Thanks to everyone. Just ordered the ethernet board, 5 inch display and the breakout board.

Has been some time since i have been able to work on this. have been working in Dominican Republic to relocate some of our equipment, but now back at starting on this. I took a look at the config tool page and it did not show a option for setting up a x,y,z axis type machine with a extruder . Which option should you choose, or is it considered a custom setup? Thanks

Re: Do you have know Gcode to set up hardware

Priority change at work so had to put the Duet on the bench for a few more days but still thinking a lot about the project due to how we actually looking at using it on a R&D prototype. Part of our setup will be a floor mounted extruder that is pellet fed. This extruder is a old machine we purchased about a year ago to test on lamaination projects and i installed a AC inverter in it to control the speed and feed rate of a melted polymer from a Allen Bradley PLC based on the speed that multiple sheets of fabric are being fed.
To make a long story short, this is the extruder we will be using on the 3D type x,y,z table we will be testing. There will be a hose coming from the extruder that will be mounted and the x,y,z table will move under the hose as the material is being applied.
On the Duet and all 3d printer boards i have looked at or at least to the best of my knowledge use stepper motors so the extruder output is a pulse and direction signal to a stepper contoller based on the feed rate required for the extruder.
I have ran across the following item in a link i have attached that takes a stepper step signal and converts that to a 0-10v signal. Looking at possibly connecting the extruder signals from the Duet into this board to give a 0-10v signal output that could be used to control the AC inverter that is in the floor mounted extruder.
Any reason why this would not work, or any advice?
Thanks

Thanks to everyone. I realized on the drive home after getting off work that i was wrong in my previous post.
Spoke before i fully thought. As soon as i got in the car i realized that dummy, the two connectors on the board as SupraGuy said are wired in series to a single driver and then realized as DC42 said, just remap both to be a Z, which is why i chose the Duet over others in first place. Not that great with the G code but hope to get a lot better .
Thanks to everyone, learned to read and think about it a little longer before rushing to ask.
Have a great weekend.

Thanks, will read in more detail but it appears your description, which is a great write up is explaining how to wire the output side of the stepper drive to two motors. What i was wondering is, is there a way to wire from the A4 terminal of the breakout board Step+, Step -, etc. to the input of both external stepper driver controllers? Or like on the main Duet board there are two connectors labeled Z and one has a jumper that if i understand correctly you remove to add another Z motor and both Z motors are then controlled identical through the connections of the main Duet board. Hope i can explain without being too confusing.
Thanks

Thanks, could you explain in a little more detail. The wires coming of the Step, Direction etc. from E4 on the breakout board would go to the external stepper controller #1, how would you connect to stepper controller #2

From studying the Duet3d Ethernet i have ordered i understand the board has two rows of connectors that can be used to control two Z motors and they behave identical.
My questions is what if you use the Duet Expansion Breakout Board which i will have to do after testing in the lab due to fact the machine we are retrofitting has very large Nema 34 motors and already has Automation Direct STP-DRV-6575 Drives and management says to use them. I have a little understanding when it gets to that point that you have to remap the drives etc. but how would you wire the board so that two Z axis motors would behave exactly the same. The carriage on this machine is very larger, about 60 by 60 inches and has two stepper motors on each side to control the Z movement.
Could you parallel the wiring that you would use for E4 on the Breakout board that will be wired into one of the external Stepper Drives to the second Stepper Drive?
Thanks

Actually this kind of post helps folks decide which product to use. Have not had a chance to hook anything up yet, just got the parts and leaving for a few days but have researched a lot of others and asked questions on the forum and sent emails and this one is by far the best.

Now this has been very helpful. Great post with actual wiring diagram attached and G code. Plan to take this home this weekend and print out the G code and search G code commands and get a better understanding of exactly what each line of code is doing (New to G Code), background is PLC and Automation but really getting interested in learning this.

Thanks for info
Just ordered the Ht-225d since we have a account with Newark and they sell it.
