So far, the whole printer is built up, you can tidy up the wires with the zip ties and the coil wire.  
  
−
*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.
+
Before even attempting the first print it is vital that the printer is correctly calibrated. Skipping or rushing this step will result in frustration and failed prints later, so it is important to take the time to make sure the machine is correctly set up.
  
−
[[File:8. Right Z motor mount2.jpg|500px]]
+
Each machine may have its own calibration procedure and this manual will not attempt to cover all the variations. Instead here is a list of key points that should be addressed.
 +
*Frame is stable and correctly aligned.
 +
*Belts are taut.
 +
*Bed is level in relation to the path of the extruder.
 +
*Filament rolls freely from the spool, without causing too much tension on the extruder.
 +
*Current for stepper motors is set to the correct level.
 +
Firmware settings are correct including: axis movement speeds and acceleration; temperature control; end-stops; motor directions.
 +
Extruder is calibrated in the firmware with the correct steps per mm of filament.
 +
The point regarding the extruder step rate is vital. Slic3r expects that the machine will accurately produce a set amount of filament when told to do so. Too much will result in blobs and other imperfections in the print. Too little will result in gaps and poor inter-layer adhesion.
  
−
*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.

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.

  • 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.

Prusal I3 manual pic78.jpg

So far, the whole printer is built up, you can tidy up the wires with the zip ties and the coil wire.


Before even attempting the first print it is vital that the printer is correctly calibrated. Skipping or rushing this step will result in frustration and failed prints later, so it is important to take the time to make sure the machine is correctly set up.

Each machine may have its own calibration procedure and this manual will not attempt to cover all the variations. Instead here is a list of key points that should be addressed.

  • Frame is stable and correctly aligned.
  • Belts are taut.
  • Bed is level in relation to the path of the extruder.
  • Filament rolls freely from the spool, without causing too much tension on the extruder.
  • Current for stepper motors is set to the correct level.

Firmware settings are correct including: axis movement speeds and acceleration; temperature control; end-stops; motor directions. Extruder is calibrated in the firmware with the correct steps per mm of filament. The point regarding the extruder step rate is vital. Slic3r expects that the machine will accurately produce a set amount of filament when told to do so. Too much will result in blobs and other imperfections in the print. Too little will result in gaps and poor inter-layer adhesion.
