@Tony : I’ll try to get it done in the next couple of days. The 5v TTL input is the main difference between the JTP and generic drivers. The JTP driver is made to work with a variety of CNC applications so it will convert the 12 fan output and can even bring up a 3.3V TTL. I didn’t think anyone was interested in my mount. Once I test it a little longer I’ll put it up on thingiverse.

There shouldn’t be any blank lines in the i2gc gcode. If there is, make sure you selected laser power on and power off commands in the “GCODE” tab. The commands should be M106 S and M107 for on and off. Once you make these selections once, they’ll be retained for the next use. Let me know how that works out.
