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.

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

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

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

8. 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.

Step2. Thread the M3X30 screw through the two plates and add washers and spring at this end.

Step3. Lock the other end with a wing nut.

Here is the finished picture.

Chapter 2 Top Plate Assembly

endstop mount

Step1. Mount the three end stops onto the Endstop mount (A6), screw with M3 X 16 screws. You may need to use some force to do this.

Step2. Mount the assembled parts onto the top plate. Screw up with M3 x 16 screws and M3 square nuts. Note the directions of the endstop.

Drive wheel mount

Step1. Mount the Drive wheel mount on A1; screw them up with M3 X25 screws, M3 nut and washers.

Step2. Thread the M3 x 16 screw through the driven wheel holder.

Step3. Put the M4 x25 screw through the holes with the two 624ZZ bearings in between. Lock the other end with a M4 lock nut.

Step4. Mount the assembled driven wheel holder onto the top plate. And screw it with a wing nut. Pay attention to the direction of the driven wheel.

Repeat the above 4 steps for the other 2 driven wheels.

Mount the extruder

Find out the locating holes on the top plate; screw up the extruder with 4 M5 x 16 screws and 4 washers.

The screws are bottom - up.

Note: If your are assembly the G2s, you will need another 4 M5 x 16 screws and 4 washers to mount another the extruder.

Mount the spool holder

Screw up the spool holder panel on the top plate separately with M3X16 screw and M3 nut and washer.

Through the spool holder rod into the panel, or you can do it later after you finish the building.

Chapter3 mount the smooth rods

Step1. Insert the smooth rods into the slot on the base plate; put a M8 washer on the end of the rod.

Step2. Screw up the rods with M4x 25 screws and M4 nuts.

Repeat the above two steps for other rods.

Step3. Slide the 6 linear bearings into the 6 smooth rods separately.

Step4. Put a M8 washer on each top end of the rods and cover the top plate on the rods, screw them up with M4x 25 screws and M4 nuts.

Chapter 4 Assemble the print platform

Step4. Connect the assembled print platform to the smooth rods.

Mount the carriage onto the rods where the linear bearing is, insert the bearings into the slot.

Step5. Tie up the carriage and the bearings with two zip ties.

To help you see clearly, here is a detailed picture for the carriage.

Chapter5 Mount the Belt

Step1. Thread the belt through the drive wheel end. Pull it down to the pulley.

Step2. Thread the belt around the pulley, and take both ends to the carriage.

Step3. Insert the belt into the slot. If the slot is too thin, you can use the grater to file it larger. Tie up the belt if needed.

*Pay attention to the tooth mesh of the belt and that on the bracket. Tie up both ends tightly.

*The belt should be neither too tight nor too loose, you can slide the carriage up and down to see if it is.
