• 1 x NEMA 17 stepper motor

Step 9

Put two metal 10 mm screw anchors into both center holes on one end of the X profiles.

📘

Parts needed:

• 2 x 10 mm screw anchor

Step 10

Put the Motor plate with already attached motor onto the assembly and fasten it with two DIN 933 M8 x 16 bolts. Use DIN 125 8.4 washers.

📘

Parts needed:

• 2 x DIN 933 M8 x 16 bolt
• 2 x DIN 125 8.4 washer

Step 11

Put two plastic 10 mm screw anchors into both center holes on the other end of the X profiles.

📘

Parts needed:

• 2 x 10mm screw anchor

Step 12

Put the Bottom plate on this end of the assembly and fasten it with two DIN 7996 4.5x50 wood cross screws. Use DIN 125 5.3 washers.

📘

Part needed:

• 2 x DIN 7996 4.5 x 50 cross screw
• 2 x DIN 125 5.3 washer

Step 13

Take Bearing plate and put four DIN 933 M8x50 bolts in the round holes C5, C6 and slot holes B1, B2. Make sure to use DIN 125 8.4 washers also on the back side of the plate. On the front side of the plate put parts on each of these bolts in the following order: washer DIN 125 8.4, hex nut DIN 934 M8, bearing 608ZZ, then again washer DIN 125 8.4, hex nut DIN 934 M8, bearing 608ZZ, and in the end washer DIN 125 8.4 with hex nut DIN 934 M8.

📘

Parts needed:

• 1 x Bearing plate
• 4 x DIN 933 M8 x 50 bolt
• 8 x DIN 934 M8 hex nut
• 16 x DIN 125 8.4 washer
• 8 x 608ZZ bearing

Step 14

For the bolts in holes C5 and C6 - tighten all the nuts firmly.

For the bolts in slot holes B1 and B2 - do not tighten the nuts too firmly because we must adjust their position precisely in later steps.

Step 15

Take printed part Nut casing – Bottom and put DIN 562 M3 square nut into the square slot.

📘

Parts needed:

• 1x Nut casing – Bottom
• 1x DIN 562 M3 square nut

Step 16

Put DIN 934 M8 hex nut into the hex shaped hole on the part Nut casing – Bottom.

📘

Parts needed:

• 1 x DIN 934 M8 hex nut

Step 17

Take parts Nut casing – Bottom nad Nut casing – Upper and put them together as shown on the picture. Put hex socket bolts DIN 912 M3 x 35 and DIN 912 M3 x 16 through 3 mm holes on both parts.

📘

Parts needed

• 1 x Nut casing – Upper
• 1 x DIN 912 M3 x 35 bolt
• 1 x DIN 912 M3 x 16 bolt

Step 18

Screw bigger bolt DIN 912 M3 x 35 into M3 square nut which is already inserted in Nut casing – Bottom. Screw smaller DIN 912 M3 x 16 bolt with DIN 934 M3 hex nut.

📘

Parts needed:

• 1 x DIN 934 M3 hex nut

Step 19

Put four DIN 912 M4 x 16 hex socket bolts in four 4 mm holes (A1, A2, A3, A4).

📘

Parts needed:

• 4 x DIN 912 M4 x 16 bolt

Step 20

Fasten the Nut casing assembly onto these four bolts with four DIN 934 M4 hex nuts as shown in the picture.

📘

Parts needed:

• 4x DIN 934 M4 hex nut

Step 21

Put assembly with X profiles on bearing plate between bolts with bearings. Make sure that stell round rods are in the middle of two bearings on each bolt.

Step 22

Fasten the nuts on the bolts that are located in the slot holes B1 and B2. It is important that bearings sit tight on the steel round rods, so make sure to press it hard with spanners when fastening the nuts. If all the bearings are not sitting tightly with round rods, then try using a hammer before fastening the nuts firmly.

Step 23

Fasten the Coupler (5 to 8 mm) on motor shaft.

📘

Parts needed:

• 1 x 5-8 mm coupler

Step 24

Screw the M8 x 200 threaded rod through the M8 nut in Bearing casing up to the Coupler. Fasten the M8 rod in the 8 mm hole on the other side of the Coupler.

📘

Parts needed:

• 1 x M8 x 200 threaded rod
