Refer to M41 / M42 Low / High Gear Override for more information on these M-codes. You can use an M41 or M42 to override this. On machines with a gearbox, the control automatically selects high gear or low gear, based on the commanded spindle speed.
Refer to page M41 Low Gear Override / M42 High Gear Override for more information on these M-codes.
It takes the address code Snnnn, where nnnn is the desired spindle RPM. M03 turns the spindle on in a clockwise direction. X0 Y0 commands the table to move to the position X = 0.0 and Y = 0.0 in the G54 coordinate system. G54 defines the coordinate system to be centered on the Work Offset stored in G54 on the Offset display. G17 defines the cutting plane as the XY plane. Incremental Positioning (G90, G91) for more information). G90 defines axis movements that will be completed in absolute mode (refer to Absolute vs. G00 defines axis movement following it to be completed in Rapid Motion mode. It is good machining practice to place this block of code after every tool change. This is referred to as a safe startup line. M06 commands the tool changer to load Tool 1 (T1) into the spindle. Program naming convention follows the Onnnnn format: The letter “O”, or “o” is followed by a 5-digit number. Denotes the beginning of a program written in a text editor.
