@dc42 Thanks for the reply, I figured because the LED is continuously blinking, the "board is running but does not have CAN communication with the main board". But shouldn't it momentarily stop blinking when it's being reset?

Hi all,

I've recently gotten a Duet 3 Tool Board and it seems like when I power it on using 18V power supply, the status LED blinks in red, indicating it is running but not connected to the motherboard. However, when I try to reset it by pressing button 0 and button 1 during power on, the red light keeps blinking without showing any signs that it is resetting. Is it the board being faulty?

Thank you!

@o_lampe I see, thank you so much.

@t3p3tony So the timeframe onto which the input/output should be aligned is in 1 ms units, but at this moment I've yet to test how sensitive the input/output relationship will be by changing the precision of alignment..

@chrishamm Thank you so much for the reply. So to be precise, it needs the "sending command" and 'receiving data" tasks to be aligned, so that some input/output relationship of the printer dynamics can be computed (either in real time, or after some time delay). So do you mean it will be hard to do both "sending" and "receiving" in the board to compute, since the received data may not be exposed via object model, so it needs some conversion post-processing to do computation on the data afterwards?

@t3p3tony Thank you so much for your reply. So actually we've considered using RPi but the thing is that our motion command data and accelerometer data will need be able to be aligned so that some input/output relationship can be computed (and yes, this data collection only occurs during a set of test moves, not for every print). Using RPi to do this, it may be a little bit hard because there is no absolute timestamps on the data/command to align.. or is there?

The ideal case would be if the input collection and processing can be done on the board, at same sampling frequency, so that this aligning process is smooth. But if not, do you think there's another way to align this using RPI?

Hello,

I have a few questions on the capability of Duet Wifi 3 board!

Right now, I'm trying to:

1. control a 3D printer with it using a pre-computed set of X, Y, Z, E commands
2. get data from accelerometers which are attached on the printer.

Here, the two tasks will need to be synced at a fixed frequency and also will need to be simultaneous, which I know is possible with the Duet Wifi. My question is, is it also able to store data within a certain timeframe after a command has been sent, AND process the data (e.g., plot the data ) while send/read tasks are still in progress? If so, how much storing and processing can be done?

Sorry if it's a basic question... I've been looking at the datasheet but I'm not sure how to find the information I'm looking for.

Thank you so much!
