Subject: Prevent infinite loop
X-Git-Tag: lulzbot-18.01~1
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;ds=sidebyside;h=94821569294a65e9101897617a1e2a6be02caab7;p=cura.git

Prevent infinite loop

Changing width/height previously resulted in "RuntimeError: maximum recursion depth exceeded"s which gave very strange behavior.
