The ESP32 and the motionboards are now compacted onto one single 4 layer PCB.

The board provides an output for a 12v fan and some dip switches to set the microsteps for XY and the spindle.

Only the z-axis uses software controlled microstep settings. XY and the spindle use fixed microstepping.

This should make the wiring a lot easier.
