Is there a way for the Duet3d to detect when the extruder filament runs out or break to automatically start the pause script and wait for someone to fix the issue and resume the print?

In their white paper it says they used DC Servo motors.

Thank you, by unless there was a combo network card, I only meant that I might wait for such a board, however, I will use WiFi since it is either WiFi and Ethernet.

My heater pad will have thermistors for each zone as well, do I need the PT100 expansion board and daughter board to connect the two thermistors?

I am planning to use 24v power supply for the motors, what other voltages do I need the power supply to support for the electronics (12v or 5v)?

I’m in the US, should I order directly from you or from a US supplier of the Duet3d?

What are the main advantages of using a larger PanelDue and LCD screen over the smaller version?

Thanks,
Kyle

This is my first post and I am new to building a 3d printer, I do however have a 3d printer I have used for 3 years. For many years I troubleshooted and fix large mainframe computers and printers, so I have a fare background in electronics and mechanics. That said, after reviewing a number of boards the Duet3d seems like it would be a good fit for my project.

Originally I considered building The Beast from the kit to use as a base for my project, however, I decided to take on the challenge of designing and building one from scratch.

Where I am initially going to build a standard 3D printer with 4 filament heads, I am deviating from the normal designs. I intend to drive the filament Extruders using Motors on the back of the printer but unlike Bowden designs I will be using a Flex-Drive Shaft to drive the filament drive. The main reason for this is I am actually designing a Pellet Screw driven Extruder systems and to lighten the head I want the motor and flex-drive to be used to drive the screw of the Extruder. Also to really complicate things, I want the Extruder heads to be removable and be able to support a mix of Filament and Direct Pellet Screw Extruder at the same time.

Here are a few questions:

First I will be using the Duet3D Wifi? (unless there is a plan for a combo Wifi & Ethernet card - would love to have both) with the Duex5 Expansion card, and the PanelDue display.

I want to build the system with two Y Axis independent and two x Axis each with Independent heads. This way Y1 Axis with X1 Axis Head 1 and X1 Head 2 can align to one direction with each head homed left and right. Then the Y2 Axis with X2 Axis Head 3 and X2 Axis with Head 4 can align align to the opposite direction from the other Y axis.

Is the Duet3d capable of supporting such a setup. I know it supports multiple x carriages in the IDEX configuration and two heads for printing the same part?

Also, my 24" x 24" aluminum printer bed will have a 2 zone 110 volt heater pad, in the middle is zone 1 12" x 12" with will be controlled by a Solid State Relay, and the Zone 2 with is made up of the 6" around Zone 1 will be controlled by a second Solid State Relay, does the Duet3d support zones that can be turned on independent of each other? (2 heater circuits).

by supporting the multiple motors for the Y Axis and X Axis setup, can each motors be driven from its own driver and circuit from the Duet3d without having to run them in series or parallel? Can they be sync together if they have multiple motors?

I hope this all make since, I know this printer 33.5" x 33.5: x 42" will be a challenging to complete and have running, but I am looking forward to challenge. I will be using all Clearpath hybrid motors, a 16MM RM1605-750mm anti-backlash ball screw with Nema 23 for the main print bed with Guideway Linear Rails, and Guideway Linear rails for the Y Axis and X Axis.

Thank you, for any comments forth coming.
