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. 😁
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. 😅
That's cool. We also run a wood-cutting CNC router in the woodshop. I'll admit that's where I got the idea for this video. We're in the middle of using a micro-controller to make a manual pulse generator (MGP) for the router. It's an interesting project. I definitely need glasses and a magnifying glass to see well enough to solder those tiny pins.
I'm much more familiar with the Syil now. My biggest mistake during this test piece was pushing the tool path too aggressively. The helical bore wasn't a bad strategy but I think my final contour path was too aggressive and my endmill deflected. For better accuracy, I like to leave less on the walls for the finish pass and even follow up with a final spring pass. I programmed repeat passes on the square and diamond and the measurements were better.
@@PowerForgeWorkshop A lot of people, especially when first getting into CNC programming, don't realize there is a conversion that needs to be done for circular interpolation especially when dealing with bores. Some CAM software and machines can do the compensations for it, but a lot don't, so the feed rates people normally post out are much higher than they should be. There is a multiplier you need to apply to the feed rates: (Diameter you're cutting - tool diameter ) / (Tool diameter) Example: Cutting .375 inch bore with a 4 flute 1/4" tool (RPM at 3000, chip load per tooth of .001) Linear feed rate: 3000(RPM)*.001(chip load)*4(# of flutes) = 12 inches per minute Circular feed adjustment: (.375-.250)/(.375) = 1/3 Adjusted feed rate = 12*(1/3) = 4 inches per minute

Nice video 👏🏻, waiting for more videos about the SYIL X7
Thank you! More videos are definitely coming. I still have much to learn.

Interesting test. Thanks for sharing!
Thanks
Always good to test your self.
-0.20mm for a 10mm bore seems ridiculous for such machine, is there any update on why this happens?

@@PowerForgeWorkshop I use gwizard calculator, it calculates the deflection
@@dancollins1012 Cool, I'll check it out.

Circular feed adjustment: (.375-.250)/(.375) = 1/3
Adjusted feed rate = 12*(1/3) = 4 inches per minute
@@adriand.896 Awesome! Thanks, I'll put that in my tool box for future use. I already have your comment copied to a word doc.
