Spain imported CNC milling machine 8055, with grid system. How to continue machining without returning to the reference point after the machine tool is cut off and restarted halfway?

You can change your mind,

The numerical control of our company. Does Haas system have a "program restart function"? You can specify the program segment number. The previous feed is simulated by the system itself, and then processing is started from the program segment number you need.

Look at the instructions, your system should have similar functions. Or call the seller for advice.
