Idea: A movable „arm“ that allows going back, forth, left and right (movement in x and y direction) with a changeable „nose“.<br> Make the printers inner movements visible outside of the casing.<br><br> | Idea: A movable „arm“ that allows going back, forth, left and right (movement in x and y direction) with a changeable „nose“.<br> Make the printers inner movements visible outside of the casing.<br><br> | ||

Cutting the „arm“ pieces out of Kappafix (accessible, easy to work with, strong enaugh and flexible at the same time).<br> Gluing them together (sandwiching) for a better stability. <br><br> | |||

The upper arm needs a „Slider“ - Something that is glued to one part of the arm holding the other (movable) part of it in place. <br> It is important that the „Slider“ is not too tight nor too lose. <br> It should not be too hard to push the flexible part in and it should not have too much space to the left and right at the same time. <br><br> | |||

The „Slider“ made of papercard glued to the longer side of the upper arm.<br><br> | |||

The lower (static) arm did not move back and forth - the pressure from the wheels of the printer was too low.<br> Another single wheel had to be installed that allows the back wheels to apply more pressure on the arm.<br> The same thing has been done in the front later on.<br><br> | |||
[[File:3erWheel.jpg]]<br> | |||
How can the „joint“ of the two arms move to any x/y direction?<br> It needs wheels that are like rolling spheres.<br> This prblem has been solved with wheels from the hardware store: they contain axle bearings that allow them to circle around their own case. <br>Three of these wheels are enough for a stable platform.<br><br> | |||

Bringing the parts together with a threaded rod and nuts. <br><br> | |||

defining the reachable area by pushing the arms to their maximum position.<br><br> | |||

The PWM Schematic for controlling the speed of the DC motors.<br><br> | |||

The PWM module in its case with a knob to control the motor speed and a connector for a 9V DC power supply that works with 220V AC from a common power plug.<br><br> | |||

Bringing the parts together with a threaded rod and nutsH-Bridges for spinning each DC-motor back and forth.<br><br> | |||

The „Game Pad“ in a Kappafix case. <br><br> | |||

Everything brought together and wired up. <br><br> | |||
