Set tool offset to value from tool table and enable tool offset.
G44 is a G-code used to activate the tool length offset compensation. Tool length offset compensation is a feature that allows the machine to adjust for the length of the tool in the spindle when performing certain operations. By activating the tool length offset compensation, the machine will move in a path that compensates for the length of the tool, so the cutting edge is at the correct height according to the program.
The G44 command is typically used before or during a specific operation, such as drilling or milling, to ensure that the machine is following the correct path that compensates for the tool length. It's usually followed by H word to specify the tool number, in G44 Hn, n is the tool number.
