G02 /G03 accuracy issue won't allow my code to load was created by berntd
I am wondering if there is a way to use the G02 and G03 commands in G90 (absolute) mode instead of G91 (relative)
I wanted to do it but every time, it tells me that my start radious is differnet from my finish radius.
For example, yesterday, the value I fed it are correct and they do compute on r1 = 14.848 but on r2 it gets 14.862.
It just won't accept this and load / run that code.
I am guessing that these are calculation tolerances and they seem unavoidable.
Can I somehow set the calculations or tolerance to round better or just accept such a small error?
Regards

This has come up before. I don't remember if the arc tolerance is easily adjustable but I don't think it is. How are you generatingyour code, what CAM program? Most have a setting for how tight the tolerance need be. Also are you working in inches or mm?

Hi, I am working in metric / mm
I use Gedit (text editor on Linux) to write the code directly. It is really just a simple path and the numbers are straight forward.
