1.1 You need Help?
You have chosen a kit.
If you have any concerns, we can also offer you the assembly of the components at
this point in time. Just send us an email with your request to: [email protected].
Everything else is then clarified.
1.2 Note
This kit was built and tested many times as a prototype before go to production. Only when
optimum quality is achieved in terms of function and operational safety, it is released for the
series.
In order to achieve a certain functional safety during the construction of the controller, the
entire structure was share down into two stages:
1. Stage I: 2.1 Assembly the components
2. Stage II: 3.0 Functional test
When soldering the components, make sure that they are soldered to the board (if not
indicated otherwise) without distance to the PCB.
All protruding connection wires are cut off directly above the solder.
Since this kit is sometimes very small or narrow spaced pads (solder danger), it is only
possible to solder here with a soldering iron with a small soldering tip. Solder carefully.
2.0 Soldering instructions
1. When soldering electronic circuits, never use Soldering water or soldering grease.
these contain acid, which destroys components and traces.
2. Use as soldering material only PB38SN60CU2 (lead 28%, tin 60%, copper 2%) with a
rosin core which also serves as a flux.
3. Use a small soldering iron with a maximum of 30 watts of power.
4. The soldering must be done quickly, too long soldering destroys the components by
excessive heat..
The maximum temperature is 250 °c for 5 seconds per pad.
5. The cleanliness of the soldering tip is essential for a good soldering result.
6. After each soldering, clean the soldering tip with a damp sponge or a silicone wiper.
7. After soldering, protruding connection wires are cut directly above the solder with a
side or flat cutter.
8. After the fitting, always check each circuit again to make sure that all components are
correctly inserted and poled. Also check whether connections or conductors with tin
were accidentally bridged. This can lead not only to malfunctions, but also to the
destruction of the components.
9. Please note that improper solder joints, wrong connections, incorrect operation and
assembly errors are outside our sphere of influence.
10. Be sure to observe the safety instructions under point 5.0!
2.1 Scope of delivery and required tool
2.1.1 Scope of delivery:
● 5 pieces optocoupler with 4 connections
● 1 piece optocoupler 16 connections
● 1 piece DC-DC Converter, set to +5V
● 1 piece Precision Potentiometers
● 2 pieces 15-pin female socket
● 4 pieces one pole pin bar (Possibly pre-assembled)
● 1 piece of LED ø3mm
● 12 pieces screw terminals, dual pole
● 2 pieces Screw Terminals, three pole
● 1 piece Capacitor
● 1 piece 5V Arduino Nano V 3
● 1 piece professional produced PCB with pre-installed SMD components
2.1.2 Required Tools:
● Soldering iron (30 watts)
● Soldering Tin ø0.5mm (e.g. Pb38Sn60Cu2) or equivalent.
● Side- or flat Cutter
● Well would also be a breadboard
2.2 Assembly of components
All parts are marked on the top of the board.
Now proceed as follows:
1. Insert the two 15-pin socket on the Arduino nano
Figure 2.2.1
2. Place all Optocoupler and the 16-legged optocoupler as in
Figure 2.2.2 shown on the board and solder it.
Figure 2.2.2
3. Now place all screw terminals as shown in Figure 2.2.3 on the board and solder them.
Figure 2.2.3
4. Now place the LED on the PCB, attention check the polarity,
5. the longer leg of the LED is the anode (+) and solder it.
Figure 2.2.4
6. Now place the capacitor on the PCB, look the correct polarity, and solder it.
Figure 2.2.5
7. Now plug the Arduino Nano with the socket onto the board and solder it.
After soldering, please remove the Nano from the PCB!
Figure 2.2.6
8. Place the precision potentiometer on the PCB as shown in Figure 2.2.7 and solder it.
Figure 2.2.7
9. Now solder the four one pin strips at the corner on the DC-DC converter. If you have a
breadboard, you can do this to help you place the pins straight. If the solder are
already soldered, you can proceed to step 9.
Figure 2.2.8
10. Now place the DC-DC converter as shown in Figure 2.2.9 on the PCB,
11. Check the right polarity (inputs and output) and solder them.
Figure 2.2.9
12. Shorten the protruding legs of the LED, capacitor,precision potentiometer
and DC-DC converter.
13. Perform a conscientious visual check and watch for any short circuits!
3.0 Functional test
Estlcam: Version: 10,xxx
CNC Motion Controller: AC-CNC2017-2S (REV03)
3.1 Connecting of CNC Motion Controller
Connecting the control card:
Now insert the Arduino Nano into the CNC Motion Controller.
Supply CNC Motion Controller with 24VDC (screw terminal "24V in").
In attention check the correct polarity.
Connect the CNC Motion Controller to the computer using a USB cable.
3.2 Setting the EstlCam Software
Settings in Estlcam:
Open Estlcam and got to „Setup->CNC Controller“
Tap Basic settings:
● Preset: nothing
● USB/COM port: YOUR COM Port
● Pin layout: Estlcam
Figure 3.2.1
Tap Spindle (if you use a HF Spindle):
● Lower RPM limit: 6000 rpm
● Upper RPM limit: 2400 rpm
Figure 3.2.2
Please refer the datasheet (from spindle manufacturer) of your milling spindle
for the exact connections and speed limits.
Tap Inputs:
End-switch 1, 2, 3;Probe input (SE); Error input(FE)
● Enabled: on
● Inverted: on
● Pull up 5V: off
See Figure 3.5.1 below.
3.3 Programm the CNC Motion Controller
Programming the CNC motion controller card with the help of the Estlcam software
Tap basic settings:
Press the Button: „Programm Arduino“
3.4 Preparation
Tools:
You need a voltage meter and a through tester or a corresponding instrument.
You also need a short piece of wire with 3mm naked ends
as a wire bridge, and a small screwdriver.
3.5 Inputs and outputs
Test the inputs (SE, FE, E1, E2, E3):
Open Estlcam and got to „Setup->CNC Controller->Inputs“
Figure 3.5.1
At the screw terminals, use the wire to bridge the limit switch 1, 2, 3; Sensor input and
error input (E1, E2, E3, SE, FE).
Figure 3.5.2
If all the inputs are working, this was shown as "triggered".
If problems occur, program the controller new, check all solder, check the installation
direction of the Optocoupler.
Measure if the screw terminals are connected to the + 5V.
