Hi Terry, A 'tool check' type function would be very useful but it doesn't look like anyone is likely to have enough time to put into this in the foreseeable future. I would like to have a go but I simply don't have the time to invest in learning the inner workings of the trajectory planner.
To be honest, the amount of coding needed for a 'tool check' function is likely to be pretty similar to that needed for full movement while paused. The difficulty is in resuming from halfway through a blended move. Not only are you potentially half way through a line of code but in the case of a blended corner the cutter may not even be on the commanded tool path.
