Duet 3 - Diagnosis LED - Will not stop blinking
-
From:
https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Error_codesFrom the above weblink, ''Note: continuous rapid flashing indicated that the CAN connection is lost."
Status says "Idle"
I have setup a config file.
Why does Diagnosis LED keep blinking?
-
1hz slow and steady? thats normal.
-
Yes, slow and steady.
I still can't get a stepper motor to move.
I have re-install DuetPi and ran the following commands on the Pi:
sudo apt-get update
sudo apt-get upgradeMy next step is to run the command below to activate the control port :
sudo raspi-configCorrect?

How are you trying to command the movement? Do you get any error messages?
Bear in mind that the printer must be in a homed state before movement is allowed unless you specifically send a command to unlock movement.
How are you connected and how are the motors configured in config.g?

So not a problem then. (admittedly a red flashing led may not be ideal OK indicator, but it is what it is)
I'm guessing your motors won't move because the firmware is preventing you to move anything before the machine is homed.
So test your limit switches.
Fix the homeall.g fileor override the limit with https://duet3d.dozuki.com/Wiki/Gcode#Section_M564_Limit_axes

so I ran:
ls /dev/spidev*which returned:
/dev/spidev0.0 /dev/spidev0.1This is my four 3d printer. But, my first scratch built 3d printer.
On the Duet3 main screen at Machine Movement
States:
The following axes are not homed X, Y, ZMy main objective at this point is to confirm my motors and wire harness are working.
The machine I built is Core XY. I do not know how to setup the limit switches yet for the X axis and Y axis.

Thank you for confirming the problem is what we both just told you.
-
See if this gives you some hints on first commissioning. https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+3:+Commissioning/39

Do you have a user guide for DuetPi on how to use the web interface?
Where do I run the command:
M564 S0 H0 -
Getting connected to the web interface is largely the same as a Duet 2 Ethernet.

Once you have the IP address of the Duet you can connect to the Duet Web Control (sounds like you are already connected to that?)
You can send commands via the Gcode Console tab of the DWC (see left side bar)

States:
The following axes are not homed X, Y, Zat the top of that page, or alternatively on the console page from the menu on the left (possibly docked on a small screen)
-
for reference:
-
Completely illegible picture of the screen, but from the size of the buttons it looks to be quite low resolution so no idea how DWC renders.
If you can't find the input at the top or the docked menu then maybe you'll be better off accessing DWC through a browser on a device with a higher resolution at http://duet3.local/ or substitue the IP address of your RaspberryPi if your client doesn't support mDNS

This will definitely make initial setup easier. Once operational that screen will likely be ok for print control.
-
I can read the screen. I entered m564 s0 h0 into the console and got the stepper motor to move.
My next step is to figure out the config file to map the correct drive to the correct motor.
-
maybe you could change the title of the topic to avoid perpetuate the misconception that the flashing LED is a problem?

Were you able to use the web config tool to get a starting point? If you post it here we can make suggestions.
-
what topic to you recommend?
Basic setup or unlock stepper motors?
-
I think the title is probably fine. If others have the same concern about the blinking LED maybe they will find this thread and see that it is actually normal.
If you wish to continue the commissioning discussion perhaps best to create a new thread with a more accurate title and include as many details about your printer and current configuration as possible.
-
Just finished the config file. I received a lot errors. Need to go through each error by myself.
Next, I will setup the web interface to my computer and go through the errors.
Thank you for the help.
