Could not replace C:\Users\Kalle\AppData\Local\Temp\build8185119812540562095.tmp\ConfigurationStore.h

is the error i’m getting when trying to up my new firmware. Looks like it’s trying to access a C drive location rather than my USB port 6 location.

How do I get Arduino to upload to the 3d printer? Pronterface sees the printer and connects on port 6 at 115200 BR so I don’t understand why Arduino isn’t seeing the machine board.

Help would be really appreciated for what is likely an easy answer. TIA

This is an error writing to your temp folder, something the arduino ide tries to do before uploading to your board.

It can be a pain to track down. It could be a corrupted file in temp, write permissions, or you do not have the marlin software properly installed, and a host of other things.
