2021 helix bore

[gms1]

I see in the whats new for 2021 that an option has been added to start/end at the center of the hole. This has changed how the code is output apparently because now If I input 90 in the start angle box, 0 in the sweep angle box it doesn't actually start @ 90 degrees. It starts at a nice random 36 degrees. Is there any way to fix this so if I type 90 it starts the tool in a 90 degree angle?

Do you have perpendicular entry checked?

Works fine here if it is

The biggest change I've seen with end at center is you get a comp move on an arc if you use sweep...did not used to happen...but end at center will correct it.

 

I only caught it because my post barks about comp on arc moves

I usually keep the perp entry off and I don't use sweep.

I'm thinking the start & endpoint of that circle is off on an angle...

Try drawing a circle and chaining that, see if the behavior is different?  or trying using the point and setting the diameter to check for different results

The start & end angle is determined by the plane that the toolpath is in.   So I'd look at the individual plane and see if it's rotated around Z..

This is a horizontal program. So I duplicated the front plane and created a new origin. This program was started in 2019 though so maybe thats it? I tried to repeat this in a fresh session of 2021 and it wouldn't do the same thing.
