Error: Unknown Command "" about octoprint-bedlevelvisualizer HOT 13 CLOSED

What do you get if you type just G29 or M420 V? What's your firmware?

from octoprint-bedlevelvisualizer.

The firmware is Marlin v1.1.8, have not tried with only "G29" because without the T parameter the topology does not get printed on the log output. Will try and report back.

from octoprint-bedlevelvisualizer.

That's the version I have running. Not quite sure why the command would not be recognized by the firmware. Double check you don't have any extra spaces between the 9 and T maybe?

from octoprint-bedlevelvisualizer.

Curious if G29 T1 or other T# option would be recognized?

from octoprint-bedlevelvisualizer.

Update: just realized I needed to change the "Data Collector Flag" text in setup to "Bed Height Topography:" and then after an update the graph showed up and things seem to be working as expected for me --Thanks for a cool plug-in!

Sorry to jump in but I am running the Marlin 1.1.8 firmware as well. I do get a response from the G28 and G29 T1 commands but it doesn't look like the sample. I'd also like to get the visualizer to work.

Here is an extract of what those commands return on my system.

You could also use (0,0), as that is closer to the mesh data and would reduce additional line processing, not that you'll probably notice a difference.

Sorry, have been away from the printer, will test it asap.

BTW, there is no T1 in Bilinear, only T (no number). I guess there is no T1 in UBL either.

Look at the specific options of ABL and UBL.

About to release a new version that will fix some issues reported with view bindings.

from octoprint-bedlevelvisualizer.

Version 0.0.6 just released. Give it a try and let me know how it goes. If you inadvertently got this version already during my development, you will have to reinstall manually.

from octoprint-bedlevelvisualizer.

0.0.6 is working for me now. I had to (I think) save twice for it to store the Data Collector Flag, once I had it where it persisted, it finally spit out a lovely image.

This is my Marlin 1.1.8 output, which is now parsing correctly.

Yes! It works now. The G29 T is sent correctly and after the bed leveling the graph is plotted.

A sugestion: the Data Collector Flag comes empty (you are supposed to fill in your message, I understand) but because of the help text that is in the background inside of the text box, it seems that it's already filled. It took me a while to get that I could type over that.

from octoprint-bedlevelvisualizer.

That's understandable. I'm using the placeholder attribute of the input field to try and show examples of what's supposed to go in there. Adding it as text below may make it clearer. The input field was originally a select list but there ended up being so many variations of flags to use it made more sense to make it open. Thinking of adding an initial wizard to step through the settings with instructions.

from octoprint-bedlevelvisualizer.

Would probably be best to compile a list of the most common, and autocheck for those. Then, if need be, a user can specify their exact flag. Would provide a better 'out-of-the-box' experience with really no additional overhead. Could even store the known flag once auto detected the first time, if you really wanted to limit the steps beyond discovery.
