Jtech Laser 3.8W issue: help!

[FedericoToro]

Hi all,

I bought a jtech laser 3.8w for my x-carve. My problem is that I can’t make function the laser from the controller. I´ve tried the following so far:

• Tutorial from: Laser Engraving with Easel | Inventables
• Tutorial from https://jtechphotonics.com/?page_id=3565
• Laser works manually so I think it’s not an electrical or installation problem
• In universal gcode sender I can move the xyz axis but nothing happens with commands such as $32 = 1 or M03.
• I have GRBL 1.1f
• I have the first generation x-controller.

Please help, I don’t know what could be wrong… (easel for carving have no issues).

I´m attaching some pictures of the installation.

Thanks!

Most likely you are running into issues due to the changes for laser mode in grbl version 1.1f

I have a version built on 1.0c that works with the standard G-code definitions. You can either use my version, or read the instructions here if you want to continue on with grbl version 1.1f

I use Larry’s version 1.0c with no problems. Works great for spindle work as well as the laser. I also use picsender to send the Gcode. One click and can switch between spindle and laser.

Grbl laser is good
