added the lower wheels.

motor and lower wheels with erratic offsets

adding top wheels.

managed to switch the camera to double pic mode..

i found it easiest to put the wheels together this way, bearing, bolt.

then add washer, and next bearing

right side gantry plate

mounting them on the rail, pull out bolt til its flush, put the wheel in the V and push bolt into hole on plate. sorry about blurrycam.

All mounted, time to adjust the eccentrics and have it slide and not have up and down movement.

the right side upper wheels don't seem to be properly aligned holes or such, since two engage, and two ride free.

OK, next cross beam and then the Z section after some more coffee.
