Okay, I got my Snapmaker J1 working with Simplify3D and it seems to be printing fine but when it changes tools the Z-height stays the same when it travels to the home position. Sometimes scraping the surface.
Is there any way to introduce a z-hop in the Tool change script so that the build plate returns to it's original position when it's parked that tool and begins with the other?
Mind you, I'm not an expert in g-code and got simplify3d v5 to work with my J1 by looking at the CURA settings.
