My box measures 13.25 (H) x 6.75 (W) x 3.5 (D). The USB port protrudes the most at +.3125 above the face making total depth 3.8125". As far as cable stick out, the cable bundles are flexible and can be laid over within 1-2". But, the USB-B side of the included USB cable is rigid and will stick out 1.75" from the box face (includes the USB port).
There are two bundles that stick out the back of the machine; one for the motors and the other for proximity switches. The switch bundle measures ~30" and the one for the motors measures ~36". You’ll have some flexibility depending on your cable management strategy. There two other cables that plug into the control box, the USB and the power pendant, I didn’t opt for spindle. They measure 6’ and ~6.5’ respectively.spindle yet. Hope that helps.
