Work Coordinate Systems can be confusing. So take a moment to learn about why they are the way they are.

If life were simple, there would only be 1 Work Coordinate System, and I would use it all the time. And I would never let you, or anyone else use my precious equipment, because I would worry too much that your work would crash into my work.

But life isn’t this simple. There are a lot of us using the same equipment (the Haas Super Mini Mill) so let’s make it possible for each of us to have a Work Coordinate System to call our own.

Take a look at my WCS (my Work Coordinate System). In Fusion, for every CAM setup I make (as Daniel Houghton), I’ll enter 86 as my WCS…

 

…so that when I post my gCode I activate the G154 P80 work coordinate system on the Haas Super Mini Mill.

 

So 86 in Fusion becomes G154P80 on the Haas Super Mini Mill. Weird.

Why are there two, seemingly arbitrary, numbers to memorize here? Well, we are coordinating between software and hardware. Each of us is using Fusion as our software and the Haas Super Mini Mill as our hardware.

Ok. But why didn’t they make the numbers the same? Why didn’t they make it so that 86 in Fusion generates 86 in gCode? Wouldn’t that make it easier to coordinate? Well, we are coordinating between software and hardware, and there are lots of different hardware manufacturers in the world. Haas is one of them. And Haas dedicated a portion of the controller memory to 6 Work Coordinate Systems: G54, G55, G56, G57, G58 and G59.

And at that moment in time they thought, that’s plenty! Who would ever need more than 6 Work Coordinate Systems? Who would ever teach a class with more than 6 people in it? But the world of manufacturing continued to evolve. And its evolution became more complicated. And with those complications came the need for even more than 6 work coordinate systems. But where in memory should they go? G60 would be the logical next spot, but G60 was already claimed in controller memory. And so was G61, G62, G63 and so on…

So the designers carved out an additional block of memory in the next spot where there was room for LOTS of work coordinate systems, and the memory that was available at that moment was G154. And at that moment in history it seemed that 99 additional work coordinate systems would be enough. So 99 memory slots were set aside for this purpose, and they were called G154 P1, G154 P2, G154 P3 and so on up to G154 P99.
