Solved M303 - failed to read sensor error

[vbtalent2]

Just getting my printer out of storage and having some configuration issues, at the moment with tuning the Heaters.

Long story short... everything was working fine before being put up in storage.

After pulling it out of storage, I had to upgrade the firmware to 3.35 and create a new config file, The current problem I'm having when running M303 autotune is the following error...

I checked the heater resistance and it falls in line with a 24v E3D so I don't think that is the problem.

This is the original config.g that was working:

and this is the new config from the config tool:

Hoping someone might see an issue or setup problem...

Thanks for any assistance you can give.

@vbtalent2 you'll find the M307 details here

@vbtalent2 you should probably be using e0temp and e0heat and not e1temp and e1heat

@jay_s_uk thanks for the reply.

Noted e0temp and e0heat.. thank you.

May I also ask about M307... RepRap doesn't even identify some of the parameters being generated by the config tool, curious why that is and what they mean?

My old config file wasn't using them so looking to understand..

Just wanting to close the loop on the subject and let you know that your suggestion was right on... I was able to run autotune on both the bed and hot end after making the config changes.

I am still a bit curious about the M307 parameter if anyone knows them.

Many thanks for the input.
