    Raspberry Pi Alamode CNC Controller

    Lately I have been working on my 3D printer and I do not currently have a video of my CNC machine working because it has not worked for some time. We have moved three times in the past three years. I am now working on getting my CNC machine working again. Part of the reason that I started building my CNC controller was that I was not happy about the precision and repeatability of my little machine. I bought new lead screws and anti-backlash nuts and started modifying my machine. It turned out that doing the modifications to my machine was more difficult than I had anticipated and took a long time. I am now making good progress finishing those modifications. I have printed some new mounting components on my 3D printer that are allowing me to get things done now that I had a lot of...

    Lately I have been working on my 3D printer and I do not currently have a video of my CNC machine working because it has not worked for some time. We have moved three times in the past three years. I am now working on getting my CNC machine working again. Part of the reason that I started building my CNC controller was that I was not happy about the precision and repeatability of my little machine. I bought new lead screws and anti-backlash nuts and started modifying my machine. It turned out that doing the modifications to my machine was more difficult than I had anticipated and took a long time. I am now making good progress finishing those modifications. I have printed some new mounting components on my 3D printer that are allowing me to get things done now that I had a lot of trouble doing previously. Hopefully, I will finish things up in the next week or so. Then I could make a video of my machine working but it is not working right now and is in many pieces.You concern with precision and repeatability is the most important aspect of a machine tool, in my opinion. I can tell you this. Leadscrews are more precise than belts, in general, as belts will occasionally slip and result in missed steps. However, my CNC machine had cheap threaded rods. So I did not have that problem. I instead I had a problem with precision and repeatability because the threads were not precision cut. Thus, I replaced the threaded rods with precision lead screws. Also, the anti-backlash mechanisms were not that good and they were replaced with the leadscrews and matching anti-backlash nuts. Further, my original stepper motors were connected to the threaded rods with plastic tubing that didn't work very well and I replaced the tubing with aluminum couplers.The precision and repeatability is not a big factor of the software, it is very accurate. Precision and repeatability is more determined by physical factors of the machine itself. Precision of the leadscrews and anti-backlash nuts, stepping or micro-stepping of the stepper motors, torque and holding capacity of the stepper motors, smoothness of the slide bearings, stability of the machine, orthogonality of the axes, vibration, runout or how much the spindle's bit moves from perfectly straight, etc.Take a look at the new CNC board from Protoneer. It will make the project a bit cheaper and easier to do (you would not need the Alamode board). If you are interested in the precision and repeatability of the software take a look at the GRBL site on Github. Lastly, read through the comments here. you will find a lot of great information about CNC machines.

    3D Printed Lathe

    Excellent Instructible! The only things that I would do differently is use crimp on connectors for all of the wires and put some sort of cover over the gears and motors. if I build one of these I will make those changes. Very well done. You can add technical writing to the list of things you have learned from this project. You get my vote for sure and yoy should easily get the grade too.

    No problem at all. I thought that it was kind of funny that mentioned that I could be employeed as technical writer, as I had actually been one for many years. Thanks for helping me to feel a bit younger than I am.

    Raspberry Pi Alamode CNC Controller

    Thanks for the kind words. I am now 66 and have been tinkering for a long time. I am a disabled Viet Nam veteran and fully retired now. I actually did work as a technical writer for a few years and in my last job, before I retired, I worked as a Test Program Engineer and wrote test plans and test procedures for sophisticated electronic systems. I also designed and built prototype electronic test equipment and fixtures and mentored more junior associates. I don't really think that I ironed out every instance where there could have been some misunderstanding but I think my write up is pretty good. I never thought that it would get as many views as it has. When I look at the number of views it always surprises me. I tried to enter it in a contest but was not allowed to as I submitt...

I tried to enter it in a contest but was not allowed to as I submitted it a couple of days before the contest started. I would have really liked to have won a laser engraver but I still feel pretty good about it just due to the number of people who have read it, tried it, and made comments about it. I recently purchased a 3D printer from a Chinese place and I am enjoying learning about it. Maybe I will write another instructable about that someday. Thanks again for reading my 'able and your comments.

    Raspberry Pi Alamode CNC Controller

    I am sorry, but I do not use LinuxCNC at all. I am using the Grbl Controller software on my RPi and the Grbl firmware on my Alamode/Arduino. I am not aware that LinuxCNC can be run on a RPi at this time. At least, I have never tried to do that. I am not sure that LinuxCNC would run very well on an RPi either. perhaps someone else has done it and maybe give you more positive feedback. Check out the liinks in my write up and you should be able to get Grbl working pretty quickly (if you are familiar with Linux/Unix). Good luck.

    Raspberry Pi Alamode CNC Controller

    If you built a system like mine then you should be able to test your theory to see if it works - I am able to connect wirelessly to my RPi, transfer files, start Grbl and connect to the Arduino (Alamode) and then set up the machines and eventually start making the part. I can disconnect from my RPi at any time and reconnect at any time. I am not sure as to how to answer your request. There are newer versions of the Grbl code that you might be interested in on the GitHub Grbl site here:https://github.com/grbl/grblThe code for the Alamode is available from the WyoLum site here: http://wyolum.com/projects/alamode/How to setup the Grbl code is available from the Protoneer site here:http://blog.protoneer.co.nz/arduino-cnc-shield/ I like the new CNC hat from Protoneer that works with the ...

They, Protoneer, also have a link to download their own customized version of the software for the RPi (includes everything you need on the RPi already installed and ready to go) with just one download. You download it and then install it on your SD/TF memory module and then boot your RPi and you are up and running. Only thing left to do it set up you wireless networking on you RPi (make sure that you get a wireless module that is known to work with the RPi to avoid a lot of frustration). Good luck, I hope I answered your questions as you needed to have them answered.

    Raspberry Pi Alamode CNC Controller

    Thanks for letting us know about that. There are many solutions out there for building a CNC controller, this certainly is not the only way to do it. It is how I did it and it works well, and I learned a lot doing it. Why not write you own instructible about what you are proposing? I am sure that others would like to see how you did it and what it looks like along the way.
