The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

I have your Mach3 usb interface board and am interested in the relay board to turn plasma torch on/off. I have a different relay board that doesn't work, it needs 0/5v from output pin to trigger and the usb board doesn't put out 5 volts. Does this relay board need 5v on output or will work fine with this usb controller?

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

I HAVE A 2.2KW WATER COOLED SPINDLE WITH YL620-H VFD. THE VFD USES P#-## PROGRAM FORMAT. BELIEVE ALL CORRECT SETTINGS SETUP BUT WHEN TURN UNIT ON, IT SPINS AT ABOUT 200-300 RPM REGARDLESS OF WHAT FREQUENCY CHOOSE. DO YOU PARAMETERS IN THIS FORMAT FOR UNIT? THANK YOUR HELP. HUIBERT MEES

Do you have an oscilloscope? You will be able to see the PWM signal and determine if the output is correct. Make sure that you are using the 10V from the VFD as the voltage reference for the 10V terminal on the Mach3 USB controller. The 10V terminal is an input, not an output on the Mach3 USB controller. The 10V is the top voltage signal level that the Mach3 USB controller uses for the PWM signals 100% duty cycle.

[575] I have the wiring and programming and parameters set the same way that you do in the spindle speed control and outputs videos, I can start and stop the spindle with mach3 but can't seem to control the speed. Can you think of solutions?

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

[77] Hello. I’m interested in buying a water cooled spindle and VFD. I have an Avid Pro CNC and would love to control it using Mach 4 but I keep hearing it’s difficult to integrate. Also, is the water pump 120 or 240? I’d love any advice etc. eBay is a web of confusion with all of the options. Thank you.

Our spindle VFD's, have a multitude of different connectors that can be used for different operations. There is a manual that comes with each VFD, and you can refer to page 11 for different functions and descriptions.

We currently have a PWM, working with our machine, however it is connected via USB, and setup through Mach 3.
Also if you may have misplaced or lost the manual here is a link to the pdf:

It is likely that if your Spindle's collet is ER11 specification than other size ER11 collets will work with your spindle.

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

I also place the controller very close to the drivers (on the back of the gantry). All of the cables are shielded. The only long cables are the mains power cables and the USB cable. The USB cable is shielded and contains active repeaters.

There is no problem putting all of the electronics in a box and using long cables to the motors. This is the way I did it for a very long time.

Great site. I saw your videos of wiring the Mach3 USB controller. You place the drivers next to the Steppers. This means that you have very long leads to the USB Board? What about the placement of the controlling PC? Is it a problem to have the USB board, PSUs and Drivers in a control box and long leads to the steppers? Thank you.

Yes, the Mach3 USB board has two terminals that require 24V connection. Most VFDs have a 24V output that can be used to power this part of the Mach3 USB board.

The V+ and V- on the Mach3 USB is not absolutely necessary to operate the CNC machine/router. The V+ and V- of the Mach3 USB board powers the outputs, inputs, and spindle's speed and control.

Here is the Mach3 USB link for more information:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

The new YL600 VFD we have in stock may not have this 24V output. There is a 12V terminal, but I have not tested that terminal if it outputs 12V, or if it is a 12V input. If you are only conecting limit switches to the Mach3 USB and need to power that portion, 12V will be sufficient.

I will delve into these aspects in far more detail on video.

Thanks and Merry Christmas to you as well!

Hey Guys, I have a brand new redleaf and 5x. In the final stages of wiring and wondering a few things. Can I connect the Mach3 USB board V+ V- to my frequency inverter (type YL600-2s-2k20)? If so where? Will your upcoming (part 2)video deal with this as well as final connections for limit switches and stop button? Merry Christmas!

Do you have the Pokeys57CNC connected to a 24V external power supply?

Additional Information:
Yes, a 24V external power supply with the jumper positioned. I'm using the ethernet port so the 24v is the only source of power. I plan to measure the amp draw when I have a chance to see how much the vfd is drawing on the analog out.

Additional Information:
Further information. The resistance across the terminals on the vfd is 22k ohms. With an independent 0-10v current source I can run the spindle from 20 to 400 Hz. The PokeysCNC only gets to 3.8v with the vfd attached (and the vfd is at 150 Hz) compared to 10v when the vfd is not attached. The power to the PokeysCNC is steady at 24.18 V, so I'm not maxing out the power supply. Still looking for thoughts on what might be going on?

Additional Information:
And the other thing - The measured amperage is 0.17 mA for the 0-10 V signal (which makes perfect sense for 3.7 V and 22k Ohms).

Additional Information:
Just to bring finality to this issue - I added a 2.2 microfarad capacitor across the 0-10V input terminal (from signal to ground). This solved the issue. Evidently, it was an electrical noise issue.

Click the link to add information to this solution:
My pokeysCNC board creates and analog signal of 0-10V for 0 to 24000 spindle rpm just like it should from Mach3. However, when the spindle is on, the voltage only gets to about 3.8V for 24000 rpm. It seems like the vfd is drawing more current than the pokeyscnc analog output can produce. It there an easy solution to this problem?

Many shielded cables come in various materials and designs, so having one with a copper mesh covering the inner insulator wire is no problem. We currently use a extension cord found locally at a hardware store and include one 18G wire for ground. So a specific shielded cable is not a required, unless being used next to specific and sensitive electronics that are extremely sensitive to noise and voltage interference than a shielded cable is required.

Thanks

According to the supplier of the 2.2 kW spindle, the safest operating speed for the spindle is 6000 RPM. The supplier also stated that theoretically, the spindle can operate from 0 to 24,000 RPM. I am continuing a dialog with the supplier to delve deeper into understanding the configurations and ramifications of such configurations for operations outside of the safe boundaries into the "theoretical" ranges.

Fusion 360 is a program that allows you to design in a parametric 3 dimensional environment and also provides a great CAM toolset. Fusion 360 will produce the gcode with the CAM capabilities. The gcode is used to move the machine in various ways in order to mill the material; however, software is needed to interpret this gcode and cause the machine to move according to the gcode instructions. This is called control software. So Fusion is CAD/CAM, and you still need "control". Mach3 is one example of control software for milling and is highly recommended.

Install Mach3 onto the computer that will connect to the redFly(CNC electronics), then configure the Mach3 parameters for the machine (motor tuning, plug-ins, inputs/output, etc.). Home the machine, load the gcode into Mach3 and the machine will move according to the gcode.

A word of caution, since you are new to CNC machines, make sure you familiar yourself with the machine and the movements of the machine specific to how the gcode is arranged with respect to the coordinates of the machine. Try with very simple gcode until you get a very good understanding of how the machine will move.

Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?
