Edit Layers
When making braille signage, you need two identical
Layers
with the braille pattern, one for
milling holes and one for inserting braille spheres.
These
Layers
may consist of circles or points.
Layer: Braille Drilling (MultiCUT/MultiCUT-HP)
Velocity Z
Velocity Z is material dependent and may require experimentation.
The value shown in the illustration is suitable for (and has been tested with) 3mm Dibond.
Z-axis depth
Z-axis depth is determined by the material thickness and hole depth.
It can be calculated as: Z-axis depth = hole depth – material thickness.
According to the Raster Braille manual the hole depth should be 1,07mm (0,042”).
You may find that the holes being milled are either too shallow or too deep. If so, use this
parameter to adjust to a suitable setting.
You will see this if the spheres sit too low or too high.
The standard specifies a sphere height of 0,6mm (0,023”).
Example using 3mm Dibond: 1,07mm – 3mm = -1,93mm
