Most clever way to to create movement macro.

So, okay, I do know enough fundamental trigonometry to calculate the coordinates, but there seem to me that the should be an easier way / leveraging CAD/SLicer to design this.
Basically, I have a delta with a nozzle wiper cheaply and cheerfully attached to the bed, This puts it at a 60 degree offset to the Y axis.

Right now I just use a few fixed coordinates and it works well enough.

But i wanted to add more passes. And math is boring, especially during summer

So, it's a question of moving to initial coordinate, then move 40mm in a 60 degree direction, then move in a few hundreds and repeat the process. Pretty much "Print a full layer over the wiper, but without extrusion of course"

It WOULD be nice if i could just put the wiper on the rear bed mount, as it is perpendicular with X. However, the CPAP hose interferes with the belt at that position.

So, what's the clever way of tackling this one?

@janjoh use G68 coordinate rotation perhaps?

@dc42

Clever! I did not think about that.

However, I think I will first print a new mount which goes in the "front" of the machine on the X axis.

It occurred to me that such an arrangement should at least make it easier to clean the waste from the wiper. (And make creating the wipe code easier as a bonus)

@janjoh another way would be to use the M665 XYZ parameters to rotate the XY plane.
