Nothing in the firmware. It’s all commented out for the maxtemp variables.
But I found multiple references to this limit on various forums/websites. There must be a maximum set somewhere in there via electronics. I’ve never tried 265 before…
I can now confirm that temperatures are dropping below 260 as it progresses. So definitely an internal cap at 260C.
Regardless, I think you’ve solved my other issues. A big thank you. Looking forward to learning more using Kiri:Moto. I’m a fan. Just a matter of learning how to leverage it well.
Writing this here on top of emails so others can find a conclusion in the future.
