there may be a parameter that makes it stop at corners, or it could be that the accel ramp is overly conservative.
Now that yo are good at sending and receiving, make sure to store your parameters as they are, and you can play with a few things
parameter 91 is constant contouring on corners. As you approach 90 degrees you WILL get gross positioning errors. One of my machines I tolerate this and reprogram parts that I try to rapid this way, either by putting a .1 second dwell in between two moves, or changing the way it makes the move.
parameter 54 is the accel parameter You can play with it a bit, but make sure the machine is happy with what you choose. Bridgeport chose a pretty gentle
accel ramp, and you feel it on peck drilling. Over harsh and it will beat the machine. The weakness of bosch drives is probably this. The Copley drives I put in one of my retros allow a very steep accel ramp.
