You need to make a dummy component first.
Code:
import hal hal.component("dummy") hal.set_p("stepgen.0.maxaccel", "22")

The dummy component makes the module create a shared memory path to HAL.

Thanks, that made hal.set_p() work.

Do you have any suggestion on how to make stepgen decelerate if, in position mode, I have to stop in the middle of a movement?

Would simple_tp be helpful?

It's a single joint jogging component - same as linuxcnc uses.

You could also look at the axis test used in stepconf.
Though I think it stops immediately if you stop in the middle of a jog.
