Our Getting Started guide will walk you through the specifics of setting up your SmoothStepper. However, this documentation page contains a large amount of information that is not covered in the Getting Started guide. Any machine tool is potentially dangerous. Computer controlled machines are potentially more dangerous than manual ones.

Warp 9 Tech Design, Inc. It is your responsibility to ensure that you understand the implications of what you design and build and to comply with any legislation and codes of practice applicable to your country or state. Each of the 2 previous links provides a short video and documentation on how to install the respective pieces of software. It is outside the scope of this documentation page to explain the operation or configuration of CNC systems and Mach3 or Mach4 except for information that is specific to the SmoothStepper.

For information pertaining to the operation of Mach3 and Mach4 and CNC systems in general, there is a wealth of sources already available:. Installation of the Ethernet SmoothStepper is meant to follow the order of the sections on this documentation page. Please follow this sequence and you should have a successful installation. Please visit our Products Page for a detailed capabilities chart. Because it has a connector that conforms to the Parallel Port standard, it integrates seamlessly with most devices that the Parallel Port driver of Mach interfaces with.

Because it is a dedicated hardware device, it is capable of producing pulses at very high frequencies and with extremely low jitter compared to the Parallel Port driver and microcontroller-based solutions.

In addition, the SmoothStepper is able to run on any flavor of Windows, both bit and bit. Mach will run under bit or bit, but an external controller such as the SmoothStepper is needed for bit editions. The SmoothStepper was designed to be a parallel port replacement.

The terminal blocks provide a convenient method of connecting motor drivers, limit switches, etc. By converting electricity to light and back again, an electrical path for damaging voltages and currents is eliminated. The computer connects to the ESS via a standard inexpensive Ethernet cable. The cable may be shielded or unshielded. An advantage of Ethernet compared to USB is that the cable length may be as long as meters feet.

The maximum length for a USB cable is 5 meters, and that is pushing it in a noisy environment. Another advantage is that Ethernet uses transformers for coupling the data signals, which galvanically isolates the computer from the downstream electronics. This is a board that has one or more connectors that have a parallel port interface. Typically it is a pin header that is identical to the connector on the ESS, or a DB25 just like the parallel port of a computer.

This connection is usually made via a ribbon cable. An inexpensive alternative to a breakout board is to connect a ribbon cable to the ESS that has a pin header at one end, and no connector at the other.The FAQ Mach3 page may also be of some help to understand basic concepts. Please visit our Mach4 Getting Started Page. In the forum post you are writing, go down to the Attachments section, and click on Add File. Navigate to the profile you just saved, and select it. It should then appear to the left of the Add File button.

The best place is on the Mach Support website itself! Just before you cause the event to happen or just before you start the run, please press the 'Clear' button to get rid of any extraneous information in the log file.

After the event occurs, pleas press the save button to save the data, and then upload it to us if requested or relevant. If possible try to make the log as short and concise as possible I don't need 20 minutes worth of data if you can make it happen in 20 secondsbut also don't delete relevant information either.

What is really helpful is if you can say my problem X happened at this specific time what ever it happens to be in the log file. If you place mc. Same effect as 1 without installing the plugins.

This window may be useful during the initial setup of your machine, but I almost never go into it except during some rare troubleshooting. Some boxes may be checked, some boxes may not be checked, it depends on how your BOB is designed pull ups and pull downs on each inputand more importantly if you have something wired to an input and what it is doing.

If the box is checked, that means the input is active. If it is not checked, the input is not active. The boxes are updated whenever the ESS sees the pin actually change state from Active to Inactive or vice versa.

Open the Mach4 motor tuning and make sure everything is correct. It should be working, but why isn't it? Upon startup of Mach4, the last commanded speed is set to a default value of 0 RPM.

Here is an example of how to create a macro in Mach3but it is essentially the same here in Mach4, you just save it to this folder path instead. On a mill or router setup, this will usually be sufficient since you are running at hundreds or thousands of RPMs, and you are not relying on a precise RPM readings.

The exception to this would be if you were doing slow speed tapping. This is very useful for low RPM lathe threading, especially with heavier cuts. The additional pulses per rev will tell the SmoothStepper what the instantaneous RPM is, and it will adjust the Z and X axis motion to compensate and deliver a quality threading pass. Please read this page for more details regarding PID setup.

Open loop mode works well if you have a powerful spindle or the loading on the spindle does not slow it down significantly compared to when it is cutting air. However, if there are significant changes in spindle loading, that loading may slow down the speed of your spindle significantly; negatively affecting the quality of your cut or breaking tools. The Closed Loop method avoids this by looking at the reported spindle speed and adjusting the current PWM duty cycle value up or down so that the measured spindle speed will match the commanded spindle speed.

The Kp term you specify is the Proportional Gain, which is simply a constant correction term value multiplied by the error amount. In situations where the loading on your spindle changes significantly and quickly, the remaining Ki and Kd terms can increase your performance significantly. The Ki term you specify is the Integral Gain, which is a correction term that responds to size of the error over time.

The longer the error amount exists the larger the influence the Error Result Integral ERi term will have, and it can dominate the Error Result Proportional term quickly when configured properly.

The Error Result, Integral ERi is designed to minimize the error amount as quickly as possible to get you back to zero error although this can lead to overshooting.Plugins are expansion modules written for Mach3.

Mach4 has new features under development and has much more in terms of capabilities and flexibility - especially with lua scripts. However, the number one reason in our book is diagnostics, in Mach3 it is hard to determine what went wrong when something doesn't work.

In Mach4 the diagnostics log and the screen set messages make it much easier to understand what is going wrong. Mach should then be able to communicate with the ESS again.

If it can't, please make sure you are not running Norton, McAfee or other 3rd party firewalls, that may be blocking Mach3 from communicating with the ESS. Finally if it is still not working, please watch this video on how to use the SCU to reset your Windows Firewall to default and add Mach3 rules to it.

After each major step, try using your hardware to see if you set it up correctly. I have you exiting Mach3 often, since it will save the settings to the XML file, and it helps to prevent mistakes. You may ignore this message, which cannot be changed since Mach3 is legacy software that cannot be modified at this point. Just clear the History window, press Reset and continue on your way. Scroll down to EStop and place a green check in the Enabled column.

Assign it to the desired input pin. You may need to change Active Low depending on your hardware. Press OK to close that window.

Keep in mind that the picture you see below is for example only. You can do this to test and verify that the SmoothStepper is communicating with Mach, but you really need to make sure you assign it to your EStop button afterwards! Press the Red Reset button in the lower left corner of Mach3.

The flashing red border should be replaced by a solid green border if it is, Mach is communicating with your SmoothStepper. You can also look at the Mach3 screen set's Diagnostic tab and see if the Emergency signal turns on and off then you activate the EStop button.

Now assign the Axes that you will be using. For each axis you will use, click on the red X to change it to a green check mark. You may need to change Active Low for Dir and Step. If you use two motors to move the same axis, the A axis would typically be your first slave motor. Set the Port and Pin as appropriate for you hardware. We have a FAQ section here. How do you calculate your steps per unit? Click on X Axis on the right.

Set your Steps per unit, your Velocity and your Acceleration. Click on Y Axis on the right. Repeat for the remaining axes. To modify which axes are available, go back to the Motor Outputs step. Test to see if your motors will move by pressing the arrow keys on your keyboard. Calculate and set your Max Step Frequency, for each of your axes.

Set the Controller Frequency to 1 kHz. This will be a good starting point for most users. This will let you move your Axes around a little. Set the look ahead to or lines. If you get a "Run out of data" message, adjust your watchdog. Configure your constant velocity settings as needed.Hello Guest it is March 15,PM. Guest Login Register. Read times. Ken I've been wanting to start using a smoothstepper so that I can run windows 7 64 bit on my CNC machine but have some concerns about the features I may be losing if I make the switch from parallel port to Smoothstepper.

First, i'm limited to the USB version. My CNC hardware and PC hardware, all breakout boards, pc motherboards, stepper drivers, power supplies etc are all mounted in the same mining-rig enclosure, which is mounted to the side of the CNC enclosure.

The breakout board connects to the PC motherboard via headers, and the smoothstepper would also be mounted inside the enclosure and necessarily connect to the motherboards onboard USB3. I'm OCD about wiring neatness, having an Ethernet smoothstepper would mean a hole drilled into the enclosure, and a wire hanging out of the hole so it could be plugged into the back of the motherboard.

Such a thing would be like having a penis growing out of my forehead. It's mere existence would be intolerable, like a snake loose in the house, I couldn't stop thinking about it until it was gone. My biggest concern is the features I might lose switching to the smoothstepper.

First, closed loop PID control of the spindle motor. Currently, my 1. I really don't want to lose this. Also, i've read that I will lose backlash compensation. This isn't as big of a deal as my ballscrews have almost no backlash but I do occasionally, rightly or wrongly, use it to hit a tolerance when it's is a couple thousandths undersize or oversize. The ability to use speed override in the positive direction.

I've read that the smoothstepper won't allow feed override to increase the feed speed. Are my concerns realistic? Is there a way to actually control the spindle closed loop, use the feed override and backlash compensation with the smoothstepper? How does it cause these issues? For example, if Mach 3 is sensing rpm via the index signal, and modulating the pwm pulsewidth to adjust RPM, does the smoothstepper not communicate these instructions to the breakout board, or does the smoothstepper somehow prevent these calculations from taking place at all?

Hi, I use the ESS and it is much preferred, much lower latency and electrical noise immunity. The Mach3 plugin having been around for so many years is in most respects more advanced and complete than the Mach4 plugin. In addition to the extra port it has a bigger FPGA. The bigger FPGA allows greater support for different features.

The lack of THC support is due to the electrical interference of the plasma making a USB connection just too unreliable. The Ethernet connection is very much more reliable. My wife left with my best friend Ill consider what yove said. I have the USB smoothstepper installed and currently running a program to test it. Everything is running very well except as predicted, the spindle speed accuracy has suffered as it is completely open loop.

It is within 40rpm though. Everything else is great. Ill try cutting some metal in a few minutes to see how much it bogs down the bldc motor without a pid loop.The SmoothStepper does not have a PWM or analog output, so it cannot drive that style of motor driver. The SmoothStepper outputs 5V signals with currents limited to 24 or 32 mA, dependent on the selected output pin.

YES, tuning is of critical importance! Tuning will optimize your servo's PID loop parameters to work with the loads of your axes, along with your acceleration and velocity parameters, to get fast and smooth motion with minimum overshoot and minimum lag. Make sure that the acceleration and velocity parameters you set in Mach's Motor Tuning window are the same or slightly lower than the acceleration and velocity parameters you set in your Servo's configuration before tuning.

If Mach has higher values for these parameters, you may get rough and jerky movement. Mach's acceleration and velocity parameters can be significantly lower than the Servo's parameters, you just won't achieve your hardware's maximum potential.

Servos have a very distinct advantage over steppers at speed, however steppers enjoy a BIG advantage in torque over servos at low speed. Stepper motors have a tremendous amount of torque holding power at a standstill and lower speeds. For precision mill work, where you are producing a lot of cutting torque and need lots of positional holding power, steppers do a great job!

In this area, servos will need to be oversized in order to provide a comparable amount of torque as steppers at these speeds and loads. In Open Loop Control mode, every time the SmoothStepper sends a step pulse, the motor driver will advance the motor, without providing positional feedback to the motor driver.

The motor driver will assume that the motor successfully made that move. If the axis binds up, there was material blocking movement or cutting too aggressively into material the motor will stall and the motor driver will be unaware. Once a machine is set up properly, this is typically not a problem, however, it is a possibility.

In Closed Loop Control mode, the motor driver will record the incoming step pulses from the SmoothStepper and know what the motor's commanded position should be at all times. The motor's current position is measured constantly and fed back into the motor driver. The current position and the commanded are fed into a PID loop, and the motor driver will adjust the motor's actual position to correct for any missed or lost steps, while not lagging too far behind the commanded position or overshooting the commanded position.

The SmoothStepper can read the positional data in via encoder inputs, and will display the positional data, but you do not need to send the positional data back to the SmoothStepper in closed loop mode. Most Stepper motors are driven with an Open Loop control, although some stepper motors now come with closed loop controls. If you are considering going with closed loop steppers, it is usually worth spending a little more and go for servos with closed loop control.

Servo motors are closed loop systems. The downside is that the servo motor may lag slightly behind its commanded position, especially at high speeds. However, if your system is tuned properly, having closed loop servos is more of an advantage than a disadvantage. The Fault or Error output from a Servo driver can be connected to unused SmoothStepper inputs and assigned to unused limit switch signals.Everyday Wellness 10 Crucial Things You Should Always Have in Your Home Emergency Kit Store these necessities in a safe place for easy access when disaster strikes.

So They Become Professional Honey Makers. So They Decided to Do This. A song I use as a reference track all the time is I Should Have Known by Amie Mann.

It has so many of the sonic elements that I strive for.

It's a wonderful track. On the opposite side of the reference spectrum, is Neil Youngs Tonights the Night. Possibly my favorite album of all time. Very real and somewhat stark. It reminds me of the importance of honesty and the power of simple human emotion.

And thanks for all the tips and insight Warren, Much appreciated and utilized. Hi Sean, that is a fantastic reference track. One of my oldest friends is Jute Butcher, Jute is an outside broadcast engineer who was with the BBC for years (his brother is Matt Butcher long time Blur FOH Mixer), Jute has magic ears and he would always use that song as a reference!.
