HELP:radius to end differs from radius to start

I'm continously getting this error from a file I am generating with mastercamx





so i checked the gcode file and i think the problem is here somewhere

i was triyng figuring out how to change the radius but it seems not so simple.

Can anybody help me with it?

it would be very appreciated! :silly:

The error is between line N8274 and the previous one. Can you post the previous line?

those are the previuos lines

The error is that for the machine to move from:

N8272 X15.542 Y1.368

to

N8274 G2 X15.577 Y1.383 I.111 J-.351

using that defined center is impossible as the length of the segment that goes from the center to the first point is different than the length of the segment from the center to the second point.

Two remarks: If this is programmed in mm (I do not know, you did not told), then this arc will almost be line a straight line, as its curve have a maximum distance from the line of about 0.0005mm, probably much less than your machine resolution.
If this was generated automatically by a CAM, probably you need to add more resolution in the output, more decimals as the rounding can be the problem.


Never less, if you change the second line from

N8274 G2 X15.577 Y1.383 I.111 J-.351

to

N8274 G2 X15.577 Y1.383 I.1269 J-.3444

The machine should understand this segment, but there is the possibility that fails in the next (or later) ones, as there are many arcs that probably will suffer from the same initial problem.

thank you again!!! you just solved my problem, now i'm trying to figure out how did you!!
again again
Thanks!
