OK, That totally makes sense, and I was reading the G-Code to the best of my ability and couldn't see you modifying really anything but tool changing but with CURA 4.10.0, it was so weird. I didn't change anything except installing CURA 4.10.0, and this computer had no previous installs of any slicer and download/import your profile. Cura did not work as I expected, even though I'm fairly familiar with the software. I did, however, install the latest PrusaSlicr and the same thing just imported your profile from online, and boom! It worked, no problem!!! I have some measurements that I got wrong that need to be adjusted for the tool changing G-Code, but that was my own doing. It printed perfectly, and I am thrilled! I have heard that S3D (Simplify 3D) and CURA have some issues, as does Prusa, I'm sure, but, for whatever reason, PrusaSlicr worked without a bunch of work. It took me about 5 minutes, and I started printing. I have S3D, and it did work with a little more effort, but to keep costs down, I doubt everyone would jump to S3D except those who own and swear by it. I'd say PrusaSlicr right now is the easiest to use for printing in color. Bill, Thank you for such a quick response. Also, thank you for this forum where we can gather your knowledge and ours to assist everyone looking into and owning anything to ColorPrint. I assume it will be helpful no matter what product is used.
