Scott's CRP4896 BuildScott at LMN Tech Studio wrote to let us know about the 2013 Seattle Design Festival! He has cut over 1500+ parts for the LMN Pavilion using his CRP4896 4'x8' CNC Machine and writes:






"The primary materials are painted 1/2" plywood and 1/4" MDF. The joints of the entire system rely on friction only with no glue or fasteners. The overall size is basically 10'x10'x10'. The machine has held up admirably during this past month of cutting over 25 4'x8' sheets of material. I'd estimate that we've been able to maintain a tolerance of +/- .003" which has been critical since we are counting on that tight fit."

Ethernet Smoothstepper Setup Guide
This guide provides step by step setup instructions for the Ethernet Smoothstepper (or ESS) with your CNC Router Parts Electronics and Mach 3. If you have additional questions or run into issues, feel free to Contact Us.
Additional documentation can be found on the Warp9 website (the manufacturer of Smoothstepper), where their manual can be downloaded.



A PDF version of this guide that you can print or view offline is also available for download here:
1.Installing Mach 3 and Pre-Configured XML File
Please install Mach 3 first before attempting the instructions in this guide.

You will also want to follow the instructions to download and install the XML file from our site that matches your electronics as this file will be modified during the ESS installation. Install it before installing the ESS to avoid duplicating some of the software steps outlined below.


2.Supplying power to the Smoothstepper and setting jumpers
The ESS requires 5V power to operate, and can receive it by one of two different methods (but not both!):



If you are using the ESS with PMDX-126 card (as sold in some of our Nema 34 kits), you can supply power to it via the 26 pin cables supplied with your kit – these are equipped to carry 5V power on pin 26 of these connectors. Please see our Ethernet Smoothstepper Installation Guide for Nema 34 Guide for details on setting the jumpers properly on both the ESS and the PMDX-126 card.
For PMDX-126 configuration, the Pin 26 5V Jumpers should be ON for Ports 1, 2, and 3, and nothing should be plugged into the External 5V Input.

For installations with other breakout boards (or with the G540), an external 5V power source needs to be connected to the green power terminals on the ESS. For G540 or other breakout board configurations, the Pin 26 5V Jumpers should be OFF for Ports 1, 2, and 3, and 5V should be supplied to the External 5V Input. There are multiple ways you can power the 5V on the board -- a 5V wall supply, a small regulated power supply, or DIN Rail power supply. A USB cable can also be used to power the system from your PC. Typically, the red wire from a USB cable is 5V, while the black wire is V-, but cheap cables sometimes do not follow proper color coding, so it is worth verifying with a multimeter before plugging in. It is very important not to wire 5V power backwards, as this can damage the board. You can disregard the data wires. If you have questions on this, please Contact Us.

For all configurations, the Config Jumper should be OFF. This jumper is only used for troubleshooting, and sets the board to BOOTP communication mode for communication with a utility program called the configurator when ON. In this mode, Mach3 is not able to communicate with the ESS. For all normal operations, this jumper should be OFF.


3.Install Ethernet Smoothstepper Plugin
This plugin can be downloaded from Warp9’s website. You will need to unzip the file.

You should then be able to double click on it, which runs the installer. When the installer has executed successfully, you should see a message that it has installed:

This simply renames the file extension from “.m3p” to “.dll” and copies it to your C:\Mach3\Plugins folder. To verify success, you can check to see if the file is present in this folder:


4.Plug in Ethernet Cable
Your Ethernet cable should now be plugged in to both your PC and the Ethernet Smoothstepper.


5.Configuring your PC Ethernet Settings
The ESS communicates with your PC over the Ethernet port, so your PC needs to be set up to talk with it. Please note that the ESS should be connected directly to the PC port (not through a router or switch). This will disable wired LAN/internet connectivity on this port, so if you also require this connectivity, you will need a wireless adapter or another wired Ethernet card.

First, go to Control Panels from the Start or Windows menu:

Select “Network and Internet”:

Select “Network and Sharing Center”:

From the pane on the left side of the page, select “Change adapter settings”:

At this point, you may find you have multiple network adapters. Make sure to select the one that you have plugged into the ESS, and make sure that the adapter is enabled (does not have a red X next to it). Right click the icon and select “Properties”.

You will then select “Internet Protocol Version 4 (TCP/IPv4”) from the list of options, and click the “Properties” button.

Select the “Use the following IP address” button, and then configure the settings as shown below. IP Address should be 10.9.9.1, subnet mask should be 255.255.255.0:

Exit back to the Control Panel main screen.


6.Allowing Firewall Access for Mach / ESS
Once back to the Control Panel main screen, click on “System and Security”

At the next page, under “Windows Firewall”, click on the “Allow a program through Windows Firewall”:

You will then need to click on the “Change Settings” button in order to allow programs through the firewall:

After you select this, scroll down in the list until you find either “Mach3 CNC Application” or “Mach3 Loader” (depends on version of Mach and plugin). For either of these, check the box to the left of the program, then make sure there is a check in the boxes for both Home/Work (Private) and Public. The ESS sometimes makes use of either type of network, so needs to be allowed through on both:



7.Launch Mach 3 from the Loader
Launch Mach 3 by double clicking the Mach 3 Loader icon on your desktop. This will allow you to select the pre-configured XML profile that you installed in step 1.

Select the profile you installed earlier for your machine (the one shown in the example below is for a G540 based system):



8.Configure IP Address for Smoothstepper to 10.9.9.9
Once Mach opens, you will be given the chance to select what interface to use. Select the ESS interface. We recommend leaving the “Don’t ask me this again” checkbox unchecked until you have everything confirmed and working.

You will then likely be greeted with the following error message:

Click “No” to config, which will bring up the following screen with 0.0.0.0 set for the SmoothStepper Board IP Address. Change this IP Address to 10.9.9.9 (the default IP address of the ESS):

If everything is configured correctly, you should see the following page:

Select “Yes” – some of these values can be edited later if necessary, but in general the default values work quite well. You should then see the following menu:

Hit OK to dismiss this message.


9.Save settings and shut down Mach
To save settings, simply select “Save Settings” from the “Config” menu. You can then exit Mach by selecting “Exit” from the “File” menu. This will complete your installation. The ESS settings are now saved in your XML profile, so the next time you launch Mach through the loader, it should connect automatically.

Auto Z Touch Plate Instructions
The CNC Router Parts Auto Z Touch Plate system allows for quick and precise setting of tools to different work heights.







Using the Auto Z Touch Plate with Mach3
Setup of the Auto Z Touch Plate is fairly straightforward:
  1. Plug the unit in.
    1. For a Pre-wired Nema 34 system, just connect the two leads on the unit to “Signal” and “Ground” on one of the 3 pin connectors supplied with your panel, and plug into the red input signal board.
    2. For a DIY system based on the PMDX-126 breakout board, just connect the two leads to an input pin and a common on J11.
    3. For a G540 based system, you will need to wire one of the leads to an available input (pins 1 through 4 on the G540), and the other lead to the G540 power supply common (V-, on pin 12 of the G540).
  2. Set up the input pin for the “probe”.
    We need to have it configured as an active low input, and we need to use an available open input. The example below shows pin 15 being used, but if you are already using pin 15 for something else (such as a limit switch or estop), you will need to use another available input. There are 5 available inputs on a parallel port – 10,11,12,13 and 15.Pin 15 is mapped to the estop for the G540, and pin 10 is mapped to the estop on a PMDX-126 system, so these may not be available depending on your situation.

  3. Add the Visual Basic code to the “Auto Tool Zero” button
    1. Go to the Operator menu and select “Edit Button Script”; the configurable buttons on the page will start flashing.
    2. Click on the “Auto Tool Zero” button; this will bring up a window with code you can edit.

PRO Rack and Pinion Assembly Instructions (Previous Version)

PRO Rack and Pinion Assembly Instructions (Previous Version)
Please Note: these instructions apply to the previous (pre-2014) versions of our PRO Rack and Pinion drives. For the current version PRO R&P drives please see refer to the current PRO Rack and Pinion Assembly Instructions.
These instructions go through the steps required to assemble your CNC Router Parts PRO rack and pinion drive. While the majority of the photos shown are for our Nema 34 rack and pinion drive, most of the same steps apply for the Nema 23. Any special cases that apply differently for the Nema 23 are shown separately.

If you are using the PRO drive with CNC Router Parts extended linear carriages, the first step in setting up your rack and pinion drive is actually to modify the extended carriage to which it will mount. This requires simply replacing one of the bolts through one of the fixed (non-adjustable) bearings, as shown in the photos below. Remove the 30 mm bolt, and replace it with the supplied 40mm bolt so that it sticks out the back of the carriage. This bolt provides a mounting point for the EZ-tension system included in the PRO drive. Once this is done, install the carriage on your machine as normal before proceeding with the rest of these instructions.









Once your carriage is configured, the actual R&P installation can begin. The next step is to mount the supplied pulley to your motor.



You will want to set the height of the pulley such that it aligns fairly well with the mating pulley on the drive spindle (combined gear and pulley component) when installed, and so that it does not stick out so far that it risks interfering with a rack clamp. Approximate positions of the Nema 34 and Nema 23 pulleys with respect to the motor boss are shown below:


Nema 34 pulley spacing

Nema 23 pulley spacing


Once the pulley is installed, you can attach the motor loosely to the rack and pinion drive plate. First, align the hex nuts in the slots on the back side of the rack and pinion plate, and place it on top of the motor.



Once these are in place, install the socket head cap screws into the hex nuts. Do not tighten them completely at this time, as the motor needs to be able to slide freely to install the belt.



Next, place the drive spindle spacer washer on top of the drive plate -– see picture below. Note, for the Nema 34 system, this is a thin flat washer, while for the Nema 23, this washer is slightly thicker.


Nema 34 Spindle Washer


Place the drive spindle on top of the washer, and install the belt around both the motor pulley and the drive spindle.



Next, install the drive spindle shaft using a large flat head screwdriver. Note, this shaft needs to be tightened all the way down until no more rotation is possible. For the Nema 23 spindle, there will be some resistance to spinning the drive spindle until the shaft is fully installed, which will flatten out the lock washer.


Nema 34



The PRO Nema 23 spindles use a washer near the head of the spindle shaft.
This washer is not used with the Nema 34 PRO spindles.



Nema 23


At this point, it is time to apply tension to the belt. A quick clamp can be very helpful here, and will allow you to apply tension to the belt and hold it in place while you tighten the mounting screws underneath.



You are now ready to mount the drive to your linear carriages or other linear bearing system. To do so, align the PRO pivot with the tapped hole in the carriage for the pivot bolt, and then insert the pivot shaft and tighten with a wrench.





Next, install the tension system brackets. Attach the drive tension bracket to the R&P plate using the supplied bolt. Attach the carriage tension bracket to the extended 40mm bolt using the supplied hex flange nut.




Drive tension bracket





Carriage tension bracket


Lastly, install the two M8 washers and tension spring onto the tension shaft, and connect this arrangement through the carriage tension bracket into the threaded portion of the drive tension bracket.





Your completed assembly should look something like the following:



Once you install the system on your machine, tighten the tension bolt until you get solid engagement between the rack and the pinion gear. The amount of tension you apply depends on the mass of your system, the acceleration settings you use, and the torque of your motors. More tension will provide more resistance to the pinion gear popping out of the gear rack, but can also accelerate wear on the pinion, so make sure to leave at least some travel in the spring.
