Trouble with Duet 3 6HC Raspberry pi setup
-
Hi, I have a CNC I decide to add the duet 3 6HC. For my setup, I have the duet paired with a raspberry pie 4 B. I have a large desktop monitor connected to it. For some reason it tends to stall, I can home one axis one time, or all of them at once one time, then the little circle that forms on the homing button during homing, dos not stop or go away. It seems like the process never stops, and it keeps going on an infinite loop. At first, every time I tried homeing for the 2nd time, it would home, but it would keep homeing. The axis would hit the end stop, then pull away, then come back and hit it again, and just keep repeating over and over again until I hit the emergency stop button. So I changed some of the settings in the homing files, not it just homes and stalls. Once it homes the first time, I can run one more command, but then it stops responding, and the little circle keeps on spinning, even though nothing is happening. Does anyone have any idea what could be going on?
I'm getting a low voltage warning from the raspberry pi, but no issue from the pi as far as I can tell. Could that be the problem?When I try to run g-code files, it homes and makes a few moves before stalling, it seems to run the first few lines of code, then just stalls.
Here is my config file, and my homeing files, I messed around with the homeing files to try and fix the problem, while it changed the way the homeing behaved, nothing I did ever fixed the looping problem.

How do you have the pi powered? The low voltage warning is concerning. The Pi4 should be powered with it's own supply for best results.
@amostol said in Trouble with Duet 3 6HC Raspberry pi setup:
My firmware ver is 3.01
Have you ever updated the pi and duet firmware with
sudo apt updateandsudo apt upgradesent from the pi terminal?Should probably be running 3.2.2 at least.
-
@phaedrux I'm powering the pi with the power from the Duet, I tried to connect the power via the USBC cable, but when I did that, the duet disconnected for some reason. No, I have not tried updating the pi, I'll give it a try and see if it makes any difference.
-
@phaedrux Okay I did the sudo apt update and upgrade, then restarted everything, but it made no difference.
-
Can you send m122 and post the results?

@phaedrux I fixed the low voltage issue, the power from the duet is not enough, but it did not fix the looping problem.
-
@amostol You do have a very old firmware installed on the MB6HC, please upgrade it once via bossa before you try anything else: https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_All_other_Duet_boards
-
@chrishamm Ok thanks, I'll try that. Just one question, how can you tell? This can get very confusing, the is the OS for the pi, the DWC software, the printer/cnc files (like the config), and the firmware itself, it all seems a little overwhelming.
-
@amostol Well the pi runs a linux OS, so it gets updated pretty easily with sudo apt update and sudo apt upgrade. Once your duet firmware is up to date that command will also update all of the Duet stuff as well. So when it's working, it's actually pretty simple.
-
@amostol It is part of the
M122response:RepRapFirmware for Duet 3 MB6HC version 3.01-RC9 running on Duet 3 MB6HC v1.01 or later
The latest stable version is 3.2.2 (also installed on your Pi, see the end of that response).
-
@chrishamm I tried updating via Bossa, however, I can't get my pc or pi to recognize the duet. I have erased the firmware on the duet with the erase pins. I even followed the instruction on this page https://duet3d.dozuki.com/Guide/1.)+Getting+Connected+to+your+Duet/7 to the best of my ability, but nothing seems to work. Most of the instructions on the duet website absolutely suck, they are very short and leave many questions unanswered. Such as does the duet need a sd card in the sd card slot when doing the firmware upgrade?
-
@amostol said in Trouble with Duet 3 6HC Raspberry pi setup:

Not when doing it via USB and Bossa.
Does your USB cable handle data and power?
Does the PC make a chime when you connect the device?
Do the power LEDs on the board light up?
Did you remove the erase jumper from the pins?
-
@phaedrux Yea my problem was the USb cable I was using, apparently it was power only, I tried a thicker one and it worked, from my pc at least. I also tried it from the pi, but it keeps saying it could not communicate with the duet, at least it recognized it this time. So I just used my pc and now everything works fine, no more of that looping.
Thank you very much, I really appreciate you taking the time to help me.
