No printer Status displayed

[jeffdavis503]

Description
After a complete install of the latest and upgrade of Python the Mariner3d.Service starts but when I browse to the server I get the unexpected response '0k N:0\r\n' message. But after I click OK to remove the dialog the Printer Status just shows a spinning circle even though the printer is printing . I have an Elegoo Mars Pro 2 with the latest firmware.

I am able to upload files. And the browser does show me the files and preview them and I presume start them. Although I haven't tested the starting since the status isn't showing for printing in progress?

Reproduction Steps
Steps to reproduce the behavior:

1. Go to http://X.X.X.X:5000
2. Click on OK after message dialog displays
3. Screen shows blank printer status

Are you by any chance using Lychee Slicer as this has started happening to me too.

[jeffdavis503]

Nope. Chitubox 1.9

Any suggestions? I'd like to start remotely monitoring my printer. It took me months to order a Raspberry Pi Zero due to stock issues. I've soldered on 3 pin headers to the TX, RX, Gnd pins on the motherboard of my printer with a cable coming out the back. I've printed a Pi Zero case with my printer. I've loaded all the software and updated the Python version to get it working. It took me a while to get to this point. I'd really like to finish the project and start using the software.

Still haven't found a solution to my problem. Any help would be appreciated.

Depending on your printer and the board firmware it's running could have something to do with it. I have a Saturn S with firmware 5.5 and used .CTB v4 with encryption. When I load one of these files into the USB share of the raspberry pi mariner3d acts very similar to your issues. If I remove the file mariner3d behaves correctly. There are some branches working to correct this issue and hopefully when a fix is available they will add to the public release we all use.

Ahhh. Makes sense. I will find the setting in lychee to prevent the v4 export then.
