I am trying to slice a model that is half a mm less than max width, but not successful.

What am I missing? Is there some minimum value less than maximum allowed, or something?

**Edit**: after changing the width to 220 in machine settings, slicing works. This is a dangerous thing to do, as it *could* damage the printer.
