Rich Auto DSP Controller Upgrade

 

Richsutosm

 

The Rich Auto DSP controller is used in a lot of various CNC machines.  It is a DSP based control system that contains a small circuit board located in the CNC machine control box and a pendant system that is connected via a cable.

We are going to go through how to connect a our laser upgrade kits using the spindle output from the controller.  This upgrade will require getting a DPST switch to switch between the laser and the spindle mode due to the relay on the spindle.  This is an easy upgrade and will get you up and running with your laser in no time.  You will then just need to figure out how to mount the laser on your machine.  Let’s get started!

Electrical

In the control box of your cnc machine, there will either be a little blue circuit board or a black controller.  The newer version of the RichAuto DSP controller will be packaged in a metal box.  The older versions will have a “0501” in the name, while the newer ones will have “A11” in the name.  It will be the same method to connect either way, so no problem there.  Here are some pictures of the controller.

There is a section of outputs on the board that are for the spindle control.  It is on the top right connector.  Here is the picture of the older style controllers:

Here is a picture of the newer “enclosed” version of the controller:

Most machines will have a “spindle relay” that is controlled by the Y1(S0) signal. Since the laser will turn on and off a lot of times, you want to not have the relay for the spindle turning on and off this much.  So we will add a DPST switch to the circuit so you can switch between the laser and the spindle.

Here is the wiring diagram for this:

Step By Step Instructions:

  1. Find the Y1(S0) wire.

2. Take out the wire that is there and replace it with the NEGATIVE signal from the Laser Driver input connector.  If you use the DPST switch, then this will be on the LASER side of the switch.

3. Find the +24 terminal on the RichAuto controller.  Insert the POSITIVE signal from the Laser Driver input connector into the +24 terminal.  There probably is going to be another wire there.  Do your best to get both of them in the same screw terminal.

4. Take the wire that was in the Y1(S0) connector and connect it to the DPST switch on the SPINDLE side.

Now that you have it all connected, lets go over what you need to know about configuring the controller.

Controller

The RichAuto system has a pendant for control.  You will need to navigate some of the menus to make a couple of changes to get the laser to work properly.

When the Laser is to be used the Spindle Delay will need to be set to Zero.  Spindle Delay allows the spindle 4 seconds of warm up time to reach the proper speed before beginning the operation. Unfortunately, if this is not set to Zero, the laser will sit for 4 seconds after activating before beginning the engraving process.

To change this setting:

  • From the main coordinate screen, Press MENU.
  • Machine Setup should be highlighted. Press OK to select.
  • Scroll down to highlight the Spindle Setup. Press OK to select.
  • Highlight Spindle Delay. Press OK to select.
  • The Spidle Delay settings will be displayed. Highlight the Spindle ON setting and press the Delete button.
  • Enter the new parameter of (0.00) and press OK.
  • Do the same for Spindle OFF and make sure it is also set to (0.00).

Once finished, press the Stop/Cancel button until you have returned to the main coordinate screen.

Mechanical

This controller is used on a lot of different machines, like the Laguna CNC and OMNI to mention a couple.  We recommend putting the laser driver close to the controller box, or even in it.  Then you can measure the distance needed to get through the cable chain to the gantry.  The laser and fan extension cords are here:
