Here are some commonly encountered problems due to incorrect power supply choices: Some breakout boards also have this feature, which enables one of the two boards to supply power to the other. Using a poorly regulated power supply: Another possible solution is to use debounced or filtered inputs in the SmoothStepper setting inside Mach on your EStop, home and limit switch inputs. 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. As other devices are added that also use 5V, you increase the total current draw. If the environment is too hot, just cool down the environment and the ESS will be fine.

There are several styles of Parallel Ribbon cables availabledepending on your needs. Mach interprets a G-Code file that you supply to it, and converts each G-Code movement into low-level commands. Please enter a number less than or equal to This mode can only happen when the small plastic jumper shorting out both of the BootP pins JP1.

Here is a drawing showing the board dimensions, mounting hole locations, and the locations of the connectors: This can be a very difficult issue to troubleshoot, since most of the time it will work fine. Suppling other 5V devices with your power supply: The external circuitry should only be reading this pin’s value.

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. If the pin has no external circuitry connected to it, it will be pulled high. Mach 3 Setup Documentation: The noise can cause weird glitches, random crashes, or just make the program halt running. The SmoothStepper was designed to be a parallel port replacement. Applying an external 5V to the pin will just assist the pull up resistor.

Since the SmoothStepper outputs 5V signals with currents limited to 24 or 32 mAyou will need a motor driver between the SmoothStepper and the motor itself.

smoothstelper This will set your computer up to talk to the ESS, and test communications. This is an important status LED. When in normal operating mode BOOTP jumper removed connected to Mach it will blink multiple times per second, or appear to be on almost solid.

You really want to try and use a power supply that will stay between 4. Please read this link for our smootnstepper article on Safety Information.


The computer connects to the ESS via a standard inexpensive Ethernet cable. These output pins are rated to deliver 0V to 5V, but may go as high as 5. We also know of cases where antivirus smoothstepperr anti-malware software have caused problems. We also recommend that you set Windows Update to notify you that there are updates available instead of automatically installing them on its own.

If you have at least a dual core i3 processor or AMD equivalentyour computer smoothstepepr perform well. Never go negative or exceed 5.

Your external circuit can have the capability to sink much more than that, but 2mA is the recommended minimum. For archival purposes we have the original manual below, but it is to be considered outdated and therefore deprecated. The only way to fix this is to run the Configurator and give it an IP address again.

In addition, the SmoothStepper is able to run on any flavor of Windows, both bit and bit.

When the ESS is in this mode, it cannot accept a new connection from Mach. Other offers may also be available. If you hook a voltmeter between the two you would measure a voltage if the two were not the same.
