@dsela said in DUET 3 can't connect over ethernet anymore:

btw the M98 response is in the other thread, if you'd still like to see it.

For timely support, it is best to post all relevant info in the thread where you ask the question, even if it means repetition, rather than expecting people helping you to hunt through other threads.

@dsela said in Trouble setting up a second extruder:

question, if I have two extruders and I only want to set one, what is the correct syntax?

There's this note on the M584 Gcode dictionary entry:

Every driver that is assigned must have its current set using M906. Not setting a current will default a low current (approx 1/32 of the driver max current), however M906 will report 0 until a current is assigned. Disable the driver explicitly if you do not want any current sent to a driver that is assigned.

Though this applies mainly to internal drivers (and explains why your second extruder wasn't working), it means that external drivers have the current set to 0 in the firmware. Realistically, this doesn't matter, as that setting is not sent to the external driver anyway.

So you can set the external driver current to any value you want; it doesn't matter, as the setting isn't applied to external drivers. But you do need to set the current of the second driver, and to index that, you need to set the current of the first driver (despite it being external) to something, so it knows that the second value relates to the second driver. You can use M906 E0:1000, or set one M906 value to apply to all extruders, eg M906 E1000. While the firmware will report the current setting for each extruder drive, the current for the external driver is irrelevant.

@dsela thanks for updating us. Let us know if it starts happening again. If the Status light stops blinking again, please check whether the blue VIN and red 5V lights are still lit.

@dsela if you need the ! in the pin name then you are using a normally-open switch. The wiring to normally-open switches easily picks up interference from adjacent cables, especially stepper motor cables. So my guess is that you have bundled the endstop cable with the stepper motor cable. If this is the case, then if the endstop switch is a simple microswitch with three contacts, change the wiring to use the normally-closed contacts instead. If that's not possible then use shielded cable to connect the endstop to the Duet.

Works - Thanks!

Update - After I saw another post on the matter I've changed the M563 to D0 (instead of D40.0). Now I get no errors and the motor turns.
Thanks a lot!

Do your servos accept a step/dir signal?

@dsela said in Duet 2 Wifi runs differently after printing:

Any ideas would be appreciated..

Solving the curling would help. Can you improve your cooling, or print with a lower temp, or use a slicer feature that increases cooling and slows down on overhangs which are the most likely places to curl?

You may also be able to increase your motor current to reduce the chance of missed steps when a contact occurs. Rule of thumb for motor current is to use 60-85% of the rated max current for the motor.
