The printer frame is rigid, and includes no aluminum extrusions (15mm or any other size). There is simply no mechanism for leveling the bed. So, the options are to add mechanical complexity simply to provide a way to get the bed level enough to print on, or add software complexity and compensate for the inevitable minor tilt present after assembly. It's easier in the long run to deal with the problem in software (assuming enough CPU cycles are available) than to add BOM parts and make a more expensive and complex machine. The software also only has to be written once, while every user would need to learn how to mechanically level the print bed. BTW: I'm currently working on a Wally, but this applies also to the GUS Simpson I'm starting on next: http://www.conceptforge.org/ -- Charles Steinkuehler ------------------------------------------------------------------------------ Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.
