SnapMaker 2.0 Connection Errors

I’ve read a few posts on here from fellow snapmaker users and As a snapmaker 2.0 user myself, and an embedded developer, I can say that connected mode does not work with the snapmaker 2.0 A or AT series printers. The issue isn’t with the OS or Docker though, it’s the connection through NodeJS and the associated code. I’m looking into a fix for this myself, but if someone else beats me to is, Here’s the error below. I can provide whatever info is needed to help troubleshoot this if someone wants to colab on it also. The quicker it gets fixed the better in my opinion, it is afterall listed as a supported printer….

New Request: connect

--origin: simcoe

Ok, So I spent the afternoon debugging this and was able to get it connected to the snapmaker 2.0 A350T here’s the connection output below. Temp and all the controls work now. I used a workaround to get this up and running, but I don’t think it’s a good “permanent” fix. Also, that isn’t my job after paying $$$ for this thing, but here’s the thing you couldn’t fix for the last….however long. So that’s where you come in Mosaic, I showed you the issue, please release an update to address this for all the Snapmaker Users (while I enjoy printing in connected mode now).

The issue is for some reason, the controller.sendAndListen function returns an error even when it’s successful. I got this working by removing the else from the ‘else if’ statement at /app/src/printer/actions/temperature/getTemperature.js:58 so that even if there is an error, as long as data is present it’s still returned. The error so far hasn’t affected anything but connection. It may even be timeout related, I admittedly didn’t look that far into it. After staring at code all day for my job and then this, I’m a little burnt.

PS- You’re welcome!

Hi Jared,

Thank you for sharing this with the community! I will have our software team review this. — Hana
Thanks @hana. Testing it combined with the update that was released today and it's working well. Printing a few clownfish right now, I'll share later. Haven't had any connection issues, only splice breaks and did some tuning. — Jared
@hana I'm happy to test any changes the software team makes with the apollo server code if you don't have a snapmaker printer available for testing. — Jared
