help needed on fusion 360 and g code
hi. I am using fusion 360 to write the g code and then downloading it to mach 3. but when I start the milling program the tool just starts to drill into the work piece. the first line of the program is
G90 G94 G91.1 G40 G49 G17
I am sorry I don't have any means to cut and paste the rest of the program. can anyone help me out. at a lost what to do.
Re: help needed on g code
The first line has nothing to do with why it's drilling into the work piece.
Also, someone needs to fix that post, as G90 and G91.1 should not be on the same line.

The MAch3 post as it stands in Fusion has some issues that I do not like either. For example it uses g91 and g91.1 that make your code be incremental and not absolute. I only noticed that it was using these as Ger's screen has a nice bar at the bottom telling what is active.
The Linxcnc post is significantly simpler and I would recommend you give that one try.

Terry just up load the txt file because without it there's nothing we can do to help.
Like the Lads say Fusion 360 Post processor is screwed up by the looks but without seeing the G-code it's impossible to tell what it's doing.
Re: help needed on g code
According to the line above, it uses G90 and G91.1.
The problem with them being on the the same line, is that if you are in G91 mode when you load the program, it won't switch to G90.

So they're not adequately supporting the most common controller software in the world?
:-D

Not sure people have actually submitted tickets to get the issues fixed. I haven't done so as I have learnt to live with it.
Re: help needed on g code
Hi.so the fault is something between the way the g code is written by fusion360 and the way mach 3 reads it. Ok but what is the fix?..
Re: help needed on g code
In the post processor option, use the linuxcnc option. Cannot remember off the top of my head how it is described.
Are you confident that you have the CAM model set up correctly? I can take a look for you if it helps. PM me your email and I will give you directions on how to do this.
