OctoPrint Error with start Temp under 10°


#21

Either firmware or wiring. Or just temperatures :wink:

@foosel Octoprint ist der Hammer! Sehr geil gemacht! Vielen Dank.
Octoprint is a great product.
I am coming also from a development background and I am sorry to say it but your are only partly right. I went through the errors and normal terminal messages in the last days. OctoPrint is just not able to display temp with less then 10°. I thing the label and the Temp chart are expecting a three digit temp. (XX.X and not X.X)

Update from today surrounding temp 3° when connecting to the printer:
Terminal giving at the end this Error:

I could solve the issue with the octoprint setting in the second state at "Verhalten" were it is not killing the connection to the print. It would only to a current print. So I am able to set the temp and warm up the bed and the nozzle above the Mintemp (which must be between something like 5° to 9°)
So the Error might be triggered from the firmware but is neg liable.
But the temp chart and the labels of octoprint are not displaying temp under 10° even there is no Error. This would be nice if it could be changed, but as I now it from my clients,

I think am a very rare case so thank you all for your support. It help me a lot under standing the messages and how to find a suitable solution :slight_smile:

It is able to just fine. But the temperature tab simply considers anything less than 10° as "off" for display purposes. Seemed more practical that way.

Doesn't change though that that Error: is triggered in the firmware, not OctoPrint. OctoPrint is just displaying it. Note how it says "Recv" = "Received" in front. Your firmware decides that less than 10°C is not a viable temperature for your printer (or that your thermistor is broken), triggers that error and locks itself down. This is not OctoPrint doing that, it's your printer.

edit actual temperatures below 10°C will be displayed with their value instead of off starting with 1.3.11 to prevent anyone from thinking that the temperature graph and the firmware triggering mintemp are related :wink:
