Limitations during program run
A graphical representation of a running program is not possible if the
microprocessor of the TNC is already occupied with complicated
machining tasks or if large areas are being machined. Example:

interrupts the graphics and displays the text ERROR in the graphics
window. The machining process is continued, however.
