Bed Temperature changes

What is the problem?

i start a print with 70°C Bed Temperature, but the bed heats up to constant 80°C

What did you already try to solve it?

Check G-Code, start several prints, checked settings in Cura and OctoPrint,
Installed OctoPrint brand new

Have you tried running in safe mode?

No, but i dont have much plugins

Did running in safe mode solve the problem?

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Have you done something on the settings in the temperature tab?

grafik

Almost as much as built in plugins...

These are in the systeminfo bundle

Thanks for you fast answer.
I didnt do any changes in the temperature tab

Can you take a screenshot of the temperature graph which shows the 80 degree temperature?

The .gcode file you uploaded contains only commands to set the bed to 70 degrees at the beginning and 0 degrees at the end.

I suspect that the PID values for the bed are wrong but since this is a Creality printer, anything is possible. We should be able to help you tune the PID values after we see the graph.

PID seems to be fine.
It gets the target temperature.
But as soon as the nozzle is at target temp, bed temp gets set to 80°C

Whenever i try to manually disable the target temp, it gets set back to 80°C

This seems to be different for the gcode file you attached in your first post.

Here the extruder is set to 230°C, in the gcode file just to 225°C.

correct. differect gcode, but same behaviour

8

So, meanwhile you ran safe mode?

It has not to do how many plugins you , but what plugins you have.

I started in Safemode - Same behaviour.
What i noticed: Temp of bed is fine, then printer does Homing, where it sets the temp to 80, but does not set it back to original temp of 70.
Seems to be a problem of the printer?

This is strange, how does the printer make a G28 into M140 S80 G28....
Does your printer have a 'smart/touch' screen? Smart screens are actually 'hosts' with their own programming.

Good question.
My printer has a touch screen.
I googled a bit: Looks like for my printer it is needed to set BedTemp after homing.
So i will adjust the start G-Code tomorrow and add some M140 after homing:
G28
M104 S{material_print_temperature_layer_0} ;new!
M140 S{material_bed_temperature_layer_0} ;new!

12

That worked!
Setting the Temps after the G28 did the job.
Thanks for the help, although it wasnt a octoprint topic

LOL It rarely is...
