This section covers some common issues that occur with the 3D printers. For any other issues, please notify staff.
If the first layer of the print is either starting too close to the bed (layer will look very thin and squished) or too high from the bed (may not be adhering to bed at all) you will want to stop the print immediately.
Often, simply restarting the print will fix the issue as it gives the printer a chance to try auto-leveling the Z-axis.
If restarting does not fix the issue, please notify staff.

Warping:

Warping occurs on prints because plastic, especially ABS, shrinks as it cools. For more details, check out this page from Simplify 3D. This is especially noticeable for larger prints. The TAZ Workhorse guide recommends that "turning on Brim in Cura will help increase the surface area of the print, improving part adhesion."
Print coming off bed during printing:
A similar issue is prints coming unstuck from the PEI surface completely during printing as seen in the photo below.
This is more common when trying to print multiple pieces or tall, narrow objects. Like warping, maintaining the PEI surface and using a brim or raft during printing may help prevent this from occurring.
For more information, read this tutorial from LulzBot on how to maximize bed adhesion.
Probably the most common cause of a bad-looking print (layer shifting, delamination, etc.) is that filament has gotten tangled.
When you're putting filament away, make sure to wrap it snugly and lock it into place with the holes on the outside of the spool.
