A member having looked at one of our images suggested that a Bahtinov mask to improve focus would be a good idea. We do need all the help we can get in the focus department
We looked up on-line details and there appeared to be discussion about the sharpness of the edge of the mask influencing its effectiveness. We couldn't find any suitable dxf files on line, so made up our own based on someones calculations and made two examples. One is 3D printed and the other is CNC routed from 0.8mm aircraft birch ply mounted on a 3D printed holder.
Questions-
Are the edges sharp enough?
Which is the better version?
Does it need to be matt black? The 3D printed PLA is definitely glossy and presently the aircraft ply is unpainted but we did see some on-line in unpainted wood.
Thanks for your assistance.
