Is there an option on the import for metric units? If so, try turning it off (or on) and see if that helps
| | |
I have just finished building a CNC machine. Mechanically t works wvery well. I have downloaded the Mach3 demo software which is also working as it should.
Howeve, I have a problem with G-Code files. I have drawn a template (45 mm square with four 4mm holes at each corner) with CorrelDraw ver.8 and saved as a plt file. When I load this into Mach3, the G-Code produced is dimensionally wrong!. The X and Y values are in the order of 1 or 2 units. Shouldn't it be 45 as I have drawn it?and cut I get a small movements in the X and Y axes. It isn't the machine, for when I manually enter a G-code instruction it works fine. For example, if I enter "G0 X50" the X axis will move 50mm.
Can someone throw some light on this matter. I have absolutely no knowledge of G-Code programming. Thanking you all in advance

Try using a (DXF) File
is there an option on scale that maybe turned on?
Post your g-code file here
Try this file if it dont work Mach3 is set up wrong. if it works CorrelDraw plt file is wrong.
Thank you to everyone for coming to my rescue. I have imported Motomitch's file and it work as it should. I noticed that G-Code genrated from his file gave a X and Y value of 45. With my file it gave a value of 2.2 for a value that should be 45. The fact that Motomitch's file generated the correct value must mean that the scaling was not on.
Thinking that maybe the dfx file I generated was incorrect, I used DeskEngrave to create three letters (ABC) at 72 pts, which translate to 25.4mm in height. Imported it in Mach3 and yet again the G-Code was wrong! So where did I go wrong ?
Thanks again to all the help
Post the .dxf and we can see what size the .dxf is.

Sorry Switcher, I was going to say in my earlier reply that I am not able to sendng to the G-Code file. In a hurry to response to everyone's help I forget to mention it.
Being wrong I deleted it, if you think that the G-Code may throw some light I would be happy to re-generate it and sent it on.
Thanks

Go ahead and post your g-code , couldn't hurt anything, we'll have a look at it.
Here are the files for my 45mm square. Thanks for the help
Jock
Don't know why G-Code didn't get sent. Here it is-
Switcher, if you look at it you will find the X and Y values are way out.
I imported the dfx file into Mach3 and generated the code. Juat as I did with Motomitch's dfx, except his came out right.
