Swing: User Guide

This User Guide covers Swing Version 1 hardware and software.

In this Guide:

  • "Click" means click the left mouse button or tap on a touch screen.
  • "Select" means find the right thing and click on it.

Safety

You are responsible for your own safety and the safety of others around you.

  • Ensure your gun is unloaded before using it with Swing - double check semi-automatics.
  • Just as at the shooting ground, never point a gun at anyone.
  • Keep batteries and other small parts way from young children.
  • Avoid explosions and fire by never recharging batteries unless they say "Rechargeable".
  • To prevent damage to your eyes, and the eyes of others, never look into a laser and never point it at anyone.
  • Use a cable protector to ensure you don't trip over trailing mains or USB cables.

Wordcraft International cannot be held responsible if you ignore these warnings.

Getting started

Please read the assembly section first if you purchased Swing as a kit.

Downloading and installing the software

  • Download the DryFire software from the support page.
  • Click on the downloaded file to start the installation.
  • When installation is complete a DryFire program icon will appear on your desktop.
  • Click on the icon to run the app which will try to connect to Swing.
  • Connect Swing to a USB port and switch on (switch to the right).
  • The app will connect to Swing.

Using Swing with the DryFire software

Swing uses the same software as the DryFire simulator.

The software detects if it is connected to Swing or to a DryFire simulator and adapts itself accordingly.

Obviously some of the functions of the software are not supported by Swing: doubles targets, shot detection and feedback for example.

Please read the DryFire software User Guide for further details.

Assembly

Skip this section if your purchased an assembled version of Swing.

Advice before starting

Swing assembly is straightforward (and enjoyable) - you should be up and running in under an hour.

Experience shows there are a number of fundamental rules when building something:

  • No one reads the manual.
  • There is no such thing as "a five minute job".
  • If it can go wrong, it will go wrong.
  • If there is a "right" way to fit something you will try all the "wrong" ways first.
  • There will always be bits left over.
  • There will never be enough bits.
  • Rules 4 and 5 are not contradictory.

So, work slowly, carefully and methodically (one step at a time) to avoid stress and screaming!

Lay all the components out in front of you and check that you have everything before starting assembly. Keep the small parts in a container (plastic margarine tubs are excellent!) so they don't roll around and get lost.

Things like screws and nuts are commonly available but let us know of any missing parts.

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. We do not support other servo motors.
  • 2x 2.6mm x 8mm pan head black Phillips self tapping servo screws
  • 4x 3mm x 5mm nylon plastic spacers for PCB
  • 2x 3mm x 4mm countersunk Pozi stainless steel machine screws for spline block
  • 6x 3mm stainless steel nuts for PCB and spline block
  • 8x 3mm x 12mm pan head black Pozi machine screws for fitting servos motors
  • 8x 3mm black nuts for fitting servo motors
  • 4x No 4 x 3/8" pan head black Pozi self tapping screws for the metal enclosure

You will also need

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

A 5.5mm nut spinner/driver is ideal (but not essential) for the 3mm nuts we use.

Grinding down the tip enables it to be used where the nuts are close to other components.

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.
  • Push the grommet into place. Note: do not use a metal object to do this - it will mark the paintwork.

Step 3

  • Put a 3mm x 5mm nylon spacer on the each 3mm stud.
  • Check you have the PCB the right way round - 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.

  • Fit the PCB (battery holder downwards) and secure with 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:

  • 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 it is inserted the correct way round- the large "+" symbol on the PCB is a clue.
  • Set 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".

    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.

  • Unplug the motors and remove the battery.

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.

  • 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.

  • 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.

Step 8

  • Stick the feet to the base after peeling off their backing.
  • Slide the base into place and make 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.

Job done!
