Hello guys, I hope you all doing well. So I’ve been collecting the parts of the MPCNC but I had some problems choosing what type of things do I have to take. First,
The Power supply.
Here in the parts page the power supply link looks like a Laptop charger and I don’t know if that’s strong enough to run a cnc machine, because none of the YouTube videos used it.
Lastly and most importantly the board. So I was planing to buy the kit but it is sold out sadly, so I saw an assembling video and the person used Arduino mega i think or something like that. The point is the put for the kit was also sold out.
This is it
The laptop style power supply is fine. It takes quite a lot of current to run a laptop, and surprisingly little to move these motors.
I’m not sure what you are asking for about the stepper motor cables. The important thing is the ends, and if you are wiring them in series or dual endstops (dual motor).
That is the RAMPS combo. They work fine. They are fragile though. The rambos Ryan sells are tougher to break, and they come flashed with his tested firmware. If there was one thing I would suggest buying from the store, it is the rambo. There are instructions for the ramps in the docs though, and there is information on flashing the arduino. It isn’t rocket surgery.
I would like to thank first for helping everyone here.
I was planing to by the Rambo but the shipping cost is very expensive. The CNC will cost around 700$
I’m willing to make it like this guy https://www.youtube.com/watch?v=IpJ__YZnttw
Regarding the endstop/ dual motor. I believe he is not using an endstop. Right?
What do you mean by fragile? … Will I have to replace it sometime? … If yes, due to what?
My working space area is 1x1m do you think the wires comes with the Nema17 are enough?
If you go with the laptop power supply, throw that little adapter in the corner in the trash, cut the end off the DC supply cable, and use the bare wires directly.
The ramps board itself is fairly bullet proof, it’s the cloned arduino under it that’s the weak point. It’s fairly easy to cook the little 5v voltage regulator on it. It’s an easy fix if you can solder, but annoying. They’re also cheap, cheap parts, usually no qa, so sometimes you get them dead on arrival. I have a couple spairs now, just in case.
