Thank you for taking the time to answer questions viewers had in the previous videos and responding to comments. Your explanations helped me understand the whys behind our decisions and help me decide on my own projects. The talking is helpful. I see the same questions asked again and again across different videos of the same topic. It may save you time and provide answers if you create a template description with an FAQ section and use that across all the videos of the same series. Then add additional info at the top that's specific to each video. For example, have a section for Parts URL, price, then a section on CAD availability, etc. Keep up with the fantastic videos. Thank you for sharing your knowledge to help others.
Nice video, thanks for your sharing, you are amazing to upgrade the CNC by your ownself. good job. i know how difficult it is. we also have our own CNC machine.
I decided to go with Nema24 closed-loop steppers. I figured it would be a lot better and let me know when the steppers can't keep up, especially with the alarm lines coming out from the stepper drivers. Also, it depends on the stepper driver but it may actually try to compensate for the step loss before it sends out the alarm (so if it isn't recoverable then it will send out the alarm). I went ahead and bought a raspberry pi 4 to use as my cnc controller via LinuxCNC. I also bought a couple of Mesa FPGA cards to go with the Pi for high-performance stepper pulses and GPIO so the Pi doesn't need to deal with all of that and just focus on giving the FPGA instructions to control the machine. I could eventually wire the encoders from the stepper motors to another Mesa card, allowing it and Linux CNC to handle compensation and alarm work as well, but right now I don't think I need that, so I'll just let the fancy stepper drivers handle that. Thank you for your awesome videos! You and Marco Reps are big/main reasons why I am building my own machine.
Perfect job , you have done it with care , so this mil needs realy a very acurate 4th axess to be complitly ready to mil all witch cnc machins does , Good lick
real cool cnc mill. i search for a workshop today. if i find one i build also a cnc like yours. this times i make with a little Laser Cutter und a Diy 3d printer some projects. but my channel very litte at the beginning. i hope i can make some cool vid. like yours :)
How did you connect the closed loop stepper motor and stepper motor driver to the controller. I have watched several videos but none of them show how to hook up the closed loop stepper motor and driver to any control board. Plz make a video on this. I would appreciate your help. Looking for another video of your about cnc. Plus if you wanna make video about upgrading a lathe to a cnc or building one from scratch. That would be huge plus. None other video has the quality stuff you have uploaded
excellent job, in the future I want to build one like yours, but now I would like to ask you how you to put the micro steps setting to configure the drivers to obtain the velocity you are work on? thanks for share all your work.
For steps Mach4 has built in calculator, for velocity start low than keep going higher until you miss step, once you have that value take away 20% of it
VFD spindle is not suitable for this type milling machine or cutting steel (you seemed mentioned this), will you plan to switch to direct or belt drive servo spindle that has more torque? BTW you machine construction is very good! Were all steel structure bolted or welded together?
Hi. So which closed loop controller are you using? The one at the bottom left of your panel. Did you have to change a setting(s) related to the lead screws? I am also in the same position, but my driving issue is accuracy, as opposed to speed. I also end up with scrap parts.
Very nice machine and good job with the presentation! After using your machine, are there any areas you would build heavier (more rigid) if you were to build it again? Thank you.
I Like all your videos. You are very precise. Une suggestion though: you could put the link to the products as aditional info ans so woul be quite more interesting. Thank you.
Very nice build. I'm happy to hear that you filled the column with concrete as I didnt see this in the build video. It is a cheap way to get more rigidity and less vibration. What is the spindle that you are using?
This is super cool. I'd love some more info on your spindle. Where did you source it? What specifically were you looking for? How much did it cost you?
Im looking to buy a mill and convert it to CNC, you definitely confirmed my thoughts about getting closed loop stepper motors for this job. The only thing that makes me wonder: why would you want to stop your operation when you lose steps? Dont you want the closed loop stepper motors to adjust in real time, and continue milling? Greetings, Jeff
Hi Jeff. Thx for your comment. I should of be more clear on stoping the operation. Sometime even closed loop can’t recover the steps due to too much load or speed, so at this point you want the board to stop the machine to avoid scraped part or broken tool or crash.
they do correct the position, but in case that is not possible let's say because they get stock in one place then the alarm function stops the operation before major damages occur. It's an handy feature that both closed loop or servo have.
vince, i wanna asking, with this current closed loop stepper motor with encoder, are you still lost your machine coordinate when you shutt down your laptop or machine?
Thank you very much for your video sharing. Can you Tell me Some information. I want to know the lenght of Ball screws: Y,X,Z and Size of Bellow Couplings . Thank you .
When upgrading to Hybrid Servos, is it literally just a direct swap, or is there some programming or software to install? Do you have to change settings in your CAM software? Or is it just a matter of knowing you've got more speed to work with when calculating speeds and feeds recipes?
Are you still satisfied with the results of the closed loop steppers. I’m debating on using some similar to yours or maybe Teknic clearpath servos/steppers.
Good video sir , now according to your experience do you recommend these closed loop stepper? And is there any issues in the machining I mean no losing step like open loop?
Почему сразу серво двигатели не поставили?? шаговый мотор с энкодером все равно остается шаговым мотором, и один из главных его минусов это резонанс потом падение крутящего момента!
Thank you for not sharing CAD data! Don't let people get dumb.
BTW cool project, could be improved but after the first time everybody knows better.
I’m excited to see the parts that come off this machine.

I find my CNC runs so much smoother and faster using the servos, no missed steps and higher quality parts.
Very true.

I used calculator built in to Mach4 to fine tune the all the axis
Maybe add some linear encoders as back coupling, that way mis steps don't matter anymore.
Plz share the link for the spindle purchase and specifications
Thank you for your video!
Very nice machine and good job with the presentation! After using your machine, are there any areas you would build heavier (more rigid) if you were to build it again? Thank you.
I would make Z column heavier

Done. Check description
Thank you for the info it will be usefull
Can you show the wiring and what board did you use?
Very nice build. I'm happy to hear that you filled the column with concrete as I didnt see this in the build video. It is a cheap way to get more rigidity and less vibration.
What is the spindle that you are using?
Thank you.

Not it doesn’t loss
@@advanceair ok thankyou vin, god bless you 🙏
@@advanceair ok nice build, are you using stepper/servo brake for z axis or just you swap with closed system without brake on your z axis?
Thank you very much for your video sharing.
Can you Tell me Some information.
I want to know the lenght of Ball screws:
Y,X,Z and Size of Bellow Couplings .
Thank you .
Z and Y are 30” X is 37”. Couplings are for nema 34 shaft which is 14mm
@@advanceair thank you
When upgrading to Hybrid Servos, is it literally just a direct swap, or is there some programming or software to install? Do you have to change settings in your CAM software?
Or is it just a matter of knowing you've got more speed to work with when calculating speeds and feeds recipes?
In my case it was just swapping the hardware and very small step adjustments in software.
Are you concerned that if you miss a step, even with closed loop steppers, your part will still be ruined?
It it miss any step machine will stop.
Vince can u tell me please more about your controller? And what Kw spindle?
Controller is PMDX 424. Please see description on full build for all the part list
Hi Vince! Did you make strength and rigidity analysis before building?
Yes I used fusion 360 simulator to test it, that is why I ended up filling Z coulomb with concrete,
Are you still satisfied with the results of the closed loop steppers. I’m debating on using some similar to yours or maybe Teknic clearpath servos/steppers.
I am happy with closed loop system, but if i make cnc today to future proof it ill go with somethings like clear path
Good video sir , now according to your experience do you recommend these closed loop stepper? And is there any issues in the machining I mean no losing step like open loop?
Close loop is great , I make a new CNC I’ll use servos
great videos. What welder do you have?
Thank You.

Nice job, Vince. Did you do any accuracy checking?
Yes. It should be in video.
U payed alot for closed loops maybe a little more and u could do servo motors. Much more faster accurate and nice
True. Maybe next machine
