I have been working on a little side project to add a GCode Viewer to the DWC 2.0. I don't know if anyone would be interested in something like this but I have a little video showing it to see if there'd be interest in this.

Update
The newest versions of a new plugin for DWC 3.2 is a available here.
Been a while since I provided an update. I have been working toward getting my viewer converted to a plugin in 3.2. Here's a little sneak peek of where it is at today.
For anyone who is building and running the latest beta 3.2 you can install and test the plugin. Enjoy!

If any of you happen to be using my Gamepad Jogger plugin with the CNC build I have a new version which allows you to bind keyboard keys to commands as well.

Just finished implementing object cancelling in the 3d viewer.
https://github.com/Sindarius/DWC_GCodeViewer_Plugin/releases/tag/0.6.0
Created a new release available here
https://github.com/Duet3D/DWC-CNC/releases/tag/CNC02-(3.2.0-RC1)
Made the movement buttons on the dashboard a little larger
Added macro list to the dashboard
Included DRO and Jog plugins for feedback.
Plugins you want to try out will need to be turned on in Settings > General > Plugins Tab
@Thalios Give 0.7.6 a shot. I have reworked a chunk of the bed logic so it should pick up the axes limits from the object model now.

Also added build volume. It's a little odd for deltas but it you look top down it works well enough for now.
I've been playing around with the code a little bit while I wait for a plugin system to be put in place. Recently added the ability to change the bed size and have the release on GitHub for anyone who wants to play with this. I use it fairly often at this point.

Did some mobile tweaks in a new release that is now availabe on github.

I plan to address the ui scaling in a future release.
@oozeBot Noted. Appreciate the feedback. I'll have to look into making that an option. I think some of it comes from how you play video games. I tend to use inverted mouse when I play games so it has been more natural to me, I can see that being a problem for others.
I am resolving some alpha blending issues and trying out some different textures.
I expect to probably have another version out this evening.
Do you have your machine configured for CNC?
There should be an M453 somewhere in your config to enable CNC mode.
@MartinNYHC Yeah I don't think either of those are currently set to save. I'll look at adding them in 3.3
@MartinNYHC Some of the settings should be getting stored in the local browser, such as the extruder color settings, which setting is not saving?
@too Axes buttons on the dashboard are driven by the Object Model under Move > Axes. Extruders are in their own area in the Object Model. At some point I could look at bringing in extruders as E# axes but that would not be a focus for me at this moment.
@too the problem is that the cnc specific pages have had things like the extruder removed since they aren’t needed in cnc applications. It would likely come down to making a plugin that can bring both worlds together in a custom dashboard.
@xenon2008 do you happen to have a m551 in your config setting a password. The last person who was having problems removed it and it worked. Wonder if there is an issue with passwords.
@LB Currently the cone is simply using the current machine position coordinates from the object model to display its current position.
@Sp00kie13 at this point it is just going to show the lines. To show actual carving is a different process. Most viewers I am aware of use voxels and remove them as they are traveled through. The other thing is without endmill information it would be inaccurate. Maybe some day it will be a project I work on but probably not anytime soon.
@oozeBot That's a very clean print! Yeah I am very happy with PrusaSlicer as well. I stopped using S3D some time ago especially as I started doing more and more with multimaterial printing.
@oozeBot It's good to know that it is not an issue. With some of the newer features in PrusaSlicer I find it is really easy to mis-click and add things like M600. But it is my favorite and most used slicer
