See how a PICO Made CNC Awesome by solving a major interface problem

- A Raspberry Pi PICO was a major contributor when I added an automatic tool changing system to my CNC machine. As with most complex electromechanical devices, interfacing between devices is a challenge, whether it be electrical, or mechanical. See how the PICO helped solve one of the roadblocks in this complex system.

ATC and vacuums for clearing debris are the two best quality of life features for any CNC.
Awesome work DeHut
Hi Pique!
I couldn't agree more!!!! Thanks for stopping by.
Cheers!
Chris
Great video and showing perfectly where and how microcontrollers can easily solve problems on other systems!
Thanks Norbertbans, much appreciated!
Cheers!
Chris
Great project, never thought of using microcontroller for this type of purpose.
Excellent explanation.
HI chirots,
Thank you very much for the Kind words. Yeah, micros can be used in a lot of places PLCs are typically used. They are not as "hardened", but they certainly can get the job done.
Cheers!
Chris
@@MakingStuffwithChrisDeHut I usually use PLC for any kind of projects either big or small, because it can be written quickly and many HMI monitors can be connected without crazy codes and classes.
Built a solenoid winding machine with Pico. I spent a few days testing codes whereas I could do that in PLC for just a hour.
Always admire all project creators such as you.

Yes, PLCs are a powerhouse in the industrial world. Outside of "work", I have always favored the SBCs and Micros, probably because of cost. It is hard to find a $4.00 PLC. Most importantly, as long as it is fun and interesting, PLC or Micro are great devices!
Cheers!
Chris
@@MakingStuffwithChrisDeHut Thanks for your responses. Nowadays, channel creators hardly respond to any comments or questions. By the way, you are definitely right about the cost of PLC. I guess I need to polish my coding skill in order to build more complex projects. So many ideas with limited programming skill.
Hi Chris! I really love your thumbnails and video titles! All the other videos I have seen regarding the Pico have very "straight-to-the-point" titles and thumbnails, I don't say this is a bad thing, it's really great when I am searching for something specific but when I just feel bored or like trying something new your channel is my go-to! Keep up the great work!
Hi Kirgo, Thank you so much for the very kind words and I greatly appreciate the feedback - it certainly helps keep me going.
Cheers!

Cool Hack! How do you align the spindle upper wrench accessible groove pair aligned with your pneumatic top wrench?
Hi Tom - THANKS. There are more videos on the channel explaining all the details.
Cheers!
Chris
just cool
Hi matthiasl5253 ,
Thank you very much!
Cheers!

Really nice CNC router. Will it cut metal ? I have a traditional milling machine and I am thinking of buying a new one just for CNC conversion.
Hi AllTheGearNoldea!
Thanks for the kind words. The router was never designed for metal cutting from the beginning. The spindle is not at all suitable for metal cutting (at least anything more than scratching metal of the part) and the lightweight aluminum frame isn't rigid enough to real cutting. Like you, I have a bench top mill with an R8 spindle with a digital readout. It serves me well for all the metal working stuff I do. I was giving thought to doing a CNC conversion on that or a different mill but just haven't had the motivation (need) to do it - yet.
Cheers!

multicolored bargraph, 4 colors , i know of red/yellow/green for sound volume, heartbeat idea, nice
but why not use the spindle motor to turn the collet open/closed, not delicate enough ?
Good morning Ben,
The reason is that the spindle motor is a 24,000 RPM motor. It can only run between 7,000 and 24,000 RPM so it is impossible to start the motor then stop it quick enough. Furthermore, the motor has zero torque at low RPM. The stepper along with the gearbox give me great mechanical advantage for tightening and loosening the collet. This is a major driver as to why this is complex and why no one else has been able to achieve it. Lot's a crazy crap to get this tool change system to work reliably and accurately. It was a LOT OF FUN though!
Cheers!

That thumbnail lacks a few red circles and arrows :P
I just built a similar project with a pico, stepper motor (24v/2.4A), 16x2 LCD display, 4x4 keypad and two buttons to control a set of rollers very precisely (with length input and few other over engineered things) using bits of your tutorials among other things :)
I see that your driver is quite expensive at 60$, i used cheap A4988 but the torque was terrible and it was missing steps, switched to DM542 (~30$) and now it works perfectly, is there any specific reason why you chose that Tic T825 driver?
Good morning Phlex,
First things first - yup, that thumbnail is an experiment. Obviously not my "personality" but I wanted to see what would happen if I stepped out of my norm and do something others are doing. It will be interesting to see if the views goes way up as others say it will.
Glad to hear you are using the tutorials so you can explore more and have more fun.
Yes, the driver I selected is very unique in that I can, via software control, set the output torque. That is absolutely critical for the success of the tightening device. Without that, the tool change system never would have worked.
Cheers!
Chris
