Yes, you can use 12VDC for the MAch3 USB controller at the 24V and DCM terminals. I have not tested using 12VDC in conjunction with the ACM and AVI terminals (PWM output) to control the spindle speed. PWM typically requires a reference voltage (from the VFD) and it's own voltage to produce the PWM signal. I am not sure if 12VDC is sufficient for the PWM. I have tested the inputs with 12VDC and they work fine.

[575] does the 24VDC input actually need 24 VDC if only using the input for homing switches? Can you use 12 VDC? and would it be damaged with a higher voltage than 24 VDC?

Yes, you can use a conductive metal to serve as a zeroing block for the Z axis. All you need to do is connect the block (conductive metal) to one of the 4 inputs on the controller. The end mill must be connected to the DCM terminal (the GND of the 24V power supply) of the controller. In the inputs dialog box (config-ports and pins-inputs). Under the probe line, enter port 3 and the pin used for the block.

[575] Hi can I use a zeroing block with mock three interface board and do you have one I can purchase and directions on how to set up

If you already have a Mach3 license, you don't need to purchase another one. The license is connected to you rather than the computer. Mach4 is licensed to the computer, but you are able to have multiple computers for each license, and can be switched from one computer to another.

If you purchased the license from me, you can call (make sure to leave a voicemail), or email to get a re-issued license.

[575] I have an older CNC (2018) which has been working fine. The Windows 7 PC crashed and I am trying to get operational again using a windows 10 machine. I will have to buy a new license for the Mach 3 so will need to get the interface board I have to talk to MAch 3. Can I get just the disc or is there a place I can download what I need?

Same issue here -- TTL output from the AWC708C never seems to be pulled low. Still troubleshooting.

Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals. It's ok to add more limit switches with the home switches, but each home should be on independent inputs. For example, connect home X and any other limit switch to IN1, connect home Y and any other limit switch to IN2, and so on. This will allow you to properly use the "ref all home" button in Mach3.

Additional Information:


Additional Information:
In the instructions (diagram 1) you show all the home switches connected in parallel? But here you say they need to each have their own inputs. "You will want to connect the homing switches (which may also serve as your near limit switches) to different input terminals." I dont see how the second and third axis can go home if the first axis has already closed the parallel circuit unless they back off a bit until the switch opens up again before the next axis goes to home? My machine has no limit switches so I assume they are home switches.

[575] I have finally got my limit switches wired and working - thank you. Can they also used as homing switches and if so it it just a question of looping the two inputs on the board i.e. the limit and home terminals IN2 to IN3

Yes, the Mach3 USB controller will work with the latest Windows version and in 64-bit mode. The 32-bit mode is only relevant for using the parallel port driver if you are using a parallel port breakout board. Since this controller is connected via a USB cable, the 64-bit state will work fine.

[575] I have a 64 bit Windows 11 laptop. Will this interface board work with this? If not is there an option you can suggest.

This controller does not have an encoder input to determine the speed of a lathe spindle. The Pokeys57CNC does have an available encoder input.

with parallel port controllers, you have the ability to jog using two axes at the same time, but with USB controllers, this is not possible.

[575] Hi, I recently purchased this board and everything seems to be fine! But I am not being able to jog two axis at same time as I used to do on my older board. Did I do something wrong?

Make sure that the spindle motor output pin is not interfering with the signal. Go to config -> ports and pins -> motor outputs, at the bottom of the table, there will be a line for spindle. Make sure that spindle line item is disabled.

Additional Information:
I disabled the spindle port and I am still only able to activate port 3 and get 24v and even there when I enter m5 the voltage bounces all over the place. The other outputs read all over the place whether they have been designated as the spindle on the spindle settings tab

I tried wiring a relay to each of the outputs and only out3 was able to activate the relay

[575] I connected this to 24v power supply and only out3 will show 24v when activated the other 3 read 300+v whether activated or not

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

I would not recommend slaving an axis using the method of taking an additional axis from the USB interface. Instead, wire both drivers to a single axis on the USB interface. This will insure perfect signal output to both drivers. If you requre the motors to spin in opposite directions, simply wire one of the motors to the driver reversing the coil A and B connections, or use a hex inverter (https://www.buildyourcnc.com/tutorials/Tutorial-Two-Motors-Spinning-Oppositely-On-Single-Axis).

I purchased a USB Breakout board, motors and drivers, paid for CNC USB Controller Software and I CAN NOT "Slave" an axis, but there is an option to do that. The moment I connect USB Breakout Board "Slave" option becomes shaded and I can no longer select it (becomes not functional). What is going on? Need help asap. Thanks

I AM INTERESTED IN THE 3 AXIS COMBO USB OPTION. NOTICE YOU ENDORSE PLANET-CNC FOR USE WITH THIS BUT WILL MACH3 INTERFACE WELL BEAK OUT BOARD?

The output current for the Mach3 USB Interface Board is 50mA. These outputs are generally not designed to handle heavy loads like Spindle Governor Relays (SGRs).

If your SGR requires a hefty current. Attempting to directly switch it using just the Mach3 USB Interface Board would not be a good idea. In that case, using your existing C36 rev1.1 board as an intermediary is the way to go. That board can handle higher currents and will act as a buffer, ensuring that the Mach3 USB Interface Board doesn't get overwhelmed.

[575] How much current can the outputs handle? I want to know if I can directly switch my SGR or if I have to go through the existing C36 rev1.1 board first.

The Mach3 USB controller will work with M3/M4/M5 or M7/M8/M9 combinations. M10/M11 is not available with the controller.

[575] does the mach3 usb interface board support the M11/M10 command set?

I do not recommend using the Mach3 USB controller to be used with a torch height controller. There are only 4 inputs on the Mach3 USB controller. We have tried to interface a Proma THC to this board without success; however, we did not exhaust all possibilities.

I would recommend the Pokeys57CNC controller to connect the Proma THC as I have interfaced these two before and they work well together.

[575] Hello. Does this USB interface board thc? I have the proma 150.

If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

The CW terminal is wired to the direction terminal on the 8825 step driver.
The GND terminal connects to the GND on the 8825 step driver

The 5V connector on the driver simply powers the logic side of the chip and needs to connect to VCC pin on the keyboard jog.
