+==== G92/G96 for lathe cutting ====
+In a lathe system, G92 is used to set the maximum spindle speed (in the constant cutting speed mode), while G96 sets a constant surface cutting speed. In the code below,
+<code>N17 G97 S2500 M3
+N18 G0 X14 Z1
+N19 G92 S2500
+N20 G96 S220 M3</code>
+the G92 line will set the maximum speed to 2500 rpm, while the G96 line will switch the system to a 220 m/min constant cutting speed mode.
+In this mode, the spindle speed is recalculated depending on the current diameter (the current X coordinate).
+The rotation speed changes depending on the diameter, so that the cutting tool moves along the surface at a set speed of 220 meters/min. The larger the diameter, the slower the system will rotate the part, and if the diameter is smaller, then the rotation speed will increase. By this logic, the rotation speed can go to infinity when the diameter reaches 0, so G92 is used to set a maximum value.
+In a lathe configuration, both G92 and G50 work the same way if the "S" parameter is used. If the G92 command features an F-code parameter however, then the command is treaded as a threading command.
+For example,
+<code>G92 S2500</code>
+and
+<code>G50 S2500</code>
+should produce the same result (although some users may prefer G92 due to the general convention). However, a command such as
+<code>G92 Z-12 X10 F1
+G92 Z-12 X20 F1 L2 P99</code>
+is automatically recognized by the system as a threading command instead.

+==== G0G53 vs G1/G2/G3 commands ====
+//Keywords: Simulator Displacement Error, Critical Compiler Stop.//
+When using G0G53 commands in machine coordinates, the controller switches to the machine coordinate position and the program coordinates become undefined at that given moment as a result. This means that the G1/G2/G3 interpolation commands **cannot** be used under these circumstances (instead, G0 must be used).
+Therefore, after such a switch, it is necessary to first give a positioning command using G0. This command must be given for those axes that were used as machine axes so that the controller can apply the appropriate offsets for the program coordinates.
+For example, this issue will occur when a macro present within a G-code program will contain G0G53 commands (for instance, the M6 tool change macro), after which the G1/G2/G3 interpolation is used immediately. To go further with this example, the user CANNOT use the following combination:
+<code C>M6T1 (in this example, M6 utilizes G0G53)
+G1 Z5
+G1 Y5 X5</code>
+The code above will lead to a simulator displacement error. Instead, for the example above, the following code must be used:
+<code C>M6T1 (in this example, M6 utilizes G0G53)
+G0 Z5
+G0 Y5 X5</code>
+In this second code example, as the tool change macro uses G53 G0 XYZ, the first movement after a tool change will be G0 (for XYZ). This can either be done in G-code (via a post-processor which will correctly output G0 instead of G1 for that section), or within the tool change macro itself.
