Time to get out a USB cable and get FluidTerm connected. We need to see FluidNC log output and $SS to try and understand what’s wrong with your setup.
Do you have another device you can try to connect with?
I reinstalled FluidNC version 3.9.1 from another computer and was able to access it via Wi-Fi using Chrome without getting the error. Everything works except the Z axis, which still doesn’t respond… I tried swapping the drivers and motors for the axis, but it still doesn’t work… I ran $SS and nothing seems out of place… I’m pasting it here in case you see something that might not be working`

At the same time or one at a time?
If you look at the underside of the jackpot where the z0 driver plugs in can you see any visible defects? Do all the header pin pads have clean solder on them?
Or if you prefer to, take some clear photos of your board, both sides. Upload them and we can take a look for anyt;hing out of place.
If it’s never worked from new it could be a manufacturing defect I suppose…
There is a spare driver slot, it’s possible to use that as z0 but you should be able to return it to elecrow for a replacement.
I don’t see any apparent defects on the board. I’m attaching some photos.
How can I change the configuration to use driver slot C instead of Z?
Make sure you have a copy of your config.yaml.
Here is one I changed to use C for your Z0.
config.yaml.zip (2.0 KB)
In the end, it worked by switching the Z driver slot to C. It was my last test to try. Thank you so much for everything. I’ve already started calibrating and loading some job files, and so far, everything is working great!
