The duet stop printing but the script continue

chrishamm

Many thanks for reporting this, I've just reproduced and fixed this problem. It will be fixed in the next version.

Donpi

Are there come log that I can check to see what is appening in the Duet ?
Or what gcode is effetively executed .

TBH I had some problems with your plugin but I've got a fix ready - at least I haven't been able to reproduce it with the latest dev version. This problem only showed up when two G/M/T-codes from two different G-code channels were frequently sent.

To work-around this problem try to send your M106 code to the File channel (that's the same channel used for file prints) and consider adding a delay (e.g. await Task.Delay(1000);) after it. The second parameter of PerformSimpleCode lets you choose the target channel.

Donpi

@chrishamm Great, I'll test that today.

I thought I was abandoned alone with my problem

Donpi

@chrishamm said in Duet 3 +SBC : Print randomely freeze when runin my script on RPI:

await Task.Delay(1000);

The workaround seems to work but it gives me many "Error parsing response" in the PanelDuet console

chrishamm

@Donpi I tested your plugin with 3.2-RC1 and I no longer get unexpected crashes or other problems. In any case I recommend adding a short delay once object model updates have been received to reduce the CPU usage a bit.

Donpi

Good to hear that
Thank you for the support
