- เผยแพร่เมื่อ 24 ส.ค. 2011
- Milling machine CNC conversion built around an GRBLshield from Synthetos.com. The GRBLshield is an Arduino shield that can drive three bipolar stepper motors up to 2.5 amps per phase, and contains an open source G-code interpreter called GRBL.
Stream G-code over USB to the GRBLshield, and you're in business. - วิทยาศาสตร์และเทคโนโลยี

Great work my friend. Not only were you complete in your explanation of what it was you were showing your viewer but you coding and approach was very easy to follow and clean. Thank you for sharing.
Very well done. It's obvious you gave everything a lot of thought and executed it perfectly. I think you, Sir, are able to achieve anything you set your mind to. Much respect.
Amazing way of converting regular mill into CNC, thank you for this video
Hmmm. I hadn't considered converting my milling machine to CNC..... until now. Very interesting and pleasantly presented. Many thanks for posting!
Excellent video and impressive work on the conversion - very well thought out
Wow very nice John! I need one of those! Next Arduino project!
Well, that was the most fun ive had whilst being made to feel very very stupid!
Thanks for the post.
wow! I hope your kids know how lucky they are!
You've inspired me. Thanks!
Really nice work and simple explanation of the CNC process. *thumbs up*
Awesome ... You must be an expert software and mechanical engineer
That is a fabulous mod! Very cool!
Great video. Thanks for posting.
I have a very similar mill. Do you have a full parts list and do you have any drawings of the brackets you made to mount the steppers? Thank you.
I'd like to see a set up and build tutorial on the machine if you can, thank you, and great job on the set up!
Nice build !
So very cool. I'm looking forward to following your lead with my new X3 once I get used to it as it is. Like you, I plan to retain the ability to use it manually. I'm surprised that I don't see any sliding digital position indicators. I guess you are better at counting turns than I am. :-)
Me like! :)
I'm going to build something similar. Got all the parts, just the mill that's missing.
I have the same mill, what did you do to improve backlash on the table? I'd like to see a set up and build tutorial on the machine if you can. thank you, and great job on the set up!
how did you manage to cope with the backlash?
Man you rocks, Thanks for this video.
Thanks! great work
Olá amigo excelente trabalho, meus parabéns. 👍
Great video, I'm converting my mill as well and it appears to be the same size. What size stepper motors did you use and what was the gear ratio you used for the timing belts?
Very Comprehensive and intuitive . Please distribute this knowledge it is Light and Let there be light

Well done.
get an A or A plus in my book, nice work !
Nice job and nice video. Did you replace the lead screws with ball screws on your mill?
nicely done
Great video, where did you source the pulleys and belts? thanks
Amazing. Im brining home a jet jmd15 and wanted to know if you had more info on your build? Ball screws or just stock, etc? Amazing work!
"I haven't replaced the lead screws and they do have backlash. I carefully measured the backlash and compensate for it in software when I have direction changes. Seems to work well for me."
From down a bit
So, quick question.. Can you outline or just take some really awesome pictures of how you have the motors attached to the x y and z axis?
Nice work mate. Have you found any drawbacks from using the grblshield? such as no backlash compensation? Also, did you have to set the steps per mm/inch? and how did you find setting up the part and zeroing the XYZ axis? is it an easy process?
Very helpfull. THANKS

hi i have arduino uno and driver L293D how i wiring output of arduino to stepper moteur bipolaire and thanks
This is helpfull, thanx :D
Very nice. Are there programs available to run the mill with out knowing python or programing? I have mach3 but will it talk to the shield or in some way connect so as to run the mill? Sorry if I am not clear. I have Mach3- I have Cad- now to learn how to connect it to a mill. Suggestions?
Thanks
Excellent! Can you tell me about the inside parts ? The Ball screws, Nuts, etc...? Where did you get them?
Your RF-30 looks alot like my PDM-30 any advice on converting my mill to cnc? Did you switch to ballscrews? What was your motor size? Thanks!
Impressive! What are you using to do your modeling? Either way very very cool!
Very nice machine! Out of curiosity, have you figured out what would be accuracy and repeatability of your system?
good work
hello. could you help me and tell me which parts should i get and need to do that. i have a milling machine similar to yours but i dont know what i need to do it cnc and what programs do i need on my computer to use it
Nice video! Where did you get the power supply? (is it salvaged from some other device or you bought it as it is?)
What are the specs of the stepper motors used.. can you help me with some reference regarding selecting the same for machines.
Good job!!! man
Really good staff man, one question about the python script is it taken from the LinuxCNC project or you've done it by your self
where did you source the pulleys and belts? thanks
Hi there, may I ask what size motors did you use and how long did they last. Thanks
Hi - is this shield still available commercially? Also how is your going reliability wise? Great project - to finish with :D
What kind of motor and transmissions do you use? And what are the specifications of your stepper motor?
How did you know 2.5 amps would be enough? Also, do you have feedback if you overdrive the motor and slip a step? Thanks
How do you set the #steps/rev and the lead on the drive screws etc? Does grbl do that automatically?
I'm in the process of a CNC conversion and I'm just using L297/L298 motor drivers...I had no idea that grblShield existed. What inputs are used on that shield? Is there a serial interface on the grbl, or does it just use the standard enable, dir, full/half, dir,step, etc...? If I could use that grblShield without many drastic changes to my circuit, that would be awesome. Cool video as well, by the way.
very nice, did you develop the CAM to G-code python by yourself>?
Does your python script handle tool offset as well? Any reason why you can't use a commercial option such as Cut2D or Vcarve for your CAM portion? Also how streamline was your conversion in the programming department? I have been looking to drive a homemade plotter from printer parts that I will later convert to a full size router with the same drivers but I am not currently very experienced with arduinos. Especially with many options like, RAMPS Pololu, Sparkfun EasyDrivers, Sanguinololu etc...
nice case
Is this machine good for steel cutting
Great job!
I have the same mill with the steppers already installed. I just bought an UNO Adruino. Is there any way you can help me by sharing your code and some of your knowledge?
how precise were your cuts?
Do you have much back lash in your lead screws?
Wow, that is genius! How much do one of those mills run for? This would be an excellent alternative to building a cnc router from scratch, great work!
both harbour freight and grizzly tools sell this machine. check out their web sites. its not quite a full size machine. it has about a 10 inch z travel but the head can be moved up and down to accommodate different projects. its quill bearings arn't made for long durration hard use (gets hot after an hour or so) but overall its a wonderfull machine I have done some really heavy and cool stuff with mine. expect to change the acme screws for ball screws. the ways are ROCK SOLID. I really love the way he mounted the motors. I want to know how he did the z access and if he has any cad files for the conversion parts. I'll have to mill them on the same machine as I install them on.
I noticed you were using a mac. Is there any other "user friendly" software out there for Mac. What you showed was pretty involved to say the least. I have been looking into getting a windows machine so I can run "easier" software. Is there anything out there for Mac that would be similar to running mach 3, cambam, or using sketchup for the drawing software. Thanks.
Cool video man. The python script you wrote to convert the .obj file to G-code. How did you go about that?
Very cool video, and what you did is very cool. I do have to wonder though wouldn't it be cheaper and easier to get a cheapo CNC kit from ebay (~200) for steppers, power supply and BOB, a copy of heeks cam (free), and a copy of CNC linux (also free). Did you do it this way just to learn how to do it from scratch?
How did the whole setup "know" where exactly the piece of metal was? (Did you put the thing in an exact position?
Do you have the reference of the stepper motors?
What size motor did you use here? how many Nm??
What was the donor machine you used?
Is the python script to convert the cad file to g-code available online? If so, where may I find it? Thanks.
what kind of steppers was that? nema 17, 23, 34?
make/model of the milling machine?
Brilliant guy :). I would have a question to the general public knowing a little bit more about CNC than me. Mainly, my question is : What parts can you make at home to earn money thanks to CNC machining (While having for example a CNC converted 2 axis Lathe and a CNC converted 3 or 4 axis Milling Machine) ? I'm just beginning and I was curious if ever my hobby can bring me some income ;). Kind Regards !
Thx :)
i want NEMA34 MOTORS HOW I CAN RUN ON ARDUINO SHIELD
great ....
awesome .....may you please share the python script i want to see where i can edit to control 6 axis cnc or if you know of the script which one can use please share
you should try making printed circuit boards with this.
is it possible you share the python script?? i'm trying to make drills with the arduino/grblshield but i can't do it, because the G81 isn't supported it....
Thanks in advance..
Just watching that machine made me like and subscribe.I recently purchased a mini mill myself and have all the adaptors ready for the CNC conversion but untill then its good old conventional milling for me. lol Who knows you might even check out my playlist on hobby machining and like and subscribe yourself. great vid keep up the good work
Bad ass
you are fucking genius
where can I get the same case as yours?
Yes,I want to ask the same question,can u tell us?
Dear Hadley,
At the outset, thanks for an informative video. I think yours is the most detailed wrt the GRBL shield.
I am trying to make my own CNC (DIY type).I have made the frame, bought three NEMA 17, power supply almost similar to the one in this video, a GRBL shield and seeduino bundle from Synthetos. I need some help to put it all together. I am using Windows X
and Arduino IDE. Shall be grateful if you can provide your email id for me to put forth my queries. Regards
Please Give the price for machine
both harbour freight and grizzly tools sell this machine. check out their web sites. its not quite a full size machine. it has about a 10 inch z travel but the head can be moved up and down to accommodate different projects.
Excellent video, you are very intelligent! Please though, please stop smacking your lips.
Title promises a CNC conversion; I'm 7 minutes in and now, finally, I see a milling machine. Can't take any more; moving on to other videos
Painfully dragging and very low volume. Please redo the audio with more life and volume.
Do you have the reference of the stepper motors?
great...
