About the Onyx Pillars Test Print
The Onyx Pillars Test Print can be used to diagnose printing issues on your printer. This test print is significantly more effective at diagnosing wet Onyx than the Wet Plastic Purge routine. In addition, the Onyx Pillars Test Print can help diagnose under-extrusion or several other printing issues.
The Onyx Pillars Test Routine will run for about 15 minutes and then will pause to allow you to inspect it. Wet plastic or under extrusion issues may be visible at this time. As with any paused print, after inspecting the part, you will have the option to stop the print or to resume it. Resuming the print will allow it to run for another hour or so and may provide more definitive results as to the quality of your plastic and prints.

Using the Test Print as a Diagnostic Tool
See below for pictures and descriptions of potential failure modes for this part and what they mean. If you experience a failure mode that is not shown here, please Contact Support for additional assistance.
- Good Test Pillars: Walls and floors are well-formed, lacking gaps or stringing. Plastic is uniformly distributed and all shapes are dimensionally accurate.
- Pillars with Wet Plastic: Stringing between pillars or off of walls.
Solution: Pull several feet of filament off of the spool and discard it. Reload the plastic and run the Onyx Pillars Test Print again. If the test print still shows signs of wet plastic, discard the spool and try a new one.
- Pillars with Under-Extrusion: Gaps in walls or floors.
Solution: Change the nozzle and check for any jams in the drybox, extruder, or print head.
- Pillars with Dimensional Inaccuracy: Circles are wider than tall, or vice versa. Square pillars look like rectangles. Plastic is not evenly distributed.
Solution: Check the belt tension and the bearings in your pulleys. Dimensional inaccuracy on this print can be a sign that the motion system on your printer needs to be calibrated.
