Ultimaker's true maximum building volume

Recommended Posts

The advertised volume is 210x210x205mm. However each of these dimensions is wider than the blue bounding box shown in Cura (13.03). On the other hand if one uses the "to max" button in Cura one gets 178,2x178,2mm which is notably smaller than that same blue bounding box. Only the height of 200mm is a match.

Perhaps if one moved the head using the Ulticontroller one would get yet another set of values.

In any case, I need a part as big as the UM can print, how big is that in reality (with default hardware) ?

Cura accounts for the skirt/brim or raft. Disabling those gives more build volume. Cura also defaults to a slightly smaller print area of 205x205x200mm, to account for possible difference in builds where endstops have slightly moved.

You can change the preferences to 210x210mm and disable the skirt in the expert settings (skirt lines to 0) this gives more print area.

Every machine is different so you'll have to home, then us pronterface or cura to move the head to position x=205 and then move 1mm at a time until it triggers the limit switch. You can go to the value *before* it hit the limit switch. Repeat this test for Y and Z axis.

If you hit the limit switch during printing it will mess up your print. If you try to go over the limit switch by .1mm you probably won't notice anything, but a whole mm over will mess up your print.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
