The parallel breakout board has the db25 connector for data and the USB connector for power. Connect the USB from the computer to the parallel breakout board so the breakout board will have 5V of power coming from the computer. The db25 connector (connector with the 25 pins) receive data signals for each pin from 1 to 17 and have respective numbered screw terminals, some for input and some for output (18 to 25 are gnd pins).

On this page, there is a datasheet that explains the connection schemes for the limit switches on step 1 of the instructions. The datasheet explains single and multiple switch configurations and parallel/serial connections schemes for the NO/NC (Normally Open/Normally Closed states).

If there is further information you need, please reply on this FAQ.

Please provide detailed instructions on how to connect limit switches to CNC USB BOARD. I can not find instructions anywhere. I am new to cnc world and really need help. Thanks

When did you purchased the VFD and spindle? We only started this after the date of the instagram post that offered this added service.

Additional Information:
I purchased it July 16, 2020 however due to all the 2020 issues, I'm just now completing my CNC and hooking up the VFD and Spindle.

Additional Information:
The service started on Sept 23, 2020. Your order was prior to that.

The soldering is straightforward. If you wish to have me provide this extra service, feel free to send the unit back with the cable and I will solder the cable and do the parameter check and test the VFD and spindle.

Additional Information:
When I purchased my VFD and Spindle, I forgot to purchase the wire for the spindle. I had an electrician run a 220 line and hook up the VFD. But I don't have the wire for the spindle. I'd like to get the one you recommend and just pay you for another connector and the soldering.

Additional Information:
Can I purchase the one you spindle wire you recommend and just pay you for another connector and the soldering.

You state "If you purchase cabling, we will solder the cable to the spindle and connect the cable to the VFD." I didn't see that when I purchased my spindle and vfd. If I place an order for the wire and another female adapter, will you please solder the connector to the wire?

Hey, sorry I just found the wiring diagram and see that #4 is disabled. My bad. Thanks.

I just purchased some wire for my 2.2 spindle as per your recommendation it's 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections. However, it's a three wire (black, white and Ground). Which numbers on the female pin connector do I connect the wires to. Cheers.

Hi, wanted to ask regarding a total length of the connector: "4 Pin Round Female Connector", and not only the screwing. It is very important for my company's application. Thanks a lot!

From the USB controller, the CP+ and CW+ are connected to the 5V terminal. The CP- is connected to the CP terminal of the driver and the CW- is connected to the CW terminal of the driver.

Connecting the limit switches on the redLeaf use the input pins on the parallel breakout board. Here is a link to the wiring diagram for that parallel breakout board.

https://buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/

The connection is simple. Just create a circuit from ground to the pin. When the pin is engaged, the circuit is closed (using normally open on the switch). Use mach3's autoset to automatically set the pin for the limit or home setting.

Do you guys have any videos showing how to connect limit switches to a redleaf? If not, could you please make one? I looked at the diagrams on the limit switch page but I don't understand them.

Yes, the header on the black LED panel used on the blackTooth uses the 2P sil housing into which two crimp pins will be inserted. The crimp pins will need to be crimped onto the ends of the ethernet cable wires.

Additional Information:

Click the link to add information to this solution:
The online Blacktooth assembly instructions in step 16 show how to connect the LED headers to strands of ethernet wires. The terminal used to connect to the header is shown in the picture, but it does not state what the part number is. Is the connector to be used part number 20170 labeled "Two pin 2P SIL Housing"?

When the z axis is going down, the laser turns on. When the z axis is going up, it turns off. The z axis directions is only a signal that is either 5v or 0v. That determines the direction. In vectric, you will need to set your machining operations with a very very small depth so the time it takes to get to its final depth is a very short time.

AM NOT SURE HOW TO SET THE Z AXIS TURN ON/OFF LASER WHEN CREATE CODE. KNOW THAT ITS TYPICALLY Z-AXIS MOVEMENT DOES THIS - BUT YOU DONT SHOW ANYTHING HOOKED UP IN PLACE OF AXIS.

The parallel breakout board contains a usb connector, but is only used for power. The USB interface board (sold here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout) does not use Mach3, rather it uses the planet-cnc software.

I am trying to connect my pockeys57cnc usb controller to my mach 3 software. I am totally lost on how to configure it all. Any help?

1, 2, and 3 will be used. They connect to the U, V and W connections on the VFD. I would actually use a shielded cable as this cable is used with motor coils and will definitely send off EMF. Connect the shield to the earth ground terminal in the VFD.

If the spindle spins in the wrong direction than expected, just swap two of the U, V, W wires on the VFD. It doesn't matter which two of the three wires.

If the motor has 8 wires, you will need to wire the stepper motor in bipolar parallel. This motor (425 oz-in) is wired as follows:

Red and Blue wires to A+ on driver
Yellow and Black wires to A- on driver
White and Brown wires to B+ on driver
Orange and Green wires to B- on driver
