The chart at 3:38 REALLY threw me off! It was stating that the J is calculated as: J = CenterPoint - StartPoint It took me a couple of hours to figure out that it was an error. The calculation is: J = StartPoint - CenterPoint It was then observed that at the next scene the code had the start point at 2.0 instead of the 1.0, contrary to what was shown on the chart.
The calculations are correct as shown; however, the step-by-step calculations are for the inner circle (shown at timestamp 6:43). The inner circle has J values of 0.5 and -0.5. The larger diameter circle (shown at timestamp 6:50) can be calculated using the same process, and you are correct that the larger diameter circle has J values of 1/-1. You can download a copy of the executed gcode by clicking the "G02 / G03 circle" url, found in the description.
Why not do a perfect 360 hole in a single block. G91 G17 / G02 X0 Y0 I1.375 J0 (Pretending i'm using a 1/4 cutter)?. It's faster and less dramatic, avoid too much editing or calculations.
Well this explains nothing. Could we have some parameters here? Hole size, cutter comp, arc in or out, positioning in relationship to origin point, center or edge of tool, tool size? Anything???
I love it! Thank You. But always remember tool radius!

Best explanation out there!
Software name please?
Windows Notepad; Microsoft Excel; Universal G-Code Sender
Since G02 is Modal, would N35 still function the same if you took out the G02 from that line?
Obrigado 9y9¹¹1
what do the Ns mean
Where would the Work Offset fit in to all of this? The first G00 line at N15?
Yes, your work offset would need to be defined and called prior to any subsequent operations being called.
Think you may have made a mistake with the J calculation? The Y start point is 1 (not 1.5) and J should be 1 (so not 0.5)?
2 - 1 = 1

I want to create a circle on XZ plane, Not XY plane. How can I do that?
I believe you use only I and K in that case, but following the same concept that he shows for I and J.
Same technique just using X/Z-I/K.

thanks
Good job using sharpie instead of using an actual block.
X treamly cool

This still doesn’t make any sense to me wtf
