Measuring hover

Overview

To more accurately assess hover height, I use a small "staircase" that cost up by 0.5mm increments to test how hover works with tablets.

The hover testing tool

Testing process

• Overall I move "down to up"

• I begin with the pen placed on the first step which represents 0.5mm from the tablet surface.

• I then move up each step (0.5mm increment each time)

• On each step I notice

  • Whether the tablet detects the pen

  • If the tablet detects the pen, then whether there is any hover jitter. And how much hover jitter there is.

• I move up the steps until the pen is no longer detected by the tablet.

3D printing notes for tool

Printing details

• Printer: Bambu X1C

• Nozzle: Bambu Lab X1 Carbon 0.4 nozzle

• Filament: Bambu Basic PLA

• Layer height: 0.2mm

• Initial layer height: 0.2mm

• Plate: Textured PEI Plate

Accuracy

Because the layer height is 0.2mm:

• The whole number steps are very accurate

• The intermediate steps such as 1.5mm, 2.5mm are slightly thicker than they should be.

I measured the steps with a digital caliper and had these results:

• 1.0mm step = 1.04mm

• 1.5mm step = 1.63mm

• 2.0mm step = 2.04mm

• 2.5mm step = 2.63mm

• 5.0mm step = 5.04mm

• 5.5mm step = 5.65mm

• 10.0mm step = 10.04mm

• 10.5mm step = 10.64mm
