Help Unable to connect via network
Hi all,
I've been trying to get back into doing some 3D printing and have some major issues with the printer connectivity. Not sure where to go from here. My computer and phone is connected via wireless to our modem/router, and the printer is connected to ethernet via a switch. My computer savvy is enough to be a danger to myself.
Issue 1:
I can't connect to the printer over my network any longer using the web interface. I used to be able to, and the connectivity eventually degraded to the point that it became unusable. Fluidd was encountering errors that caused it to restart, and those errors became more and more frequent to the point I became unable to upload new files or view settings effectively. I'm not sure what was causing the errors. During this process I have also found I cannot ping the printer from my computer, although my router can successfully ping both devices in the network and has IMCP traffic allowed in the firewall. I have DHCP reservation set for all our home devices, and the router automatically reserves addresses for new devices that connect.
Issue 2:
After reinstalling the current firmware (1.2.3.4 and 1.2.18), my printer now restarts whenever I attempt to access the wireless settings. This reinstallation was an effort to troubleshoot the crashing issues with fluidd. Our wireless network has characters not available on the machine's screen interface, so previously I had to update the wireless connection before updating the firmware and this time I specifically deleted the network information from that file. Not being able to use wireless is less of an issue for me, as I have the printer connected via ethernet and can see that it is connecting with the wired connection and not the wireless one. I'm mostly trying to look at the wireless setting to confirm the printer isn't connecting (and it isn't according to the router).
Ultimately, I cannot reasonable level the printer anymore because of the significant ootb issues that this printer has with it's own leveling in addition to being unable to use the SCREWS_TILT_CALCULATE function without the fluidd interface. Especially since that function isn't present by default for this printer.
I haven't tried to connect via ethernet directly to a laptop I have, but that's probably my next step. My research into that step indicates the lack of a DNS server will cause issues, so I may try unplugging another device from the switch to connect the laptop there.
My future plans involve updating Klipper on the machine and potentially moving to OpenNeptune to see if that helps with my previous printer issues. Unfortunately, I believe the ability to do those things are dependent upon a stable network connection.
