EShapeoko 1.0 and 1.1 Assembly Instructions
Step 0: Prep work
- Deburr the ends of the MakerSlide, especially the Vs. The Vs should have no protrusions, because they can damage the wheels. 200 to 400 grit sandpaper for metal works fine; a small, fine metal file may help too.
- Tap all the end holes in the MakerSlide M5×0.8mm (standard M5 thread), except the Z rail, which needs only one end tapped. Brush chips away and wipe the rail clean, to prevent damage to the V-wheels.
- Tap the round holes in the belt tensioners, also M5×0.8mm.
- Mark the side nearest the hole in the eccentric spacers by colouring it with a Sharpie or with a tiny dab of paint. The wheel will be offset in the marked direction.
During the build, pay attention to the washers: follow the instructions exactly.
Step 1: Assemble the V-wheels
| Item | Part Number | Part Description | Count |
|---|---|---|---|
| For each wheel | |||
| 1 | EM-MW1 | V-wheel sleeve | 1 |
| 2 | EM-G5 | 5 x 16 x 5mm bearing | 2 |
| 3 | EM-W5P | 5mm precision washer | 1 |
Lay one bearing on a flat surface. Push a V-wheel sleeve over it. The parts are designed to force-fit, so push firmly straight down. Thread this on a long M5 bolt, bearing side first, followed by a precision washer and the second bearing. Place the second bearing on a flat surface, and push the V-wheel sleeve over it too. Make sure both bearings are in as far as they will go. Remove the bolt.
Repeat 16 times (20 if you have the dual-X upgrade).
Step 2: Assemble the smooth idler wheels
| Item | Part Number | Part Description | Count |
|---|---|---|---|
| For each wheel | |||
| 1 | EM-MW2 | Smooth idler wheel sleeve | 1 |
| 2 | EM-G5 | 5 x 16 x 5mm bearing | 2 |
| 3 | EM-W5P | 5mm precision washer | 1 |
Lay one bearing on a flat surface. Push an idler wheel sleeve over it (lip up, of course). The parts are designed to force-fit, so push firmly straight down. Thread this on a long M5 bolt, lip side first, followed by a precision washer and the second bearing. Place the second bearing on a flat surface, and push the idler wheel sleeve over it too. Make sure the bearings are all the way in, with the first bearing resting against the lip of the sleeve. Remove the bolt.
Repeat 6 times.
Step 3: Mount the V-wheels on the right Y panel
| Item | Part Number | Part Description | Count |
|---|---|---|---|
| 1 | EM-LMP | Motor mount plate | 1 |
| 2 | Assembled V-wheel | 4 | |
| 3 | EM-MES | Eccentric spacer | 2 |
| 4 | EM-S5-30 | M5 30mm cap screw | 4 |
| 5 | EM-W5 | M5 washer (form A) | 12 |
| 6 | EM-N5 | M5 hex nut | 4 |
The top wheels (marked A in the image) are fixed, the bottom ones (B) are adjustable. Put a washer on each bolt. For the bottom wheels, also add an eccentric spacer. Check the drawing for the correct orientation of the plate. Insert the bolts into the holes. For now, position the eccentric spacers so that the top and bottom wheels are furthest apart (marked face toward the bottom). On each bolt, add a washer, a V-wheel, another washer, and a nut.
Step 4: Mount the motor and the idlers on the right Y panel
| Item | Part Number | Part Description | Count |
|---|---|---|---|
| 1 | Assembled idler wheel | 2 | |
| 2 | EM-S5-30 | M5 30mm cap screw | 2 |
| 3 | EM-W5 | M5 washer (form A) | 6 |
| 4 | EM-N5 | M5 hex nut | 2 |
| 5 | NEMA17 stepper motor | 1 | |
| 6 | EM-BP5 | 18-tooth MXL pulley 5mm bore | 1 |
| 7 | EM-S3-30 | M3 30mm cap screw | 4 |
| 8 | EM-W3 | M3 washer (form A) | 4 |
| 9 | EM-D3-15 | M3 23.81mm spacer | 4 |
Please note that in some kits, the EM-D3-15 spacer is replaced by one EM-D3-12 spacer and three EM-W3N washers each.
