Smooth Stepper - Ethernet

Ethernet to Triple Parallel Port (LPT) Adaptor

SmoothStepper Circuit Board

Power

The Ethernet SmoothStepper requires an external 5V DC power supply.
The power can be supplied via the green power-in terminal block or via pin 26 of any of the Port headers.
Please make sure your polarity is correct BEFORE you turn the power on!

 

The Ethernet Cable

You will not need a special Ethernet cable.  A crossover or straight cable will work fine.  The cable may be shielded or not.  Since cables are so inexpensive, it is better to use a shielded CAT6 cable, but an unshielded CAT5 cable will also work fine.  The SmoothStepper may be connected to an Ethernet switch or you may directly connect it to the Ethernet port of the PC.  It is recommend that the SmoothStepper be on its own private network, but it may work OK with light Internet traffic on the same net.  If your computer has only one Ethernet port, you may want to purchase a USB to Ethernet adapter and run the Internet on the USB port.  That way all of the machine control will be on its own private network.

Mach3

Make a copy of your current XML (profile) file, just in case something goes wrong.  The XML files are located in the c:\Mach3 directory and have extensions ending in ".xml".  If you are launching Mach from a shortcut on your desktop, the profile is specified in the shortcut.

The SmoothStepper has certain parameters of its own that are unique to it.  The plugin creates a new section in the XML using the name of the device.  In the case of the USB SmoothStepper, the name is "SmoothStepper".  For the Ethernet SmoothStepper, the name is "ESS". If you are upgrading from a USB to an Ethernet, you must re-enter all your settings. 

Here is a link to the latest Ethernet SS plugin.  Open the zip file and double-click the m3p file.

Configuring the Ethernet port

1. The computer's Ethernet port needs to be configured with a static IP address.  Usually Ethernet ports are set up for DHCP, which allows a cable or DSL router to assign a unique address to a device that is requesting an address for the local network.  The best way to describe this is to point you to a website that shows it in pictures.  Please go to this site:

http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&vw=1&articleid=3998

Scroll down to the operating system you are using.

When you get to the part where you click the radio button that says "Use the following IP address", please type in the following:

IP address:  1 0.9.9.8 (or anything in the 10.9.9.x range, but not 10.9.9.9 because that is the address of the board)
Subnet mask:  255.255.255.0

By default it will show a Subnet mask of 255.0.0.0 after you type in 10.9.9.8  It must be changed to 255.255.255.0.

The Default Gateway may be left blank, as well as the Preferred and Alternate DNS servers.

That is all you need to do for the static IP address.

2. You can try running Mach at this point, but you might need to disable the firewall if it doesn't communicate.  When you run Mach, a firewall warning might pop up that says an application is trying to access the Internet.  Give it permission to do so.  It needs to be valid for Public networks and not just Home or work (private) networks.  That way you won't need to disable the Firewall because you are creating an exception for Mach.

Depending upon whether or not the user has previously checked off the box that says "Don't ask me again" when you select a motion control device, you might need to reset that.  In order to do that you will need to have Mach running (which means you will need to be pretending to be running another device such as the parallel port).  Choose the pull-down menu "Function Cfg's".  Then choose the option "Reset Device Sel...".  The next time you run Mach it will ask you which motion control device you want to run.

When you run the Ethernet SmoothStepper plugin, it will try to contact the board.  If this is the first time you are using this XML (profile) file, the IP address will not be set properly.  Warp 9 is working on a better user interface for this so that it flows nicely.  You will be presented with a semi-cryptic message that says:

CTftp::WakeupClient Board does not reply.
Select YES to retry
No to config
Cancel to quit

Click No, and then you will be allowed to enter the Static IP address of the SmoothStepper board (10.9.9.9).  You will only need to do this once, since the next time Mach runs, it will find it in the XML file when it starts.

If you are not able to make a connection, you might need to turn off the computer's firewall temporarily.  To disable the firewall, try one of the following links:
