^{Originally posted by KonradJuenger January 21, 2022} Hi,

as a new version is on the horizon, could you include a "moveP" mode for UR robots? MoveP allows for a constant speed profile, which is quite handy for anything where distance/time is critical e.g: 3D printing, drawing with inks,

I've added this functionality in this fork, but since it's a bit of a hack there is no PR. -- But it would be awesome if something like it could be part of the official release! best
