Hello there! Before you start autorouting, please set the DRC rules. Min track width: 10mil / 0.254mm Min clearance: 10mil / 0.254mm Min via diamaeter: 23mil / 0.58mm Via drill diameter: 11mil / 0.28mm Then change U3 to R3 because this is a resistor, not a chip. Change U4 to J4 or MOTOR because this is a connector, not a chip. Designator U is always meant for integrated circuits or modules. As you can see, there are several tracks way too close to other tracks and pads. You should adjust these tracks so that they do not interfere or almost getting shorted to other tracks or pads. Power track widths should be much more larger than 0.254mm, so change your power tracks to somewhere 0.5mm or higher. Also ground tracks should be thicker or install a ground copper area to top and bottom layer. Motor tracks require also much more current, so these needs to be adjusted to higher track width. If you install ground copper areas, please add additional ground vias to ensure good galvanic connection from top to bottom. You could also bring the whole LM2596 module on the board. There is several user contributed parts in the library for it. Also note that the switches needs a debouncing capacitor between the signal and ground. 47nF - 100nF capacitor should do the trick. You would need decoupling capacitors for each IC and module. U1 needs 10uF and 100nF capacitor. Also Arduino would need those same capacitors at +5V input. I believe with these fixes you get your board working. Regards, Markus Virtanen HW / Electronics Designer

you probably need to rotate 3D model by 180 deg, but beware that you'll need to flip the mirror of the footprint as well.

Hi. Text objects have an anchor location, and that's what you save in a footprint. On an actual design the text anchor is placed as on the footprint, but if text has different length, it will be shifted. If you want to keep it centered, change anchor to be in the center of the text.[Picture]
