Frequently Asked Questions and Answers
- What is a Safety Charge Pump (SCHP)?
It is a watchdog. It is a feature in which the control software will send a pulse stream through a pin, as if it was moving an axis. Then a microcontroller on the breakout board will see that pulse stream and will know that the signals coming from the c...

You can find several wiring diagrams for different VFDs and Speed Controllers in the Product Download section of the C11G: https://www.cnc4pc.com/c11g-multifunction-cnc-board.html#pattachments. Please choose one that may match the VFD you have. You can ...
Read more - I have a Seig FC350BJ/110V spindle drive on a X2 Harbor Freight mill. I am interested in buying the C6 board to allow Mach3 control of the spindle. Do you have wiring diagrams and Mach 3 configuration notes on how I can use the board? Thanks
It is ideal to use a breakout board that has the spindle control circuit built-in and that uses a Safety Charge Pump. This will greatly simplify your wiring and using a Safety Charge Pump when wiring your system delegate starting your spindle to the...
Read more - I cannot get the green LED to enable on the breakout board
3 conditions must be met to get the enable LED: The board must be properly powered. Check the documentation on the board, as a misunderstanding on how it is powered is very possible. The board must be connected to a PC/Motion Controller which is c...

VFDs and motors have two way of operation, in the US we use CW and CCW, in the rest of the world, or INT (International) it is used START/STOP and DIRECTION. These settings can usually be adjusted VFD settings. The chances are that if you purchased the V...
Read more - I am look at your touch probe, will this work on a c11G board if yes please send information. Thanks
Yes, the probes can very easily be wired to the C11G. The probes ship with a female jack connector that can be connected to the terminals of the C11G. the C11G has a jumper to set the input to be set to pulled-up. If you have any issues ...
Read more - Do I have to have a USB/DB25 cable or can I use a DB25/DB25 cable without the USB connector? I am replacing a breakout board on a 3 axis router table. No extra features except for emergency stop. Using Mach3. Thanks. R. Barrett
The UC100 is what you are looking for: https://www.cnc4pc.com/uc100-usb-motion-controller.html It will work very well with any standard parallel port.
Read more - Do I need stepper motor drivers? or is this integrated on the board? I currently use the UC400 ETH and am looking to replace my control board.
C11G is a very good option to be used with the UC400ETH. But the C11G does not have built-in Stepper Drivers. You may want to check the C85 as it may be a better option if you need built-in Stepper Drivers: https://www.cnc4pc.com/multifunction-4-axis-d...
Read more - According to the manual, a 12/24v power supply is used for the proximity switches. Th e video on the C11G does not use an external power supply and the manual also shows a resistor being used (not in the video). Just a little confused.
To use voltages above +5vdc you use a limiting resistor, as the C11G can only take +5vdc signals. It is described in the manual. I am not sure what video you are referring to, but you are welcome to open a ticket and we will give you a hand with this:...
Read more - The Analog Output to the VFD is not stable
The issue is related to noise coming back from the analog input terminals on the VFD. They are supposed to be isolated, but sometimes noise finds a way. There are two ways of fixing that: - Use shielded cables for the analog and its ground and ground the...
Read more - What Window OS am I to used for motion control with this board?
The C11G requires you use a motion controller. If using Mach3, you can use the Parallel Port as a motion controller over Windows /32. We recommend using the UC100 or Ethernet Smooth Stepper on Win10/64.
Read more - can you use this to drive servo drives??
You could, but you could probably be better off using a C76 or C82 as they can connect to the servo fault and enable signals.
