IS Plugin

Sorry for the Bad Picture Quality

The plugin behaves here correctly as the file reports a sample rate of zero. This is why only zeros are displayed. I am not sure why RRF reports a sample rate of zero despite recording all those samples.

From https://forum.duet3d.com/assets/uploads/files/1633689320062-20_2021-10-08_12.32.09.csv:

998,-0.031,-0.125,1.039
999,-0.031,-0.125,1.039
Rate 0, overflows 0

@heartleander81 did you resolve this issue, or are you still getting only zeros along the bottom of the plot?

Heartleander81

@dc42 There are still zeros displayed. Unfortunately.

Another user reported a similar issue.

@mfs12 I have See it, thanks.

Good Morning.
I have now updated to 3.4 Beta 6 and Pre 7.
Unfortunately the problem that the frequencies are not displayed is still there.

@heartleander81 please can you attach the latest .csv file that was generated when you ran the IS plugin.

@Heartleander81, i added now an option in the "record tab" to not delete the generated files by the IS plugin.

@mfs12 When I look at the IS file in the Duet accelerometer, it shows frequencies.

mfs12

for some reason your device report a rate of 0. which is strange and causing the problems.

Heartleander81

@mfs12 OK. What could be the trigger for this?
Is there a way to do tests to find out what might be the cause?

dc42

@heartleander81 I am still trying to work out how this could happen.

@Heartleander81 I've managed to reproduce this by disconnecting the interrupt signal from the accelerometer. So I think your board has a hardware fault. Which revision of tool board is it? If it is a rev. 1.1 board, does it have a diode soldered on the underside in one corner of the board?

dc42

@heartleander81 I've added a test of the interrupt line in the firmware:

Please install the tool board firmware from https://www.dropbox.com/sh/wtgcvkuaq52x3aq/AAADVEzSwypcIZSwExX0M4RQa?dl=0 on your tool board. It is compatible with 3.4.0beta6 main board firmware.
When that's done, send this command to attempt data collection: M956 S1000 A0
If that command reports failure, run M122 B20 to get the tool board diagnostics.

@heartleander81 thanks, that shows that the INT1 signal on your board is not connected. Please email warranty@duet3d.com. Although if you have a v1.1 board and a soldering iron, you might want to check visually the soldering of that diode first.

@dc42
Ypu mean this ? I can test to soldering
