Vertical Fine Artifacts (VFA) Test for Voron0

VORON0 GCODE for TESTING THE RESONANCES of your stepper motors

by varying print speeds from 50mm/s to 225mm/s (25mm/s increments).

This download is FREE: Just add 0€ or $0.

I don't collect email addresses: You can add a fantasy one.

Donations are always welcome, but absolutely not mandatory!

Requirements:

• Voron 0.0 or Voron0.1 (Klipper)

• print bed is properly leveled / extrusion flow is properly calibrated
• capability of moving at 225mm/s - at least 1000mm/s² acceleration needed in order to reach the speeds
• tested at "square_corner_velocity: 6.0" - you might vary here
• footprint of the print: 102mm (X and Y) - make sure you're not going out of bounds
• PRINT_START and PRINT_END are properly defined in printer.cfg

Sliced in Simplify3D:

• Two gcodes: Diagonal print-move tests your A-motor or B-motor

• Print time around 15-20min. (depending on acceleration/scv)

• PLA print at 215°C / 60°C (nozzle/bed)
• Extrusion width: 0.45mm / layer height: 0.15mm
• Extrusion flow is set to 100% in slicer (maybe vary this in firmware - check the resulting wall thickness)
• Resulting volumetric flow rate at 225mm/s is 15.2mm³/s (Cooling and/or DragonFly might be limiting at higher speeds)
• Travel moves are also at 225mm/s
