To change gear you program M41 M42 and M43 for the different gears Hand Em Overįor example this beast is a Mazak Megaturn Mazak Megaturn It Has a Gearbox. The reason for this is that they are different depending on what machine they are on.

That’s my list of M Codes the rest are really boring doing stuff like changing gear ranges and stuff. The spindle will start according to the logic of the machine not where the M Code is in the block of code. So if you put your M Code at the front of a block of code. The other thing to note with M Codes is that it makes no difference where they are in a block of code. You wouldn’t even get an alarm on most controls and it may just obey the first M Code it sees and ignore the last one. So you could get some crazy shit happening. The first one in the block usually wins but I can’t guarantee it. There are exceptions to this rule, M Codes that is, but please don’t overload yourself with this at the moment. Please note no animals were hurt in the making of this post. If they are then they will fight to the death. With M codes they hate being on the same line of code. Snow Leopards only ever get together to mate, they don’t even have a Christmas party or get pissed on a stag night. M codes are the Snow Leopards of CNC Machining Snow Leopards are Solitary Animals You could be wasting memory space or wearing out the tips of your fingers. You don’t need the extra zero so I advise you leave it out, program M3 M4 M5. Sometimes known as miscellaneous functions.Ī typical M Code would be M03 which would start your spindle forwards.

M Codes are used to turn things on and off on a CNC Lathe. That’s because you don’t actually need many. This is my list of CNC Turning M Codes and you will notice there aren’t many.
