@dc42 we just changed the extension board and voilà, the system is running!! Thanks a lot for your help and the hint with the 3.3 V rail, problem solved!

Best regards,

@dc42 Thanks for your help and sorry for the late reply! We disconnetected everything as you recommended and measured the 5V and 3.3 V. Here, we measured the correct voltage! Consequently, we reconnected the wires one after the other. We noticed that the error occurs as soon as the Duex v0.9a extension board is connected. Here, too, we removed the wires and connected them one after the other. The voltage problem occurs when we connect the E5 Stop plug. However, as we have not found any faults in the further wiring of E5, we have looked at the extension board again. We have probably found a fault on the extension board and would now replace it.
Thank you very much for your help! I will let you know as soon as we have installed the new board.

Hi @dc42,
Thanks a lot for your reply! I just measured the voltage at the endstop inputs. The voltage present is around 2.6 V... After that I measured the voltage between the +5V and GND pins of the PanelDue connector. Here, the voltage present is 4.1 V.... As both values are approx. 20 % too low, I think that your assumption is correct. What would be the next steps and how can I solve this issue?

Hello together,

I am using an industrial printer that is based on a Duet 2 Wifi board v1.04b with in total four heaters (2x nozzles, 1x heated bed, 1x heated chamber). The machine has in addition several relais and fuses with regard to the power supply and heating. Recently, several errors appeared which I tried to solve as there is no support from the machine provider... Unfortunately, there is still an error message whose cause I cannot find...

Below is the error history:
After starting the printer, I got the error "Attempt to move motors when VIN is not in range" and the error "Heating fault on heater 1, temperature rising much more slowly than the expected 1.1 °C/sec". In addition, a fuse was blown out that is in a curcuit for the heated chamber (heater 4). Based on this I have turned off the machine to change the heating cartridge and thermocouple, just to be sure. When I wanted to start the printer again, I was not able to reach the internal network on the installed terminal (based on Raspberry Pi). So I changed the Ethernet Modul and was able to solve that issue. In a next step it appeard that all of the four thermocouples just showed a temperature of 2000 °C and when trying to move the axes the error "Attempt to move motors when VIN is not in range" still occurs. Furthermore, heater 1 shows an error after starting the printer. When measureing the V input from the power supply I get 24 V, but when checking the with M122, the V input is around 29 V. What is interesting is that when I switch off the power supply and only operate the board via the 5 V supply, the thermocouples show the correct temperature. This leads me to the conclusion that the extension board of the thermocouples is not the cause. I have also removed this board and the heating cartridges, but the error for heater 1 remains and the voltage with M122 of 29 V does not change either...
In Order to exclude a defect in the board, I have subsequently installed a configurated Duet 2 WiFi v1.05 into the existing peripherie. However, the error message “Attempt to move motors when VIN is not in range” still appears.

Unfortunately, I have no idea what to do at the moment and cannot find the cause of the problem... I would appreciate any help and ideas!

Kind reagrds,
