Error Footprint Wizard -- BGA

[macnib]

When I open the Footprint Wizard, I select row 5 BGA. Afterwards, I get a alert window with some cryptic debugging output. When I dismiss the alert window, there is no generated footprint. Also, if I modify pitch, size, columns or rows parameters the alert window appears again.

If I choose another option, like the wizard for SOIC, then Kicad appears to run normally without an error message.

Any suggested would help. I’m running on Ubuntu.

Here is a screenshot of the alert window: something about an object type error in a python script called bga_wizard.py line 87 and PadArray.py line 215.

This is a known bug, and a fix was already committed.
However, the fix was reversed, as it apparently caused some problems on KiCad Installations (I think it’s for the people who still use Python2.)

You can get to the fix by following:

Footprint Wizards are throwing Exceptions: S-DIP, SOIC, BGA

At the moment 3 of the Footprint Wizards are throwing an exception on my system immediately after startup (Before changing any parameter). Just: Start Footprint Editor. “New Footprint Using Footprint Wizard” Select one of the wizards for S-DIP, SOIC or BGA. Before making a bug report (My Linux Mint is not officially supported) It would be nice to have some confirmation, preferably also from a different OS and python2. I can’t copy / paste the text, so a screenshot will have to do. The messa…

If you compare it with other commits, you will find references to the “PadArrayGrid, self” text in about 5 or 6 different locations.

Ah, I see. I tweaked the python script like commit e622627 and the problem went away. Should work for now.

Thanks for your help. Much appreciated.
