Raspberry Pi Alamode CNC Controller
Thanks, I hope you build one too.
Your box looks great, inside and outside. Like a pro, you could sell them! Thank you so much for sharing and for giving additional information that I also will need. Very nice instructable!
A great write up. Many thanks for taking the time to compile this. Very helpful
Thank you for your quick reply with concern.I think you made it clear what I have needed. Thank you so much
It was a great help for me. I am trying to make one.I have a request and a question please.QuestionCan I disconnect my PC or Laptop from the RPi after upload the G-Code into the RPi. I don't want to monitor the process but I want to run the machine without allocating a PC for the operation continuously.RequestCan you please provide the necessary codes for the arduino and RPi.Thanks in advance.
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 newer RPi's because it does not need the Alamode functions as they are incorporated into the CNC hat (so the Alamode is not needed) and it includes an Arduino Nano that is pre-programmed with the Grbl software. 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.
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.
This is a very nice description of all the guts of a CNC controller. But if you want to dodge most of the bits and pieces to assemble this, you can buy a 4 channel CNC controller board from http://synthetos.myshopify.com/products/tinyg. It sells from their store for $129.00. It has a USB input and can be driven from most any computer using the free Chili Pepper software. You will still need fans, a power supply, case and switches etc, but going this route will result in a much more compact and complete CNC controller. If this idea has been described further down in the comments, I apologize. In addition I have no connection with Synthetos other that being a very happy customer.
You can try the ones that I mentioned in a previous comment: http://m.ebay.com/itm/110983775612?_mwBanner=1The buttons came from Adafruit.Hope that helps.
Nice work! Can I ask where you got your panel mount cable connectors? ...and buttons while we're at it.
Is it possible to just connect to the arduino through a usb cable on the pi? I already have the arduino and cnc shield set up and using my PC to control.Also, can a touch screen be used to display and control the jogging of the machine with the pi?Looks awesome!
