UM2+ print head crashing into right side panel

[mabe 0]

I recently had the unfortunate pleasure of the print head crashing into the right side wall of my printer while printing a part that was located on the far right side of the bed. I successfully replicated this problem today with a test file, and it seems that the standard machine setting of 230mm for the width of the build plate is not correct for my printer. I did not change any machine settings and am running Cura 15.04.4.

As shown in the first picture the part is well within the allowable print space.

Yet when it prints the outline the print head nearly touches the side panel on the second step already, and it would do another 4 steps at 1mm each, resulting in a crash. In the second picture you can also see the scratch from the last crash.

Did anyone else notice this? I now reduced the maximum width in the machine settings to 225mm, this fixes the problem for me at the moment. Nevertheless I find it rather strange that I have to mess with this setting at all.

Wow that's a nasty scratch

Luckily I was watching the printer as this happened, otherwise it would have looked a lot worse

The official specification of the UM2+ mentions a build volume of 223 x 223 x 205 mm.

It seems that the machine profile of Cura is a bit too optimistic...?
