arduino mega 2560 pinout
No, oh, no as well testing it, and these are NEMA 23 stepper motors. These are 450 pounds inch motors. I have another one here that I’m going to be using for our fourth axis, eventually once gerbil or garble or garble, whatever anyway gerbil supports the fourth axis actually downloaded the latest version of the durable for the mega, which is a branch specifically for the yet Arduino Mega 2560 and I’m just going to show you a quick zap. I want to do this on the cheap, but not skimp on the quality of the parts. So you know here those so I’ve got three. My 23 overts for the x yampz axis and I actually use some network wires from category 6 cable and basically bundle the pairs together, and I soldered these ones and crump these ones anyway. I’M. Not sure how I’m going to connect these. But I want to have the motors detachable so anyway, I bought these motors off of some guy on eBay and put the links for all the parts and software in the description below. So I got a really good price on these or 100 bucks, even for the 3 shipped free, which is a pretty outrageous, and I opted for the dual shaft motors because I’m going to make some knobs here that I’m going to be using to fine. Do some fine adjustment, you can’t do that with these warmers, you have to actually step them through the software.
This way, I can actually you know any moving on with the next step, so I like to do this with the Arduino and I didn’t want to pay a whole bunch of money for some software to to do. You know the G code and to actually you know, send people to interpret the G code and there’s the guys who do the development also have, I think, I’m, not sure if they’re associated or what have you but the guy who does the universal g code? Sender? Actually has a GUI version, which I’ll show you in a bit which really works amazingly well. So anyhow, I got for these TB 6600 micro step drivers for around the steppers, and you can see I actually set these up. I’Ll show you the dip switch setup, because I found a lot of videos on YouTube lacking. So this one here has, as you can see, switch 2 amp 5 on forgive the quality of the video. My phone is actually shot and 2 amp 5 basically mean. If you look here, we are actually going with a 8 micro step, and these are three and lower. So I’ve switched number 5 actually sets it for 3 amp steady with a 3.2 mm peak, which is perfect for these motors, and I have them connected now, show you how they’re connected, because this is a big problem, though this is one thing I found really lacking The direction negative pulse, negative I’ve, actually wise them together, and you can see here this ground wire – goes to a common ground terminal here, where I’ve actually also in time wiring.
So to make this simple, and then we have the direction positive pulse positive, going to the Arduino – and this is the z axis. I’Ll show you the x axis here goes to port 24 and 30 on this gerbil version. It’S, a 1.1 II released the December 19th of this year at the last year. Actually this is 2016 to be this 24 volt, 15 amp air power supply. You can see I’ve wired, the load, neutral and earth, and that goes to a plug, and then we have. These are the three on this side or ground. Three on this side are positive, twelve volts. So I have to show you here negative and positive going to this terminal here, where I split them off, so I’ve got three positives and they all go to the positive VCC high voltage, positive, positive, positive of each one and then the negative, which is the ground. I’Ve split off over here, which basically becomes a common ground for pretty much everything, so all the direction, negatives pulse, negative and ground, even the high voltage ground all are commonly grounded here. These are all commonly grounded. The Arduino is grounded on the ground. Pen. 5. Volts comes to this rail applying the 5 volts bursts of a second that’s to power. These relays and I’ll explain what those are, and I just added an extra ground wire here coming from the this grounding terminal, just to make sure I’ve got the positive ground happening over here.
So then we have a solid state relay here. Then I got on robot chopped comm or you can get these on eBay. This is a non moving parts it’s, just a solid state relay that’s going to control the skin, and this is a dual relay. I got from also also from robot shop common it’s, a DF robot anyhow, and this will be for mist and flood and for the spindle and those are connected. The positive, the VCC and ground are connected to 5 volts and ground 5 volts powered by the Arduino 5 volts here, and this rail is, as you can see, jumped all the way across to bring all the red rails on the exterior perimeter to 5 volts. So we have the 5 volts going from 10 6, which is the digital pin. 6. You can find all the pin pin outs for the zero in the Arduino libraries gerbil CPU map h5. If you look at that, you’ll you’ll see all pen assignments, but you can see the XYZ axis or pin 24 25 26 ABC are going to eventually be 27 28 29. Then we have Direction. X is 30 y, is 31, Z is 32 and I guess you know rest will follow and we have the spindle enable on pin 6 spindle direction on pin 5. I don’t have those spindle directions set up right now. I don’t think I may have a one of those pencils are I’ll, see you eventually, but anyhow, then we have an eight and nine hour for mist and flood or flood at mist 2 respectively, and those will be powered up here.
I’Ll show you how this all works, it’s actually really simple. I made absolutely no modifications in the software. I just downloaded it flash to the Arduino and using the UGS platform software and then, like I say, I’ll give you all the descriptions in point below makes a very simple setup and it’s outrageous. So let me just show you how this works about this all wired up to my little Windows, 10 laptop. So just connect the Arduino, you can say I’ll plug in the power supply to supply more power to the stepper drivers. As you can see, the real powered up indicator lights and just show you how simple this is using UGS platform software sure. So this is all open source and these guys are putting together some really cool software. So anyone want to put together your three axes to become eventually Forex of CMC herbal mega it’s, a branch of original that’s. The way you go so this is connective, as you can see, I’ve laid out my screen this way so I’m just going to go ahead and load a sample file leg out from the UGS platform download. Neither this one or closure it’s pretty cool. Thank you see that there and the virtual setup of the machine now the only problem I found to actually make this all work, because you have to put the spindle to 99 that 100. For some reason it just never goes on so I’ll set the speed to 25000 rpm and now it’s number 99 percent movie.
I guess that 25000 rpm, magic and we’ll go ahead and fire the self you check this out. No modifications whatsoever, you can see. Spindle is gone, see the real a move on wanted off with the flooded mist, so that’s, the other channel there yeah. This thing is ridiculously simple modification, especially when these guys were actively developing a software or so imagine the ready acts at nagging the for faxes. For so I can’t wait to do that because I’m, probably gon na, be just no ready and build this CNC once they oh. By the way we show you this. You can also override g great, bring it down to a halt and concealer, as opposed I’ll. Just reset it will see just pick up anyway, stop that this is a hard stop and return to zero here to fly now for the the setup, you know read the wiki, you know for eight steps. You know I’d like to use a 101 110 of an inch per revolution, lead screw, which will give me a 10 revolutions to do one inch and what it basically works out to is for 8 micro steps, there’s the formulas and everything out there, but for 8 Micro steps: it works out to six 29.9 21 for x yampz because I’m, using the same motors by up this value to 2000, because these motors actually support no problem. The acceleration I doubled as well, and I set some soft limits, but that’s pretty much it I mean this thing is just ridiculously cold.
You know jogging convincing season, Macy’s, sorry minutes New Year’s Day happy. We are all hope you enjoyed us. Have any questions. Please feel free to leave them in the comments and reason I chose to do this by the way, just as a closing note, as I want to do this, the cheapest way possible. You know if you can sever. You know 100 for this. I paid like 48 dollars for the four of these so clean for 12 bucks each. I paid 25 bucks for this time. Ten forty bucks 500 bucks. Actually for that, so it comes out really cheap, and this software is just really amazing. Just to show you, quick, serious stress tests show you what this does, because the acceleration doubled the accelerations and doubled the maximum speed.
