Hello

We have a Duet 2 Ethernet v1.06 board. One temperature channel on a PT100 Daughterboard is not working, despite of replacing the daughterboard. We found that on SPIO connector, pin CS2 is shorted with GND pin. Are we supposed to desolder it and it’s going to work? I preferred to ask first before we start to solder the board on our own.

I have tested it. On first 3, there is constant 24V on their pair of pins, not even light changes when i switch them. On the other two, voltage switches between 4-15 or 2-9 V, so when they are turned off their voltage never drops to zero.

Hello

I have encountered a problem with a Duex board. It's connected to Duet 2 Ethernet with a tape. When I connect the power supply, all of the Duex heater outputs light on, with the last two glowing weeker. When I'm switching them by gcode, first 3 don't demonstrate any change, the last two minimally change their brightness.

My firmware version is:
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05 ELECTRONICS: Duet Ethernet 1.0 or 1.01 + DueX5 FIRMWARE_DATE: 2019-12-13b1

Duex PCB version is: V0.11

The issue doesn't occur after replacing the Duex board.

In a comment, I will post the config. Here I place the board's picture.

I have re-checked the board and it seems working correctly. It must have been some mistake of the service department. Sorry for bothering, the case can be closed for now.

@Phaedrux it was purchased directly from Duet3D.

Invoice number: INV-2489

We use this firmware because we already have a system built upon it and we don't want to change it when it works well. The situation is not dependent on firmware. The exact same version goes on other printers and this FAN output operates correctly.

I have RepRapFirmware published by Duet3D, which is Duet2CombinedFirmware.bin. M115 in my terminal prints:

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05 ELECTRONICS: Duet Ethernet 1.0 or 1.01 + DueX5 FIRMWARE_DATE: 2019-12-13b1<LF>

To simplify the situation, I've made a basic config just to control these pins:
M106 P7 S0 I-1 ; Disable Fan7
M106 P8 S0 I-1 ; Disable Fan8

All of those outputs are left unconnected. I'm checking Fan7 output and Fan8 for comparison, I measure voltage on pins using a multimeter. Fan8 switches correctly, Fan7 always stays on. I'm switching them using commands:
M42 P27 S0<LF> ;Fan7
ok<LF>
M42 P27 S1<LF>
ok<LF>
M42 P28 S0<LF> ;Fan8
ok<LF>
M42 P28 S1<LF>
ok<LF>

The jumper is in position: VIN.
I'm including two pictures

Best Regards

Hi

I'm using a DueX PCB. It's a new board and I'm noticing that it doesn't switch the output FAN/LED 7. It's always shorted to GND. I've tested my printer with another, fresh Duex and it' fine with that one. The problematic board doesn't respond to M42 P27 S0/1, the output doesn't change its state.

Hello

I have a DueX5 board. Recently D5 Motor driver stopped working, other ones are fine. I have verified it replacing a motor and a connecting cable and still D5 is down, other drivers work correctly.
