3D printer manual - Mike 2
1. intended use
The 3D inlay printer Mike 2 is a Fused Filament Fabrication (FFF) 3D printer. Its purpose is to print digital 3D models of insoles, which are created in the software GP Manager InsoleCAD The process is designed to transform the moulds into physical objects (inserts) by depositing molten thermoplastic material (known as filament) layer by layer.
The printer has been specially designed to work with the filament Addigy® FPU 79AR8 of the company Covestro developed. Although the printer accepts other filaments (brand and/or material type), the use of these filaments does not provide optimal results and in some cases can lead to permanent damage to the machine.
Warning: Using filament that has not been authorised by the manufacturer/sales representative will invalidate the printer's warranty.

|
| |
An earthed main socket must be used. Ensure that the building installation has special means for overcurrent and short circuit.
|
 |
Always disconnect the appliance from the power supply before carrying out maintenance and service work, unless otherwise specified.
|
|
Only trained personnel should reach into the control chamber of the machine (accessible from the bottom cover of the machine), with the electrical and electronic parts.
|
|
Do not place any objects filled with liquids, such as vases or cups, on, around or in the machine. Take care not to pour any liquids into the system. They can cause a breakdown and/or fire hazard.
|
3.2 Mechanical safety
Keep away from the drive belts at all times. There is a risk of pinching during operation.
| The 3D printer Mike 2 contains moving parts. The force of the print bed is great enough to cause damage, so stay away from the print bed during operation.
Keep away from the drive belts at all times. There is a risk of crushing during operation.
|
|
 |
|
|
Always unplug the appliance before carrying out cleaning or service work, unless otherwise specified. |
3.3 Risk of burns
 |
There is a potential risk of burns as the nozzle/print head can reach temperatures in excess of 200°C. Do not touch the nozzle with bare hands.
Unless otherwise specified, always allow the machine to cool down for at least 20 minutes before carrying out maintenance work or modifications to the print head. |
3.4 Magnetic field
 |
Static magnetic field hazard. Due to the static magnetic field caused by the magnets in the printer, keep a distance of at least 4 cm between implanted electronic medical devices and implants that contain ferromagnetic materials. |
3.5 Emission hazard
Thermoplastics for 3D printing can lead to the release of ultra-fine particles (UFPs) and volatile organic compounds (VOCs), depending on the thermoplastic used and the settings of the 3D printer. Above certain concentrations (threshold values, TLV), these emissions can pose a risk. The concentrations are influenced by the filament and adhesive used, the printing conditions (e.g. printing temperature), the room volume, the air exchange rate (AER) and the number of printers in a room.
Depending on your specific situation, please observe other safety measures, such as a filter and/or a special ventilation system.
The use of printing materials / filaments from different suppliers may require additional safety measures. Always refer to the relevant information from the supplier of such filaments/materials and the safety data sheet of each specific material.

- an empty coil is to be replaced with a new coil
- a spool is to be inserted into a printer that does not contain filament
- filament is to be removed from the printer.
7.2 Preparation Insert filament
7.2.1 Inserting the filament spool
| When inserting a filament spool into the filament chamber, the spool must be aligned correctly to avoid problems.
The spool should be installed so that the filament is unrolled from the top, as shown in the illustration. |
 |
7.2.2 Checking the lever position
| To ensure that the extruder is ready for printing, the lever should be in position 3. In this position, 3 notches are visible |  |
7.2.3 Attaching the filament tube
| Insert the 10 cm hose into the print head inlet. |  |
7.2.4 Inspection of the filament
| Before inserting the filament into the print head, make sure that the end of the filament does not have a "defect", as this may result in the filament not being able to be drawn properly.
If the cut edge is not clean and straight, cut it with scissors, side cutters or another cutting tool. |
  |
7.3 Insert filament/change filament process

8. print bed calibration
8.1 What is print bed calibration?
It is an essential requirement of the 3D printing process that the print head is always at a constant distance from the print surface (print bed) when printing the bottom layer of the object.
If the gap is too large, the extruded material will not stick to the printing surface and will be pulled around by the head.
If the gap is too small (or the head and bed are touching), the material will not come out of the nozzle, which can lead to clogging. (The material will get stuck in the head and additional maintenance will be required to bring the printer back to an operational state).
The 3D printer Mike 2 has an algorithm for correcting inaccuracies in the alignment of the print bed. However, it is sometimes necessary to adjust the reference height parameter (starting point) with the help of the user.
8.2 To check whether the print bed is correctly aligned
A test pressure can be used to check whether the bed is correctly aligned. To do this, carry out the following steps:
| 1 | Open the menu Settings, by pressing the settings button (1). | 
|
|
2 |

|
 |
|
4 |
Select the print temperature of the print head for the test print. Change the target temperature (3) of the test pressure via the top (4) or bottom (2). If you use the standard filament Addigy® FPU 79AR8 is 265oC the correct value. Press the confirmation button (6) to start. Press the cancel button (1) to go to the main menu. Press the Back button (5) to return to the Print bed calibration to return.
|
 |
|

- Extruded filament is clear and transparent. Test print failed - Uneven extrusion - Large parts without extrusion - Material stuck to the print head and not to the print bed. If the test print fails, carry out the print bed calibration (see below).
|
|
8.3 Print bed calibration
The menu Print bed calibration offers the possibility to optimise the print bed position of the printer in order to achieve better adhesion (bonding) of the extruded material to the print surface.
Attention: Before you start this procedure, make sure that the temperature of the print head below 80 oC and the Nozzle is clean (see section 14).

1. press the "Reference point" button (2). The print head moves to the reference point, takes a measurement and moves the print head and the print bed to its "zero" position.The offset value (7) for Mike 2 should lie between -0.4 and - 1.2. If the measured value is outside this range, please contact support before proceeding. Note: (3) and (4) are calibration points that are used during maintenance (see chapter 2. take a piece of paper (normal printer paper, from a notepad, etc.) and carefully try to push the paper between the print head and the print bed without using too much force. 3. if it does not fit (distance is too small), use the down arrow (6) to move the print bed downwards until the paper fits in between. WARNING! Do not apply any force to the print bed by hand during this process. 4. the paper is now between the print head and the print surface. Move the paper slightly back and forth while moving the bed upwards one step at a time using the arrow (8) (each step is 0.05 mm). 5. press the down arrow once (6). 6. confirm the new removal by clicking OK (9). Press the cancel button (1) or the back button (5) to cancel the process (no changes are saved).

14. regular service/maintenance
To ensure that the printer continues to print as expected, regular cleaning is recommended. Both the print bed and the print head must be cleaned.
14.1 Cleaning the print bed
Each print leaves some oil residue from the printed material, which over time will cause printed objects to adhere less to the surface. It is recommended to clean the print surface thoroughly with isopropyl alcohol before each print to remove any oil residue (see chapter 10).
14.2 Cleaning the print head/nozzle
Cleaning the print head is an important process that contributes to the quality of the printed objects. It reduces the risk of clogging and ensures even extrusion of the filament.
Cleaning the nozzle from the outside
- We recommend that the outer tip of the print head (the nozzle) daily with the cleaning tool included in the accessory box.
Allow the print head to cool down first. Scrape the nozzle with the cleaning tool until the tip is free of filament residue. Make sure that you do not touch the inductive sensor (blue dot) behind the nozzle when cleaning it.
Cleaning the inside of the nozzle
- We recommend cleaning the inside of the nozzle every time a new filament spool is loaded. Only use approved cleaning filament for this process.
Proceed as follows:
| 1 |
Open the menu Filament changeby pressing the settings button (1). |
|
|
|
2 |
Heating up. Please wait until the target temperature has been reached. |
|
|
|
3 |
Pull the old filament out of the extruder and press the WfurtherButton (2). |
 |
 |
|
4 |
Select Yes (1).
|
|
|
|
5 |
Heating up. Please wait until the target temperature has been reached. |
 |
|
|
6 |
Feed the cleaning filament into the extruder. When the filament comes out of the nozzle, press the Further-button (2) |
 |
 |
|
7 |
In this automatic step, the temperature begins to drop as the material is extruded. Note: You may hear a clicking sound. This is normal. |
 |
|
|
8 |
In this automatic step, the extrusion is switched off and the print head is cooled down. |
|
|
|
9 |
Remove the extruded filament from under the nozzle. |
 |
|
|
10 |
Turn the lever to idle / position 0 (anti-clockwise). |
 |
|
| 11 | Grasp the cleaning filament and pull it out of the extruder. |  |
 |
| 12 | Clean any burnt residue from the nozzle using the brush supplied.
Attention! The nozzle temperature is 110 degrees! |
 |
|
| 13 | Look through the nozzle. You should be able to see through the hole. |  |
 |
| 14 | Turn the lever clockwise to position 3 and then insert new filament.
|
 |
 |
| 15 | Wait until the print head has heated up.
|
 |
|
| 16 | Insert the regular filament and when the material comes out of the nozzle, press the confirmation button (1) to complete the process. |  |
15. troubleshooting
Each problem is shown with possible causes and their solution. Go through the list in the order shown. If a problem cannot be solved, contact support.
15.1 Printed object does not stick to the printing surface
- The print surface is not clean. Wipe the print surface with isopropyl alcohol (see chapter 14).
- The print height is incorrect. Calibrate the height by following the print bed calibration (see chapter 8).
15.2 Printer does not extrude correctly
- The print bed is too close to the print head during the first printed layer. Calibrate the height by following the print bed calibration (see chapter 8).
- The printer has run out of filament.
- The filament has become entangled in the filament chamber. Check the filament in the filament chamber.
- The filament is stuck in the print head. Use the filament replacement procedure (see chapter 7) to remove the filament, cut off a piece and reinsert it.
- The print head is clogged and the print head needs to be cleaned. Carry out a cleaning process (see section 2).
- The printed part has a rough surface with small bubbles. This can happen if the filament is damp because the filament chamber is OFF or it has been stored in an uncontrolled environment.
- Check whether the filament chamber is connected.
- Replace the filament with a filament that has been stored in a dry and warm environment.
- Leave the wet filament in the (heated) filament chamber for at least one day without printing to dry it.
15.3 Object not completely or not properly printed
- The filament was empty before printing could be completed. Check whether the filament needs to be replaced.
- Printer firmware error. Check the printer screen for error messages. If the error message is not self-explanatory, contact support.
- During the printing process, there was something in the work area that was blocking the printer. Check the work area for foreign objects.
- The silicone sleeve of the print head has fallen off and is blocking the printer. Check that the red silicone sleeve is correctly attached to the print head. Make sure that the silicone sleeve is not cracked.
- The power supply to the printer was interrupted during the printing process. Check whether the printer is switched on.
15.4 Print head does not extrude and you hear clicking noises
In some cases, the filament can get stuck in the sprockets. If the regular filament change does not help, proceed as follows:
| 1 |
Turn the lever to idle / position 0 (anti-clockwise). |
|
|
2 |
Open the menu Manual controlby pressing the manual control button (1). |
|
|
3 |
Start manual heating with the Temperatures (5 and 6).
|
 |
|
4 |
Use the arrow buttons (1 and 4) to set the target temperature to 265°C and press Confirm (7) Then go back to the menu Manual controlby pressing "Back" (5).
|
 |
|
5 |
Press and hold the up arrow of the extruder (3) for 5 seconds while pulling. Then press and hold the down arrow of the extruder (3) while continuing to pull. The filament should come out after 5-10 seconds.
|
 |
|
6 |
Cut off the deformed piece of filament. Set the lever back to position "3". Call up the menu Filament change and follow the instructions to insert the filament. |
 |
If the filament comes out but clogs again after another print attempt, clean the print head.
If the solution does not help and the filament is still stuck, contact cubix@gebiom.com.
