CNCCookbook's G-Code Tutorial: G Code Learning What does G28 Return to Reference Position G Code Do? G28 is one of those odd g-codes that you don't use very often, but when you need it, it's pretty darned handy.
For example, the zero return position is the origin point for fixture offset (machining centers) and geometry offset (turning centers) entries. Most machine tool builders place the zero return position close to the plus over-travel limit in each axis, Some machines require that one or more ...
Tips for Designing CNC Programs That Help Operators The way a G-code program is formatted directly affects the productivity of the CNC people who use them. Design CNC programs that make CNC setup people and operators’ jobs easier. Read More ...
on what happens when using G28. May also want to have a look at G30 and G55 commands. Home can also be the same as Machine zero. So if one does not understand some of the cnc basics and uses commands ( G53, G28, G30, G5x, G0, G1) to move the axis... the axis may n...
Mach3 Version 4 is much more compliant with the standard, but in saying that not many modern CNC controls follow the standard to the letter, Mach3 will be the same, there are enhancements and omissions and as such running any code created for any other G-code control must be run with ...

部分控制器使用G92指令确定工件坐标系。对刀时需定义工件坐标原点,原点的机械坐标值保存在CNC控制器的G54～G59指令参数中。CNC控制器执行G54～G59指令时,调出相应的参数用于工件加工。采用系统缺省的后处理文件时,相关参数设置正确的情况下可输出G55～G59指令,但无法实现G54指令的自动输出。

for that part of the screen. G28 home location information is given in section 5.6.1.4 of Mach3 CNC Controller Software Installation and Configuration manual. It states:The G28 coordinates define the position in absolute coordinates to which the axes will move when a G28 is executed. They ...
