Sorry Kunda, I can't remember exactly what I did any more - but I seem to remember that I didn't really need the debugger. Anyways I finished the project, so I suppose this thread can be closed.
Thanks to everyone who tried to help.

I rebuilt the whole project and I thought I'd fixed it, but now the following error occurs intermittently when I call a2p_solver.solveConstraints():

I figured out it happens at 92.0º...

Thanks kbwbe, I used that constraint a few times but thought there was something wrong as it moved things around - I didn't realise I had to fudge it. Anyways, I've got everything constrained now but when I run the macro simulation it goes well for a while then all of a sudden the slide shaft moves ...

Well All, after many attempts I finally got everything placed and all but one constraints fixed. The last constraint I'm having problems with is a pin within a slot. I've tried several types of constraint, but none work. So now I'm wondering if it's possible to do what I want? What constraints would...

I can't see a package installer for pdb++... I wonder if I downloaded the correct file?

Awesome Kunda1, I've downloaded the zip file but GitHub doesn't properly detail how to install it - All it says is: Installation Since pdb++ is not a valid package name the package is named pdbpp: $ pip install pdbpp pdb++ is also available via conda: $ conda install -c conda-forge pdbpp Alternative...

Hey kbwbe, that worked (though I still have errors) - But why are the names different? And how can I make them the same when creating new objects??

Hey Kunda1, I'm looking for the pdbpp code debugger but all I can find is the pdb module. Could you please supply a link to where we can download the pdbpp module? Mod Edit: This thread was split from another thread because it was off-topic. The context of this thread started from the following yout...

Thanks Vox, great post you sent us to - I'll be checking out 'pdbpp'.

The program I have trouble with only has 35 lines and I know exactly where the problem is - I just don't know why.
