case of obtaining the correct boards.  Our parts include the stepper motors and tool motor with speed controller, as specified in the book. Together with bearings and other hardware.

Thanks Dave & Mark

I'd stay away from the chinese motion controllers on Ebay.

A good, low cost motion controller is the UC100 from CNC Drive.
Another very popular option is the Ethernet Smoothstepper.

UC100 is by far the easiest to get setup and running.  it is a great piece of hardware.  I have installed hundreds of them.  The only problem I have ever run into with one was a bad cable.

I have no idea which is the best or the easiest to set-up external motion controller but I use a Warp9, Ethernet, SmoothStepper. They have excellent back-up and after sales (bit slow on releasing plugin software updates  ) supported by their own forum http://warp9td.com/

Tweakie.

Hi DaveS Welcome!
Like you I also started from ground zero. I'm by far no expert on anything.
After 5 years of building and running our mill I would have to say I would
not be where I'm at today if it was not for this forum. I also give this forum
five stars *****.
I started out with a dell computer, parallel port, BOB, and Gecko drives, and
Vectric VcarvePro.
Today I still have the same setup except with a Smooth Stepper.
VcarvePro is a great piece of software.

I have ended up with 2 feeds running on this.  Not used to Forums:)  But as I mention on my other post.  I have found this forum to be the best I have visited, even stunned the Moderator by giving the forum 5 Stars    No seriously.  I have received great support and information so far and I am somewhat overwhelmed trying out the various suggestions.

Its going to take few days to evaluate all the suggestions.  So far I am strongly leaning towards 2DCut.  My son Mark will be coming up to town on Thursday and I will unleash the plephora of software on him and see what he likes.  (He's the software man.  As I have said I am the nuts and bolts department

Cheers  Dave & Mark
