I confess, in the case of tkemc and mini, the backplotter does not erase overlapping points when running a repeat of the same tool path. It simply adds the new data to the plot so you wind up with many spots stacked on top of each other. It is not a memory leak, just an ever enlarging file. I suppose that I was to sloppy a coder to write a test the color of the canvas at the location of the next point and erase if they overlapped. Either that or the ancient Gateway mobo was just to slow to run both the machine, the display, and the test at the same time.
My workaround was to shut down the backplotter occasionally and simply not run it after I'd confirmed the part program and went into production.
