If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

You can use one of the terminals on the input side of the breakout board to connect the e-stop switch.

WHICH WIRES ARE CONNECTED TO THE EMERGENCY STOP BUTTON

The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

If you are interested in the USB breakout board, you will need to get an independent relay board.

Are you using shielded wire? If so, take the shield to ground. If there are any other wires in the cable that is not being used, ground those as well. The customer can also try moving the cables as far away as possible from the motor wires and motors.

Do you have instructions how to mount the AWC708 DSP on the blackTooth?

I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

No, you should not have received two parallel breakout boards in your CNC kit. You can return the extra item using standard shipping with COD. Our apologies for the confusion and the inconvenience.

PROBLEM WITH LIMIT SWITCHES TRIGGERING

BYCNC Response:
This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

User Response:
I am using the cnc planet software for your USB board. Are the limit configurations in this software?

BYCNC Response:
Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

http://buildyourcnc.com/PrimeronHomingandLimitSwitches.aspx
There is a pin setting in Mach3 that says how to react to the inputs from the switches. Your setting is probably wrong as the trigger happens immediately.

You may want to think about shielded wire and/or a resistor on each limit switch line. If there are stray wires, connect them to ground. Additionally, the shield from the shielded cable insulation should alse connected to ground at both ends.
Try upping the Debounce interval in Mach3. You have to adjust the debounce interval. You go to config,general config, and it is in the top right corner. I set mine to 100 and it seems to work well.

Hey - the model number on the laser controller is

Additional Information:
Do you need any additional information here? I really want to get going on it this weekend!

Additional Information:
Sorry about that. If you are referring to the CN1 and CN2 connector, I don't believe it is needed if it didn't come with the connector. The components that we send to the customer is the same package that is sent from the manufacturer of the product. I would try connecting it to the CN1 connector of both units and test the interface (control panel).

Additional Information:
The manual for the AWC 708 shows the two ports CN1 and CN2 connected, but that may just be for thorough documentation if the CN2 is needed for some reason. Do you have a copy of the manual or know where to find it? If not, I will put the document link here.

WHAT ARE THE OUTPUT INVERTER (VFD) CONNECTIONS TO SPINDLE?

VFD settings........
1) To program the VFD, wire it up, plug it in. It takes several seconds to come to life.

2) Push the PRGM button to enter programing mode.

3 )Push the SET button. The display will read PD000.

4) If you push the SET button again, it will display the present setting of PD000.

5 )By pushing the up or down arrows, you can change the setting to whatever it needs to be. (This is just an example. PD000 needs no changes)

6)Push the SET button again to lock in the setting of PD000 and advance to the next number, in this case, PD001.

7) Push the SET button and it will display the present setting of PD001. Again, use the up and down arrows as necessary to set PD001, then push SET again to lock it in.

Note: You can also scroll through the PD numbers with the up and down arrows.

8) make all settings this way.

9) by pushing the SET button you can scroll through the settings. First push of SET moves to the next number, second push displays it's setting, third push moves to the next PD number.

Note- If you take too long, it will leave the programing mode on it's own. If it does, just push PRGM again to return to programing mode. Then press SET and continue what you were doing.

10) Start with PD013. Set it to 1, which returns the settings to the factory settings.

11) Then set PD005 to 400, PD004 to 400, and PD003 to 400 IN THAT ORDER.

12) Then set the following: PD041=8, PD144=3000

13) Set PD209=50

That's it for the programing. You should get 24000RPM when you push RUN.
