End Remnant Cut
In End Remnant cut, the head need to travel beyond the sheet edge to complete the cutting such that the part can be removed easily. Hence, it is required to lock the cutting head motion before certain distance reaching the sheet edge, such that the head is not driven down in absence of sheet below.
-
Split the last motion command into 2, such that 1 command is within sheet and the other moves beyond the edge of the sheet.
-
Insert the “M1011” command between the above 2 motion commands, such that after the first command, the head will be locked and moved outside the sheet with the second command.
