- I engrave some wooden plant labels using Fusion360, Candle and a Sainsmart Genmitsu 4030
This would work equally well on a 3018 style machine
Ideal beginner project/exercise to begin to understand Fusion, CNC, G-code etc.
For a real beginner Fusion360 tutorial, please check out Foxberg's Fabbercobblin...

G-code I used to set G54 on my machine
G10 G54 P1 L2 X-383 Y-171 Z-44
G10 = set offset command
G54 = specific work offset location
P1 = parameter address (P1 is associated with G54 I think!)
L2 = informs G10 we are setting work offsets (as opposed to tool offsets)
I don't fully understand the syntax above, so use it with care.
Always test your g-code at a safe Z height before committing tool to material
....even if it is wood! I broke a 3mm end mill by not doing this.

Very clever. Thank you for inviting us into your shop.
Thanks for the Fusion update. I was just playing with embedding.
All the best
Dan.
Hi Dan. I hope it was helpful.
Thank you for doing this, hard to find somebody on youtube that actually going through all this using fusion 360 and this machine. Also, please dont delete this video, I would like to come back here again someday if i end up forgetting everything.
No problem, I'm glad it was helpful. No plans to delete any videos, so it'll be here should you need it again. Thanks for watching.
@@ollysworkshop I want to use fusion 360 with genmitsu cnc but it kept running into so many problems. Do you know why the z axis of the spindle keep raising up to hit limit whenever I hit send to start?
@@SkyfalconTin hi, I don't know why it's doing that, but it should be possible to work out why. First take a look at the first few gcodes and work out what the program is asking the machine to do. Just Google the G codes, that's what I do. You may have to adjust some of the grbl settings, perhaps an axis is reversed or something. I seem to remember I had to fiddle with some of the grbl settings on my 3018 machine to get it to behave the same as the 4030. Let me know how you get on. Thanks
@@ollysworkshop Thanks for the help, I found the answer online on Fusion Q&A. I finally got it to run and learn a few things. Hopefully it didnt break and possibly, i need to build an enclosure because this machine is too loud, are they always noisy?
@@SkyfalconTin yes, unfortunately they are noisy. Glad you found your answer. Best of luck.
Well done Olly, to say you are just learning, you have a pretty good grasp of the CAD / CAM landscape. Spent years doing this stuff in industry and worked alongside a few so called professionals in the trade who would have struggled to explain the process as you just did. Keep going, you will learn new stuff every time you use it! Cheers, Jon
Hi Jon. I think it's a case of the more you know, the more you realise you don't know! Thanks for the vote of confidence.
Great job. This is very interesting, we have been thinking of getting one of these machines. It is good to watch how you did this, thanks for sharing
Thanks Joseph. I'm glad you found it interesting. Let me know if you would like me to cover any other aspects. I skipped over a lot of fundamentals.
Gday Olly, very well explained, one day I might understand how all the code works, thanks for sharing mate, cheers
Thanks Matty. It's a pretty steep learning curve to begin with, there's a lot of things that you have to get right before it all comes together. I've done my usual and just kept at it until I got a result, then tried to understand what it was I actually did to get there!
Thanks for the nice how-to mate.
Hope it was useful. Thanks for the comment!👍
great video thanks loads. explained perfectly cheers. now i need a cnc... one day i think :)
It's a slippery slope Julian. I've just seen the Langmuir MR1 (I think) and want one, but they don't ship to the UK ☹️
Well done. Thanks!
No probs, hope that gave you an idea of the process.
Thanks Olly! I keep toying with the idea of getting one of those small machines to play with, but the learning curve looks almost vertical!
It is!
See my response to Matty's workshop.
You can get the basic 3018 type machine for very little now. That's how I got started. Not enough power to do any damage, but capable enough to do some basic work on. The worst bit is getting your head round all the half a billion settings in Fusion!
Hello Olly,
Great explanation, I am starting to think an old chap like me could do with some practice...
Take care.
Paul,,
Hi Paul. Definitely a good skill to have, but as others have said, the learning curve is pretty steep. Thanks for watching.
Helpful!! Thanks!!
Glad it was useful. Thanks for watching.
Hi Olly
If your only just learning i don't know where that puts me in my old school ways, i would love to give it a go though, great explanation but a bit complicated for such as me with zero experience! You could maybe do an episode for dummies or is this it🙌
Take Care and see you next time
Kev
Hi Kev. There was some assumed knowledge, necessary as the video would have got very long without it. Foxberg's Fabbercobblin' has done a few Fusion 360 for dummies videos if you're interested. Thanks for watching!
@@ollysworkshop cheers olly i will take a look🤔👍👍
Nice !!!
Thanks!
Great Video, how do you get the SainSmart machine and Grbl options as the machine doesn’t seem to be in the list of machines. Thanks in advance. Phil
Hi, thanks for your question. I made a video on this as someone else asked me the same thing. czcams.com/video/2WuyqSDvGzw/video.html
Where did you get the profile for the Sainsmart 3018? I have a 3020 Pro max but cannot locate any machines via Fusion 360 library
Hi David, use the same method as shown in the video. Find the Autodesk 'generic' machines, copy an appropriate one to your library and modify the parameters to meet your machine. Thanks for the question.
Im suffering the very same issue with a similar model. What i dont understand is why you jog to that random position that is not even touching the stock
Hi, I'm not sure what you are referring to? Can you be a bit more specific, a time index from the video would be ideal. Let me know and I'll do my best to answer your question. Thanks for watching and your comment.
hi @ollysworkshop In conjunction with your Fusion 360 profile video and this one, how much are applicable to the Genmitsu 4040-Pro? I'm having a hard time getting Easel-made GCode to run properly on Candle, so I'm going to try Fusion 360
Hi. Everything I covered in the video should be applicable, the only difference being the machine dimensions, but I'm not sure how critical that is unless you are pushing the limits. What issues are you running into with candle?
Where did you get your machine profile that you have set up in fusion 360. They don't have the machine in the library and i cant find a profile anywhere to import. Could you provide an export of yours? Great videos BTW!!
Hi Roger. There was a fair bit of assumed knowledge in the video, so thanks for the question. I did find a suitable machine profile in Fusion, but it was a generic one that I had to edit the parameters of. The grbl post processor is built in with no need to modify. Let me know if you would like a video explaining the process of setting it all up. Thanks for watching.
@@ollysworkshop Yeah that would be amazing. The CAD part of Fusion i have sort of figured out but the machining part is another beast. If you could do a step by step idiots guide to setting up the 4030 as a machine in fusion that would be amazing, i looked at some of the generic profiles but couldn't see the best place to start. If you have something that's working it would be much appreciated.
@@fistandanti1us no problem, I'll try and get something done in the next few weeks.
@Roger Mills Sorry for the delay, I have finally produced a video for you. Let me know if there's anything else you want to know.
@@ollysworkshop awesome you are the best!
Hi, would you have any idea why after exporting as gbrl g code and running my machine in Candle, my 4030 decides (it seems at random) to randomly cut a straight line across my work. Im sure it has to be in the G-Code because I've tried different laptops and many different tooling operations and it happens on all of them.
Hi. Only thing I can immediately think of without knowing any more is check that the Z zero is set to the same point as in the CAM (usually the top surface), and that the retract and safe heights are set appropriately. Also check that Z is driving in the correct direction. I had an issue where the head plunged deep into the work instead of retracting!😬
Hi thanks for that. The solution in the end was the offline screen. If it was plugged into the controller at the same time as a laptop/PC it would send random error messages or blips to the machine during an operation. After unplugging that I’ve had no issues.
@@toby-cass thanks for the update. That's good to know.
Can Candle add a drilling function thx
Hi, candle is a gcode sending program, it will do exactly what you tell it to do. You need to create the appropriate gcode for drilling in the same way as you create the milling gcode. I have successfully used both flatCAM and fusion360 to generate drilling gcode which can then be opened and run in candle. Hope this helps.
@@ollysworkshop Thx! Helped
Hrm how did you set up the machine for the 4030? its not showing in the list on my fusion 360
Found it! For anyone wondering: czcams.com/video/2WuyqSDvGzw/video.html
You beat me to it! Hope it makes sense and it's not changed since I made it. Autodesk have a habit of changing things.
Its changed a little but its easy enough to understand what the basics I need to set are. Cheers.@@ollysworkshop
Hi, it may be a silly question but
Is it possible to import .gcode extension with fusion 360?
My machine does not recognize .nc
Or how to convert .nc to .gcode extension?
Hi. As far as I know, as long as the file actually contains g code, you can give it whatever extension you like. I would just try renaming the file in Windows explorer (assuming you are using windows) with the .gcode extension. I will have a look later to see if it's possible to change the output extension in the post screen. Thanks for your question.
@@ollysworkshop hello,
Unfortunately I tried that, it doesn't work.
I have one Creality cp-01, for CNC part
It wants .gcode. If you learn a solution, I would be very grateful if you could share it with me. thank you
Hi, sorry for the delay. Just had a look and you need to select the correct Post in the post screen (use choose from library option). I have tried selecting Creality Family and it automatically changes the extension to .gcode.
Check out this linear rail kit: czcams.com/video/5312HYIQHAM/video.html
Looks great. I would love to review the kit if you have a spare one going? 😜
@@ollysworkshop I would be happy to have you review I am just finalizing testing to settle on finale design,
No worries, that sounds great. Just let me know when you are ready. You can find my email address on the about tab of my channel page (on a desktop, doesn't work on mobile)
