Jogging at a certain angle (lathe mode)?

I would think you would need to rewite simple tp for multiple coordinated axes.
But as you inferred the TP is exactly that.
I don't know why the TP is not used for jogging - that would be an interesting question to get answered. My guess is because it was easier.

Full trajectory planning and jogging needs different kinds of planning: TP needs to be able to (pre-)blend segments, while simple_tp needs to be able to re-plan in realtime, handling nonzero initial conditions (acc, vel).

Well I assumed the TP would need additional code to do jogging.
The two jobs are not that far apart. setting an MDI G1 X1 f1 and then aborting is very similar to a keyboard jog.

The Fanuc control on the Schaublin 125-CCN has something like that implemented, so you can set an angle and then use the jog wheel to move along the angle.

I know some people will likely be rolling their eyes but a custom kinematic might be a solution for this.

If you are okay with stopping completely between each new jog target position, then yes, they are very similar. But think about jogging with an MPG. You really need to be able to "pick up" the current motion and continue to a new target.
