So step 8 is connecting via wifi

1. your computer is on WiFi, do you have a list of access Points?
2. If so do you see the Duet an access Point? If not, are you seeing any access points?

Thanks David, so I will need to wait for the next firmware to get wifi status.
Great to see this feature in in development.

Would reinstalling the wifi server firmware have any impact on reducing the failure?

Is there an M command that provides feedback on whether the DuetWifi is connected, ie the IP address.

I'm finding that on boot up, DWC doesn't find the fixed IP address that I've set up in the router. Going through PanelDue i've found that typing M552 S0, waiting a min, the M552 S1, DWC will then find the printer (works 80% time). Redoing always fixes it.

I'd like to run a command to check what the state of the connection is, via the PanelDue - is it possible?
I don't have a pc near the printer.

I know the WiFi signal is OK, as my IP webcam that sits next to the printer works fine.

I had nearly exactly the same issue, and I started discussing on on reprapforums:

I fixed the issue by downloading a new configuration file (using exactly the same parameters). I've no idea what caused the first problem.

I found it easier to just drop the firmware in the directory where bossac is, navigate to that directory in the cmd line and then type the code to run.

These piezo's are tough units (using 27mm). In fiddling around, the + wire became detached from the centre (pulled the white stuff off)- thought I'd reattach/solder and hope. Well works fine!

After some more meddling, I am now getting really good results.

This is the best bed mapping that I've ever had on the printer since running duet wifi.

It's the probe…...

Its amazing what a day away does…

Nozzle diving below print bed - problem solved.....

Given it was probing nicely, turned my attention to the G-CODE file.

G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 X0 Y0 F6000 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops

Removing the G28 Z0 from the code seems to fix it, and it prints at the right height. Now I need to figure out why......

@DjDemonD:

I've only skimmed this a bit tied up, but do you need the H2's in your bed. G?

Edit Yes I suppose you do, I haven't used RRF on a cartesian machine. Hmmm…

Not exactly on topic but have you tried the probe on digital instead of analogue, with low debounce value? You can probe at a higher speed with no false triggers.

I posted my M558 and G31 on a previous page.

I removed the H2 and the auto bed compensation graph was higher, but still under z0. Did a probe, which still showed as also under the bed, went to print and the print head wants to start at somewhere around z-5.

Had enough for today. Will try digital tomorow.

adding G31 Z-0.2 or G31 Z0.2
or extremes like G31 Z-4 or G31 Z 4

into the config.g file has NO impact whatsoever.

I'm stumped.
