Print start without setting temperature of Bed and Nozzle

What is the problem?

When I start a print using Prusa Slicer and Octopie on my Raspberry Pie 4+ who has 4 Gig of Ram, the first command are

M107
M190 P65 ; set bed temperature and wait for it to be reached
M104 P215 ; set temperature

It never set the bed temperature neither de nozzle temp. If I try to send the command via the Terminal, it does not work has well. I can send other command and they work fine.

What did you already try to solve it?

I try in Safe Mode and Normal Mode. I update via ssh connection the firmware of the Raspberry Pie. I try to update Octoprint even if I knew I had the Last Update via this command : 1. ~/oprint/bin/pip install -U octoprint.

Have you tried running in safe mode?

Yes without success.

Did running in safe mode solve the problem?

Nope

Could you share the gcode file?

Another good thing to enable is serial.log, under settings > serial connection > scroll to enable serial logging.

Then start the print again, find the problem and it will be captured in the serial.log file. Please upload this here.

Thanks for the quick answer

This is the serial log that I have when I do a M190 P65

Complete g-code file is attached but since it doesn't work in the Terminal window, it is not working when trying to print as well. Command to move axis, command to print are working.

Forget to tell that I reinstalled Octopi to my raspberrypi from scratch before trying again.

SmartTemperatureTower_PLA_Plus_195-235.gcode (2.1 MB)

Could you please attach the complete serial.log as file? Thank you!

Curious is, that the printer firmware does not register the heatbed temperature of 65°C.
It stays at 0°C (= off)

Can you set the temperatures at the printer's menu panel?

Ok. I found the problem.

When I created the Octoprint printer in the Prusa Slicer, it defaulted the G-Code flavor to MachineKit. So it didn't put the right command for the Set Bed Temperature and the Set Nozzle Temp. So my print was starting immediately and the temp never changed.

So if you use Prusa Slicer, look for this G-Code Flavor. It needs to be set for the Printer and for the Octoprint Printer as well

Thanks for the help.

Daniel
