Onefinity CNC Upgrade

The folks over at Onefinity have made a truly amazing new machine with linear rails, integrated controller, and the ability to rapidly take apart and move the machine. We have been working with them for years on the Suckit line of products, so it was easy for us to partner with them to provide a new laser solution for their machine.

Lets get going on how to get this installed!

Kit Contents

The laser kit will contain:

  • 7W PRO or 14W Dual PRO Laser with High Resolution Lens
  • 5amp or Dual PRO Laser Driver with Integrated Safety Features
  • 10′ Laser and Fan Extension Cables
  • Onefinity Laser Input Cable
  • 6amp Power Adapter
  • Laser Goggles
  • Focusing Tool
Mounting Kit Contents

You will mount your laser driver on top of the control box using the two holes provided. The screws for mounting the driver will be taped to the laser driver electronics package.

Wiring the Laser and Driver

The laser driver will be on top of the Onefinity control box. The laser extention cable will be on the left and go to the laser. This cable is the thicker cable with the white connector.

The input cable to the Onefinity Controller will be the thinner cable with the black connector. It will go to the black dot header on the laser driver to the onefinity controller port marked “laser”.

The fan cable will connect to the port listed as “fan” in this picture below.

Back of the laser driver

The laser and fan extension cables will go up to the Z gantry routed along the Axis to make sure they are not caught in the linear rails. The laser and fan will hook into these cables.

Enabling the laser driver – The Red Reset Button

To enable the driver you need to follow a sequence for safety. There are two safety features required by the Federal Government that you will need to know about. The key switch and the red reset button. Here is the sequence you need to follow to turn the laser driver on.

  1. Plug in the power adapter to a known good outlet. You should see the LED on the power brick turn on.
  2. Put the key into the laser driver and turn it to the right.
  3. Press the red reset button. You should hear a slight “click” with the interlock engaging.
  4. Turn the power switch on by pressing in the “|” mark. Your fans should turn on and you should have one led on.

Mounting the Laser

The laser comes with a “two piece” mounting plate. One you install on the Onefinity machine and the other is attached to the back of the laser. This allows for the laser mount not to hit the dust shoe and you can leave the mount on the machine without interfering with clamps or dust boots.

The laser will mount to the front M5 holes on the spindle holder. We have included M5 screws for this.

Attach mount to the spindle holder with provided M5 screws

Try to get the mount level so the laser will be 1/8″ above the material for the 7W and 1/4″ for the 14W. You might need to move the Z axis down in order to accomplish this.

Adjust the mount so you get the laser at the 1/8″ height for focus on 7W and 1/4″ for 14W.

The 14W will be 1/4″ above the material for engraving. For cutting, set the focus to the bottom of the material. For example, if you have a 1/8″ plywood, set your focus to 1/8″ above for the 14W or at the surface for the 7W.

The 14W version on the front mount set to 1/4″ focus.

Setting Up the Controller

Select the “Tool” option in the menu of the controller. (Three horizontal lines in upper left of display.)

If you have the newest version of the firmware, then select the “J Tech Laser” option.

If you have a previous version of the firmware that does not have the J Tech Laser option, then do the folowing:

The setting “tool-type = disabled” is for use with the Makita router.

For use with the J-Tech laser this needs to change to “PWM Spindle” with the following settings.

  • Max-spin = 1000
  • tool-enable-mode = disabled
  • tool-direction-mode = disabled
  • rapid-auto-off = enabled
  • dynamic-power = enabled

Setting Up Vectric for Lasering

Using the laser in Vectric software is as simple as getting a new post processor. If you don’t have the new laser module plugin, just set up your laser as an end mill. If you do have the new laser module plugin, then put the laser as a laser tool. Here is how to set up both.

For the Non-Laser module users. Follow this link on how to set up the post processor and your tool:

For the laser module users, follow this link to set up your post processor and your laser tool.

The 7W laser tool will be set up like this:

All you need to do to create your laser file is to generate your laser toolpath with the onefinity laser post processor.

The 14W Laser will be set up like this:

Setting Up Lightburn

Lightburn is an all in one laser program that does pictures and vectors in the same program. It is very functional and easy to use. You can download a free trial or purchase it here:
