Manual tapers
I wonder if there is an easy way to give the z axis an angle for cutting a taper manually?
Thanks Patrick

The ability to cut tapers is built-in to the turning, facing and boring tabs.

I was thinking about moving the the X and Z together at an angle and was wandering if it can be done in hal.

Yes, quite easily.
Potentially using a HAL sum2 component: linuxcnc.org/docs/2.8/html/man/man9/sum2.9.html
You could sum Z and X before passing to the motor, with gain1 set to zero normally, but set to a value (halcmd prompt) as needed.
But, really, you might as well use CNC.
Here is an example of my macros in use (including a taper):

You could use external offsets to achieve this

Probably better, as that will better comply to joint limits.
But I still don't think it is a sensible idea

but external offset by angle sounds interesting.
I thin I will start wit the macros and if i need to waste more time I will dive into my braindead ideas.

If you are running LinuxCNC 2.8 / 2.8.1 then there is a sample config in sim/gmoccapy/lathe-configs/lathe macros with the macros all set up and ready to play with.

I hope I‘ll get the missing parts, so I can start assembling the control for my lathe.

You are probably right
