Screw Tread Test

Description

This is a simple and efficient screw tread test to calibrate your slicer and printers.

It was made using ISO metrics from M2-M5 available in Fusion 360.

Recommended Print Settings

• Walls:
  • Loops: 3
  • Order: Inner/Outer or Inner/Outer/Inner
  • Generator: Classic
• Seam:
  • Position: Aligned
• Infill:
  • Density: 10%
  • Pattern: Grid or Gyroid
• Support:
  • No needed

Troubleshooting

To help in case your print does not match the metrics, check these parameters:

• Excessive material flow ratio:
  • Run flow rate, max flowrate and VFA tests from your slicer.
• Very low infill density:
  • Try increase infill density in order to get a better support to screws treads.
• Walls not enough:
  • Same case as infill, try to increase walls loop.
• Seam not aligned:
  • In a few cases, seam not set as aligned can change the screw tread resulting in failure printings.
• Very high print speed:
  • Try reduce 50% of your normal printing speed.
• Low retraction or Pressure advance inefficient:
  • Run pressure advance and retraction test from your slicer.
• Larger nozzle:
  • Try use .2 or .4 nozzles
