    1. Do you have logging enabled (M929)? If so, is there anything of interest in the log file?

    2. Did the error occur in the same place as previously?

    3. If you upload the file back to your PC from the Duet, does it compare exactly with the original?

    1. I do not have logging enabled on the config file itself, but I did export the console log file and it only thing that states was the error attempting to extrude with no tool selected, literally an hour after i first started the print.

    2. This error occurred much earlier than last time, on layer 2 of the print rather than 8 hours into my previous print.

    3. Comparing the file (checked early in the file since error occurred at layer 2) everything looks the same.

    At least positive thing to note since once the error occurs the printer does continue to print just does not extrude so at least I do not have a spaghetti monster mess of filament

      ........................................................
      The only odd thing I can think may be an issue is I used Curas "Print on my Printer" selection rather than uploading the file to Duet and then printing from the browser.

      That is the most likley cause IMO. To prove it one way or another, try uploading the file and printing from the SD card.

        @jaurand, does your system include a PanelDue, and if so, how long is the cable and what baud rate are you using for its connection?

          @dc42 It does include a Paneldue, baudrate is set to 57600 on both the panel and in the config file using M575.

          At work at the moment so not able to be exact on cable length but its not super long, maybe 12 to 16 inches.

            Please send M575 P1 to your Duet from the console and check that the response includes "requires checksum".

                We had situations a few years ago in which commands from PanelDue were getting corrupted and causing printing to stop. That's why we set the port to require a valid checksum. Unfortunately it's only and 8-bit checksum, so errors can still get through. In case this is causing the problem, I suggest you test whether the problem goes away if you disconnect the PanelDue. If it does, then check the PanelDue cable for a bad connection. The resistance of the cable must be not more than 0.1 ohm per conductor.

                  @dc42 i was wondering to myself if it could be the paneldue. I do get some checksum errors still passed on. I'll try out next week a few more prints to see if that it and test the resistance.

                    Checksum errors suggest that there is a problem with the PanelDue to Duet link. For every 255 checksum errors reported, there is probably 1 case of data corruption that isn't detected and may cause problems.

                    What microstepping settings are you using? It's possible the use of high microstepping could increase interrupt latency and give rise to data reception errors. the 2.03 firmware series has some changes to help avoid this happening. So you could upgrade your firmware to 2.03RC4 and see whether the checksum errors reduce or go away.

                      @dc42 Tested connectors on paneldue and all are below 0.1 ohms. Currently unplugged paneldue and printing will see if any issues arise.

                      I am only running X16 microstepping with interpolation at the moment as my motors are stock with the printer and I did not have very detailed information regarding the specs.

                        @dc42 No issues with the print from tool selection with paneldue unplugged. I'll look into updating the firmware next and determine if this reduces the checksum errors

                            What sort of cable do you have between the PanelDue and the Duet? Is it running close to stepper motor wires for any appreciable distance?

                              I'm running the 4 pin wire. The cable is not close to any stepper motor wires

                                It sounds to me like a signal quality issue, but it could possibly be caused by an overloaded MCU. Are you using unusually high microstepping?

                                    I am surprised you are getting checksum errors. I don't recall seeing see any reported on my delta for over a year, and the PanelDue cable is about 1.3m long.

                                    You could try reducing the baud rate to 38400 or 19200 at both ends, to see if the checksum errors go away.

                                      @dc42 dropped the baud rate and still had check sum errors. also to note I had lost the ability to baby step with upgrading firmware to 2.03RC5 so i have gone back to 2.02 and able to baby step there

                                        @jaurand I had a lot of checksum errors too. I tried to get rid of this by mounting the duet wifi board to a different location on my printer, changing the baud rate, using different cables for the paneldue, mounting the paneldue to a different location.

                                        Searching the forum/wiki I found that twisting the wires of the endstop cables can fix it and It looks like this did the trick. No more checksum errors here.
                                        My x&y endstop cables are very close to (directly above of) one of my stepper motors: https://www.thingiverse.com/thing:3667947

                                          Hello,

                                          same problems on my printer.
                                          After Update to 2.03 and Panelue 1.23 i got a lot of checksum errors. I didnt have seen this before (2.0 beta) with 115200 Baud.

                                          Reducing raudrate to 9600 reduces the amout of errors a bit but not much.
                                          Software <= 2.0 beta have never shown such checksum errors.

                                          The problem with "attemepting to extrude with no tool selected" during print i have seen on time destroying a 13 hours print.

                                          BR,
                                          Thilo
