Do not forget to copy the user license of UCCNC into the UCCNC installation directory!
2.2
INSTALLING THE MACHINE PARAMETERS
After installation of the UCCNC software you need to install the appropriate STEPCRAFT machine parameters for
UCCNC. Start “Screensetinst.exe” in the /Stepcraft/ folder:
Choose your type of machine size (210 to 840) and type of machine series (Stepcraft 1 or 2) and install the 3D
print configuration to operate the 3D print head.
5
Start the installation. The installation will create a desktop icon and prepares, for example, different technical
th
parameters for the 4 axis. In the 3D print configuration a plugin will be installed additionally to control the 3D print
head.
NOTICE: You can start UCCNC in the 3D print configuration with the STEPCRAFT parameters by clicking this
icon. Always make sure that you choose the correct parameter setting / start icon for the intended machine
operation.
2.3
CONNECTING THE MACHINE TO THE COMPUTER
After completing the software installation, connect the AC adapter to the power supply and the STEPCRAFT
desktop 3D system. Connect the machine / the UC100 device with the enclosed USB cable to the computer and
launch the program:

MANUAL TEST
Please refer to item 2.7 if you are already familiar with the manual jog menu of UCCNC.
If the STEPCRAFT is in status 1/1, it can now be moved manually.
NOTICE: Furthermore, the proper assembly of the machine, according to assembly instruction, is an essential
requirement. Additionally, you need to ensure that the lead screws and the linear axes are greased according to
the maintenance plan of the STEPCRAFT.
Now open the manual jog menu by moving the mouse pointer to the left side of the main screen:
Move the cursor to the arrow keys and place the machine carefully in the middle of the workspace of the system.
To increase the moving speed you can adjust the jog feed.
Jog feed 10% = 300 mm/s
Jog feed 100% = 3,000 mm/s
8
The 3D printer plugin is not ready to work because of the missing homing sequence (see later item 2.7):
2.6
VERIFICATION OF THE LINEAR AXES
Please refer to item 2.7 if you have already done the verification (see also the assembly manual and the
first steps manual).
NOTICE: The machine must be noiseless and needs to move without friction and tension in all linear axes.
NOTICE: If you have already levelled the machine you can skip this item and proceed with item 2.7.
For checking, please proceed as follows:
-
Place the machine on a level surface.
-
First loosen the screws of the gantry parts of the X-axis (see instructions 5.2 and 5.4), the rear (see
instruction 6.5) and the front (see instruction 8.10) of the Y-axis.
-
Move the Z-axis manually to an average height.
-
Move the X-axis manually to each end of the gantry and tighten the screws of each gantry part.
-
Now move the Y-axis towards the back and tighten the screws of the rear panel firmly.
-
Lastly proceed now towards the front and tighten the screws of the front panel.
NOTICE: If you do not reach the final position of an axis in this way, then you must check the smooth running of
linear axes and spindles. To do this, close the WinPC-NC / UCCNC or any other CNC control program and
unplug the machine from the electricity supply. The X- and Z- axis can then be moved by hand over the axis
connector (part 58). For movement of the Y-axis remove the tooth belt cover (part 75), and possibly also the tooth
belt (part 73), in order to check the axes individually.
2.7
HOMING
Before you can start to work, the machine has to be homed (pick-up the reference point or machine zero-point).
Press the “home all” button in the main screen:
The machine will start driving all axes now, beginning with the Z-axis, until it reaches the reference switch of each
axis. When the homing is completed, the machine (seen from the front) features (X) on the left, (Y) at the rear and
(Z) at the top.
9
At the same time, the reference for the machine zero point is initialized (above example for STEPCRAFT-2/300).
The X-axis and the Z-axis will be initialized with 0, the Y-axis with the possible traverse distance.
Notice: The actual machine zero point is (front view) left (X), front (Y), top (Z). Notice that the reference switch for
the Y-axis is at the rear but the machine zero point for the Y-axis is at the front. This explains why all axes except
the Y-axis will be set to zero after initialization.
The reference run is to be carried out regularly after turning on the machine and before starting to work.
Additionally the 3D printer plugin is ready to work (“Plugin is working!”):
3 WORK PREPARATION
For further implementing the first step instruction, you are in need of the following materials:
-
STEPCRAFT 3D print head
-
Filament with diameter of 1.75 mm
-
Print table, e.g. acrylic table
-
Pair of tweezers
3.1
FIXATION OF THE PRINT TABLE
First you place the offer worktop on the machine table, secondly the workpiece material. Attach the two plates
with the accompanying retainers from the STEPCRAFT to the machine table. The screws need to be tightened by
hand only:
10
3.2
IMPORTING THE PATTERN
Open the pattern file with the “Load File” button in the main screen. Navigate to the /Examples/03-3D print
directory of the UCCNC CD and open the file Stepcraft-Logo-Standard-Print.gco
The file consists of a 3D pattern of the STEPCRAFT logo. The workpiece has a size of 30 x 30 mm (approx. 1.25
inch x 1.25 inch).
NOTICE: The starting point for this pattern was originally set in the CAM program STEPCRAFT Repetier Host to
the middle of the workpiece. It is also common to set the starting point to the edge of the workpiece, for example
to the left front corner. Every time you import an already existing work file you have to make sure where the
starting point of the CNC code is.
11
3.3
DEFINITION OF WORKPIECE ZERO POINT (X, Y)
Do not turn the print head on.
Chuck the 3D print tool into the spindle. Lock the 3D print head into the tensioning system with an Allen key.
Beside the knowledge of the starting point of the CNC code you need to define the starting point on the work
sheet. This point is also called workpiece zero point. Highlight this point with an "X". Make sure that, when seen
from the front, there is sufficient travel available to the left and right and to the front and rear side (at least 40 50 mm in each direction).
Open the "jog" menu by moving your mouse pointer about the left screen side of the program and then drive the
machine manually to the point marked. Move the Z-axis to half maximum height.
Alternatively you can also use the cursor keys (left, right, top, down, picture up / down) of the keyboard to jog the
gantry.
Save these settings by clicking "Zero all" in the main screen.
12
The workpiece coordinates are then X = 0.000, Y = 0.000 and Z = 0.000. The yellow dot in the toolpath preview
marks the actual position of the machine and is located in the centre of the workpiece as expected.
NOTICE: If you do not see the yellow dot in the centre of the workpiece toolpath, repeat item 2.7 and 3.3.
3.4
PREPARATION OF THE 3D PRINT HEAD
Stay alert, watch what you are doing and use common sense when operating the 3D print
head. Do not use the 3D print head while you are tired and / or under the influence of drugs,
alcohol or medication. A moment of inattention while operating heated tools may result in serious
personal injury.
Use personal protective equipment. Protective equipment will reduce personal injuries.
Prior to first usage, read the operating instructions of your STEPCRAFT 3D print head
thoroughly and carefully, making sure you have understood everything.

Turn the adjustment screw carefully and as far
as it will go (clockwise) until it can no longer be
turned. Then, turn the adjustment screw half
turn to the left. Now the print roller is set
correctly.
7.
Push the filament supply back into the
housing.
8.
Connect the control unit of the 3D print head
with the power supply and the mainboard of
the STEPCRAFT 3D desktop system. Turn the
control unit of the printer on; set the
temperature to 190° C.
Picture
After the operating temperature is being
reached, start to exhaust the system. The
filament must be boosted with moderate
forward jogging of the 4th axis (max. speed
20%) until a clean thread is printed out.
9.
CAUTION: Hot!
Remove the thread, e.g. with a pair of
tweezers.
NOTICE: If the filament is already inserted into the 3D print head, only steps 8 and 9 apply.
3.5
DEFINITION OF WORKPIECE ZERO POINT (Z)
The workpiece zero point (Z) is the point where the end mill touches the surface of the workpiece. Jog carefully
with the nozzle of the 3D print head towards the print table.
14
Take a piece of paper, place it onto the print table and proceed slowly and manually in the Z-axis downwards
towards the print table. Move the paper back and forth with your fingers.
Once the nozzle touches the paper, save that point again as the workpiece zero point X / Y / Z by pressing “Zero
all”.
The 3D print head may not stay on the paper / the surface of the print table longer than 10
seconds! The tool has to been lifted as soon as possible. Risk of fire!
15
After this, move the Z-axis manually up to approx. 20 mm above the print table.
16
4 STARTING THE FIRST 3D PRINT PROCESS
Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool while you are tired and / or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious personal
injury.
Use personal protective equipment. Always wear eye protection. Protective equipment will
reduce personal injuries.
Prior to first usage, read the manual of your STEPCRAFT 3D print head thoroughly and
carefully, making sure you have understood everything.
Speed will be automatically controlled by UCCNC. Be aware that the temperature of the 3D print head is
controlled manually and you have to switch off the control unit after the job has been finished.
Now press the “cycle start” button.
The machine moves from the workpiece zero point X = 0.000 and Y = 0.000 to the start point of the first outline
down to Z = 0.300. The manufacturing starts.
Do not reach inside the working area of the 3D print head while it is in operation. Contact
with the moving parts during operation may result in poor build quality, equipment damage or
personal injury.
Do not leave the 3D print head unattended during operation. Use of 3D print head by persons
unfamiliar with these warnings and instructions may result in equipment or property damage and
personal injury.
After completing the work process, the system automatically moves to the workpiece zero point (X, Y) and to the
top Z-axis position. Turn off the 3D print head and move the gantry to the rear end of the desktop system.
17
Use personal protective equipment. The use of protective equipment such as heat resistant
gloves and safety glasses will reduce personal injuries.
Be aware of your body position when using hand tools to remove objects from the print
table. Sudden tool slip and improper body position during object removal from the print table may
result in personal injury.
Remove the workpiece carefully.
Congratulations! You have completed your first 3D workpiece with your STEPCRAFT.
