This is unexpected. Radial is the default for these functions about
everywhere
else. This should be made more explicit.
I would imagine that most CNC operators will expect degrees. Can you
imagine trying to type in a right-angle in MDI in radians?
G1 @20 ^ 90
is far more practical than
G1 @20 ^ 1.570796327
I agree with Andy on this one Steffan, for CNC, radians is a PITA.
My current project is a hard maple vise screw, about 18.5" inches
long. To carve a
2 start, 12mm pitch thread is 187,000 degrees, LinuxCNC tracks that
perfectly. As a
retired broadcast engineer, everything I've had to do has always been
done in degrees.
Including measuring guy wire tensions by the intercept method using a
riflescope is
SOP.
Uh, sorry, missunderstanding. I was spending too much time in weblate
and forgot how this may be read without that documentation-context. I do
not suggest that you should change the function, my comment only refers
to the documentation that should explicitly state 0-360 or something to
render it absolutely clear to everyone. But admittedly I still hope to
find the constant Pi defined somewhere and then 90 is about as easy as
Pi/2.
Actually, its not 0 to 360, linuxcnc can track to any reasonable degrees.
I have some thread carving code that move's y a bit over 300 mm's, while
turning B from 0 to 187000 degrees.. arriving at that point, I turn B
187360 the clean
up the stop point, then turn it back to 187180, then take y back to the
starting
point while driving B to 180. That cuts the threads 2nd start thread. Pix of
one of the screws on my web page in the sig.
Cheers,
Steffen
