Padelshooter: Quick Start Guide

1. Power Connection

Steps:
1. Connect the battery to the Padelshooter using the cable.
2. Turn the machine’s switch to DC mode.
Note:
- Always use a fully charged battery for consistent performance.

2. Standard Positioning (2 Players)

Location:
- Place the machine at the back of the court, close to the backglass.
- Position it in the horizontal middle of the court (aligned with the center line).
Alignment:
- Ensure the machine points toward the middle line of the court.
- Calibrate Method:
  1. Select Fixed training. Set Left and Right sides, Width = 50
    
    OR
  2. Use the Middle button (Settings screen) to check if the ball bounces near the center line.

3. Alternative Positions (1 Player)

Corner Placement:
- Place the machine in the corner of the court.
- Angle it toward the opposite skew corner (diagonal targeting).
Purpose:
- Trains corner shots with realistic rebounds:
  - Balls may bounce off the backglass first or sideglass first.
- Simulates real-match scenarios where players often defend from corners.
Full Left or Right side positioning:
- Place the machine in the middle of the court (the standard position for 2 players, described earlier)
- In Settings screen, press Left or Right positioning button for the side you want to train
- Angle it so that the ball bounces on the middle line
- Now the Padelshooter is using the whole Left or Right side (also the side walls)

4. Key Adjustments for Different Setups

Scenario	Machine Position	Training Benefit
Standard (2 players)	Center-back	Balanced drills for doubles
Corner (1 player)	Skewed diagonal	Realistic defensive practice
Side-focused drills	Off-center (e.g., 70% Left)	Targeted footwork training

5. Pro Tips for Optimal Use

For Corner Training:
- Use Random or Hor Movement mode with Width = 70-100 for variability.
- Combine with Spin to simulate unpredictable rebounds.
For Accuracy Testing:
- Start with Fixed training + Width = 0 to verify machine alignment.
Safety:
- Ensure the machine is stable and won’t move during operation.

Start Playing

1. Getting Started

Begin with “Start Here” Screen:
- Use the preloaded trainings to familiarize yourself with basic settings.
- Each training displays its last-used settings – adjust as needed.

2. Selecting Your Training

Choose a Training:
- Press any training button (e.g., Fixed, Random, Volley-Bandeja).
- The app shows the latest settings for that training. Modify if desired.

3. Setting Court Position

Select Side/Area:
- Start Here Screen: Choose Left, Right, or Both sides.
- Trainings Screen: Define precise zones with Left% and Right% (e.g., 30-70% for central drills).

4. Adjusting Ball Height

Variable Height Trainings (e.g., Random, Vert Movement):
- Net: Lowest ball position (e.g., volley height).
- Height: Highest ball position (e.g., lob height).
Fixed Height Trainings:
- Set Net = 0 and use Height to control trajectory.
Combination Drills (e.g., Volley-Bandeja, Cross):
- Net: Height of the low ball (volley).
- Height: Height of the high ball (bandeja).

5. Configuring Horizontal Placement

Width Setting:
- Width = 0: All shots at a fixed position (center or selected side).
- Width > 0: Shots vary within the selected side/zone (higher = wider range).

6. Key Interactions Between Settings

Parameter	Effect	Adjustment Tip
Speed	Higher = deeper balls	Reduce Height for same depth at higher speeds.
Spin	Topspin (+) = shorter; Backspin (–) = deeper	Combine with Speed for precision.
Height	Higher = loftier trajectory	Lower for faster, flatter shots.

7. Pro Tips for Best Results

For consistency: Start with Width = 0 to master footwork before adding variability.
For depth control:
- High speed + low height = deep, flat shots.
- Low speed + high height = short, lob-like shots.
For spin: Use backspin (–) for defensive deep balls, topspin (+) for aggressive angles.

Example Workflow

Select Volley-Bandeja training.
Set Net = 30 (volley height), Height = 70 (bandeja height).
Choose Width = 50 for moderate randomness.
Adjust Speed = 25 and Spin = –10 for deep, slice-heavy bandejas.
Press Play and focus on net transitions after each bandeja.

Troubleshooting Quick Checks

⚠ Ball too short/long? → Adjust Speed + Height inversely.
⚠ Inconsistent placement? → Verify Width and Side settings.
⚠ Spin not effective? → Use more extreme values (±30-50).

3. Special Notes

Delay: Only applies after bandeja (time to return to net)
Width=0: Both shots land at identical horizontal positions
Side selection: Required before starting
Go to net: Go back to net after bandeja to hit a good volley (don’t be lazy 🙂 )

Technical Execution

Ball Sequence:

Volley (Net height, random/fixed width) → Immediate return
Bandeja (High, random/fixed width) → Delay → Repeat

Example Configuration:

Width=50, Delay=40:
- Volley and bandeja randomize across 50% of selected side
- 0.8 sec pause after bandeja

Training Applications

For Singles/Doubles:

Practice net approaches after defensive shots
Improve recovery speed from deep positions

Progression:

Beginner: Width=30, Delay=70 (more time to react)
Intermediate: Add spin variations, Width=70, Delay=30, Freq=60
Advanced: Width=100, Delay=20 (full court + quick recovery), Freq=80

Pro Tips

• Start with lower Width (30-50) to focus on footwork
• Use higher Delay initially (60+) to master transitions
• Film your net return to optimize movement efficiency

Padelshooter BLE Connection Issues: Verified Fixes

For Low-Energy (BLE) connections only, BLE is the newer bluetooth version. Note: We found that iPhone bluetooth (the Apple bluetooth version) is lower distance range than many Android phones. If you can choose both mobiles for controlling the Padelshooter, choose an Android phone!

1. Essential Checks

BLE Compatibility

Your device must support Bluetooth 4.0+ (all modern phones do).

Permissions (Critical for BLE)

iPhone: Enable Local Network in Settings → Padelshooter
Android: Allow Location + Nearby Devices permissions

Distance Limitations

See if a distance of 3 meters (10 ft) works to make a connection
iPhones sometimes have problems with 10+ meters, especially when phone is in a pocket

2. Device-Specific Solutions

For iPhones:

Issue: Weak BLE signal stability
Fix:
1. Place phone within arm’s reach of Padelshooter
2. Disable WiFi temporarily (2.4GHz interference)
3. Toggle Airplane mode on/off to reset radios

For Samsung/Android:

Issue: BLE stack glitches
Explanation: Samsung made their own phone version of bluetooth which has some “energy savings”. The result is that many Samsung phones don’t scan for devices they don’t know. To make the Padelshooter a “known device”, use an app like nRF Connect to scan for devices.
Proven Fix:
1. Install nRF Connect (BLE debug app)
2. Scan → Select “Padelshooter” → Connect once
3. Now open Padelshooter app – should connect instantly

3. Connection Recovery

Force-Close App → Reopen
Restart Phone Bluetooth:

Android: Settings → Bluetooth → Toggle off/on
iPhone: Control Center → Tap Bluetooth icon twice
Clear BLE Cache (Android Only):
Settings → Apps → Show system → Bluetooth → Storage → Clear cache

Padelshooter Ball Block: Causes & Fixes

1. Wet Balls

Problem: Moisture reduces wheel grip.
Solution:
- Always use completely dry balls.
- Store balls in a dry container between sessions.

2. Slippery Shooting Wheels

Check: Feel wheel surface for (blue) court material buildup.
Quick Fix:
- Lightly roughen wheels with fine-grit sandpaper or a file.
- Avoid excessive filing – stop once grip improves.
Permanent Fix:
- Contact De Racketclub for professional wheel resurfacing.

3. Obstructing Ball

Problem: A single ball jammed near wheels blocks the system.
Solution:
1. Power off the machine.
2. Remove ALL balls from the internal tray.
3. Visually inspect wheel area with a flashlight.
4. Reinsert balls one by one to test.

Prevention Tips

✔ Regular Maintenance: Clean wheels weekly with a dry cloth.
✔ Ball Quality: Replace worn/compressed balls (they slip more easily).
✔ Storage: Keep machine covered when not in use to avoid moisture buildup.

When to Seek Help

→ If blocks persist after trying all fixes, contact De Racketclub for a wheel inspection.

Padelshooter Troubleshooting Guide

1. Feeder Running Non-Stop

Cause:
- Dirty/felt-covered sensor (below feeding hole)
- Loose sensor connector (from ball impact)
Solution:
1. Power off machine
2. Vacuum sensor area thoroughly
3. Check connector on main board
4. Test with 1-2 balls before full reload

2. Incorrect Ball Speed

Check First:
- Verify sport mode (Padel/Tennis)
- Confirm manual speed setting (don’t rely on defaults)
Advanced Fix:
- Use 2025 speed calibration document
- For extreme low speeds:
  - Precede with slower transition shots
  - Increase pause time (lower Frequency)

3. Limited Shot Coverage

Quick Checks:
- Both “Left” and “Right” enabled?
- Width set to 100?
- Correct Side% ranges (0-100%)?
Pro Tip: Test with Width=0 first to verify center alignment

4. Netshots Occurring

Scenario	Solution
Fixed-height trainings	Increase “Height” value
Random-height trainings	Raise “Net” minimum height
Programmed sequences	Add safety margin (+10% height)

5. Height Setting Ignored

Critical Check:
- “Net” must be ≤ “Height”
- Set “Net”=0 for absolute control
Note: Machine prioritizes “Net” as minimum height

6. Speed Transition Issues (Programs)

For better low-speed shots after highspeed:

Insert transition shot at intermediate speed
- Example: 100 → 60 → 30 instead of 100 → 30
Increase pause time (lower Frequency)
Use more extreme values (very low speeds may need 5-10)

7. Volley-Bandeja Optimization

Step-by-Step Setup:

First configure perfect bandeja:
- Set ideal speed (15-30)
- Adjust height (60-90)
Then add volleys:
- Start with Height=25-40
- Fine-tune while maintaining bandeja quality
Adjust Delays:
- Longer pauses help wheel speed changes

Prevention Tips

Weekly Maintenance:
- Clean sensors with compressed air
- Verify all connectors
Ball Management:
- Use only dry, regulation balls
- Replace worn balls annually
Software:
- Regularly update app
- Recalibrate after firmware updates

When to Contact Support

→ If issues persist after all checks
→ For hardware repairs (wheel resurfacing, sensor replacement)
→ Speed calibration beyond manual adjustment

The machine is shooting too fast for all trainings

During the development of the Padelshooter, there were some small hardware changes. One of these changes was that newer models shoot with a higher speeds than earlier versions. Because of this, in the app you could set a value for the Maximum Speed of the machine (1-250). The settings in the app for the speed are all percentages from 0-100 and is a % of this Maximum Speed. So, if the speed for all trainings is too fast, you could change this Maximum Speed (for example from 90 to 60). Then a speed in a training of 100% means it is the highest possible speed from "Max Speed" 60 (and not 90 anymore). This could also be used when there is wind on an outside court. When the wind is in front of the machine, the balls are shot slower because of the wind and these land not as deep as normally. Then, changing the speed (for example from 90 to 120) will help to let bounce the balls at the same location as normally (without wind).

Balls were shot too fast behind each other

For the Trainings screen and the Programs screen, the Frequency setting could be changed lower or higher for all balls. For example when you play "Random" balls and you have not enough time to hit the next ball(s), set the Frequency (slider or above type the number manually) lower. For trainings with a specific high ball (Bandeja - Volley), often the volley is at the right frequency but for the high ball (Bandeja) you need more time before the next volley will be shot. For an extra pause after high balls, you can set an extra pause ONLY after the high ball (this extra pause is not after the volleys). Go to the Config screen and change the "Pause Level" (and save by "Write for Single" or "Write for Doubles"). The "Pause Level" adds an extra pause only after the high ball from 0 (no extra pause) to 100 (2 secs extra pause). This "Pause Level" is used in the trainings with Bandeja/Volley and Cross trainings, but not in de 2-line Bandeja/Volley because this is mainly used for 2 players and so no pause is needed.

Some balls are shot in the net

Some trainings vary the height and also you could set all trainings with different speeds. If the speed is very low, the ball won't go over the net anymore, the speed is too low. Even though, the speed migh be right for the player. Then you can set the "Net" position in the Config screen for every training. The Net position is a minimal height and, for that training, the machine won't shoot lower than this net position. So, if you lower the speed, which is the right speed for you, and then the/some balls were shot into the net then, set the "Net" position higher (for example, when the net position in the training is 20, set to 25 or 30). Remember that the ball will NEVER be shot below the "Net" position, even when the "Height" is set to a lower position! This Net position is also very useful in trainings where the height varies. If, for example, in a Random training the lowest balls were shot into the net, set the Net position higher. The lowest balls then won't be shot lower than this net position. Also when you want to train bandeja's but not always at the same height (for example between height 70 and 100), you can get use the "Random" training with a Net position set at 70 and a height of 100. Then the balls will be shot randomly between height 70 and 100, you can also set the "Width" position to als vary the horizontal position of the random balls. Also in Bandeja - Volley trainings, the Net position is very useful to set the height of the volleys. The machine will shoot high and low balls. The bandeja will be shot at the "height" position and the volleys will be shot at the Net position.

Bluetooth

Ball block(s)

Using machine

The machine is already connected with someone else

Bluetooth can only connect with one at a time. If someone else already connected with the machine, you can't connect another. You could easily check this by looking inside the machine. The board is left from the shooting wheels and, when you turned on the machine, a lamp is blinking. If the lamp is blinking very fast without any pause, nobody else is connected yet, so it should be free to connect with your app. When the lamp is blinking 2 times fast and then a pause of about 2 secs, someone else already connected with the machine.
If the light is blinking 2 times fast with a pause, you know that someone connected with the machine earlier and this is the reason that you can't connect anymore. But "someone else" could also be yourself. If you already loaded the app (or another version) on your own phone, the bluetooth connection could already have been made. If you are the only one to use the machine, you could turn OFF and ON the machine and the other bluetooth connection is then disconnected. Also you could check the other apps on your own phone or someone else in your neighbourhood, if he/she has loaded the app and made a connection.

Not connected...........................................................................................Already connected by someone
(press on picture to see)

Bluetooth is not working properly

Check the lamp in the machine. Is it blinking, after the machine has been turned on? If there is no blinking lamp in the machine, there might be something wrong with the bluetooth part of the machine. You can even check this by going to "Settings" on your mobile phone, Bluetooth, and then see if there is a "Padelshooter" name in "Connected devices" list or "Available devices" list. If the "Padelshooter" is in the "Connected devices" list, press on it and "Disconnect the device". Then, when machine is turned on, it should find the Padelshooter name and show in the "Available devices" list. You'd better contact De Racketclub to solve this.

Is bluetooth on your phone set correctly?

First, "Bluetooth" on your phone should be turned ON. At the top of your phone, the bluetooth icon (see icon at top of this subject) should be visible. Also, the PadelShooter app should have enough rights to work well. Even though the app should ask you for these rights, it is good to check if the rights on your phone for the PadelShooter app are sufficient. On your phone, go to Settings, Apps, All apps, Search for the PadelShooter app and select it, choose "Permissions". Check if the permissions "Location" (and "Nearby devices" for new Android 12 phones or higher) are allowed. If not, allow permission for it.

The shooting wheels are slippery

On some padel courts (for example the blue "Mondo" courts), small plastic pieces go into the balls and, when shooting, the ball gets hotter and the plastic melts on the wheels and forms a hard slippery layer on the wheels. This is not only on the PadelShooter machines but on ALL ballmachines. You can feel the wheels (machine off!) if these feel slippery, also the surface of the wheels are colored blue. Most outside courts are made of artificial grass (with sand in-between) and have no problems with this. To solve this, the wheels should be made more rough to have again good grip on the balls. This can be done with sand paper or (better) a round electric file. Best is to contact De Racketclub for this. Making the wheels more rough is often a temporary solution but De Racketclub has a definitive solution for this which will be done by us when you send back the machine, this solution is free but only the shipping costs you should pay.

Ball has fallen down without shooting

If a ball has fallen down when the machine is not shooting and so the shooting wheels don't work, the ball will stop before the shooting wheels and these NEVER will turn, when starting the machine. You can also feel that a ball blocks by turning the upper wheel by hand, this feels as if the wheel has a brake. ALWAYS the ball should first be removed from the guide just behind the shooting wheels (seen from the position as seen in above picture), before playing with the machine. You can do this by turning off the machine, press the shooting wheels to the most right (when standing before the shooting hole) so you can easier with your left hand pickup the ball(s) from the ball guide just behind the shooting wheels. Often, when 1 ball blocks the shooting, many other balls fall down (but aren't shot) till there are many balls in the machine and no balls could fall down anymore. All balls should then be removed before using the machine again. When there is only 1 or 2 balls in the guide behind the wheels, it could help to turn the machine opening more to the air (the same position when you carry the machine during transport with the handle) till the ball(s) roll to the back of the guide and are easier to remove. Also with only 1 or 2 balls in the guide, you can stand behind the machine and you point the shooting hole to above so the balls inside the box roll to the back of the guide and the shooting wheels then are free to turn again. Starting the machine (when pointing to above) will start the wheels turning and then you could turn the machine again in a normal position and the balls then will be shot (because the wheels have speed again to shoot then).

The reason for a ball falling down could be that a ball is in the ball hopper while transporting the machine to the court. If the ball is very close to the hole, it might fall down when moving the machine over stones or rough land.
