Radius to end of arc differs from radius of start line
« on: November 14, 2018, 11:44:38 AM »
I n mach3, when running a gcode, I get this error message. I was going to look it up in the search box, but the search function is not working. Does anyone know why this is happening? I changed the ij line to absolute, as suggested after in one forum. That didn't work. I am at a loss.

Change IJ mode to incremental, and reload the g-code. If that doesn't work, then it may be an error in the g-code.
Can you post the code?

I removed all the GOO lines at the end of this code because I was getting the duplicate lines error with the GOO lines at the end. Should I have removed all the GOO lines at the end, or just certain ones? Could removing these lines be the problem? I am attaching the original, along with one with the GOO lines removed.

I compared both codes and one is much larger than the other. That is very strange.  And thanks ger, buy I have tried changing it to incremental and back again.

I tried the Gcode with the original G00 lines in place, removed the goo from 2 lines, then replaced it with a new line, as Tweakie instructed me eons ago, it seems. Now it is working nicely. I believe I had a corrupt Gcode o I removed the wrong G00. Whichever one, I sOlved the problem thanks to Ger. If the file wasn't requested I would never have noticed the difference in the files. Cheers to you Ger!

it doesn't help that the 0 and o are right next to each other. I always type in lower case to prevent this and it still gets me occasionally.
