Got my paneldue... It says "connecting" and controls nothing...
-
Another question: The M575 command....
I'm using this: M575 P1 B57600 S1
What is the proper port (p value) for the 4 pin paneldue interface?
The instructions say Paneldue USB is P0, but does not list P values for the 10 Pin connection, or the 4 Pin connection. I am simply assuming it's P1? I've tried every P value from 1 to 9.

M575 P1 is correct for both connections. Send M575 P1 with no other parameters to verify the baud rate being used on the Duet.
Assuming that confirms the baud rate is 57600, it sounds like there may be a soldering problem with the URXD0 pin on the SAM processor (pin 75), or another problem with that pin. Unless you can see that the pin is badly soldered and you are confident of your ability to re-solder it, I suggest you ask Filastruder to exchange the Duet.

@steve-lynch Per the firmware (and the documentation), there are only two options for P: 0 and 1.
https://duet3d.dozuki.com/Wiki/Gcode#Section_M575_Set_serial_comms_parameters
https://github.com/dc42/RepRapFirmware/blob/6b835cb3c8e9aa10113ae750151d9f9065116cd4/src/GCodes/GCodes2.cpp#L3291The documentation does not say "Paneldue USB is P0", it says the main serial interface, typically a USB port [of the Duet] is P0. The correct setting for use with a PanelDue is P1.
Also per the firmware, if a M575 P1 is sent, the reply will be the baud rate that the Duet is set to communicate with the PanelDue at.
The 230400 baud rate that you saw during the firmware update is with regard to the baud rate that the firmware update is occurring onboard the Duet. The fact that this is happening is an indication that the Duet is able to send data to the PanelDue, and the PanelDue is able to receive it. That is also an indication that the baud rate is correct.
-
@elmoret thanks for the explanation. It’s very obviously receiving, but not transmitting. (Or not receiving on the duet side) I have contacted filastruder again, and hopefully we can swap it out today. I have no problem hitting the pins with a soldering iron if it won’t wreck my warranty return eligibility. Just advise on that.. I’m not going to use a 1/4” chisel bit on the board... lol. I have a nice digital hakko station, and a TS-100. I can finesse it if giving it a shot will make everyone’s lives easier.
-
@steve-lynch, one quick check worth doing: on the underside of the Duet, check that the URXD pin of the PanelDue connector isn't solder-bridged to another pin.

I received Steve's returns today, thought I'd post here in case anyone stumbles across this thread.
First returned PanelDue 7i: Tested OK, no issues, connected to a Duet we had on hand without issue.
Second return was with a brand new PanelDue7i that was sent to Steve, as well as his original Duet. I connected a USB cable to the Duet, and a 4 pin cable we had on hand from the Duet to the PanelDue7i. The PanelDue and Duet powered up and the PanelDue connected almost immediately, displaying "Standby" within about 2 seconds.
Have confirmed bidirectional communication by issuing M122 from the PanelDue7i, and the response was as expected.
I also tested powering the Duet from VIN, no problems there either, bidirectional comms confirmed. I did note that the bed heater fuse was missing/removed, unsure why.
Not sure what the problem could be, unless its the cable?
-
@elmoret I don’t understand.. I bought the cable from you, and even bought 2 more of each. (The 10 pin and 4 pin) I cannot believe I’d have 5 bad cables. The fuse is removed, because I use a 120v heat bed with an SSR, and I have a resettable 10 amp breaker I plug into the fuse holder.
If you have have it connecting as I sent it to you, please send me the cables you used. I’ll pay for it.
When the second panel due didn’t connect, I suspected that the first one was probably ok(minus the broken pins)
It just doesn’t make sense, but, if it works, that’s all I can ask for. Thanks for posting the info in here.
I appreciate it.
-
I'm puzzled as well. After @dc42 weighs in re: possible causes, happy to send the exact working setup (cable and all) back to you!
-
@elmoret, did Steve's Duet include the SD card when you received it, or did you use your own SD card? I'm wondering whether there could be some obscure config.g issue that I haven't thought of.
-
I never touched the SD card, but all of my configs are on the board the way it was when I disconnected it. Either way, I’m thrilled that it works ok, and if filastruder wants to send me back the board with the broken header pins, I’m fine with that, as i’d Never use them. Things happen. I got a batch of 6stepper cables from 3D maker parts, all of which had no continuity on the blue wire. So who knows?? Maybe my amazon ribbon cables have something weird about them. As long as I’ve got a working set when I come home from Jamaica Saturday, I’m the happiest customer ever! Filastruder has been amazing! Best communication from a vendor in ages, and absolutely lightning fast with shipping/tracking, etc!!! You won my loyalty!!!
-
As Steve said, when I did my tests it was with the SD card that he included. I just took it out of the box, added 4 pin cable, and plugged into a USB power supply.
We'll send it back with a cable pre-attached. Steve, one other possibility I thought of is perhaps something was shorting the backside of the board at the PanelDue connector, maybe a part of the frame, a screw, or a washer? Just not sure what else would be different.

FYI I spent 2 hours trying to figure this out a brand new Panel Due with 1m cable from Filastruder for my Duet2Wifi. I kept getting the connecting issue, and was stumped. Glad I found this thread as indeed is a faulty cable; +5, Gnd and Dout were good, but Din was failing when I metered it out. It's really really strange as I don't see any reason for why the cable is bad. The crimps even look good when I take it out of the housing, yet no connectivity (must be an internal break?) I made up a custom wire, and was up and running in no time.
So for those finding this later via Google like me, check the cable!
-
I'm back with this problem, at first my panel due was working fine. I don't know when but suddendly it start to say connecting.
I try to update de firmare, install the old cable, the one it came with the Panel Due, I made a new one guiding myself for the one that came with the duet. But its imposible to get connection between the duet and the board.In the config.g and in the panel it self I have the baudrate set to 57600
Any other idea??

@Makergal3D best start a new thread

@jay_s_uk ok
