Network Connection

This a complete troubleshooting procedure used to determine the issue behind any connection issues to Duet Web Control (DWC).

DHCP (Default Setting)

Verify You Have DHCP

Open the "machine_access.g" file (located under sys folder).

Locate the code: M552

Two things to check:

  1. Look for this exact, matching code, with a single line. Dismiss anything after S1.

M552 P0.0.0.0 S1

2. Make sure the semicolon (;) character is not present before the M552, within the same line.

; M552 P0.0.0.0 S1 ; DHCP - IS - enabled.
M552 P0.0.0.0 S1 ; DHCP - IS NOT - enabled.

If any of these two items are not correct, you may be using a Static IP.

Verify IP Substitute Name

Open the "machine_access.g" file (located under sys folder).

Locate the code: M550.

Your IP substitute name is:

M550 P[here]

Example:

M550 PFrankie

Enter the name into your web browser:

Continue if the DWC could not connect:

Verify IP Address

OR

Here is simplified version:

Download YAT.

Connect the Duet Maestro (your board) to your computer using the USB connection.

Open YAT.

Pick the correct COM# port. Click "Okay"

If you don't have the "Duet 2 Maestro 3D printer .. " label show up, it's not too important.

If you want have to "Duet 2 Maestro 3D Printer ..." show up, follow the Installing the Duet Driver guide.

Enter code (into the bar labeled "Send Text"):

M552

Possible Response #1:

Network is enabled, configured IP address: 0.0.0.0, actual IP address: 192.168.1.##

You have a valid IP address. Enter the IP address (e.g. 192.168.1.54) into your web browser.

Possible Response #2:

Network is disabled, configured IP address: 0.0.0.0, actual IP address: 192.168.1.##

Your network settings were disabled (off).

Enter:

M552 S1

Re-evaluate response.

Possible Response #3:

Network is enabled, configured IP address: 0.0.0.0, actual IP address: 0.0.0.0

A 0.0.0.0 IP address means: the Duet (board) did not connect to the internet.

Check your internet connection.

If you're sure the Duet (board) has internet connection, move on to the next step.

Check SD Card

Make sure the SD Card is installed into your Duet

{pic}

Do Not install or uninstall the SD Card when the printer is on. You May Burn the SD Card by doing this.

Return To YAT.

Enter:

M21

Possible Response #1 & #2:

[NOTHING]. Literally nothing.

OR

No SD car present.

Your SD Card is not being read.

Make sure the SD Card still works, by verifying you can still see the SD Card's content through your computer.

If you cannot, you need a new SD Card. Refer to Updating SD Card for repopulating your new card.

If you can, we recommend reformatting the SD Card (follow official Duet3D microSD guidelines).

Possible Response #3 & #4:

SD Card mounted in slot 0, capacity ###.##Mb

OR

SD Card has open file(s).

Your SD Card is being read. Move on to the next step.

Check SD Card Content

Connect and open the SD Card to your computer.

Make sure your root folder is exactly as shown below:

If not, re-organize until exact.

OR

Delete-all and Copy-Paste from official Promega SD Card Content.

Re-install the SD Card into the Duet board. Enter valid IP address or substitute name.

Static IP
