I really want to learn how I can get better and photos sharper.
That will come from practice, trying different settings, speeds, etc.
My first two design of the day are size 10cm by 7 cm.
My picture was also laser reproduced at 100mm width.
Can you explain the Y scan distance????
The Y axis ‘stepover’ is the vertical distance between horizontal scans.
When focussed, I can achieve a laser spot size smaller than 0.1mm so a 0.2mm Y axis stepover will show the horizontal lines in the finished work. This can be avoided by either de-focussing the beam slightly or reducing the stepover to 0.1mm. In practice and to reduce the overall processing time, a slight de-focus together with 0.15mm stepover seems to produce the best results for my setup.
Basically, start at a Y axis stepover of 0.2mm then if you can see the horizontal lines reduce the stepover, in small increments, until the lines are not easily visable.
Diode lasers (because of their method of manufacture) do not produce a perfectly round spot so rotating the whole laser body until the longest axis of the dot is at 45 deg. to the horizontal may produce better overall results for both the X and Y planes.
A diode laser of 450nm wavelength may not react with the clear coloured glaze on ceramic tiles. You need to test this.
