the help document says :
Note Configuring and clearing buffers is a processor-intensive operation on the motion controller that requires the allocation and deallocation of memory. You should configure and clear buffers only when motors are not moving and onboard programs are not running. For example, if you wish to execute three simultaneous contouring operations on axis 1, axis 2, and vector space 1 (with axes 3 and 4), you should first configure all three buffers before starting any of the operations. You can start the contour operations independently, and at different times, but should wait until all operations are complete before clearing any of the buffers.
and i tried to conduct two contouring operation on two vector space. and tried to clear or configuring buffer for one vector when another one is still moving. so that i can start or end the movement at any time i want,and it is ok.no error. but when i tried add a buffer breakpoint output along with each vector movement. the bp doesn't work if the other vector is running . is there anyway to solve this problem.
