How to use Bed Visualizer

I've been searching in vain for info on how to configure bed visualizer and exactly what the UI is telling me about turning the screws.

The matrix under the image seems to have the y-axis so that the near edge of the plate (y-0) is to the rear rather than the front.

Also because of my setup with a camera mounted to the left rear leveling screw (x=0, y=220). I want to adjust only the other three screws. If I click on a box in the matrix it shows 0 for that location, and I think the adjustments for the other three screws are relative to that corner, but I'm not sure.

I think you have your assumptions correct about the screw-turning UI. It's not 100% accurate as the screws can be in different places but should be enough as a starting guide.

In the bed level visualizer settings, you can rotate and flip the view. It can be helpful to put an object, like a credit card in one corner to obviously raise it up, so you know exactly what orientation the visualizer is showing.

Presumably you got it installed OK then and don't need help with that bit anymore?

Also using an elegoo Neptune 2 and trying to get bed visualizer to work. Anyone getting somewhere ?

Hello @Plaztechpirate !

Has the Neptune 2 some levelling device like BL-Touch installed?

No , I donโ€™t have the BL touch but you make a good point. I wonder autolevling needs to be installed in the firmware which is possible however it disables the ability to manually level.

Yes, some form of auto bed leveling has to be enabled in the firmware for the plugin to be able to work. This does not exclude manual mesh leveling or UBL with manual probe option, which both would also work with the plugin.

Thanks ! Iโ€™d like to avoid messing with the firmware , how would I go about doing a manual mesh leveling ? Iโ€™m new only a week or so in a having a heck of a time getting first layer down. Thanks !

If it's not enabled by default in your printer's firmware it won't be possible. That also requires firmware changes.

First of all, thanks for the nice plugin! I have an additional question though on the visualisation. Is it possible to edit the visualisation style to something like a heatmap? When I edit the data in the chart studio this is possible of course, but I haven't found it in the Octoprint environmnet. I find it way easier to interpret heatmaps instead of meshes.

It currently does not support 2D graphing like a heat map. You can adjust the camera position to look straight down and get a similar look to a heat map though.

I forgot, I had added something that is more of a streamlined version for OctoDash that doesn't have as many of the bells and whistles though that might be closer to what you are requesting. If you go to the address below in your browser it will give a flat view, replace octopi.local with ip if that's how you access OctoPrint.

The link is exactly what I was looking for, thanks!

The camera position straight down still gives perspective distortion, the flat 2D projection from the link is nicer! Thanks for the nice work, it helped me level my prusa out!

This makes total sense. I understand now thank you.

Hello Dave,, I am attempting to print doing on one ABL a day, first print of the day and then use that setting throughout the day. Is there any tips you can offer in achieving this?

Does the G-code shown in the Bed Visualizer window in octopi have to be pasted into the G-code in the prusa slicer? Or is that G-code just stand-alone in the Bed visualizer window? I have the plug-in installed, but I cannot start the application, or rather it doesn't start on it's own.

No, that gcode is used when you start the plugin with the Update button.

You can technically have them in both. If you do it in your slicer then the "saved mesh" that renders when you switch to the tab will always be from your last print job. If you were to do that I would recommend stripping it down and just adding @BEDLEVELVISUALIZER just prior to your G29 command.

I must be missing something then. The visualizer never starts up for me. It has a blue button that says update mesh with an "i" in a circle before it. I put the standard genaric Prusa settings in the G-code window, but something still must be wrong.

For my Prusa I have this in that window:

G80 N3
G81

I believe I have this:
G80
@BEDLEVELVISUALIZER
G81

My printer is a MK3s+
