     172=== New steppers arrived
    171173New stepper [https://www.pololu.com/product/2133 DRV8825] motors has arrived. First reduced rating to roughly 1A per [https://www.youtube.com/watch?v=89BHS9hfSUk instructions of Claire from Pololu]. I do not like the new 1/32 stepping setting, not many people are using it and it seems rather useless on my low-resolution printer. Hence the jumpers below the stepper drivers are removed, only M2 (3th jumper from the left) is left.

     176=== Demo printing again
     177The demostration print accedentally printed using setting from an other printer. The result how-ever looks much smoother, which seems rather odd since the nozzle is completely different.

     179=== Step size issues
     180The demostration print as perfect diamentions on X and Y (20mm), yet the Z axis is not correct. Instead of 5mm it is roughly 3mm. Some tweaking on STEP sizes needs te be done using [http://marlinfw.org/docs/gcode/M092.html M92] as starting point.
