[CLOSED] GRBL and Fusion 360

[Tom.Hemans]

Hi Fusion 360 community!

We're looking for feedback from people using Fusion 360 with GRBL software and how these products have been integrated into your workflows.

• What CNC machines are you driving and what kind of operations are you doing?
• Are you using a G-code sender? If so, which one?
• What post processor are you using? One from the Post Library, one that you've modified yourself or one from another source?

Looking forward to hearing from you all and starting a discussion.

Hi @Tom.Hemans , got your message :). I am happy to assist, here are my answers:

---

• What CNC machines are you driving and what kind of operations are you doing?

---

I am using a X-Carve 750. It is outfitted with both a router cutting head as well as a low power (5W) laser head.

I've used the machine to do milling and engravings in wood, MDF, plywood, aluminium, acrylic. The laser is useful for cutting templates on cardboard or paper and also to engrave or burn onto the materials listed above. Sometimes in my workflow I need to mix the two. I also use the machine to mill circuit boards that require fine detail.

• Are you using a G-code sender? If so, which one?

---

I use CNCjs as the sender for the milling and laser jobs. However for the circuit boards I use bCNC.

---

What post processor are you using? One from the Post Library, one that you've modified yourself or one from another source?

---

I started with the GRBL post processor indicated by Inventables, the makers of the X-Carve. However I later found that Autodesk had a repository for the post processors and I grabbed the one on there that had been modified to drive a laser head. Since then I have modified both to allow for better flexibility in my workflow and to interact better with the senders I am using, especially when I need to mix the milling with the laser.

Hope this helps, feel free to ask more questions. I am hoping I can learn enough about the post processor to add some enhancements to mine.

Thanks @mellamanjefe, this is great information!

Hi Tom,

I am new to Fusion 360 and to CNC.

I have a BobsCNC Evolution 4 machine which runs GRBL 1.1.

I'm using Universal G-Code Sender on a MacBook Air.

I got the latest GRBL Post file from the Post Library.

I'm just getting started, but I already ran into an issue between Fusion 360 Post Processing and GRBL.

I'm doing a 3D Adaptive Clearing operation which generates the following lines of G-Code:

G3 X5.196 Y2.3619 I0.0069 J0.0244
X5.176 Y2.4114 I-0.0106 J0.0244. <=== This line causes GRBL to return an Error 33.

[Error] An error was detected while sending 'X5.176Y2.4114I-0.0106J0.0244': (error:33) Motion command target is invalid. Streaming has been paused.
**** The communicator has been paused ****

My understanding is that this is because GRBL is error checking the ARC command (G3) and the math is not matching up.

Any suggestions for how best to fix this?

I'm only getting one of these errors in the G-Code file.

regards,

Bob Greenberg

Hi!

I've made my first steps in CAM/CNC and it's CNC3018 Pro - veeeery popular GRBL-powered entry level aliexpress-sourced hobbyist cnc machine.

I use pre-installed grbl post and UGCS to drive it.

Thanks for the feedback @pavmed

Thanks for the feedback @Anonymous, regarding the error I'd have to see the whole NC code/machine manual to have a better idea, but I would guess the arc is out of tolerance. If you modify the (Built-in) Tolerance Property in the Post Process dialog, this may fix the error.

Hi

I have a LEAD CNC 1010 machine from Openbuild

I am using the GRBL post processor recommended in Openbuilds forum (seems the one in Fusion sucks but sure it will evolve positively 😞 https://github.com/swarfer/GRBL-Post-Processor

As a GCode sender, I am currently staying with Openbuilds Control software. In any case, I am probably not alone having an old PC to connect to my CNC so not sure I am willing to use Fusion 360 in there (=better to have a light GCode sender)

hope it helps

Hi Tom, I'm using a custom retrofitted 3 axis milling machine, used especially right now for precision machining of machinable wax with down to 1/64" endmills to get very good results for resin casting for inventions.  I actually use Repetier Host, which is supposedly more for 3d printers but works pretty good with easy configuration generation, and a post processor I found awhile back for Repetier and which those in the CAM forum were kind enough to tweak. 

Amazing what Fusion 360 and a cheap but capable CNC machine can accomplish!

Nice to see interest in GRBL and Fusion 360.

• What CNC machines are you driving and what kind of operations are you doing?
  
  The CNC machine I am using GRBL with is home built, my very first attempt in doing so, it's about 5 years old now. She is not very rigid, but I learned a lot with it.
  
  I am mostly using it for wood parts, but I did cut some aluminum too.
  
  
• Are you using a G-code sender? If so, which one?
  
  Both bCNC and CNCjs. Nowadays I tend to use CNCJs more, as it's macro system seems more stable.
  
  
• What post processor are you using? One from the Post Library, one that you've modified yourself or one from another source?
  
  I am using the last post from the Post Library, but I started to modify one to be able to use a "poor boy" self made (3D printed) Renishaw kind of probe. It's not done yet.

Hii All,

I am using Fusion For CNC MAchine Like GRBL For GCODE Generation.

I make my own DIY CNC using Arduino shield and use GCode Sender for CNC Machining.

For Laser, I am using a laser Grbl for sending data.

Post Processor is GRBL and  .NC Extension.
