How to wire the Duet3D 3D Printer Controller & Expansion Board

[@Apollominer1886]

What gage wiring did you use?

[@CNCModellerUK]

TBH I can't remember, however I just looked up the current rating for the wire based on stepper current draw and got something appropriate. In terms of the signalling any wire should suffice as it's all low current.

[@Apollominer1886]

Anyway you could send me a picture of the final set up for the wiring? I’m working on a workbee cnc conversation using the same drivers and board just need a better understanding of the wiring layout (at least completed.

What is the advantage of using independent stepper drivers over using the onboard controllers?

[@CNCModellerUK]

Hi Miss'P', The independent drivers runs at up to 40v so you get more torque and generally better to performance in high load situations, albeit the drivers I'm using are less refined than the onboard ones. Hope that helps. All the best Barry M

@@CNCModellerUK Thanks! So - when setting up the drivers in Duet - do you need to specify / create special G-code depending on which drivers you use, or is it purely plugging the cables into the independent stepper drivers, and then choosing the settings on the toggles on the driver itself? And do you need to 'match' the drivers and the motors?

[@CNCModellerUK]

To be honest I can't remember. It's been a while but I just followed the Duet3D documentation. The drivers should work with any bipolar motor. I just played with gradually increasing the current settings until the stepper settled at about 60 deg C. Any hotter and the magnets flux will start to degrade. Hope that helps!

How to configure external stepper drivers on RepRap firmware configuration for Duet 2 wifi?

[@CNCModellerUK]

Hi Shubham, To be honest it's been a long time since I've played with my Duet. I'm currently working on upgrading to RRF V3 which has some significant differences. I'd recommend you join the Duet3D forum here: forum.duet3d.com/ The firmware documentation is also here: duet3d.dozuki.com/c/RepRapFirmware Everyone is very helpful. Hope that helps. Good luck with your build! All the best Barry M

Does the driver need power wires to the vcc and ground from the external supply or is it powered somewhere else?

[@CNCModellerUK]

Hi Grant, The drivers are powered separately to allow me to use 36v. It's the two empty connections next to the motor wires on the drivers. Hope that helps. :-)

CNC Modeller Thanks!

Where does the panel duet i7 go on the duet 3? Not one video and the documentation isn't clear on that either. Don't want short out my new board before I use it once.

[@CNCModellerUK]

I don't use the panel due, I use a 12864 display... I suggest you look here:- duet3d.dozuki.com/c/Root Or ask here:- www.duet3d.com/forum/index.php Hope you find out what you need to :-)

[@knight2255]

Big help, thanks! Were you able to reverse the enable pins with the Duet?

[@CNCModellerUK]

No worries, you can reverse the output with the configuration gcode.

Hi, may i get some advice firmware configuration for duet 2 ethernet for my cement extruder 3d printer? Thanks.

[@CNCModellerUK]

Check out the Duet3D forum. They're really helpful 😁 forum.duet3d.com/

[@ronaltlee4284]

@@CNCModellerUK thank you very much bro...

[@CNCModellerUK]

No worries. Good luck with your project. I'm no expert but the guys on there are very knowledgeable.

@@CNCModellerUK Hi, just want to ask whether duet3d support 6A DC24 or above(even AC)external controller driver? Thanks.

[@CNCModellerUK]

I think V2 boards are 12 to 24v and 2.4 A. V3 are 12 to 36v and up to 6A. I'm using a V2, V3 are very different. Check out the specification here... www.duet3d.com/index.php?route=common/home#products
