Pen plotter servo is acting strange

• grbl

  90 3,952 0.0 C

  An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino (by gnea)

  

To be more precise: Regular grbl: "By default, the spindle PWM frequency is 1kHz, which is the recommended PWM frequency for most current Grbl-compatible lasers system. If a different frequency is required, this may be altered by editing the cpu_map.h file." Source: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Laser-Mode#laser-mode-operation

• grbl-servo

  3 80 0.0 C

  Special Grbl version for use with servo instead of spindle or laser. (by cprezzi)

Adapted grbl: "This is a special version with servo support (swichable in config.h) The PWM frequency is set to 61Hz (prescaler 1/1024). The pulse width range is 0.5 - 2.5ms.". Source: https://github.com/cprezzi/grbl-servo
