**Hello Lulzbot Community,** I recently received my Lulzbot Taz 5 last week and have been frustrated with the calibration. Today I have printed a couple calibration cubes that I got here… [http://www.thingiverse.com/thing:271736](http://www.thingiverse.com/thing:271736) I will post the two most recent prints, I used Lulzbots Cura with the profile set to medium PLA (any adjustments to the profile are stated below). I printed both at 205 degrees hex head and 60 heated bed (per lulzbots recommended temps). Filiment dia was to 2.9 based off caliper measurements. [http://i58.tinypic.com/11lpj04.jpg](http://i58.tinypic.com/11lpj04.jpg) [http://i60.tinypic.com/t645yr.jpg](http://i60.tinypic.com/t645yr.jpg) The left cube was at 99.25% flow while the first one was at 100% flow. **My Issues:** They both measure the same… roughly 20.1mm x 20.4mm x 14.95mm. First: why are the cubes dwarfs?! They are squished down… if you compare to the thingiverse cubes. Something wrong with my Z-axis? It should be 20mm high! ☹ Second: looks like we have some waves going on… I read that may either be from over extrusion or x/y-bend slop? I check the belts and they seem firm and taught. Any help would greatly be appreciated. I wanted to start printing parts but they were not to the correct dimensions. Thank you! --- _[View the full topic](https://forum.lulzbot.com/t/new-user-calibration-cube-issues/1521)._
