Alright, thanks!

For wiring the mosfet it would be:

PSU to Mosfet
Heated bed to Mosfet
Mosfet to Bed terminals on Duet2Wifi

So how much AMP, thru the bed terminals, would the Duet2Wifi have with a mosfet?

The MOSFET sounds like an great idea. I have an MKS Mosfet laying around.

So i guess this will move the load to the PSU rather than the Duet2Wifi.

How many AMPs will the Due2Wifi have while connected to a mosfet with the 12V 220W bed?

I've got an Duet2Wifi i'd like to upgrade my old CR-10 mini with. The CR-10 has a bit unusual heated bed (305*235) and is 12V at 220W = 18,3 A.

Since this bed is uncommon size it's hard to find any 24V alternatives. I also prefer not to have an AC bed on this bedslinger.

On https://duet3d.dozuki.com/Wiki/Choosing_a_bed_heater it clearly states: "Direct from the Duet using 12V power. The Duet 2 (Wifi and Ethernet) is rated for up to 18A bed heater current, so this is suitable up to 12 * 18 = 216W power."

Could it handle the 18.3A on my CR-10 mini? If so i'd also need to replace the 15A Miniblade to a 20A, right?

Anything else?

Thanks for the reply!

Ah okay. It's no biggie, just a little bit annoying

Thanks!

Hey,

I have a LED-strip connected to one of the FAN-pins on my Duex5 and on boot it blinks the LED's due to fan blip.

I've tried using the B0 command;

M106 P3 B0 S1 H-1

But it doesn't seem to work. I'm using v 3.1 of the firmware.

Is there a fix for this?

@sebkritikel Big thanks!

@dc42 Awesome!

Happy new year

Puh, that's nice to hear. I thought i've got an issue.

It would be great if anybody with a duet2wifi and a duex running the latest firmware and DWC could confirm this.

Oh yeah, i forgot to mention that the board works just fine. I've got two fans, one motor and a bltouch connected to it.

Hey!

I've just noticed that my Duex5 is no longer showing up under Settings -> Machine-Specifics and "Electronics".

It's lists:

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)
Duet WiFi Server Version: 1.23

And if i run "Diagnostic" it recognises the duex;

M122
=== Diagnostics ===
RepRapFirmware for Duet 2 WiFi/Ethernet version 3.1.1 running on Duet WiFi 1.02 or later + DueX5

Can anybody with a Duet2Wifi + Duex and Duet Web Control 3.1.1 check their?

Thanks for the replys!

I'd really like it to be completly wireless.

Does the Macro-functionality support API-calls or anything like that? Or is it just g-code?

Hey!

I'd like to be able to execute a python script on an Rpi. The Rpi is not connected to the duet board.

Any ideas?

So this is normal behavior? Anything i can do to keep it stable at 24?

Thanks for the replys!

Here's a quick video on how it behaves while printing: https://imgur.com/a/Kao8khP

No issues, prints fine! Just wondered what’s causing it.

Hey guys,

I have a question regarding the VIN-sensor in DWC. While printing the other day i noticed that my VIN-sensor is jumping between 23.8-24.2 on full load. While on idle it sits stable at 24.2.

Is this something i should be worried about? I've double checked the wiring and even replaced the cables - still the same problem.

I'm running a printer with Duet2Wifi and Duex5. For powering i'm using a MeanWell RSP 500 (24v). I have a correct wiring with ferrules (shared neg for duet and duex) on 2,5 MM² cable.

On full load the machine is powering a heater, 6 stepper motors, a ender 3 heated bed (220w), paneldue 5 and some fans.

Yes, i've got one the heaters available.

Any recommendations on what can of relay/ssr that would be suitable? Any wiring examples?

Hey!

I have a duet 2 wifi and i'm currently using all of the fan-pins. For my BLV MGN Cube i'd like to be able to control four more fans (scrubbers) and i'm thinking a relay/ssr.

The fans are today connected directly thru the PSU.

Is there any documentation on how to add a relay for controlling more fans thru the duet web control?

Thanks!

@bearer is a hero and is helping me with the repair. Big thanks!
