Assembly manual
General advice:
For the assembly of many components of the iFactory One, so-called T-nuts are used. The T-
nuts need to be pushed into the profiles groove. This only works if the T-nut is in the correct
position, as shown in [Picture One].
Once the T-nut is in the groove and the component is in place, the screw can be tightened. To create
the desired clamping, the T-nut must be turned 90° as shown in [Picture Two].

Page 2: Aligning The Wheels
It may happen that the T-nut does not turn in the groove when the screw gets tightened. If this happens, you have to turn the screw back a little (do not turn the screw all the way out because then you will lose the nut!) and then tighten it again until the T-nut produces the desired clamping. - Page 3 Try loosening the bolt on the other side at the wheel. If this is an option (use the hex key in the way you can apply the most torque) you can fasten it again, when you have placed the x rail onto the frame. Fastening the bolt again auto realigns the wheel (it rotates along with the bolt until the wheels hits the rail).

- Page 35 Step 9 assembly of core XY movement system: Y stepper motor X stepper motor 2x gt2 belt Mount the Y stepper motor to the upper profile on the side of the R slider. Mount the X stepper motor to the upper profile on the side of the L slider. Then attach the guide rail with the printhead to the rear aluminum profile.
- Page 36 The other gt2 belt runs around the geared belt pulley of the X stepper motor and then along all the other rollers on the rear side as shown in the illustration. Tension the belt to the printhead with a cable tie.
- Page 37 Y-stepper belt (belt runs over the bottom rolls) 1. The belts need high tension to have no slack in the motion system. 2. If the belts rub against each other, move the motors more outside the frame. 3. If the belts are tight, you can cut off the remaining gt2 belt at the printhead. 4.
