Hobby CNC Mill

[Hecate2006]

Hai MCSCoder, may i ask about the circuit sheme.

[CHARLIEDONTSURF1982]

nice work ! "psicotron"

музыка бесит

[MCSCoder]

@shadowgmable : I am sorry the music infuriates you..... Unfortunately this is one of my favorites so, if you don't like it, mute your speakers....lol

[shadowgmable]

@MCSCoder Не обижайтесь :) О вкусах не спорят, я просто пошутил)) Видео кстати понравилось)

[vigaroux]

nice work sir.

[MCSCoder]

@vigaroux  Thank You....

[CncObsession]

Nice build and documentation. Did you heat form that Nut after machining the block and if so, how much backlash do you measure? How about longevity of the nut in use? I hear they last a very long time, is this true in your experiences? Again regarding the Nut, it appears in your design that you could possibly "squeeze the 2 halves of the nut together more to adjust the tension and or backlash, is that true? I have been thinking of something like it. Excellent job.

[MCSCoder]

@CncObsession :, Thank You.... The "Nut" assembly is machined out of Delrin, it is a type of polymer plastic that resists wear very good and it is also very easy to machine, I have not been able to measure any backlash whatsoever have used machinist dials and all to check and so far so good.... the "Nut" itself moves up and down in its casing, and the casing actually can move left to right, to compensate for bent axles and all.... and yes, you can tighten the nut casing to adjust nut tension...

Hobby? This looks kind of professional. At least it shows you have quite some experience in electronics and metal work.

[MCSCoder]

@agilux : Thank you.... but yes, this is just a hobby CNC, but I do work in the metal fabrication field and also design electronic components and embedded circuits...

[2baylord]

HolyShit!!!!!! u could go 2 MIT with those kind of skillz. Very impressed.

[MCSCoder]

@2baylord Thanks, I appreciate it..... thanks for stopping by and checking out my vids...

[boxa888]

where u get the metal, that cost alot these days lol. woods the best i think i can put together. great work, where did you learn the electronics from, the most i have ever gotten is a 555 timing chip to run and some basic circuits off of that, are the chips adder chips? anyways, great work!

[mundenez]

Yes. I'm well impressed. Had to turn the sound off though as its too heavy for me. Would have been great to hear you talk through the process.

[Compwhiz128]

GAAAAWDD, I lust for such toys, and yet you're talking about $10,000 worth of equipment...

Awesome job though.

[BosenMike99]

I think this might be the highest quality home built on you tube. I'm impressed.

[MCSCoder]

@BosenMike99

Thanks, I appreciate the comments!!

[william4art]

Nice vid.. nice detail work on the machine and a cool megadeth tune too

[pogi09282805724]

least i can do to say ur great is to subscribe!!

[mike36801]

Very nice CNC !

Where did you buy the milling bits from ?

[MCSCoder]

@mike36801 I had bought these bits locally at a store called Harbor Freight.

[mike36801]

@MCSCoder Thanks for your quick response, I have one more question if that's OK with you.

What stepper drivers do you use ? (I use L297 + L298, but it does not give enough amps for my Nema23 motors)

[MCSCoder]

@mike36801 I have been using the UDN2998W for my NEMA23 Bipolar Steppers.

[mike36801]

Very nice CNC !

[DrFrankensteam]

Excellent!!!

[NOCNOTCAUGHT]

Totally Awesome - Great Job!

Now to your web site.

Great tune too - Thanks!

[diegosua2005]

muy buena tu maquina. me podrias compartir tu soft. yo hice uan parecida. desde ya muchas gracias.

[Ibringthetruth1]

didn't understand how the pcb's were etched.

just dremeled?

The motor came from where? treadmill?

[MCSCoder]

I layed out the pattern for the circuits on bare copper boards and carved the traces by hand with a dremmel tool. Not sure what motor you are talking about, but the 3 stepper motors did not come from a treadmill... they were salvaged from another machine that used steppers for material processing.

[Ibringthetruth1]

the drilling motor that has the bit?

[MCSCoder]

that is not a motor, it is a spindle that gets attached to a motor to do the drilling and milling, it is something I had made for the machine but never found a suitable motor to drive it yet, I am looking for something with more than 30,000 RPM's.

[Ibringthetruth1]

i might have mixed up your vid with someone elses.

Why 30,000? That is pulsem motor speeds.

I suggest calling a fitness store that repairs treadmills. Very nice pulsemodulated motors.

[MCSCoder]

30,000 RPM's is the max for most variable speed dremmel type tools, I wanted something that can go up to 45,000 RPM's.

[MCSCoder]

Thank you for the compliments, I appreciate you folks taking the time to check out my stuff...

[libed91]

amazing!!!

nearly everything used in this cnc is homemade.

really, nice work!

[MCSCoder]

Thanks, for the comments, not only is almost everything homemade, but almost everything is recycled material.....

[r32adt3db]

fantastic work!

[MCSCoder]

Thanks! There is a more detailed work log on my site, if you care to see more on this project

[GaryGarrett]

great video... very inspiring! five stars!

[MCSCoder]

Thank you!!

[PLSteamer]

oh yeah megadeth and machines what more is there to love!!!!

[tclonedelta7]

how much would you say this project would cost minus the electronics to make?

[MCSCoder]

Qyite a bit sorry to say, the bearings alone will cost nearly $600.00!! That is why I salvaged all the parts, and purchased most of my bearings at a local scrap yard which cost me about as much as a couple of pounds of scrap metal.

[guerd87]

very nice, i love it! Im half way through building a hobby mill for building rc parts. whats the name of the music?

[MCSCoder]

Psychotron By Megadeth..... Thanks for the comments.....This is 3rd attempt at a hobby cnc, first 2, are in a scrap pile, lol.

[guerd87]

thanks. My one im building uses a cheap benchtop manual mill and im adding auto axis control via stepper motors. Should be able to handle alloy which is what i want to use it for

[MCSCoder]

My CNC can handle aluminum alloys and other soft metals such as copper (havent tried any steel, since I dont have any water cooling on it), it all depends on the spindle torque/speed and the feed rates... I was thinking about purchasing a small benchtop model from Harbor Freight and converting it to CNC.... But I have to finish my 4'x4' CNC Router table first.... so many projects, so little time...

[mrmartyman7]

great job

[mylyrics]

Great video and soundtrack! I'm glad to see that someone else thinks of this song and CNC in the same breath.

[MCSCoder]

Yes I would trust this machine to mill aluminum billet. I would recomend using a more powerfull (higher torque) spindle motor.

If you use a high speed cutter, with a high speed motor with high torque capabilities, you should be able to mill at higher speeds.

You would just have to calculate the mill bits ability to remove chips and what feed speeds and spindle speeds need to be set at.

[vivaelrealismo]

Awesome video, music and all. The text was informative.

Would you trust this design to mill aluminum billet, at low travel speed? I'm not sure what the correct term is... feed speed? Movement along axes/into the material?

[MCSCoder]

Instead of trying to steal my design, by stealing my video, you should email me instead and maybe ask for the schematics instead of being a thief....
