Cheap 4th axis tear down and re-grinding
Просмотров 30 тыс.4 года назад
I bought a cheap 4th axis from China, and combined it with a 1kW AC servo motor (also from China). The result is a super fast 4th axis, that can do precise positioning for 4-axis milling and indexing, and also reach 1000 RPM for turning operations. But how good is a $150 spindle mount? In this video I measure the run-out, and improve it by regrinding the mounting cone on the CNC mill. Visit my ...
Riding my self-made recumbent trike
Просмотров 8444 года назад
Full-suspension recumbent trike, built from scratch. It has double wishbone front suspension with 15cm travel (using extension springs to save space), and a rear swing arm from an old mountain bike. The frame is welded from mild steel, with a few parts over-wrapped with carbon fibre for extra stiffness. The front suspension is dialed in to have a lot of dynamic camber, to exactly balance the ro...
Wirebender - better, faster version
Просмотров 57 тыс.4 года назад
Sligthly improved version of my DIY wire bending machine. Parts are printed on an Anycubic Photon S printer. For control, GRBL on an Arduino Mega with a RAMPS board is used. GCode was written by hand, and optimized through trial and error. Music borrowed from Pomplamoose - I hope they don't mind: ruclips.net/video/fUpdfpOPf4Y/видео.html files are available on my blog: www.codemakeshare.com/?p=1...

Lathe threading with GRBL (testing)
Просмотров 11 тыс.6 лет назад
I started adding a spindle synchronisation mode to GRBL, to enable threading on the lathe. First I added the G95 mode (feedrate per revolution), which measures the actual spindle speed with an encoder (on this lathe, a 4 tick/rev magnetic encoder), and adjusts the feedrate continuously in real-time. This works pretty well, but does not synchronise to the absolute spindle position, so repeat pas...

Hi sir I need this product
This is fantastic
Do you know anyone that does this conversation for a price?
Hallo Bauen sie diese biegemaschine auf kundenwunsch ?
Brilliant!
Esse tensionados que traciona o arame é de impressora 3d?
I'm looking for more information about this type of cnc
Nice work 😀If you could what are your thoughts a few years later on the 12Nm Z motor being enough power? I am planning a conversion and considering some sort of weight or gas lift to help or even a NEMA 42.
@codemakeshare this is the best diy wire bender I've seen on YT, have you thought about making this into a 2nd print head to incorporate into a 3d printer? ... think you see where I'm going with this
Hello, I would like more information about this project, could you provide it?
Do you have a set delay at the end of the loop before the code runs again to give you time to snip the part or are you resetting the code manually every time?
What happened with this? Last video for nearly 3 years.
Hello do you have any idea what the bearing block is and are they available as a separate part? Seems they are using the same block on may arrangements though could not find details for the block itself..
no, unfortunately I don't... it's always very tricky to get any sort of documentation about AliExpress products.
can you share the aliexpress url? that you bought it.
Good job!! Great machine!
Do you have problem with z-aksis backslahs?? I have, becouse spindebox first bendt and then it's move
very nice suspension and a great run around Canberra thanks for the Video
looks great, can you share the 3d files? in your website only previous version
Outstanding
Can it do a 90 degrees right angle?
may I know where did you buy the timing belt and the pulleys ??
it all came as a complete set from AliExpress (search for CNC 4th axis or similar - this is the NEMA34 version)
@@codemakeshare ohhh thank you so much ! Good job
Hi! How can I reach you about an idea. Thanks!
Would you be able to share the link to the 4th axis in this video?
Hey man, I know this is an old video, but I hope you see this comment. 1. This is really good work and a lot of people don't appreciate the differences between CNC mills and lathes. Probably about half the G codes are different. 2. On a lower comment asking about what happens at the end of the thread; the default mode is that the x axis just retracts at rapid rate, usually leaving a clean end of the thread. You can usually set parameters that will let you control how long this retract takes, e.g. you can have the thread lead out over 5 turns (good for not leaving a high-stress zone at the end of the thread.) 3. On some of the examples it looks like your thread pitch is a little inconsistent (I don't know if that's just the marker being flexible or not). I can't speak for other controllers, but I know that on older FANUC controllers when you do normal G1 feed cutting the machine will adjust the motion to compensate for changes in spindle speed to maintain a constant feed per revolution. In thread cutting it takes a different approach: First it moves to the start point of the threading, then it waits for the next zero count of the spindle encoder, then the Z axis moves at a calculated feedrate in feed/min and any errors are not compensated for as the thread is cut. For this reason most controllers disable spindle and feedrate override controls on the panel. As long as your spindle speed stays constant, your feed/min on your Z axis stays constant, and you start your Z axis movement at the same encoder count, you should get nice consistent threading.
Very cool! I’m positive your clever enough to automate the cutting as well.
Hi! Where can I get the encoder?
The piece you need to take off is just screwed down
Great job you have reduced it to the barest of bones and the steppers are running smooth as butter I understand your trial and error comments in your other post. But you have me thinking
Very nice👍
Hi, How did you manage to install a larger motor? Or did yours come with a long motor plate? I am trying to remove mine, but got stuck because I can't remove the motor plate... ruclips.net/video/v9tR_K8eTek/видео.html
hellow , how to make this type GCODE please replay , i made but not worked , whn i made to my machine is working cnc plotter type please replay ...'
Thank you for this awesome tool. Wish you the best with your projects as I wait to see how you take this project to the next level.
Great video. Hope to buy one soon. And part 2?
Hallo, steuerst Du den Motor per Hand oder ist dieser auch in die CNC Steuerung eingebunden? (z.B. Start/Stop über CNC) MfG
Ueber die CNC-Steuerung. Ich habe einen VFD, da ich keinen Drehstrom hatte. Spaeter habe ich dann auch eine 24k Spindel integriert (tauschbar), die 400Hz braucht. Mit VFD war es dann sehr einfach, ein Start/Stop Signal anzuschliessen. Geschwindigkeit ist aber manuell, nicht per GCode.
@@codemakeshare d.H. mit dem Frequenzumrichter schaltest du den originalen Motor nur ein und aus und die Drehzahl ist vorab mit den Einstellknöpfen vorgewählt? Ich verfolge deinen Umbau schon länger auf deinem Blog. Habe die selbe Maschine und bin schon lange am grübeln ob ich sie auch umbauen soll und ev. noch eine 4te und 5te Achse dazu... Kannst Du nach wie vor die Handräder benutzen oder blockieren die Motoren das manuelle kurbeln?
@@Patrick-tu8ft ja, nur ein und aus. Drehzahl ueber das Getriebe (mit der Originalspindel), da man so auch viel mehr Drehmoment bei niedrigen Drehzahlen bekommt. Die HF-Spindel hab ich meistens fest auf 24k RPM, aber der VFD hat auch einen kleinen Drehknopf vorne, wo man die Drehzahl verstellen kann wenn noetig. Hab leider momentan keine Zeit, neue Videos zu machen... hoffentlich irgendwann!
@@codemakeshare dachte mir schon, dass eine Drehzahlsteuerung über Software leider nicht möglich sein wird. Ich überlege ob ich einfach ein Relais jeweils auf den Ein und Ausschalter anschließe. Denkst Du das könnte funktionieren?
@@hobbyvideo4030 Koennte gehen. Soweit ich mich erinnere, ist der Motor sowieso ueber interne Relais geschaltet, evtl. kann man die dann auch per Software schalten. Mit meinem VFD koennte ich schon die Drehzahl verstellen, z.b. ueber Analog-Eingang, oder per RS485. Fuer mich persoenlich sah ich aber nicht genug Nutzen, um da Zeit reinzustecken. Ich fraese fast nur Alu und Plastik mit voller Drehzahl. Ein/Aus ueber Software ist aber schon sehr nuetzlich, und z.B. auch Druckluft und Kuehlschmier (MQL) per Relais.
Top Video 👍🏻 Super erklärt 👍🏻 Ich freue mich auf Teil 2
Tilting mechanism is awesome and optimized servo spacing
Very good job. Now automate the cutter.
wiggle wiggle... love the differential servos on the roll and pitch. nice idea :)
Plis code Arduino
I used the GRBL code from github without modifications. You can either use an Arduino UNO with a CNC stepper shield, or an Arduino MEGA with a RAMPS board. I used a RAMPS for this project, with grbl-mega as software. You have to configure it for RAMPS in the config.h file.
@@codemakeshare hello, very interesting device. How do you load the file to run different geometric shapes? Do you use any software to generate the Gcode?
Looks great, when will part 2 be available?
Thank,you for great video,and sharing all the documentation! I'm as well about to buy the Optimum MB4, but i want to using it both- CNC and manual to. Have you planing part 2 soon?Bob
Hei,how about part 2? Whats happening in your life?
So little views???? WHY!!!!!!!!
I don't know! But now it's one more - thanks for watching :)
@@codemakeshare Man, you have soooo much good ideas and genius solutions, wish you could make more videos. Sad, if you ment no more videos...
@@Reburned32 I still have a lot more material, unfortunately the day job is taking up way too much time at the moment... hopefully things relax again next year :)
@@codemakeshare Thank you ,ill be waiting for new videos :D
I am working on GRBL32 on the ESP. How possible would it be to take this code over to the ESP?
I like your loop idea instead of two independent pins. The loop over the top gives the plastic enough strength to bend the wire. I used your idea in my own bender. But I used a wire loop. The wire loop can bend wire of the same material and diameter. And it can do tight bends. The ability to bend both ways is great. And it does not take up space and obstruct previous bends. See a demo of my version here ruclips.net/video/6MN7tmMBlqI/видео.html
Very nice! It's a good idea to use a wire loop. The resin-printed bend gate lasted for a while with soft copper wire, but eventually broke. When looking for other wire benders, I saw a lot of commercial machines with a retractable single pin, which is a lot more complicated. I think this version works fine for a lot of use cases, and is a lot simpler. It's great to see your machine bending in 3D, and that the 2-way bend with the loop works there as well!
Hey man, can I see your gcode? I've built something similar and am trying to get a handle on nice corners
I don't have it available right now, but there's nothing special in it. With the soft copper wire, the trick for smooth bends was to rotate the aperture, and then just feed wire. The bend radius was trial and error, my gcode was just hand coded and tested until it looked right.
Hello; good work, congrats ! MB 4 is probably the most solid desktop mill before stepping up to a knee mill. If you run the dial indicator on the table, what is the flatness accuracy ? Obviously small local deviations due to surface roughness should be discarded.
Hi, after my tests i measured a deviation of ~0.01-0.02mm along all the X axis.
Very interesting analysis and repairs!
Could you tell me the time needed to build this and budget spend on material?
Seeing the servo move back in forth leads me to believe the belt drive may be causing some of the tolerance issue.
that's a separate issue - the belt pulleys aren't perfectly centered either. The bearings are tight though, and I don't think that any wobble from the pulleys transfers to the axle. After re-grinding, it was almost perfect.
