How Accurate is my SYIL X7?

In this video, I mill a simple Circle Diamond Square model and then measure the part for accuracy. Disclaimer, I don’t have a metric micrometer, so I’m using an outside micrometer with an accuracy of .0001” and converting to metric. I plan on taking the part to the metrology lab on campus to measure again.
Additionally, how I tool-path and mill the part has a huge impact on the ultimate accuracy. For example, the bore seems the most inaccurate, but in my opinion that is more likely due to the tool-path versus the capabilities of the Syil. It did wonderfully everywhere else.

This video should be titled, How Accurate is my CAM? I have learned so much about my machine and Fusion 360 since making this. The SYIL is very capable and accurate. Definitly more consistent than me. 😁

Nice video 👏🏻, waiting for more videos about the SYIL X7

Looking really good!

I just did that same test on my small wood cutting CNC (bought at a thrift store for €25, replaced the old controller with an Arduino running GRBL). Apparently, it has different pitched lead screws on the X and Y. 😅

-0.20mm for a 10mm bore seems ridiculous for such machine, is there any update on why this happens?

Why was the bore accuracy so bad? What can Syil do to make it perfect? 😮
