Total noob here. This video topped all the words I've read on the I and J thing. Thanks

This is one of the better descriptions for I and J in the G-Code that I have seen or read. It is not complicated, but how to describe the I and J apparently can be difficult for some to describe. I can actually now see two ways to indicate I and J, and for more complicated milling, I can now throw in the K values for milling. Thanks for the description that we can understand.

This video made the topic so easy to understand. I've been using g-code on and off for uni for the past 2 years. Have always struggled to understand how to get circles as you want them. You guys just helped me to ace my exam. Thank you!

Awesome explanation. Doing fret slots for multiscale guitar. Was confused about starting and end points, Also can generate curve with radius command. Will test but I think I'm heading in right direction. Also you can use camotics to import your gcode and will give a visual realtime representation of toolpaths and it's free.

You can also use an r value with a g2 or g3 command to achieve an arc

Very nice just knowing X Y is the end point helped so much I see people cut circles in two steps 180 degrees each is this necessary or can a 360 cut be done with one G2/G3 ? This used to be so confusing because people want to start in the center of the circle and you also have to account for the bit size and subtract that out too. I have yet to see a formula using Xc Yc for center and Xbr Ybr (bit radius) ! Yes I'm a software engineer!

Some gcode senders will do the entire circle if the end point is the start point. Grbl will only do 1/2, then you can do the other half. Yes there is a bit of math for the bit diameter.

This is great. Is there a way to form an arc that has a different that has a different x-radius from its y-radius like an ellipse?

Not with a simple gcode. You would need to plot these with small segments. This work would e better suited for CAM software.

is there such a way to do an arc with all three axis? or at the least arching on a plane say YZ while moving X?
@Bobscnc

You can add a Z component as well. The principle is the same, Just at the z and the k. The k is the distance to the center of the arc in the z direction. (XYZ) (ijk)

I’m trying to curve a diagonal line to connect my initials, how would I go about doing that? Like how would I find the center point? I’m new to this G and M code. I want to connect the bottom corner of my M to the top corner of my H. My initials are AMH.
