Duex5 Problems
-
Have you wired the ground connections to the Due and DueX as described here https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring ?
-
Yes, I followed that wiring diagram. When the Duex5 is recognized the Z motors have some resistance to turn by hand like they should because the drives are enabled. When the board is not recognized, the motors turn freely like the power is off.
-
can you post the diagnostic output when all axis have moved a bit.
-
I don't know how to answer without sounding sarcastic, because I am truly looking for help, but I don't have all axis movement. I have only had all axis movement 3 times in the last week, but if I do get all axis movement I will for sure grab a diagnostic output.
-
can you post a picture of your wiring?
-
What might not be clear in the photo is the GND connection. There is individual 18awg GND from power supply to each board, but there is also a 18awg GND jumper between boards.
-
@memyr6 Suggest you remove the individual GND wires from the PSU. In bold letter here https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features it says " Do not run separate ground wires from each terminal block back to the power supply unless the power supply is very close (less than 100mm) to the Duet 2 and Duex." Looking at the picture, I'd say your additional GND wires are longer than 100mm.

@deckingman Looking at the photo, I believe he has a GND connection between Duet and Duex, no?
-
It sounds like he has both. I’m not an electronics expert, but I hear alarm bells ringing.
It also looks like you (op) have two ferrules jammed into the same screw terminal. That seems janky. Put two wires into one ferrule.
-
Yes indeed, I did not see that he has a second ground connection on the Duex5.
@memyr6, there are 2 extra wide ferrules delivered in the wiring kit, you should use those to connect the Duex5
like depicted here: https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring -
I have removed the extra ground I had and used the twin lead ferrule, no change. As a test, I also removed all wiring from the 2 boards except for the ribbon cable and powered the 5V through the USB, M115 still shows no DUEX5. I'm assuming it would show up like described in the commissioning section??

@memyr6, please ask you supplier to replace your DueX and the ribbon cable. It sounds to me that it is not always responding to interrogation from the Duet,
