Replacing Duet with Arduino Due and specific Shields or Grbl

Greetings,

So I am trying to build an Ormerod 2 without buying the kit. I am from Tunisia and getting everything shipped is a bit expensive + I want the experience of making everything on my own (Well , except for the printed parts : a friend suggested to mail them and it doesn't look problematic).

The actual problem here is the controller. I was thinking whether it would be possible to replace the duet with an Arduino Due and use available shields to control the stepper motors/thermistor/ethernet etc ... and was wondering whether I'll be able to get the same web interface and firmware to run on it (as getting the shields and the arduino is far easier than ordering a board here and takes much less time).
I was also wondering if I could get the cheaper arduino Uno and get the Ormerod to work with a similar precision using Grbl( I know I'll probably have to sacrifice all the GUIs but I can manage some command line if it means a cheaper prototype with the same quality).

Thanks
(Oh and this is also my first contact with the world of 3D printing)

Hi nebras,

The current RepRapFirmware will run on an Arduino Due, however be aware the the Duet uses several pins that are NOT available on the Due. I guess it would be possible to simply change the missing pins in an individual firmware branch, but be aware you'll have to maintain your own fork in this case. I don't know Grbl, so I cannot say what you need to consider if you decide to go with it - maybe ask again in the Developers forum, I figure a few people will be able to help you there.

I for one am happy with the Duet, having a 3D printer with a LAN port often simplifies things, especially if the web interface is good

The Arduino Due has no Ethernet port, so you would not get a web interface.

Thanks zombiepantslol ,

My idea is that if the firmware is compatible with the Due then I can simply get an Ethernet Shield (This [www.arduino.cc]) , 3 stepper motor control shields , and simply toy a bit with the firmware to get it working with all the Duet's potential (for one printer that is , I know it can be extended and all). Do you believe it could be possible ?

I just found a new device.
Can this replace the Duet board?

No, the processor on that board is way underpowered.

Okay it was only an idea. Because it has Ethernet, USB and an microSD-Slot.
