Print a 215 x 215 x 200 mm cube on the UM3 as advertized in the specs (real build volume)

[ssichab 0]

Hi anyone,

If I print (with only one extruder) from Cura, how can I get this 215 x 215 x 200 mm cube advertised on the UM3 specs ?

Even with any adhesion methods turned off, the cube only turns yellow until it's scaled down to 83%

May sound stupido but how could I print according to the largest build envelop ?

Did you try to move the object while scaling down?

I know the advertised size is not really what you can achieve in Cura but it should be way closer to 200x200x200

Because of things like extruder prime locations, and the extruder switch bay protruding into the build volume, there are areas along the depth of the machine where you can't reach the full width and areas along the width of the machine where you can't reach the full height. These areas are shown as grey shadows on the buildplate.

If you turn off build plate adhesion options, it should be possible to print a block of - say - 10 wide and ~20.5 cm deep centered in the buildplate. A full block on the buildplate is just an unrealistic "worst case scenario".

Can't be done. Period.

No Ultimaker printer yet has been able to print an object the size of the advertised build volume. Simply stated, they mislead about it in their sales literature, to be kind.

And don't forget about the horrid build-plate clips that also preclude use of parts of the area.

...so... we can print 215x215x200 (or 300), just not all at the same time, or all of the time? ie.some shapes can reach 215 wide in some areas of the build plate... same for other dimensions?

Correct regarding X and Y directions. I haven't tested the Z-height - that would vary a bit based on the print-head and nozzle used.

Set the brim to 0mm. Cut off corners.

I could get it to slice 207x206x200 at max.

The bright printable area in Cura is only slightly larger than the 207x206 mass. 208x207 won't slice though.

have you set "travel avoid distance" to zero as well? This is default set to 3mm.

Cool. Can go up to 212x213 now.

This is one of the major reasons why I'll be selling my Ultimaker 2 - larger build volume.

BTW, your actual Ultimaker may or may not work with those last few end-of-travel millimeters at the right.

Depending on the exact location and bend in the Home limit switches, you may lose a millimeter or two when you try to print - mine can actually print a 220mm wide object between the clips.
