Can this work for tennis racket: 18 - 22 kg?

[206cc]

Absolutely! The 3D-printed version can handle up to 70 lbs (about 32 kg) of tension, so it's totally fine for tennis rackets in the 18–22 kg range.

Thanks I am getting ready to work through EP.1 to EP.3 for the tennis version.
Looking to purchase the following. Could you please review the parts first before I purchase?

• Raspberry PI Pico H

• CBX/SGX 1605 ballscrew 200MM sliding table Do you recommend the included stepper motor?

• NEMA23 57x56 stepper motor (2-phase 4-wire 1.8° 1.2Nm)

• TB6600 stepper motor driver Do I still need if included above?

[206cc]

1. Raspberry Pi Pico H (pre-soldered pin version) is the correct choice.
   It's much more convenient for wiring and installation. This version is recommended.

2. For the SGX 1605 ballscrew linear stage:

   • It is recommended to choose a version with a bearing seat, which provides better stability and durability under tension. See the reference section: https://github.com/206cc/PicoBETH/blob/main/docs/2.Hardware_Setup.md#linear-stage
   • The included motor can be used as long as it meets the 56×57mm, 1.2Nm NEMA23 specification. No need to purchase a separate one if it matches.

3. The TB6600 stepper driver needs to be purchased separately.

   • Some TB6600 drivers may produce a faint electrical noise from the motor when idle (this is normal in use). If this occurs and you find it bothersome, consider buying from another vendor.
     Please avoid the DM524 driver—some people have mistakenly bought it, but it is not compatible.

Additional suggestions:

1. It's a good idea to get a breadboard. It will be very useful for testing during EP.2 and EP.3.

2. After completing each EP, purchase the required materials for the next one.
