Axis Position Logger

absolutely perfect now, thank you very much, I'm looking forward to an assessment of my input from today later?

Are you looking for a way to trigger the position logger from gcode. (eg by setting a digital output using M62..M65)?

thank you very much, I've been trying out how to handle my records for a long time today and finally I can say that everything is fine the way it is now

Weren't you looking for a way to take a snapshot of an area on the screen on a log event before you edited your post?
Could be done probably.

yes I did, it was something like this:
for reverse engineering, move to various interesting practical positions with cam-align and then log the position with a button, save it together with a suitably numbered snapshot, store everything in the same folder, E.g.
after later importing a set of points into CAD, it is easier to process further using the Images illustration, for mechanics, 3D printing or electronics layout

maybe we can use Cam-align with a Manual Log button and a matching trigger output
cleverly triggered Axis Position Logger 
Spectacle screen grabber (smartly triggerable with shortcut and with area selected)
both can remain in the background after configuration so that no more tabs have to be switched 

I'm currently preparing a small presentation, I'll post it here immediately
 

    
 

Spectacle is an excellent screen grabber tool, I think, and apparently remains active in the background until the system reboots. Is there any clever way we could use a Snapshot button in Cam-align to do an F4 shortcut, Aciera, please?

I'm a bit short on time today. Have a look at this, needs a bit of work still. It redefines the topleft button in the cam_align tab to call a subroutine that pulses 'motion.digital-out-00' which is connected to 'motion.digital-in-00' which in turn can be set up as a Log trigger in the Position Logger.

 

 

to test:
Copy the 3 folders from the zip to your configfolder

also you need to modify your ini:
This changes the behavior of the top left button in the cam_align tab
Also you need to add these to the [RS274NGC] section
And add this to the [HAL] section:

Executing MDI command: 'M129' should start a logger window.
- click on 'Define Area' and check 'Enable' in the 'Screen Shot' section
- setup Log Trigger for 'motion.digital-in-0'

Clicking on the topleft button in the cam_align tab should now save a screen shot to a new folder 'emclog_images' to the current project path (usually the folder 'nc_files').

Give it a go and tell me what you think.

Thank you, that looks really exciting, how can you just shake it all out of your sleeve like that, David, my goodness? I have to try this out carefully!

Well, even with shameless copy/pasting from the internet it still takes a fair bit of work.

The version above had a bug when saving the images, should work better now:

Might have to move this to my github account.

[EDIT]

Some polishing:
- File open/save now with options (ngc/txt)
- Image file index auto increments now by default
- SpinBox value for Image file index now updates to value of next index
- autosave/-load some more settings

[EDIT2]
- fix crash when trying to save image on package installations

[EDIT3]
- fix Log Comment section reappearing on startup
