where can I find wiring instructions for the Mach3 USB controller?

To use a touch plate on any controller, all you need is a conductive flat material with a known thickness and some wire and alligator clips. Solder a wire to the touch plate and connect the other end of the wire to the free input terminal of the controller. Connect a wire with an alligator clip to the ground of the controller (on the Mach3 USB controller, this ground is the DCM terminal, or the digital gnd on the 24VDC power supply). Connect the alligator clip to the end mill.

You can either use a script to serve as the probe, or you can use the ref all home button and setup the touch plate as a home switch.

The best way to determine how to control your VFD using Mach4 is to read the MAch4 manual found here:
http://www.machsupport.com/wp-content/uploads/2014/05/Mach4%20Installation%20Manual.pdf

You will find that there a a few ways to control the spindle/VFD on your CNC machine or CNC Router.
- The first and easiest is to have your VFD's power controlled by a relay. This will allow your spindle to have on/off control through Mach4 with an output pin.
- The second is to have a controller output a DAC voltage between 0-10 volts to control speed on the VFD/Spindle. There is a termial on the VFD to receive this signal line. The controller will also have an output that outputs a high or low and that can control the on/off on the VFD.
- The third, and more difficult of the three methods is to use a USB to Serial adapter (USB to USART or RS-485). The Computer plugs into the adapter using a USB cable and the adapter uses the RX/TX to connect to the VFD's terminals for communication. This will provide a great amount of control. Mach4 will need a plug-in to make this option work.

WTF!! It says right on your utube page free plans available. I'll paste it from Utube right here.(DIY CNC Router for Under $900 - Free Plans Available) Very misleading, I spent a lot of time looking for this stuff and am lucky I found this because apparently none of its available for free. Very misleading, dishonest sales tactics. I'm sure you've made money conning honest people out of there money but your not gonna get shit from me.

I have not tried using the handwheel inputs for anything other than for handwheel operation. I haven't had success using a THC with the Mach3 USB controller. The pokeys57CNC controller is a better solution for THC (torch height controller) and plasma cutter use.

[575] can the handwheel inputs be used for thc

You can use two MGPs (bare MPGs) to provide independent axis control. The handwheel input on this controller contains discrete inputs for the X, Y, Z, and A axes. These inputs can receive a pulse to move their axis. For instance, you can connect an MPG to the X-axis pin and the wheel will move the X-axis only.

Of course, if you have a traditional pendant, you can move any axis independently from only a single wheel with a switch that selects the axis you wish to move.

If you purchased the spindle from us, you should have received a little booklet that shows all of the program settings. If you did not receive that booklet, please call us so we can send you this booklet.

If you have the booklet, please let us know specifically what setting you would like to set and we can help.

Yes, this CNC controller can be used with closed-loop stepper drivers and motors. The loop for control and feedback is between the driver and the motor. The closed-loop driver receives step and direction signals, which this controller will output which furnishes the driver with the necessary signals to move the motor. Additionally, the closed-loop driver can output a fault signal to this controller through the controller's input terminals in case the motor should encounter a situation that prevents the motor from moving so the CNC can shut down.

The pulse stream is output directly from the onboard microcontroller on the Mach3 USB controller, so there is no need for a safety charge pump from the computer to the controller. Parallel port breakout boards were connected to the computer via GPIO pins (General Purpose Input/Output) and each pin dedicated to the step pulse would be output directly from those pins. In that case, a safety charge pump was needed.

Yes, the Mach3 USB controller can work with the Gecko G540 drives.

Here are the connections you will need from the Mach3 USB controller to the G540:
XP terminal to Pin 2 of the DB25 LPT connector
XD terminal to Pin 3 of the DB25 LPT connector
YP terminal to Pin 4 of the DB25 LPT connector
YD terminal to Pin 5 of the DB25 LPT connector
ZP terminal to Pin 6 of the DB25 LPT connector
ZD terminal to Pin 7 of the DB25 LPT connector
Any pins from 18 through 25 can be connected to the GND terminals next to the XP terminal.

Pins 10 through 13 can be connected to IN1, IN2, IN3, and IN4.

I have had no success with this controller paired with a THC

I would recommend using our 5.6 amp driver as a replacement for the TX14207 driver. Apparently, those drivers are found in the 6040 CNC routers and will not contain documentation since it is typically sold as a part of a greater assembly. Here is the link to the recommended driver:

I was looking for a MYJG80W power supply but I see you may not have the 220 volt version. Do you have these as yet and if not what can you advise on availability or where I may find one...Thanks

In theory, utilizing a 5V reference in the 10V terminal of the Mach3 USB controller should yield functional results, although I haven't personally tested this configuration. If you possess an oscilloscope, you can monitor the PWM signal to verify whether the AVI output achieves a peak 5V PWM square wave.
