Asking for help programming servos for my wedding lightsaber build

[hkwwinger]

Is this an analog or digital servo? 50Hz PWM?

@hkwwinger

Is this an analog or digital servo?

Digital aparently: Amazon.com: 4-Pack Servo Motor MG995 Control Angle180 Metal Gear Servo 13KG Digital High Speed Torque Servo Motor for DIY Smart Robot Toys RC Toy Car Model Helicopter RC Boat : Toys & Games
I also tried tried one of these: Amazon.com: Sg90 9g Micro Servo Motor, Miuzei Mini Small Servos Motor Kit Metal Gear for Arduino RC Car Airplane Robot (10) : Toys & Games which is analog and also had no jitter.

@hkwwinger

50Hz PWM?

yep

[hkwwinger]

Could you let me know how your servo is wired. My first goal will be to replicate your positive results.

Thank you. As always, I appreciate your knowledge and help!

Servo+ ↔ BATT+
Servo- ↔ BATT-/GND
Servo Data ↔ Free3

It might be worth mentioning that the other person who had jitter tried a different board and the jitter went away:

Blaster Servo Help

I was too impatient. I rewired a new board because “why not?” Works flawlessly. Definitely the other board sending bad signal. Thanks for all the input, @profezzorn. I’m still going to potentially try the newer servos before finalizing this blaster build, but thought it helpful for other folks following the thread to know some Proffies are sending subpar signals, and to try another or get them from more reputable sources before giving up on your builds.

Returning to this, It’s possible that this is my issue as well. the board I am struggling with this on is from aliexpress.

I’ll purchase another one, where would you recommend getting it from? I see tritium and TCCS are out of stock at the moment.

The Saber Armory/KR Sabers would be my next suggestion.

[profezzorn]

This would be my recommendation as well.
