Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

printer worked perfectly 2 days ago

Hello @wormpower!

Lets see why OctoPrint is not printing.

It occurs, that the printer does not heat up.

For you do not set temperatures to either bad and extruder, it will not heat. Also if there would be a value, there is no waiting for to reach the needed temperature.

Have you recently changed your slicer?

Hello @vbbartlett!

Please don't hijack a thread with a different problem. It seems you have connection issues.
@wormpower obviously has a slicer problem.
Please open a new thread and fill in the template that appears.

I haven’t changed anything.
I’ve tried to set temp in octopi then hit print. Temp stops heating.
Tried printing via saved file in octopi, or from cuta.
It always ends up with printer canceling.
No update to cura. And no change to file

Please don't mix up OctoPrint and OctoPi:

You may use M109/M190 instead of M104/M140 because the first ones wait until the temperature is reached. And don't forget to set the proper temperatures to these commands.

Can you share the start gcode you use in cura?

i was mistaken, there was an update to cura
but below is the updated terminal output

From the post before I can say, that there is no heating established.

You may preheat from OctoPrint with this:

You also can use the Preheat plugin:


This takes the values from the file that is to be printed.

@Ewald_Ikemann
i tried preheating with both methods
as soon as i print it kills temp

Because in this section you set the temperature with the value S0 to 0 (zero) again.

i didnt change it, it changed as soon as i hit print

What is this short 6 liner you want to "print"? There is nothing to print in it.
I just looks like an End Gcode script.

sorry i dont understand this question, im still pretty new to gcode.
below is output from hitting print in cura, uptill now ive been hitting print within octoprint

So I recommend this site:
https://www.reprap.org/wiki/G-code

With this you can "decode" the lines of a Gcode file.

Actually, the file you want to print contains no data that can be printed.
You can recognize them by a G1 at the start.

Have you tried to slice your model again?

@Ewald_Ikemann
this is a fresh slice

There is still nothing in it.
Maybe the model is broken. You may try another model.

Or somthing is messed up with your Cura settings.

@Ewald_Ikemann
this is a different model

There is also nothing in it.

Have you checked the Cura profiles are still correct?

@Ewald_Ikemann
firstly thank you for trying to help me
sadly i created a new cura profile and still doesnt work.
2 days ago it printed the files in octoprints file history.
not changed anything between then and now

As long there are proper files on OctoPrint, you still can print them
