Swing: Assembly Guide

Advice before starting

• Assembly should take under an hour - but don't race - it doesn't matter if it takes a bit longer.
• Put all small parts into containers to avoid losing them - margarine tubs are excellent.
• Work slowly and carefully, one step at a time.
• Don't over tighten things. Nuts and screws should be "firmly" in place.
• Stop for a cup of tea if you feel stressed - some of the tiny nuts may have you tearing your hair out.

Tools required

• One small Phillips screwdriver - for the small screws that go into the servo motors.
• One Pozi No 1 screwdriver - for mounting the servos and for assembling the base.

  The Stanley STA062145 set includes large and small Phillips and Pozi screwdrivers

• Scissors.
• Some sticky tape.
• A 5.5mm micro nut spinner/driver is an excellent investment for fitting tiny 3mm nuts.

  The tip of the one shown below has been ground down to fit in small spaces between components.

Kit contents

You should have:

• 1x black metal enclosure: top, base and bracket
• 1x laser cable
• 1x black aluminium laser holder
• 1x bubble level
• 1x electronics Printed Circuit Board (PCB)
• 1x USB cable
• 1x black cable tie
• 1x RCR-123 16340 Li-Ion 700mAh 3.7V battery
• 2x rubber grommets
• 1x 3mm black acrylic spline block (remove protective film before use)
• 4x rubber feet
• 2x servo motors with fitting screws. We do not support other servo motors.
• 4x 3mm x 5mm nylon plastic spacers for PCB
• 4x 3mm stainless steel nuts for PCB
• 2x 3mm x 4mm countersunk Pozi stainless steel machine screws for spline block
• 8x 3mm x 12mm pan head black Pozi machine screws for fitting servos motors
• 10x 3mm black nuts for fitting spline block and servo motors
• 4x No 4 x 3/8" pan head black Pozi self tapping screws for the metal enclosure

Step 1

• Peel the backing paper from both sides of the 3mm acrylic spline block. Don't use anything harder than your finger nails to do this or you will mark the plastic.
• Secure the spline block to the horizontal servo bracket using two 3mm x 4mm countersunk Pozi stainless steel machine screws and nuts.
• Push the grommet into place in the larger hole in the bracket. Note: do not use a metal object to do this - it will mark the paintwork.

Step 2

• Use a strip of sticky tape under the hole in the top of the base to secure the bubble level in place. It will help to hold a small piece of wood (or anything flat) under the tape while pressing the level in place.
• Push the grommet into place. Note: do not use a metal object to do this - it will mark the paintwork.

Step 3

During this step you will be fitting the Printed Circuit Board (PCB) so please take care, don't rush and don't force anything into place. A cracked PCB cannot be repaired.

• Put a 3mm x 5mm nylon spacer on each 3mm upraised stud (bolt).
• Check you have the PCB the right way round with battery holder towards you (see above) - so the three LEDs go through the holes in the top and the USB socket and switch face outwards.

  Do not fit the battery at this stage.

• Don't force the PCB into place - it will fit - so wiggle it carefully down the studs checking that the three LEDs have gone through their holes.

  Now fit the four 3mm stainless steel nuts - this is where the 5.5mm nut spinner/driver comes in handy.

Centring the servo motors

Now is the time to centre the servo motors before continuing assembly.

• The servo motors may be fitted with plastic arms - which you don't need. Use a small Phillips screwdriver to remove the screws holding the arms in place. Keep the screws safe - you will need them in a few minutes.
• Ensure the on/off switch is in the "Off" position - switch towards the USB socket.
• Connect one servo motor cable to the three pin socket labelled "H" on the PCB.

  The black wire goes to "-", the red wire goes to "+" and the yellow wire goes to "S".

• Connect the other servo motor cable to the three pin socket labelled "V" on the PCB.
• Insert the battery into the battery holder - check carefully that it is inserted the correct way round- the large "+" symbol on the PCB should help.
• Check the battery direction again before setting the on/off switch to "On".
• The red LED will start flashing as soon as the motors are centred.

  The LED will flash for 5 seconds as Swing holds the motors in the central position.

• Set the on/off switch to "Off" within the 5 seconds.

  Important:

  You must switch off within the 5 second limit or Swing will enter demonstration mode and start moving the motors away from the centre. If this happens switch off and start the procedure again making sure you switch off within the 5 second delay.

• Remove the battery and unplug the motors - keep the screws safe.

Step 4

• Check you have the servo motor the correct way round - see image above - then drop the servo wire and servo down through the hole in the top.
• Secure in place with four 3mm x 10mm black pan head Pozi screws and nuts.

Step 5

• Look carefully at the image above and have the servo motor facing you.

  Check again - the two grommets should be at the same end.

• Remove the screw from the top of the servo motor - you will need it in a moment secure the bracket
• Ensure the bracket is parallel to the edges of the servo motor and metal top and with the rectangular hole away from you - as shown - then push it carefully into place. The acrylic spline block will fit onto the spline on the servo motor. Don't force it!

  Note: the male and female splines may not permit perfect parallel alignment - but don't worry about this - the software will allow for any slight misalignment.

• Before securing the bracket in place, rotate it slowly and gently from left to right until it reaches the limits of the servo motor movement. The ends should be roughly at right angles to the servo motor body.

  If things look wrong, lift the bracket off the spline and replace it a little further round. Check again.

• Secure the bracket in place with the black 2.6mm x 8mm self tapping servo screw.

Step 6

• With the bubble level towards you, check you have the second servo motor the correct way round - see image above - and push the wire and motor through the rectangular hole.
• Secure in place with four 3mm x 10mm pan head black Pozi screws and nuts.
• Pass the servo cable down through the grommet in the bracket and down through the grommet in the top of the base. You can turn the servo slowly and gently to help with this if necessary.

Step 7

Insert the laser into the laser holder.

Take care to push it in firmly then secure the cable using the miniature cable tie which you should trim short after fixing.

Now to fit the laser holder to the vertical axis servo.

• Remove the screw from the top of the servo then fit the laser holder onto the servo by pushing it carefully into place - note the direction it faces.

  Try to ensure the holder is horizontal and parallel to the edges of the servo motor - as shown.

  The male and female splines may not permit perfect parallel alignment - but don't worry about this - the software will allow for any slight misalignment.

• Before securing the laser holder in place, rotate it slowly and gently from left to right until it reaches the limits of the servo motor movement. The ends should point roughly up and down, at right angles to the servo motor body.

  If things look wrong, lift the laser holder off the spline and replace it a little further round. Check again.

• Secure the bracket in place with the black 2.6mm x 8mmself tapping servo screw.
• Pass the laser cable through the vertical hole in the front of the vertical servo bracket, down through the grommet in the bracket and down through the grommet in the top of the base. You can turn the horizontal servo slowly and gently to help with this if necessary.

Now to wire up the cables.

• Connect the cable from the horizontal servo (the one in the base) to the three pin socket labelled "H" on the PCB.

  The black wire goes to "-", the red wire goes to "+" and the yellow wire goes to "S".

• Connect the cable from the vertical servo (the one in the bracket) to the three pin socket labelled "V" on the PCB.
• Connect the laser cable to the two pin socket labelled "L" on the PCB. The black wire goes to "-" and the red wire goes to "+".
• Ensure the unit is switched "Off" - with the switch towards the USB socket then insert the battery into the battery holder - making sure it is inserted the correct way round!
• Wrap the servo cables round the horizontal servo body to make the inside as tidy as possible. Check that no wires will be trapped between the servo body and the base when you fit it.

Step 8

• Stick the feet to the base after peeling off their backing.
• Check that no wires will be trapped between the servo body and the base then slide the base into place making sure you have access to the USB port and on/off switch.
• Secure the base to the top using 4x No 4 x 3/8" black pan head Pozi self tapping screws.
