Can't seem to add Support Blocker - Cura 4.9.1

[pjjoh1 0]

I might be going a little crazy, but I can't seem to add a support blocker.  The aim is to set certain sections of my print to 100% infill, whilst have others at a standard infill.

After I select the model, then press Support Blocker on the Left hand pane and press the image again, I don't get the box appear.  Am I doing something wrong?

 

Here's a screen recording of what I did: 

 

 

Am I going mad?

You're not doing something wrong! I also don't quite now what is going wrong for you.

 

Could I ask you to report this issue on our issue tracker? You can find it here: https://github.com/ultimaker/cura/issues/

I should have done this earlier, but resetting Cura by deleting everything in the config folder and starting again fixed this problem.

 

1. Help Menu -> Show Configuration Folder

2. Quit Cura

3. Delete everything in folder

4. Restart Cura

Well it fixed it for that session.  After a restart, it failed again.  Looks like it might be related to the issue where the Model can't be selected by clicking on it that others have reported.
When the issue is there, you can't just click on the model, it won't become selected.

When the issue is not there, you can click on the model, it will select, and then you can click on the other things like the support blocker and it will work.

ok, progress.  Issue is really around not being able to select the model.  When Cura is on my Macbook's primary screen, everything works.  When Cura is on my secondary screen, I can't select the model by clicking on it, and hence can't place the blocker.

Turning scripts off worked for me.

Installed cura from scratch, no plugins whatsoever and still unable to add support blocker on a newly created project. Anything wrong?

as a last resort I added plugins, added a cube for calibrations and set that as support blocker. 'Solved'

If it doesn't work, then... yeah, sounds like something's wrong. My Cura installation is stuffed to the gills with plugins and I can still create a support blocker fine. Please don't take offence if I post the "for dummies" step by step version since even the best of us (or me) are dummies sometimes:

1. Make sure you're in Prepare mode:
   
2. Click your model to select it:
   
3. Click the support blocker button on the toolbar on the left: 
4. Click on roughly the right part of your model where you want it, you're probably going to want to move and resize it anyways:
   
5. Click on the support blocker so that only it and not the model is selected:
   
6. Use the move and scale tools to get your support blocker in the right place:
   
   We don't want it any bigger than it needs to be because then it might block supports where you want them, though on a model like this it should be alright.
7. Switch to Preview mode, slice and enjoy (hopefully)!
