HTTP 400 when attempting to print

[ixtenebrae]

Hello, I just got everything set up and seemingly working. I did have some stumbles when I first got it all loaded. I was getting HTTP error 500 when trying to access the main page. Little did I realize I didn't add in the uart enable line. But once I got that corrected and restarted, when I attempt to print from the web interface I get an HTTP error 400. My journalctl shows this:

Not seeing a whole lot that tells me anything.

Starting the print manually does result in the web interface showing the status of my print. My first thought of the serial connection having issues tells me this might not be the case. I did test the cable I made and had continuity at both ends.

Edit: I spoke too soon. When I went back to the web interface after the initial layer, it gave me an HTTP error 500.

Next update:

Wiped everything out and started clean. Now I was able to get the home page to load and even initiate a print, but it seems once it went beyond the first layer, the home page errored and wouldn't display the status. But, the print is humming along. Here is a complete log from reboot:

These errors indicate that the end offsets for each layer are not matching the current byte being reported by the printer. This is either because we are parsing the uploaded file incorrectly or because the printer is reporting them differently from other printers we've seen for some reason.

Which files did you upload? Does this reproduce with any file you upload? Can you share one? Which printer do you have?

If you can, it would be interesting to know the value of sliced_model_file.end_byte_offset_by_layer here: https://github.com/luizribeiro/mariner/blob/master/mariner/server/api.py#L60

I can't believe I didn't even mention the printer. It's an Elegoo Mars. 2nd gen without the ethernet port.

It seems to be with any file I've tried. I'm attaching some samples of non-purchased stuff.

I'm rather new to Python so I'm trying to puzzle my way through the code to see if I can be of more help. I might see if I can set up something simple to just monitor what's going on the UART and see if I can figure it out from that angle. This is a cool project and I'd love to contribute any way I can. I have some research to do.

Thanks so much for your help.

It seems everything is working once I changed the serial options in raspi-config. I've been playing around with screen and I'm able to send and receive commands, so everything seems to be working properly now.
