6XD I/O >> Issue solved

tecno

Regarding outputs 3 4 5 and 8 = not working at all!

Done following Change
;***Outputs
M950 P0 C"out0" ; Q500 ;#1 Nozzle Vacuum
M950 P1 C"out1" ; Q500 ;#2 Nozzle Vacuum
M950 P2 C"out2" ; Q500 ;Drag PIN Actuator
M950 P3 C"out3" ; Q500 ;ENA Nozzle 1/2 Up
;M950 P4 C"out4" ; Q500 ;Xross cursor
;M950 P5 C"out5" ; Q250 ;LED light
M950 P6 C"out6" ; Q500 ;Vacuum power
M950 P7 C"out7" ; Q500 ;Xross cursor
M950 P8 C"out8" ; Q500 ;LED light

Tested first to move #4 to #7 and voila the xross cursor works with on and off.
So next #5 to #8 = NO GO
Changed #8 to #7 and the LED Lighting works.

So now it is time to get this 6XD on WARANTY A S A P

@tecno I suggest that you test the outputs on the actual 6XD. In all the previous 100+ messages in this thread, the fault has NOT been the 6XD, it's been the wiring. I assume that you have tested this by moving connections on this switching board, rather than testing the outputs on the 6XD:

There's a ribbon cable between the 6XD and that board. Have you tested the continuity of that? Have you tested that there are no failed components on that expansion board on these lines? After all the previous issues, I very much doubt it's an issue with the 6XD.

All testing is on 6XD

The picture was to clarify port 4/5 to be the only way to switch off 4 and 5 loosening cables!

Pls explain why #8 works on #7 if it is as you claim to cabling issue!

Far too many issues points to a faulty 6XD.
Been setting up 4 machines with Mini 5+ and this one is giving one more gray hair!

droftarts

@tecno Every issue so far has been fixed, and has not been the fault of the 6XD. As for grey hair, you've given me plenty.

Have you checked the macros or commands you use to turn the outputs on and off refer to the correct pin?

I need to see how you're testing the outputs on the 6XD. Ideally, with a multimeter, test for voltage between the V_OUTLC# pin and the out#- pin, of each output. You should get no voltage when it's turned off, and should read the voltage of the V_OUTLC# when turned on. Repeat for all out# pins.

You should do this from a fresh restart, so the config.g is applied. Note that you currently have out4 and out5 commented out.

If there is an output that is not working, please post the full config.g that you used to test, and post the macros or commands you are using to turn these on and off. Also post a good image of the area around the fan outputs, which should show if any of the MOSFETs that control the out#- pins has been damaged.

Nice with grey hair

Yes all macros checked as regards command and pin#
M42 P3 S0
M42 P3 S1

M42 P4 S0
M42 P4 S1

M42 P5 S0
M42 P5 S1

Tested with DMM and 3-5 works as you describe BUT connecting LED Light on say #5 it is permanently ON so as I see it there is something wrong. Connecting the LED Light to output 7 or 8 I can switch on and off.

@tecno Those results don't make much sense. You said out4- and out5- don't switch off, and out8- doesn't switch on.

I think you're saying the results of your testing are:

Multimeter test: out3-, out4-, out5- test correctly. Do out1-, out2-, out6-, out7-, out8- respond correctly? I thought out8 was the problem?
LED test: out5- is permanently on. out7- and out8- test correctly. What about the rest? How are you connecting the LED? Between a V+ pin (whatever voltage the LED takes) and the out#- pin?

So out5- is the only one you tested with both tests? And it works okay with the multimeter test, but not the LED test?

Please post a picture of how you're testing with the LED, on a pin that's not working, so I can see the setup.
Please post your config.g, and all the macros you are using to turn the outputs on and off.

Outputs 0 1 2 6 7 8 OK
Outputs 3 4 5 the Led light is not controllable and always on.

@tecno So in the first picture the LED doesn't work, connected to out3-, but in the second picture it does work, connected to out8-?

And you're not directly connecting an LED, you're still using the breakout board?

@droftarts

3 4 5 behave the same. Does this anything with V_OUTLC1 and V_OUTLC2 to do?

tecno

@droftarts

Not a breakout board.

YES IT DOES !!

@dc42 @droftarts

Possible to concentrate on VACUUM sensors?

Care to explain? I didn't even think you were using the V_OUTLC pins on the fan headers.

So they are all working now?

@droftarts

As 6-8 works with V_OUTLC2 I tried to same setting for 3-5 and now it works.

I did wonder about that myself, but didn't think the voltage on V_OUTLC1 or 2 would matter. However, looking at the schematic of the 6XD, it does:

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)!

@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.
