Heater issue: Heater extruder not heating at expected rate
You need to change the sensor pin in your printer.cfg file. Check the datasheet of your board (I have a BTT Octopus), and use the name of the new port where you connected your thermistor.
In my case looks like this:

Yes, you will need to change the sensor_pin in you printer.cfg so it points to the new connected pin in the board

Heater issue: Heater extruder not heating at expected rate
@topchicken6277 I've just made the change on the heatbreak and seems it's working fine now. To verify that it was indeed fixed by changing the header in the board I've kept the thermistor that I had earlier. So now it's not doing strange things with the temps and prints fine. 😄

Heater issue: Heater extruder not heating at expected rate
I think it fixed it but I cannot confirm yet. After changing the thermistor to another header the pid and the heating seemed to be stable, but I found out that due to the temp rising a lot some of the PETG parts of the hotend support started to melt and led to my hotend crashing against the bed, breaking the heatbreak.
I had no time to check this until yestersay and I'm getting a replacement tomorrow. I will try to update as soon as I make the change and see no issue here.

Heater issue: Heater extruder not heating at expected rate
I've just made the change and I'm running again a PID tunning and some more tests after. I will update it with my findings.
Thanks for the suggestion. As I have been tinkering with a different board this past weeks I totally forgot that the octopus has 4 slots for thermistors 😄

Heater issue: Heater extruder not heating at expected rate
For reference: the printer was able to start now a new print, but something's not right with the temps, as it went up to 265 after reaching hotend temp and I can see that there is indeed a lot of stringing and blobs in the printing (see attached picture)

Bed mesh not working correctly
Yes, but I'm checking the whole XY mechanism because I first had an issue with the X rail not being 100% parallel to the frame as I did not tight the belts correctly and it was not mounted correctly, so there was a bit of a gap

Bed mesh not working correctly
I'll check first thing tomorrow morning the gantry and probably will remove the entire rail to further inspect it. For now I was able to check the hotend carriage in case it was not tight enough but it doesn't seem to be the issue, as I still have that same weird mesh.
