Safety Instructions

Building the printer will require a certain amount of physical dexterity, common sense and a thorough understanding of what you are doing. We have provided this detailed instruction to help you assemble it easily. However ultimately we cannot be responsible for your health and safety whilst building or operating the printer, with that in mind be sure you are confident with what you are doing prior to commencing with building or buying. Read the entire manual to enable you to make an informed decision. Building and operating involves electricity, so all necessary precautions should be taken and adhered to, the printer runs on 12V supplied by a certified power supply, so you shouldn’t ever have to get involved with anything over 12V but bear in mind there can still be high currents involved and even at 12V they shouldn’t be taken lightly. High temperatures are involved with 3D Printing, the Extrusion nozzle of the hot end can run about 230°C, the heated bed runs 110°C and the molten plastic extruded will initially be at around 200°C, so special care and attention should be made when handling these parts of the printer during operation. We wouldn’t recommend leaving your printer running unattended, or at least until you are confident to do so. We cannot be held responsible for any loss, damage, threat, hurt or other negligent result from either building or using the printer.

Preparation

1. Unpack the kit and check if all parts are in the box and check the condition of each part, there might be some damage during shipping. To help you with this, there is BOM in the box and each bag was labeled with part number.

2. Contact our customer service immediately by email or through the website if you find any missing or damaged parts. And on the bottom of the BOM, there is a signature of reviewer, please take a picture of it and attach the picture in your mail.

3. Read through each chapter of these instructions to gain an over-all idea of what is involved and how long it might take, before starting on the work described. Or you can watch the video here.

4. Before you start, you can put all the part in order to save your time especially those screws and nuts. Do not mix them up.

5. Some printed parts may need more filing than others to ensure a secure fit when screwing together. Please do not over file a part, it is best to remove a small amount of excess plastic and test the fit then re-file as necessary. No excessive forces should be required to bring parts together.

6. Ensure you have the necessary skills to carry out the work, or enlist the help of someone who does.

7. Work on a big firm table or bench in a clean dry well-lit area.

8. This kit contains tiny parts; please keep them away from kids under 3.

9. Ask for help if you run into any problems - our contact details are on the website and we will always do our best to resolve any problems encountered.

Unfold the box and check the package list

Unfold the package and take all the parts out to check the condition of the items.

• All the acrylic plate has been etched with part ID and the plate is covered with a sheet of kraft paper, you need to tear them off.

• The part ID is corresponding to the number labeled on the bag of every part. Some parts may not have label, you can refer to the pictures on the package list.

=Assemble the threaded rods of Y axis=

Thread the nuts and washers into the two M10 threaded rods separately. The order should be:

Watch the Video here.

Assemble the front and back support of y axis.

Thread the plate to both end of the threaded rod in the following order:2

Front outside support plate: No.A9

Front inside support plate: No.A10

Rear outside support plate: No.A12

Rear inside support plate: No.A11

Screw up the threaded rods and support plates with M10 nut and M10 washer at both end. Hand tighten the M10 Nuts against the M10 Washers. Try to keep the rods parallel and the four acrylic pieces parallel.

• Tips:

the Y-axis must be a rectangle, that is the rods on both side should be parallel, so is the front and back plate. Otherwise it will cause obstruction for the belt later.

You can watch the video here.

Thread the smooth rods and linear bearings.

Thread the smooth rod into the Y axis support plate from rear to front, and thread the locking ring and 2 SCS8UU Linear Bearing on the smooth rod in turn.

Screw up the locking ring

Mount the Y motor

Step1. Mount the pulley on the motor shaft, one of the screws should be screwed on the cross section of the shaft. Screw it tightly.

Step2. Then screw the motor on the Y motor holder with 3 M3 x 12 screws and M3 washers.

Step 3. Push the Y Motor holder tab into the square hole in Rear -Outside Plate and Rear - Inside Plate. You may need to use a little force, but be careful not to break or crack any of the Acrylic pieces. Secure the Y Motor holder with 2 M3x16mm Screws , 2 M3 Washers and 2 M3 Square Nuts.

You can watch the video here.

Y belt driving wheel

Step1. Thread the M3 x 20 screw and M3 washer through the Driven wheel holder .

Step2. Insert the two MR84zz ball bearings into both ends of the driven wheel.

Step3.Put the M4 x25 screw and M4 washer through the driving wheel. Lock the other end with a M4 lock nut. You may need a wrench to tighten locking nut.

• Do not screw it too tight, you should leave enough room for the wheel to turn freely.

Step4. Mount the assembled bearing holder onto the front support plates. And screw it with a wing nut.

Look at this picture, the driving wheel and the pulley should be in a straight line. You can refer to the video here.

Build the print platform

Step1. Mount the belt mount at the middle of the building platform support with 2 M3 x12mm screws and M3 washers.

Step2. Mount the the building platform support on the 4 SCS8UU linear bearings on the rod with M4x16mm screws and M4 washers

• Note the direction of the building platform support, you can judge from the direction of the belt mount, whose direction is corresponding to the Y axis.

You can refer to the video here.

Mount the Y belt

Step1. Punch a M2.5 hole on one end of the belt (the hole can be as the diameter of the M2.5 screw , leave enough margin)

Step2. Fix the belt on one side of the belt -mount with a M3 x 8 screw and washer(.

Step3. Thread the belt around the pulley on the motor and the driving wheel.

Step4. Taut the belt to determine the length of the belt, punch another hole and and fix the other end of the belt mount with a M3 x 8 screw and washer.

Step5. Cut off the rest of the belt

• Tips: 

1. Before you drill your second hole, make sure to pull belt tightly to find the  proper placement of hole for a tight belt, if it is too loose, it will hinder the move of the print platform.

2. Loosen the Y idler wing nut when tightening belt onto the Y belt mount  in order to make securing the belt to the block easier. Be sure to tighten wing nut fully  once done.

3.The belt should be vertical with the Y axis support plate.

Left Z motor mount

Step 1. Insert the A6 and A7 into A5, note the detail:A7 is on the left and A6 is on the right.

• Note the direction of the A4,the small round hole is on the left.

Step 2. Fix the assembled motor mount on the left-bottom of A1 with M3 x 16mm screw, M3 and square nut.

*Be very careful here, if you can not insert them into the hole you can loose the screw on the motor mount and try again. 

Watch the video here.

Right Z motor mount

Step1. Assemble the 2 A6 and A5 together, screw up with 3 M3 x 16mm screw ,M3 washer and M3 Square nut .

• Note the direction of the A5,the small round hole is on the right.

Step2. Fix the assembled motor mount on the right-bottom of A1 with M3 x 16mm screw, M3 washer and M3 Square nut.

• Be very careful here, if you can not insert it into the hole you can loose the screw on the motor mount and try again.

Watch the video here.

Side panel assembly

Fix the side panels on A1 with M3 x 16mm screw, M3 Square nut and M3 washer. Watch the video here.

If the tab doesn’t fit the hole, there must be some manufacturing faulty, please use the file to trim it.

Mount the Z motors

Step1.Thread the wires of the motor through the holes on the bottom of A1.

Step2.Screw up the motors on A5 with 4 M3 x 12 screws and M3 washers. Mount the other Z motor on A4 in the same way.
