STEP 5: Spring Loaded Drive Assembly

Insert two M5 nuts as shown. Insert the spring and washers if necessary. The spring has to be preloaded in order to eliminate axial play.

Count	Name
1	Spring (ID min. 6mm)
2	Nut DIN 934 M5

STEP 6: Clip in Alpha Axis Assembly

Clip the Alpha Axis Assembly to the LM8UU bearings of the bottom frame.

STEP 7: Clamp Y Axis Rods

Assemble as shown. To clamp down the rods insert M3 square nuts in the respective slots and tighten the upper clamp parts down with M3 screws.

STEP 8: Spring Loaded X Axis

Assemble according to Step 5.

Count	Name
1	Spring (ID min. 6mm)
2	Nut DIN 934 M5

STEP 9: X and Y Axis Drive Assembly

Thread the M5 rods through the spring laoded x- and y-axis drives and add two M5 nuts before the 3D-printed holders in order to secure against pulling the rods out. Tighten the pair of respective M5 nuts against each other. Add a M3 nut to each of the BOT_HANDWHEELS’s slots and secure the handwheels to the end of the rods by tightening the M3 set screw.
