Need to turn 90 degs. was created by cwebs
I have a very large gcode in a txt. file only. I need to turn the project 90 degs. so it will fit in my machine. Can EMC2 turn it?
The project is a Mandolin top and is 14.75 inches tall (Y) and only have 14 inchs of travel in Y. Thanks Carl

You could do a global search-and-replace swapping all X to (for example) && then all Y to X, then all && to Y.

Alternatively, G10 L2 R90 will probably do what you want:

Thanks Andy, I will have to give the G10 L2 R90 a try. That would make life easyer. Thanks Carl

Gcode won't load with this G10 line. I have found some info on G68/G69 and when I can get to my machine I will try it.
Should this be supported in EMC?

What does it say?

No, the function in EMC2 G-code is handled by G10 L2.

When I tried the G10, I tried to test it in Mach3 Sim, witch I have to use on my windows computer, I got this error, P value out of range, ? There is no P. Might just be I tried it on Mach3.
I still have to get to my EMC machine and see what happens. Carl

Yes, well, that will be because Mach3 and EMC2 are different. RS274 is a rather loose "standard"
In Mach3 there is no R in a G10.
Both take a P word to specify which coordinate system is to be shifted. It might be that you need a P in both Mach3 and EMC2, or EMC2 might default to the current coordianate system if it is omitted, I am not sure.

After trying the G10 L2 R90 in EMC2 I get the same error as in Mach3, P out of range.
When using Cambam to see the cut lines over half of them are missing. However in Mach3 and EMC2 all the cut lines are shown. Mach3 shows some rapid moves that go way off the project and I think that may be the "P" problem. However, I don't know what P is for. This file is a TXT file and I don't know how to clean up the moves that don't need to be there. Text file is all I have. No DXF or anything else. Carl

Which says you probably want G10 L2 P0 R90
You could, however, set up G55 (for example) to be your rotated coordinate system, and leave it rotated permanently.
