CNC: Tool Offsets, Coordinate Systems, Confusion

Yup you can find it here: https://github.com/lockryan/DuetWebControl

I suggested to chrishamm long ago that DWC needs an option to display both machine and work coordinates. But I am guessing that your fork goes beyond that.

Thanks everyone - I've managed to run a few simple test cuts after using my "cheapishaw" probe, and I'll try a more complex part tomorrow. So far it's looking very promising.

@vwegert Good luck!
@Ryan-Lock ditto!
Workspace switching and handling sounds great, having been batch-making PCB's via a web interface without it i can comfortably call it a killer feature I got heartily sick of having to switch to the console to swap co-ordinate systems. Adding macro buttons helped, but made the UI look diseased.

[Ryan Lock]

@EasyTarget Yeah we have found for users doing production manufacturing they require easy use of all work coordinates. After the release of this version, the next thing i am going to add is the ability to apply custom names to the systems, instead of just numbers.

This sounds very intriguing. Are there some screenshots anywhere of it up and running on a CNC?

[Ryan Lock]

@Danal I haven't got any to hand right now, but will make some

Take a quick look at the work coordinate selector built into ChiliPeppr.:

http://chilipeppr.com/tinyg

When not connected to a controller board, it WILL show the coordinate selector, it will not show the axis DROs for work and machine.

I like the coordinate selector. Play with the + and - buttons, click on a level and see it highlight, etc. Source for it is here: http://github.com/chilipeppr/widget-wcs Javascript/HTML5, so easy to grab chunks and reuse them in browser based apps.

Actually, I like the DRO style display as well, but I will need to be connected to a board to show you a screen shot.

Thanks for the info, their system is pretty nice! I like their graphics to see which layer you are on.

Mine is simply just a drop down list which allows you to select which one. On one of the settings page i am hoping to add a panel where you can see the work zero for each system in machine coordinates, edit them, and give each system a custom name, which will then show in the drop down instead of the number.

Nice screenshot.

One suggestion: Make Work v Machine visually different. Larger/smaller, different colors, etc. It is fairly standard to make Work larger/bolder/brighter.

[Ryan Lock]

Thanks for the suggestion i will see what i can do.

IF we are making suggestions here; this is mine. I do a lot of manual jogging when making PCB's etc. The ESP3D derived jog control panel on my esp32 based controllers webUI is excellent; heartily recommended, very intuitive to use.

The blue buttons at the right are Macros, the little buttons beside the machine position are for zeroing individual or all axes. Per-axis homing is also supported and has proved handy on occasions.
Not shown is how each concentric ring is a different amount; and a clear animation hilights exactly what you are about to click on, and what it does.

This is slightly out of date; the latest version shows machine as well as workspace position, I like having the macro editor right there in the panel too.
I just switched to using this after using the jog controls in LaserWeb a lot; those are similar layout to the Duet WebUI, easier to mis-click, I do have some foundation for preferring the bullseye approach.

[Ryan Lock]

@EasyTarget Thanks for the suggestions, i will take them all on board. I have had a few other people prefer the bullseye approach to jogging as well. I have stuck with the current Duet Web Control jogging in our control to speed up production. But definitely something for the future. I have also got a lot of request for keyboard jogging.

Listen to those requests! It's something on my wish-list too.

[Ryan Lock]

@EasyTarget Haha i will figure it out

When Adrian Bowyer was developing the first firmware for the Duet, I tried to get him to put a bullseye similar to Pronterface's into RepRapFirmware, to make it easier for people transitioning from Pronterface! Never happened...
