I crushed my Duet Board!

Hello,

unfortunately i destroyed my duet board through a short circuit now i want to buy a new one. My omerod is now about 1 1/2 year old. I think there have been some changes of the board since i bought my printer. Also when i look at the wiring instructions of the omerod 2 i see significant changes of the wiring diagram.

What must/should I consider when i buy a new Duet Board ? Is the wiring diagramm of my omerod 1 and the "old" software still compatible with the Duet Boards ?

thx for your help

You have a choice between the Duet 0.6 from Replikeo, or the Duet 0.8.5 or Duet WiFi from Think3DPrint3D.

The 0.6 is the cheapest and is the same version as your Duet, however some users have had problems with boards from Replikeo. Also I don't know whether Replikeo still fits the ribbon cable connector for the bed heater, so you might have to add it yourself or use flexible 2 core cable to connect the bed heater instead.

The 0.8.5 has a number of improvements including dual extrusion support and a second fan output, which can be used to control the hot end fan thermostatically. You would need to use 2 core cable for the bed instead of ribbon cable, and connect the Z probe and hot end fans to the dedicated connectors for them. Also the hot end heater connections are screw terminals.

The Duet WiFi has the same connectors as the 0.8.5. As well as WiFi instead of wired Ethernet, it has TMC2660 drivers, which make the printer quieter.

You can get help with any rewiring you need to do either here or on the Duet forum.

I prefer to spend more money and have less problems also the changes of the Duet 0.8.5 sounds reasonable. so i will order a Duet 0.8.5.

thanks for your help and for the detailed response!

In my last communication with Replikeo recently they said they are considering whether to continue Duet production.

Hello,
i got my DUET 0.85 Board yesterday. I want to use the wiring diagramm of the think3dprint3d site. Most of the connections of the wiring diagramm are clear for me!



1. 5V Connections
Do i have to supply the board with 5V ? I guess when i dont connect the board to 5V, the USB Cable have to be connected to the board !?

2. Hotend Wiring
At the Omerod 1 Wiring diagramm the Hotend needed 4 Wires a supply. I think 4 wires are no more needed ?! Do i have to pay attention to polarity of the thermistor ?

3. DC's Mini height sensor board
Is my assumption right that i have to put the MHS Board on the probe connector ?

4. Heatedbed
I still use the heatedbad of the omerod1. The "old" Heatedbad uses Ribon Cables for the power supply. Should i remove the IDC connectors and solder a new plug for normal single core cables ? or is there maybe a other work around ?



Do i have to pay attention to something special when i wiring the new board ?

thx for your help

Hi Thomas,

Some of your questions are answered at [duet3d.com].

You can put a jumper across the 5V_EN pins to generate 5V power on board.

The thermistor polarity doesn't matter unless you are using my Ormerod IR sensor board.

You will need to rep!ace the ribbon cable by 2 core flexible cable.

You may wish to connect the hot end fan to the FAN1 connector and control it thermostatically.

Either reverse your stepper motor connectors where they plug into the Duet (power off before you do this), or use M569 commands in config.g. See the M569 commands in [duet3d.com].
