TLDR
The accuracy of Ortur Master 3 is higher than that of xTool D1 Pro.
Engraving effect comparison
At first glance, the xTool D1 Pro just looks a little darker at the same power and speed. The difference can be seen if you take a detailed photo.
The jaggedness of the xTool D1 Pro is even more pronounced.
Grayscale Test
The same grayscale test file was carved using different equipment. Master 3 successfully completed the engraving, but D1 Pro engraved the second line and already started to cut the wood, for safety reasons, I terminated the engraving.
However, from the carved effect, we can find that D1 pro carving the same color, there will be a dark side and light side, you can see the first and last frame especially obvious. The color of Ortur is still more even.
I found a comparison between Master 3 and D1 from the Internet.
