    • RE: Duet 2 WiFi wifi dead

      @bearer It could have been a bit longer but I tested for continuity between each leg and the pads on the front and back the best I could. I'm going to try and hunt down a spare wifi module just in case 👍

      Thanks! hopefully, it will keep going now. I examined it close up and couldn't see a bad solder joint so I'm guessing it was bad solder somewhere in the module.

      I managed to fix for now I masked around the wifi module with Kapton tape and gave it a blast with a heat gun for 2 seconds. I've handled it and restarted it a few times and it seems reliable again now.😎

    • RE: Duet 2 WiFi wifi dead

      Hi, David, the board is not dead just the wifi module has stopped working. The wifi just reports as starting all the time although it did work for an hour or so last night. I've read all the forum posts I could find on the issue. I'm in the UK.

      Hi, yes I read that but that can't be legal, can it? I can't find any reference to a 6-month warranty for online selling rules. Given the price of the board, you'd expect it to last at least a year or two given the light use it has had. Hopefully, I'll hear from the duet team when they are back at work.

    • Duet 2 WiFi wifi dead

      The wifi on my Duet 2 WiFi was intermittent but is now dead I purchased the board directly on 15/11/2018. this is still under warranty, isn't it?

    • RE: Z probe offset always prints in the air.

      To be fair the bed is pretty shabby It was an Anet A8 and came bent from new. The bed, 1x end stop and the motors are all that's left now. I have a feeling its too out of true even for mesh compensation but I can see that working watching the z screws constantly moving.

      I use a Prusa spring steel sheet with PEI on it, all held in place with magnets and bulldog clips.

      I've got a new bed on its way in the post next week but I know how to set the probe up now thanks to yourselves. I think I'll look at different probes and try and get it as close to the nozzle as I can.

      Thanks for all your help
      All the best Andy

    • RE: Z probe offset always prints in the air.

      Yes, I was 0.2mm too close to the bed so used the baby stepping to raise the nozzle.

    • RE: Z probe offset always prints in the air.

      @phaedrux said in Z probe offset always prints in the air.:

      add an X Y move to position the probe where you want the bed probed before you call G30

      Thanks for your help I've got a lot further and am actually printing on the bed now 🙂 I don't understand how to do the X Y move to position the probe where you want the bed probed. If use the baby stepping and added 0.2mm do I need to add or subtract that from the hight I set in the config.g?

      I've got soo much to learn about RepRap.

      Thanks Andy

    • RE: Z probe offset always prints in the air.

      Thanks, I'm trying again now. So when I Send G30 S-1 to probe the bed without resetting the Z=0 position where am I taking the positive number from the top right in Machine status or from the gcode console.

      Thanks

    • Z probe offset always prints in the air.

      Hi. I've just set up my duet 2 wifi and can't get the z offset from my probe to work. The probe is triggering well I have it connected to the z probe and the power and negative is on the LCD port. It always seems to print 3mm above what is set? I have been using these instructions:

      " Checking the trigger height

      The Z probe trigger height must not vary significantly with XY position. Measure the trigger height of your Z probe at various XY positions and make sure it is consistent. To measure the trigger height:

      Make sure there is no filament stuck to the nozzle (you may want to do this test with the nozzle hot)

      Cancel any existing bed compensation by sending M561

      Send M208 S1 Z-3 to temporarily allow Z moves down to Z=-3mm. This is to ensure that you can lower the nozzle all the way to the bed in step 5.

      Command the print head to the coordinates you want to probe. To probe the centre, send G1 Z1.

      Command the print head down in small steps until the nozzle just touches the bed or just grips a sheet of paper. You may need to send M564 S0 to allow movement lower than where the firmware thinks Z=0 is. You may also wish to create a macro to lower the head by e.g. 0.02mm to get greater accuracy (G91 followed by G1 Z-0.02).

      Send G92 Z0 to define that height as Z=0

      Command the nozzle up 5mm (G1 Z5)

      Send G30 S-1 to probe the bed without resetting the Z=0 position

      Read off the Z height from the web interface. That is the trigger height.

      Repeat the previous two steps a couple of times to make sure you are getting a consistent result

      Repeat steps 4-10 for the other XY positions you want to check.

      On a delta printer, it can be quite hard to achieve a consistent trigger height. Z probes that are mounted on the effector are sensitive to any tilting of the effector, because it affects the relative heights of the Z probe and the nozzle. You can reduce this effect by mounting the probe as close to the nozzle as possible. Probing solutions that use the nozzle itself as the probe are usually not affected by effector tilt, but some types are sensitive to the XY position of the nozzle for other reasons.

      Once you are satisfied with your trigger height result (should be between 0 and 1mm, depending on your printer), open your config.g file (this can be found in your DuetWebControl), find the G31 command and enter your trigger height as a negative value in the Z parameter (ex. G31 X0 Y0 Z-.43)."
