Thnaks and Damn to who boycott a country! And is there any code for plotter with both uln2003 and esp32?

To configure 28byj needs to use unipolar driver

here is example

  x:
    steps_per_mm: 80
    max_rate_mm_per_min: 500
    motor0:
      hard_limits: false
      unipolar:
        phase0_pin: gpio.13
        phase1_pin: gpio.12
        phase2_pin: gpio.14
        phase3_pin: gpio.27
        half_step: false

and try to use servo settings like in WallPlotter.yaml config example
