J Tech PRO Series Laser Machine DIY V4


Fast, Accurate, Dedicated – NEW VERSION V4

The J Tech PRO Series laser machine is an inexpensive way to have a dedicated machine with all of the features of our new 32 bit laser controller.  We have made an easy all-in-one machine that is professional and can be put together in just a few hours.

As the trusted source in the laser community we are happy to present the new J Tech PRO series laser machine.  We feel this is the best engineered free standing laser machine on the market.  We keep taking your suggestions and making improvements.

This version 4 now offers NEMA 23 motors and a new high current 32 Bit Controller to push the machine to incredible raster speeds up to 1500 inches per minute!  With acceleration set to 1000 mm/s^2, or even 1500 mm/s^2 in ludicrous mode, you will be able to raster your engravings at the fastest diode laser machine speeds to get your projects done at 100% power with the 44W laser.  No turning down the laser and wasting energy!

Full linear rails and self squaring limits make the machine easier to put together and gives superb performance with accuracy, repeatability, and super fast smooth motion.  This machine is bigger, faster, and more capable compared to other smaller machines on the market.

Easily stop the machine in an emergency or pause to leave for a minute.  Have access to the key switch on the laser driver.  Everything you need, all in the front of the machine.






Self Squaring Limit Switches on Y Axis

Improved limit switch design allows for two limit switches on the Y axis to square the machine on every homing sequence.  Never be out of square again.






Pre-Assembled Parts for Easy Assembly

We made this machine with assembly in mind.  It is a professional machine, but it doesn’t take two days to put together.  We have engineered it to be easy to assemble and operate.



WiFi and SD Card Support

The new machine has integrated Wifi and SD card capability.  No need to use a seperate computer if you don’t want to.  Make a single file and send it to the machine with your network to run.  Have several machines running at once to make production.  This offers a whole new world not attached to a computer.







Full Lightburn Support

You can use the integrated wifi, or you can connect directly with a computer using Lightburn.  The new machine supports Lightburn fully as this is the software of choice for the Pro Series V2 machine.






Web Interface Control

Use your phone, laptop, tablet, or any device with internet to control your machine.  Includes a full web interface on the machine.
