DIY Home Made 5-Axis CNC To Fusion 360

[Anonymous]

Hey, there all I googled how to get custom CNC machines into Fusion 360 and haven't found a lot of useful information on how to get my DIY CNC into fusion 360 and test it to see if it's working. 

I got everything moving in Mach3Mill I just don't know how to get the other two axes A and B working with my design in Fusion 360.

I'm sure getting my reference model into Fusion should be easy I don't know how to get the cutting action to work with my machine. I'm not worried about getting my reference model into fusion, I need to know how to get movement cutting actions like rotations of axis A and B included in relation to how my machine moves.

Got your G-Code "4404.nc" running, just needed to make it a .tap file.
Also, the A-Axis moved! very promising.

Ouch, you should have put a small block on the table and touched off on it and then added a 100mm or so to the Z height and taken the tool out, always "cut some air" with a new program and a new machine !!

Ah, apologies, I am used to using .nc file as I now use Mach4, I just keep the Mach3 for testing for others like yourself 🙂

Well, it is obviously running OK, you just need to be much more careful with your setting up of stock and Part and Tool Offsets with the 5 axis but if you do it right it does become quite easy after the first thousand or so attempts 🙂 🙂 🙂

Before you run any more code you need to take a step back and get your machine setup correctly, looking at you video when I actually got it to run all the way through I see there are a few things that need attention before running it again.

First, you only appear to have 4 axis enabled and the A axis is wrongly assigned, the A axis should be the one that lifts the trunnion up -90 and +90 degrees, the plate that you would fix your stock to ie the White circular plate is the C axis, you need to get them correctly set up before doing anything else, that was the reason for your collision.

So get those A and C axis properly set up and do some simple test moves using the MDI function at slow speeds !!

we will get there eventually.

Also, I don't have a C Stepper motor controller port, or do I need to slave C to B or vise versa.

You appear to be using the wrong Post Processor, look at the image below for clarification. I will attach the correct PP again for you, make sure this is the one you select 🙂

Also check the box at the bottom left to get the posted code to automatically open in your code Editor.

Regarding the use of .nc files, you should be able to load them to Mach3 the same as a .tap file, using the same 6 axis Screen as you I can load .nc files no problem.

What motion controller are you using ? Does it have 5 or more actual motor outputs? If so what are they designated as ? Photos of it ??

The motor for bottom plate axis should be connected to the C axis output and the motor that swings up to the rear and front should be connected to the A axis output for it to all work correctly.

If you only have A and B outputs then the Post Processor will need to be modified (Again !!) to output code with A and B moves instead of A and C as it is now.

So, I have attached two Post Processors that may work for you depending on your actual physical outputs from your Motion Control unit. These will in all probability need some small adjustments but need to be tested thoroughly first !!

Yep, that looks like it worked. Thanks for all your help now i just need to line everything up and calibrate it.

Excellent work 🙂 looks good 🙂

Yes, now go through every little detail and you should have a nice little setup there 🙂

Be nice if you could do a video later of it cutting something for the Community to see what a good job you did 🙂 🙂 🙂

Enjoy it !!!

Stay Safe

I got all 5 axes moving but I cant create a post poses without it stabbing my stock, and when I try to create a post poses with Safe Rretacts set to clearance height.

The red lines show the z-axis plunging through the stock.
