Hi Alan,
The size of the hole is hard to measure, sorry.
If you have not a filament wire in that hole, layer of the paraffin
will be thick, and that is bad. Dots are overlapping partially, it
make to much paraffin there. You have to have that filament wire.
A hundred dots make 1 inch line.
A "drawing speed" is 200 dots / minute, approximately. You can change
and adjust it, in the file CNFG.TXT, by changing the time loops, and
select what is best for you.
For a good looking line, tapping looks necessary.
Distance from the PCB surface to the tip point, when the pen is up,
approximately 1mm. I am not sure if you ask for that distance?
