please print an object with up to four color changes but more than one. My issue was always with the first color change of every object no matter what layer had the 1st color change. Because I didn’t know if the problem was somehow with the AMS I made a small dime size cylinder that was four colors with each color being 10 layers. It was not the AMS and didn’t matter what color was 1st.
I caught much grief from the forum when I tried to troubleshoot the problem and even more when I provided the file for testing so I am hesitant to discuss my fix on my P1S. I can easily reproduce the problem and the fix has stopped all layer shifts for over the last 2,500 hours of printing, I just finished an object that was four colors and over 1,700 color changes.
Tell me the results of more than one color change. Is the layer shift always the 1st color change? Regardless of the color or layer? Is it only the 1st color change? Can I see your object or objects? While the testing may seem a little silly it proved the problem, solution, and I learned a lot.
