Four drives, feet, tensioned belts, closed cams and labelled cables. Deck captured by its eight clips, the frame back upright on its feet without rocking.

What you're looking at

Manual p.47: all four corners done. Two corners take the _a hand of every printed part, Z0 and Z2, and two take _b, Z1 and Z3. The cable labels go on now because in Ch 10 four identical black stepper cables arrive at the mainboard together.

pause Good stopping point · ~55 min since the last one

since the last pause, in three ~18-min corners — Z1, Z2 and Z3 built and fitted the same way. Stop after any corner whose four M5 bolts are tight, tensioner closed and foot fitted; never with a cam open and the motor free to slide. All four cables labelled Z0–Z3 by physical corner, and the printer back upright on its feet.
