Servo Plugin - for Pen Plotter

[ghost]

Hi Team,

I was wondering if anyone has thought about creating a Servo Plugin that can be used for a Pen Plotter.

I can build the hardware but do not know how to program the code to support a servo output.

Regards
George

Check the drivers readme for RC Servo/ESC for spindle support:

¹³ Set $33=50 (PWM frequency), $34=5, $35=5 and $36=10 to generate a "standard" PWM signal: 20ms repetition rate, 1 - 2ms pulse length range.

Hi terjeio,

Thanks for pointing this out.

I found that it did not work until I changed the frequency to 61Hz. Playing around with the min / max levels allowed for the servor arm to travel further.

Cheers
George

Which driver are you using?

STM32F401. After tweeking the settings the servo works really well. Cheers George
