About the Onyx Pillars Test Print

The Onyx Pillars Test Print can be used to diagnose printing issues on the Industrial Series. This test print is significantly more effective at diagnosing wet Onyx than the Wet Plastic Purge routine. In addition, this utility can help diagnose underextrusion as well as several other printing issues.

This routine will run for about 15 minutes and then pause to allow you to inspect the test part. Wet plastic or underextrusion 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.

Diagnose Printing Problems

The Onyx Pillars Test Print utility can be used as a diagnostic for several printing issues. See below for pictures and descriptions of potential failure modes 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 may occur between pillars or off of walls.
    Solution: Remove and discard several feet of filament from the spool. Reload the plastic and run the utility again. If the test print still shows signs of wet plastic, discard the spool and replace it.



  • Pillars with underextrusion: There are gaps in roofs or floors.
    Solution: Run the Underextrusion Troubleshooting utility. For more information, see Underextrusion Troubleshooting.

  • Pillars with pitted walls: Gaps appear on vertical walls.
    Solution: Check for tangled print material in the drybox or jams in the extruder or print head. If necessary, change the nozzle. 



  • Dimensionally inaccurate pillars: Circular pillars are wider than they are tall, or vice versa. Square pillars may incorrectly print as 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. For more information, see Adjust Belt Tension.
