DIY Dremel CNC #3 electronics, software and firmware (Arduino, aluminium profiles, 3D printed parts)

Time to add Arduino and some other electronic components to the DIY Dremel CNC machine! We will also upload code to the Arduino (GRBL) and take a look at software to control your machine (GRBL controller and CNCjs). At the end, we will run the first tests on the machine to see how it works :)

Watch the previous parts:

I am extremely happy with how this machine works! It's super quiet and works extremely smoothly. Construction is very rigid and 3D-printed parts are okay. The first drawings are also great all lines are sharp and the dimensions are good.

What we will need, the amount in ():

Here are some of the tools:

I always wanted to have one of those fancy CNC machines that can mill metals. It's cool and it gives you so many possibilities for your next projects! I already have a few ideas for projects with a CNC machine :)

This device is not only beautiful but it does the job awesomely! Your videos gain in quality and substance Nikodem! That represents a big amount of work and time summed up in less than 8 minutes, a real achievement and an achievement. Can't wait the first test with the dremel. Thanks for sharing all!

[joetke]

Glad that you fix the wobble. This project is really among the awesome ones about building a CNC from scratch. Bet that a lot of people will build your device.

Congratulations for your work! I was just surfing the net and discovered your youtube channel on thingverse, and I have to admit that I'm really impressed with what you have achived (the CNC milling machine, your channel and the rest of your videos, which I'm anxious to watch). Carry on with your projects and thank you for sharing them with us! Greetings from Argentina!

[joerecio]

Thank you for all your videos, very well done! My grandson and I are learning as well as enjoying our times together.

If some plastic parts crack when you drill them I have solution. Instead of chucking a bit in a drill hold bit with vice-grips and heat tip with torch till glowing and push through . I ran an Elumatic cnc at work a few years ago and always wanted one since . I appreciate your video.

Thanks very much for sharing this Nikodem. I plan to suggest this as a project to mechanical and electrical engineering students at the college where I work.

[chbonnici]

First class project. Good of you to share. Well done. Keep it up. You are inspiration to others. Many thanks

"if there is no smoke it should be fine" haha thats a good rule

[doctorohmed]

I appreciate your dedication of the CNC router

[forgotrafe]

Great work. Look forward to seeing Dremmel in action.

This is amazing the way the video made was very informative and properly edited since view angle of camera is one of the best diy tutorial i've seen. Keep it up buddy and let me know your next project...looking forward for DIY laser cutter of engraver with 3d printer all in one if possible. More power!!!

I have a problem, one of my cnc shields is smoking. I took a 12v 10a power supply and 1.9 amp motors.

[amigodesigns]

Great job, I would love to see a bigger one for a future project!

[haydenc]

Awesome! Getting closer to cutting some stuff...very cool!
Never heard of cnc.js, man that looks really nice...and it runs on RPi..nice!

[Odonnol]

Excellent video shooting and editing skills! Respect.

I ordered the 10A Power Supply because my dremel is powered on it own AC cord and I did not think I needed 20A to run the three Axis, Did i mess up or will 10 A run the three motors. I am powering one Z, One X and One Y (not 2 Y). Appreciate your input. I posted My adaptor for this Dremel Drill Press conversion to CNC, I know its light weight but my work is small light metal model trains, Thank You, Dennis

Update Nov 27 2023 I have completed the conversion of my Dremel Drill Press with Micro Mark Mini X Y Table into a version of your DIY CNC Mini Milling Machine. So far I used the Dremel Carriage with a unique Adaptor to the Dremel Drill Press Stand. All your recommended Digital stuff. I have only the Z axis operational and yesterday I machined a test part to verify the manual job of Z would work with manual operation of the X Y Tables. It was evident I need to continue to convert the mini XY table to CNC ASAP. I have ordered the Couplers and the CNC Shield of course has the Sockets and I also have the required A4988 drivers. I want to share the CNC Shield is a marvelous tool for us. Spindle control is a little messy but boy does this Shield Save a Bunch of time. I was so happy to see the Stepper motor take on in my first test. Now we are thinking about a load unload robot and some other tools we can use on our train layout. Thank You So much young man.

I'm using a4988 red one for nema 17 1.7A how can i adjust theme ? I do not have any knowledge of electronics.

hello my friend, nice video that you made, i made my self a arduino cnc router, and your instruction helped me a lot, thanks and a big hug from BRAZIL

FYI the esteps need fixing. I ran my cnc for 100mm but measured the distance at double. so $100=400 might not be the setting for everyone.
Update: my $100=24.5, $101=24.5, $102=25, This is an approximation. And I made it run very slowly ($110, $111, $112 = 1) because my cnc would actually stall out when going very fast. Forget about putting on limit switch normal closed because it need a filtering capacitor. Also if using a power plug socket with fuse use a 1.5a. Granted I might not have bought the same spindle as other youtubers reviewers stated max wattage is 50watt and another 80 watt.

Dear Nik really well done. Great job. Just subscribed to your profile. Though I can’t understand how and where to install the end stops. I’ve seen the 3 of your video clips but cannot locate or find where you mentioned the end stops. Anyway very well done. Most probably will start printing the parts until I wait for the other parts.
