6XD I/O >> Issue solved

As the LEDs connected to OUT3_NEG are powered from 24V, but VOUTLC1 was jumpered to 12V, then the LEDs will get around 12V even when the port is turned off, which is why they stayed lit. I'll have to remember that. Presumably you jumpered both of them to V-FUSED, which is 24V?

Anyway, another problem resolved without recourse to a warranty replacement (which would have exhibited the same problem)!

I am happy as well.

@tecno That board is effectively a 'black box'. You could try powering it up, and see what data comes out of RX/TX, but I think it's going to be difficult to integrate, and easiest to just replace.

Google-ing that pressure sensor shows it on a breakout board that can connect to an Arduino: https://makersportal.com/shop/mps20n0040d-ported-pressure-sensor
The output is an analogue 0-5V, so would need to be converted to 0-3.3V to be read by a Duet input. Fortunately this is quite easy to do with a voltage divider circuit, eg https://randomnerdtutorials.com/how-to-level-shift-5v-to-3-3v/. Then define it as a "linear-analog" sensor in M308.

Google-ing "ported pressure sensor" shows that Adafruit do one that uses I2C: https://www.adafruit.com/product/3965
I haven't looks closely, but this might be simple to integrate using M260. Don't use long cables with I2C, it's quite susceptible to noise.

Sparkfun also do one: https://www.sparkfun.com/products/16476. Other ported pressure sensors may be available.

The board was working OK with original controller.
The RX/TX signals are 5V on this board, I have bi-dir levelconverter.

Is this the correct way to setup a second com port?

I guess they got to write the firmware to support it.

As far as I'm aware only IO0 and IO1 can be set up as UART. See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview#specific-capabilities

However, I highly doubt that it will output anything the Duet can understand. The PanelDue sends Gcode commands, either to control the Duet or request data. Same for devices connected over USB.

I'd try hooking it up to a serial to USB converter, and plugging it into a serial terminal on your PC, to work out what it's sending and if you can control it, then work out if you can use it with Duet. M260.2 and M261.2 might help.

Are you developing this as a commercial machine? Because I feel you should be paying for this level of support.

Thanks for the information Ian, will try to hook it up and see what it does.

Commercial = NO I'm 74years old fart playing around with some toys.
