I have calibrated my arc droid and then proceeded to use the trace function to create a bracket straight lines and a couple of radius, after I saved it and then tried to “run” it to see if it traces the same shape as I originally intended and it has added some drastic jogs in the radius’s. What am I missing?? Thanks!! ![image](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/1X/b5b5201c2fca4c8e0c06d519c04982043860507d.jpeg) ---

Kinda hard to tell what you are doing…. I only see one area that looks like it should be a radius. It also appears you are working outside of the general working range of the arm. Re-zero the part to centralize better. Were you picking points from a paper drawing? Nothing wrong with that. When it comes to tracing a radius I much prefer a rigid pattern for that with a continuous click of the stylus while making the sweep. I often cut a full circle out and then cut the outline leaving the portion of the radius I want. If picking points on the radius to click on keep the intervals small. ---

I ran into this once and found out that in the upper left of the screen when you are tracing there are 3 icons i believe and if the center one is on (i think it was the center) it is some kind of snap or something that goes to nearest grid point. Sorry I dont know what it is or does but it does what you are seeing. Took me awhile to figure out what was going on. ---

Same here be sure that the snap feature is off. As in “snap to grid” great if you need it, but not helpful if you don’t.
