5th day: getting ready for the first testings
we have now mounted motors in the X, Y and Z direction — all wires have been soldered neatly to parallel port plugs — so we are basically ready for the initial testings, just need to figure out to cable the stepper motors to the motor controller with no motor datasheet (we threw that away 
)
we have mounted the motors on pieces of standard metal U profiles found in the dump. for practical reasons the motors for the y&z-directions are positioned skewed in a 45 degree angle.
to transmit rotation from the motors to the shafts we have used flexible hose with the right diameter - they actually fit so tightly, that we can use them as they are with no further tightening — this will also provide us with a mechanical clutch, securing the motors and frame, if we do faulty programming in the initial testing phase. using flexible hose as connectors has the advantage of compensating for minor imperfections in our homemade motor mounts.
