hi guys so school just got out and i'm going to build a cnc machine i'd like to finish it within 2 weeks. i'm wondering which driver board i should use. I think this goes without saying but it will have an X Y Z axis with the rotor. Will this kit be usable http://www.banggood.com/LCD12864-RA...-Control-Board-A4988-Driver-Kit-p-936768.html or should i buy thishttp://www.sainsmart.com/sainsmart-cnc-tb6560-3-axis-stepper-motor-driver-controller-board-cable.html? kpid=181_en&gclid=Cj0KEQjwhPaqBRDG2uiHzpKLi6ABEiQAk_XXiUdK48WRU5A7cOpkaV0Y97Q-MBO4uwPXh8SBGJa0F6AaAjjk8P8HAQ is this one a better option, and what drives the rotor. If not could someone link me to what i should be using thanks in advance
Not enough info miles. what are you routing? what size machine are you building? Do you have the machine designed yet? On a budget? On that note, I recommend one should choose and purchase electronics last.
I would probably steer clear from all in one, if youve got a board with 4 axis and one blows your a bit stuffed, with individual drivers you only replace the one. DazTheGas
what are you routing - 6061 aluminum what size machine - X- 15'' y-15'' z-20'' do you have the machine designed yet- no but i'm probably going to do something similar to the ox budget- $1k max thanks
Current is the most important factor especially for cutting aluminium. Your first link is for 3d printing and is likely to be of a very low current output so no good. For a reliable cnc setup you need mosfet drivers. They are more money but from experience, Toshiba chip drivers as in your second link, are half the current they claim, run really hot, and loose steps under cutting load, and you will end up throwing them away or banging your head against a wall every time you use them. This is partially due to running a stepper at 1/4 of the rated current you get 1/4 of the possible holding torque, hense why its important to run them at full current. With mosfet, the rated amps is pretty much what you get so just match to stepper motor current. Example of a mosfet driver: http://www.cnc4you.co.uk/Stepper-Motor-Driver-4.5A,-50V-CNC-Microstepping-CW5045 with electronics you get what you pay for really. anything below £25 per a driver you can guarantee its poor quality.
Have you decided what software you would like to use? That also will affect you choice of controllers/drivers.
I agree with John. The tb6560 is junk. Don't get me wrong, I think they do what they're supposed to, but they aren't my first choice for a low budget machine. Do you plan on simple profile cutting or elaborate 3d engraving?
this is what i'm planning on making http://gyazo.com/356c5ee24656175d42b4a38566cc6c09 i'm going to be making 80% lowers for ar15's and as far as software goes i don't know forsure what i'm going to be using so i'm completely open to suggestion
Save yourself the headaches and possibly your life or a hand at least and start looking for a used knee mill.
Sorry to say it but you'd need to be a magician to make that with an ox. That will require a 5 axis mill or water jet and a fair bit of know how. Best taking that one to the pro's. But id be surprised if you can get that made for under a £1000.
i'm not making a industrial cnc machine or anything massive so i don't see how i'd lose m hand or anything haha i'm building something similar to this https://othermachine.co/othermill/features/ and i looked at the knee mill but it's out of my price range haha i'm 15 and have a little bit of money i'd like to build cnc machine with
You can build one..just not with an ox. The ox can't hold those types of tolerances. Check out 6s6m6 on YouTube. He has a great series on machining the lower on a knee mill. It'll give you a better idea what's involved and might open your eyes to some reasons why an ox isn't the best tool for that job. Have you looked into these yet? https://ghostgunner.net/ Good Luck miles. keep us posted.
yeah i did have a look at the ghost gunner one but i think i build myself for less and i'd rather build it myself anyways so i know how everything works but again thanks for the input cheers
there you go miles - making the part you wanted with that. (quite impressed actually) Just dont go blowing yourself up with a diy gun.
no the ghost gunner is crazy awesome i looked at it months ago but there is tons of negative media associated with it, not that i actually care about that but there's really nowhere to purchase it haha it's kinda what got me into wanting make my own but on there site you can only pay to be on a waiting list for it not actually purchase it, which would be fine but that's been the status of it for months
i could but i want to make a bunch of 80% lowers over the summer to sell, and yes it is legal if you leave 20% of the lower to be completed it's considered a piece of aluminum not a fire arm
