Spent a few hours running code through LW3 for my little Sherline mill.

I am posting my code out of Fusion360 and loading it into LW3. I am getting some errors if I have Lw3 in CNCweb mode when loading the gcode. It will load in ok, but when I go to “Generate G-Code” in the console I get the following;

gcode-parser.js:1306 Infinity seconds estimated
gcode-parser.js:194 adding to scene

This code works fine if I take it back out of CNCweb Mode.

@Joe_Spanier ​ I load my gcode from LW4 directly into standard LaserWeb and just press play. No generate gcode

Don’t use Generate G-Code when you’re loading externally-generated G-Code. Your external cam already generated it.

OK. I’ll try that. It always drops you into the generate gcode tab after you load it.

There’s no workflow in the manual for “loading gcode” hence the question.

Few people load gcode, so both the UI and the manual tend to neglect it.
