Hi everyone, I am new here and new to 3d printing. So far, I have done the bench boat, the XYZ cube, and a trash can for all my failed PLA to go into =D. By day I'm a retired IT professional in the cloud computing, DevOps arena and am fluent in Linux =D. So I'm not afraid to get my hands dirty.
I have the latest octopi installed. I have an Ender 3 Max Neo.
As the title suggests, octoprint is installed. DNS works, and everything is fine, except it cannot talk to my printer.
The error message says it failed to write to the serial port.
I looked at tons of YT vids for answers. I have checked the known issues w/regards to the USB powering thingy. The Ender 3 Max is not listed as having this issue (however, I will be buying a Power Blocker Dongle here today ... just in case.) So far I have found zero online references to people w/the ender 3 max having issues with serial connections over USB. I saw where this one guy opted to install some henky-looking USB drivers to solve some issues related to usbserial connections. That didn't work for me, either. I eventually deleted the octopi install and reinstalled the OS for a clean install.
I have also run upgrades to the os software (using apt).
What is safe mode? Is the printer in safe mode? Or the pi? I'm confused.
