Recently I was asked to make some projects that required me to use multiple colors. I was apprehensive as I was not sure on what I had to do to get the printer to stop at a specific point. I thought that I was going to have to learn how to read G-code and then put a stop in, but turns out it is really easy in the Cura software that we use.
I am going to show how it is done.
Step 1: Figure out at what layer you want the color change.
Step 2: Find Extensions > Post Processing > Modify G-code.
Step 3: Add a script > Color Change.
Step 4: Input what layer you want to pause at (+ 2 layers).
*The additional 2 layers are because (at least with our setup) it doesn’t end up on the right layer.
**More pauses can be put in, just repeat steps 3 & 4.
Step 5: Save G-code.
Step 6: Print as normal.
Other things to mention: (Photos Below - See the first T)
I have added a scrap cube to the print as a starting point as I found out that right after a color is changed and it goes to start the new layer it gobs extra onto the part and causes it to not look right.
Steps to add a specific starting point.
Step 1: Figure out the coordinates of the place you want to start.
Step 2: Select User Specified starting point.
Step 3: Put in coordinates.
Step 4: Save G-code.
Step 5: Print as normal.
