Restrict axis pre-plot

I want my gcode program to rotate a spindle slowly but continuously. I could write
o<repeat1> repeat [some large number of times]
(do one rev of 360 degrees)

but I would like to write

o<while1> while [1]
(do one rev of 360 degrees)
...

When I do this axis quite naturally tries to plot all the points in an infinite loop which causes problems.

So can I tell axis only to preplot the first revs worth of points and ignore the rest? If not how can I run my 1 rev loop running continuously and keep the motion of the spindle smooth between restarts of the gcode program?

Any help appreciated.

Thank you , another case of RTFM but this time more carefully, Im afraid.
