Looks like Simplify3d is not supporting the G28 to G32 commands for bed leveling.
They are not really slicing oriented commands. Does S3D have a facility for defining Start GCode? That is the place to put it.
They do in the scripts tab. I will try it there instead of the communications tab that i was using.
@Neil_Darlow That was a good tip. I was able to implement the bed leveling at the start G code.
I have used autolevel. Just add the gcode to the start script.
Yes i have found that it works like that. Before i was trying to implement it from the communications tab and it wasn’t working from there.
