Click on each link below to see what parts I suggest. I have only added products that are easy to find. The price may be more expensive as most of it is from amazon which is available in every country. If you want to bargain there are also Temu and Aliexpress as examples. Prices change regularly and can exceed the 500 Eur or USD that the machine costs to build.
I am also not responsible if I refer to the wrong product or if you happen to buy the wrong one. I have no responsibility whatsoever regarding this project, this is entirely up to you. We do not have any support at all for this machine. If you have questions you can ask them in the comment section under the inventive video.
UPDATE! Previously I have used Arduino with CNCshield as electronics just as I mention in the video. The software Estlcam has stopped supporting that electronics so you have to go back to version 10 if you want to be able to use that electronics. Another alternative is to use Arduino Mega260 see video example here: https://youtu.be/DFU-zd2rKJA?si=qeX8bjQSb7qmBbE6. CNC electronics is a jungle and there are countless of alternatives…
We build the machine with Arduino and CNC shield. This works but is not optimal. We recommend that you read a little more about GRBL control electronics for cnc machines with Nema23 motors. There are a lot of different solutions. For example, search for “grbl motion controller” or look at Open builds GRBL solutions https://us.openbuilds.com/BlackBox-Motion-Control-System-X32
We will have the hardware and the plates as a product. Go to the shop section to see if we have uploaded them, if not they are comming soon.
Note that when i refere to a Amazon product, it will take you to your country and that product may not be avalible where you are. But all this are pretty standard products and should be easy to find.
