New to printing so apologies if some of my terms are confusing. I have an old Taz 6 printer. I am trying to print a small square part, but the part appears to print rectangles of increasing size. My original thought was that the bed was not level but I have confirmed that the bed is level with the machine. I would like to upload an attachment of my print file and a photo showing the issue but I am not allowed to as a new user. ---

The photos will definitely help, can you post them elsewhere? The most common problem with Taz 6 machines is slight contamination of the nozzle that ruins the bed leveling compensation, leading to bad first layer adhesion. Rectangles instead of squares could easily be a loose grub screw on one of the motors causing significant backlash on movements on that axis. ---

That site requires a login to view the photos. You should be able to add them here soon, or possibly DM them to me if you can’t post them yet. ---

Your part isn’t flat on the bed. The skirt doesn’t surround the part, only the bit touching on the first layer. If you’re printing a square, you should have a square skirt. You have an elongated rectangle that indicates to me that your file doesn’t have a truly flat bottom, or it’s slightly rotated. Here’s a reproduction of a similar part to demonstrate. What it _should_ look like - first layer if it were flat on the bed: ![image](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/e/e8db590d2cfbb8095430512c700c3a6e8e37f206.jpeg) Rotated 2 degrees first layer: ![image](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/2/2e8ae7ef1d4045b5067be13e6fa21c7559aac7dc.jpeg) Second Layer (prints over the skirt - look familiar?): ![image](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/0/08cd0f77ac737d53918ea3164476ceff79265272.jpeg) Complete rendering, showing the stepped top from it not being flat: ![image](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/3/3d5adb26d2d699046c8e788925ba01439090ccb5.jpeg) ---

What can be causing that miss alignment? My part is flat on the build plate in the Cura slicer software. ![3DPrintissue_3](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/1/15e87306e287bc229248ab0337c545cf0fe20b50.jpeg) ---
