Input Shaping Board shutdown during messureing
-
Hello,
I have a question about input shaping.I have an Adafruit LIS3DH sensor, wired and configured directly to my Duet 2. The sensor is also recognized (green light).
However, as soon as I want to take a first measurement (via the plugin or console commands). The measurement process aborts with the message "Measurement aborted" and the board restarts completely.
The cable used is a multiple shielded one, the shielding is also grounded.
Duet Firmware is 3.4.1 // Input Shaping Plugin which is 3.4.1 b1
Does someone have an approach for me how I can solve the problem.
-
How long is the cable? Where is the shielding grounded to?
Can you gather a M122 report after the board has restarted? -

Hello,The cable is a USB 3.0 Cable in 1.5 Meter. Also tested with 0.8 Meter. And also testet with unshielded Cable.
The Shield is grounded at GND on the Duet Board an other side GND on the sensor.
āāThe Test Prozedure beginn normaly, because stops with the failure an shutown the board.
CSV Files are written with nothing inside an get a parsing failure.
Here is the M122, with no Sensor Connected (the Printer Runs currently)

EDIT: Nevermind, i didnt read the entire thread before posting it looks like you already have the USB3.0 cable. sorry i dont have anymore more to add.
@michaelkallner I was having a similar issue the very first time i connected my LIS3DH, the board would restart every time i tried to take a measurement in the plugin. But i dont know what i did, the issue never returned. I have since changed to a USB3.0 wire as someone else gave me the link, so I pass it along to you in case it might help.

Do you have another accelerometer to test with?
Can you show some photos of the wiring? -
@phaedrux
Hello,I'm sending the pictures, I hope that's enough.
I tested a 2nd sensor. Also on another printer with the same result.
With a third printer I get an abort with the message INT1 error.
Verkabelt ist es wie im Bild:
-
I can recommend adding a 1k resistor to SDO close to the sensor board which may solve capacitive coupling between SDO and CS.
-
@phaedrux
Hello, many thanks for the answer. I'll test that once. can you dare tell me how many watts the resistance must have or is that not important for this purpose? -

@phaedrux
Hello, thank you very much for your help. Soldering the 1K resistor directly in front of the sensor board helped. I have a stable signal. Tested several times, flawless. I also think that the connected shielding also helps.Thank you again.
