• Square glass plate with 200 mm wide and about 3 mm thick (you can also use a standard square mirror
that can be purchased from IKEA – model SöRLI)
• Square plan, 200 mm wide and 10 mm thick, made of wood (MDF, plywood …) or plastic (forex, expanded
polyurethane…) with no humps, bumps or other deformations.
• Double-sided tape.
T
he first step is to use the K8200 to print the bracket for the mandrel whose file can be freely downloaded
from the following link
(http://www.thingiverse.com/thing:225465)
. The bracket, fitted out with a collar
with a 20 mm hole, allows you to attach to the structure any electric-mandrel with cylindrical collar having
the same diameter.
To secure other types of electric mandrels you need to change the bracket collar, creating the same kind of
To secure other types of electric mandrels you need to change the bracket collar, creating the same kind of
thread present on the power tool (by editing the skp file).

To use the K8200 modified as CNC milling machine is necessary that the work plane is perfectly coplanar with
the tool in order to obtain a uniform etching of the whole printed circuit board.
For this purpose it is necessary to carry out a particularly precise adjustment as described later. For this
For this purpose it is necessary to carry out a particularly precise adjustment as described later. For this
adjustment can also be used a comparator to be mounted on the same bracket of the power tool via an
adapter printable with the same K8200 and that, of course, will be made before you make any mechanical
changes described below.
We recommend, therefore, to print one or both plastic pieces before proceeding with the printer changes.
The electric mandrel is separately powered and requires no electrical connection to the machine. The switching
We recommend, therefore, to print one or both plastic pieces before proceeding with the printer changes.
The electric mandrel is separately powered and requires no electrical connection to the machine. The switching
on and off of the tool must be done manually via the power switch supplied.
To transform the printer in a CNC milling machine first of all is necessary to have the equipment, small
hardware and various elements (visible in the picture), of which we give the full list.
