I will add pictures to this post when I get home and can take some, but I noticed last night that the 4 corner feet of the Y-axis don’t touch the desk that the printer sits on. The main housing appears to be square (I saw the bulletin about a production run where the frame could go out of square during shipping). Anyway, in cleaning up some filament particles from the desk I noticed the front right corner pad wasn’t touching the desk (it was about 2mm high). In looking at the others I then noticed that none of them are touching the desk. Essentially the entire Y-Axis assembly is suspended slightly.
Is this normal or should the 4 corners be touching the desk as well?
Edit 7/12/2016 - added pictures of the front two feet. I believe the gaps are about the same and it is the camera angle making one look larger than the other. Hard for me to get to them but it appears the rear feet are the same. If it is normal then that’s fine but I’m thinking I’ll probably print some longer feet, or some shims, if even just for peace of mind. I did contact Lulzbot support and their initial response referenced me to the two TAZ 6 service bulletins about the frame being out of square after shipping and the threaded inserts being pulled out. My printer was produced after the specified serial numbers and doesn’t exhibit either issue. In response I put together a quick & dirty diagram of the issue and am waiting to hear back from them.
