Cura 4.0 UM2GO build volume bug

[JimT 8]

I posted this in the printer forum, but no one there responded. The Ultimaker 2 Go is advertised as having a build volume of 120 x 120 x 115 mm, but I am frequently unable to print objects smaller than that. I get a message from Cura 4.0.0 saying that it is unable to slice because the model doesn't fit in the Go's build volume. I have Support and Adhesion turned off, so they shouldn't affect the build volume. I've attached an example STL file that won't print on my Go, even though it is significantly smaller than the Go's advertised build volume. I've also attached a screen print showing the error message that Cura issues. Is the Go's build volume smaller than advertised? Or is there a bug in Cura?

I think the problem are the clamps on the glass. I loaded your object and reduced it just about 1mm and it fits. So yes you have 120 x 120, but not at the same time 🙂

If you look at the footprint of the object, it does not come close to the clamps, so that's not the problem.

It is the problem, because Cura don't just check the footprint, you see it on the shadow, it uses the whole object to check if it fits or not. Makes no sense, but it is so.

If that's the case, then it is a bug in Cura, which should be fixed.
