Hi all,

I'm at my wits end. Recently bought the 7W J Tech Photonics laser. We intend to use it on our 4x8 Gryphon CNC table. Presently we just have the router hooked up. I feel like I have connected EVERYTHING imaginable, but I still can't get the mach3 to run the code. typically we do all our programming in Fusion 360, but apparently Fusion isn't a big fan of doing too detailed of work for laser toolpath. Inkscape (with the JTech plugin) WILL make a gcode for laser cutting, but once loaded into mach3, nothing happens.

Here's the setup;

J Tech Driver is connected to Output 1 and GND on the MX4660 (output 1 is pin 17). here is the manual to see (http://www.leadshineusa.com/UploadFi...660hm_V1.1.pdf) starting at page 20 discusses pinout.

Mach3 the set up is complete as specified on the JTech website (https://jtechphotonics.com/?page_id=1436)

Everything should be set up completely. what have I done wrong?

I need the PWM to be configured, otherwise the laser is just on.

thanks for reading.
