X Carve Compatible Laser Upgrade

*Disclaimer* 

All instructions for upgrading machines are all done at the buyers or viewers own risk.  Lasers are inherently dangerous and all safety measures are the responsibility of the buyer or viewer.  While we provide some safety features on our laser kits, it is not a complete laser machine, so all additional features are up to you when you build your machine including interlocks, fume extraction, and fire prevention.  Inventables is not affiliated with J Tech Photonics Inc. and they in no way endorse these instructions.

These are the instructions for the newest models of the X Carve with the Controller.  We no longer mount the laser driver on top of the Z Axis.  We figured this allows for more upgrades of the Z Axis, including the Z axis slider upgrades.  It also just cleans up the upgrade and makes it easier to install.  We just did our install in under 10 minutes.

If you have the older mounting kit with the laser driver mounted on the top of the Z Axis, then you can find them here:  OLD VERSION OF MOUNTING INSTRUCTIONS

Let’s now get started with the upgrade!

In order to complete the following instructions, you need to purchase the laser and mounting kit.  You can get them here:

44W Metal Mount Instruction Update

If you purchased the new 44W laser and are watching the video below, there will be two changes.

  1. The extension cables are now just one black 4 pin molex cable.  Ignore the two cables in the video.
  2. The metal mount attaches to a different area.  Look below here how to install it.

The metal mount has two screw holes for the mounting.  Install the metal mounting plate on the left side of the router holder.  There are two screws included in the kit for this.  Note, if you have a dust boot, you need to take off the side rails.

For normal operation, use the two lower holes to mount.  For using the rotary, then use the two higher holes.

You can tighten the screws to hold the laser onto the mount tighter for more stability.

We are working on the new video instructions now.  If you have any questions about how to install the laser, please contact us.

Paw Paw’s Installation Video Guide

This video will walk you through the installation steps.  You can also look below for the step by step instructions as well.

Lightburn Software Setup Video

We recommend lightburn software for running your laser.  Here is how to set it up on your X Carve.

Mechanical

You have the choice in the X Carve Kit option to either have a shrouded laser or not.  Also, there is the option to have either the standard or a dust boot.  There are two options to choose from:

  1. Standard Front Mount
  2. Dust Boot Mount

The standard mount will work with a dust boot, but you need to take off the bottom part and leave the rails.  The dust boot mount will have the laser off to the side so you don’t need to remove anything, including the bottom of the dust boot from the machine to use the laser.

If you want an older mount, just let us know and we will get it for you.  We have been offering the X Carve laser kit since the beginning, so there have been multiple iterations.

Electrical

The wiring is pretty easy on the upgrade.  You will need to start with the 10′ extension cables at the gantry and route them back to the laser driver on top of the controller.

For the input signal, simply connect the Molex mini fit Jr. 3′ cable included in the Mounting kit from the laser driver to the controller. You can shorten the cable if there is a lot of extra.  There are two signals you need to connect to:  SPINDLE PWM and GND.

Wire the cable to the Controller:

  • Red Wire (Laser + Signal) to SPINDLE PWM on controller
  • Black Wire (Laser GND)  to GND on X Controller

Here is the wiring diagram for the newer machine:

Laser Commands

Using the pre-loaded GRBL

The newest controllers coming out with the X Carve come pre-loaded with GRBL 1.1, which will have our laser code in it already. No need to upgrade to anything else to be able to run and even do pictures.

It is best to check to make sure your settings are correct though.  You can send a “$$” command to list your settings.  The ones you need to check are:

$30 = 255 (max Laser Power)
$31 = 0 (min Laser Power)
$32 = 1 (Laser Mode Enabled)

You can change the values by just sending the setting and the value you want.  For example, to change the max laser power you send “$30 = 255” and press send.

To turn on and off the laser the command is:

  • Laser ON:  M03
  • Laser OFF:  M05

If you want to use power control for the laser (via Pulse Width Modulation) the laser command is:

M03 SXXXXX

Where the “XXX” is a number between 0 and 255.  So, some examples are:

  • Laser ON 100%:  M03 255
  • Laser ON 50%:  M03 S127
  • Laser ON low power:  M03 S11
  • Laser OFF:  M03 S0 (or M05 will work as well…)

Running the Machine

We recommend not using Easel to control your machine when using the laser.  If you are using the firmware installed on your machine (the firmware that came with your machine) then you can use Easel when routing.

There are a lot of different “sender” programs that will work with your machine.  In the inside of your machine is something called “GRBL” that directs how the machine moves and interprets the G Code file.  The G Code file is the “instructions” and GRBL just needs some program to “send” it to the GRBL that is in the firmware of your control board.

We now recommend using Lightburn Software.  It is an all in one solution for doing vectors, pictures, and running the machine in the same program.  Here is how to set up the Lightburn software:

Using Lightburn on Shapeoko3 and X Carve Machines

 Step By Step Upgrade Instructions

So now that you have the overview on how to complete the upgrade, lets get into the details on how to put it all together.  These instructions show the 1000mm kit installation.  On the 500mm machine you will probably not need the power cord extender.

Let’s get started!

STEP 1:  Put a Zip Tie Holder on the Back of the Z Gantry Plate

We are going to start by routing the laser and fan extension cables.  This zip tie holder will hold the ends of the extension cables in place.

STEP 2: Zip tie the End of the Extension Cables to the Holder

This will make sure your ends are in the right place.

STEP 3:  Zip Tie the Extension Cables to the Drag Chain

Put Zip Ties on the outside of the cable chain and attach the extension cables to it.  If you have not started building your X Carve, put the extension cables on the INSIDE of the cable chain.  If you have already built yours, it is very hard to get them inside the chain, so we opt to just put them on the outside.

STEP 4:  Keep Doing Zip Ties on the Side

STEP 5: Put Sticky Tape on the Bottom of the Laser Driver (you can skip this if you want)

Not needed, but maybe nice to keep the laser driver from moving around.  You can put the sticky tape on the bottom of the laser driver and then place it on top of the X Controller.

STEP 7: Connect the Fan cable to the Laser Driver

STEP 8:  Connect the Laser Cable

STEP 9: Connect the Laser Driver Input to the X Controller

Take the Molex Mini Fit Jr. 3′ cable and connect it to the X Controller back side signals.  You can shorten the Molex Cable if needed.  Connect them:

RED WIRE -> SPINDLE (PWM)
BLACK WIRE -> GND

STEP 10: Connect Input Cable to Laser Driver

STEP 11: Attach the laser mount

Dust Boot Installation:

To mount the magnetic dust boot mount, put it on the bottom two holes on the OUTSIDE of the spindle holder slot.

Front Mount Installation:

For the newest front mount, use the M4 12mm screws for the left side and the M4 16mm screws for the right side.  Put the RIGHT side in front of the slot for the spindle hold down and use the two M4 20mm Screws and Nuts to hold it in.

STEP 12:  Put Zip Tie Holder on Gantry Top

Place a zip tie holder on the top of the gantry to clean up the laser and fan cables.  You don’t need to do this if you want to be able to remove the laser quickly.

STEP 12:  Clean up the Cables and Connect Extensions to Laser and Fan

You can attach the extra cable to the zip tie holder on the top of the gantry.  Then, connect the extension cables to the laser and fan cables.

STEP 13:  Focus the laser

Laser Shroud Focus

If you purchased the laser shroud, then your laser came pre-focused to 1/8″ above the work surface.

If you did not get the shroud, then the focus is set to the bottom of the base of the black heatsink.

You are now DONE!

 Additional Upgrades:

We put a FEIN Turbo vacuum on our machine to suck the fumes out, and we mounted two lasers to our machine so we can do testing here easily with both the 2.8W laser and the 3.8W laser.  You can see ours doing an image engraving in the picture.  Of course you can add laser shielding to your machine for more protection!

Using Lightburn on Shapeoko3 and X Carve Machines

Make sure to press the red reset button to enable the laser driver:

You can read on how to focus the machine in the following blog post here:

Focusing Your Laser 101

Make sure you have all your safety equipment and goggles on before you start your laser.  Always keep a fire extinguisher available as well close by.  We have not had any problems, but it is always a good idea to know where on is when using lasers.

You should not need to do anything to change between using your router and using your laser.  Just make sure you have your laser driver turned OFF so you don’t accidentally burn something when using just the router.

 So there it is!  Now you are ready to start creating!

    I need to be able to laser cut 1/8 thick to 3/8 thick balsa. Which wattage lasers can handle that?

    Also how long for delivery if I order by Jan 15th?

    • jtechphotonicscom March 10, 2016 at 11:58 am #

      All of the lasers will be able to cut balsa wood. The higher the power the faster (and less passes) you will need. The 3.8W laser kit will be the best at cutting.

    Hello will your 3.8w laser kit work with the x carve i am very interested and I want to buy this setup i believe you guys are the first to do this to the x carve

    thanks

      All of our laser kits will work with the X Carve. Yes, I think we are the first for this. We have been selling upgrade kits for four years now and have been successfully upgrading the Shapeoko kits before the X Carve.

    Which parts do you recommend taking off while using the router? I see the laser driver is easy to remove and reattach, but the laser itself seems more difficult. Is it safe to leave the laser attached while using the router? Will the dust not clog the lens?

    • jtechphotonicscom March 10, 2016 at 11:50 am #

      Hi Steven,

      You can take both the driver and the laser off if you want, especially if you are doing a large routing project. It is not that hard to take the two screws off the router mount for the laser mount and remove everything.

      If you are just doing small routing jobs, you can keep the laser on the machine. I put a bag over the laser to protect it. If you leave it with nothing protecting it, then make sure you give the lens a little clean with some alcohol and a microfiber cloth (like you would use with your glasses) before you use it again. If the lens moves while routing, you can put some PTFE tape on the threads to make it stay in place better. If you do this, make sure you watch out for the spring when taking the lens out.

    Just got my laser 2 week ago iy was supose to be use with my i3 printer but decided to wait for the x-carve that should be here by the end of the month. And foud todays these tutorial. I just hope i made the right choise for my carve i decided to get the new x-controler. from my basic electronic knowledge i think i see all the necessary pinout but there is no arduino on this one they made their own controler but look like it’s loaded with the same version has the arduino will the 0.9g GRBL Firmware work? or should i change my order to a less powerfull controler on the xcarve?

    thank you

    • jtechphotonicscom March 10, 2016 at 11:41 am #

      Yes, the laser will work with the new X Controller. Connect the laser “+” signal to the front panel “Spindle PWM” on the X Controller. Connect the laser “-” signal to the “GND” on the X controller. You can use the installed firmware for most things. Full power will be M03 S10000. 10% power will be M03 S1000. If you want to do grey scale picture engraving, our firmware should work as well. Make sure you copy your settings in GRBL before you upload the new firmware. We will be testing this out soon on our own X Controller to verify everything works.

    Can it cut aluminum

  6. Brandon Bellefleur April 22, 2016 at 7:55 pm #

    Hey!

    I want to engrave cork with the laser, and I can’t decide wether the 2.8 or 3.8W laser would be best. I would take the 3.8W one because it would go faster, but do you think it will be too intense?

  7. Yasser April 29, 2016 at 12:01 pm #

    Hello

    I read this many times, but the wiring between Arduino and laser and other wires not clear for me, can you please upload a diagram for this connections it better.

  8. ty January 24, 2019 at 10:28 am #

    Hello guys, i have followed all of your installation instructions and my laser works. I have not been able to use it with any of the software. Is there a software for the laser that is easy to use as Inventable’s Easel?

  9. Gilberto Colon February 6, 2019 at 9:08 pm #

    I have a X-Carve 700mm machine. What is the best upgrade kit I can purchase. I was looking at the 4.2W and I was wondering is there any other equipment that I need to purchase is I get the upgrade packet.
