Calibrating your 3d printer is not that difficult today. I’m going to show you how you can calibrate your Android 3 pro or maybe other 3d printers using Marlin 20 Coming up on Zachary 3d prints. Last time I did an upgrade on my ender3 pro with the Big 3 Tech, SKR MINI e3 Mainboard or Controller Board that one has Standard Stepper settings for the end of three pro. So after this upgrade that I did on the controller board of Myanda3 Pro. I want to make sure that every motor Every Stepper motor is precise as possible. Sometimes it’s needed to calibrate your 3d printer sometimes when you are doing upgrades on your 3d printer, for example, different kind of Stepper Motors, different kind of main board or some other components that makes movements. You have to make sure that everything is well enough calibrated. So in my case, I use a new main board and now I want to check out. If all xs are calibrated well enough, and maybe if I can improve just a little bit more that it is more accurate as before. So now we are going to print a new calibration cube and lets. See what is going to happen? The calibration cube is printed and during the slicing process. I made sure that the y x is in this direction. The X X is in this direction, and the Z X is on top and on the bottom of the color, bracing cube. Now we are going to take it off. The 3d printer, And let’s see which kind of measurements we are going to get. There is only one tool that you need to have. When it comes with 3d printing, I also mentioned that useful tools to start with 3d printing and one of them is the caliper. So now we are going to measure the y x. The y x is without too much squeezing 20.1 When you are going to calibrate your 3d printer, the XX, the YX and the ZX. We are going to use one formula, and that is called the size that is supposed to be in this case. It’s a 20 millimeter calibration cube, so in every direction and every X, it should be 20 So that is our first number that we going to write down. My 3d printer is in the YX. Well calibrated. We are going to check the XX as well and it’s 20 so I can leave it as it is or I can change it, but if I’m going to change it. The setting now is 80 When I use 79 points something, then it’s going to be a little bit tinier, a little bit smaller in the X direction, but then it could be more that on in this case, it’s only a calibration cube of 20 millimeters, but if you are going to print bigger parts or parts that should go in each other like a puzzle like the unmoved robo parts. Then you have to make sure that everything on your 3d printer is well enough calibrated, so yeah. If I don’t squeeze too much or just hold it Normally, it’s 20.1 in the X Direction. Let’s measure the ZX so in the height in the height. I have 19.99 so a little note. Then you write the formula down 20 from the 20 millimeter cube times. The current step in this case, it’s 80 and then we are going to divide it by the measured side of this calibration cube well, for the X hex. It was 21 in the Y X. It was also 21 and in the ZX the last measure it was 19.9 Now we are going to use the formula when we are multiplying the 20 by the 80 we get 1600 1600 we divided by the 20.9 and then we get 79.6019 you can do 79.6 because we have in the Y X and in the XX. The same measurement we can also apply this number this figure for that X as well then for the Z high, we had 19.9 We have a different kind of current step for the ZX. It’s the height and the height is 400 When we multiply it by 20 we get 8 then we measured it. We divided the eight thousand by the nineteen point nine, and we get four hundred and two. So as you hear for the horizontal axis, we have a lower figure because the cube was a little bit bigger, but in the height. It was a little bit smaller, but just a little bit, you can say. Well, I’ll leave it as it is like that, but you can also check. If you can just fine, tune it a bit more. So now we are going to adjust the steps. In the 3d printer, press the knob and go to configuration, then we go to advanced settings and then we are going to steps Slash millimeters. We press the knob and then we have the X step millimeter setting 80.0 for the formula that we had we had 79.6 We press the knob and we just go a little bit down and as you can see, it’s not that much, but now we are calibrating our 3d printer in the x steps per millimeter. Now we do the same by the 80 80 We dial a little bit down. It’s not that much. Then we press the knob and for the Z step. We are going to go to 402. This is a little bit more there because it’s just one digit behind the the dot. We leave it as it is now, and we go another step back, and we say store settings. Now we get a beep, which says that everything should be set. We are going now to print a calibration cube again and let’s see how the measurements are now. So like you can see. I already put some leftover filament in case the other one runs out. The print is ready and let’s see how the calibration did work out, So we take the caliper again. We measure the YX, And what do you know? 20.0 The X-axis 20.0 the ZX. So I just fine-tuned my 3d printer, even a bit more. The difference between this cube and this cube wasn’t that big 0.1 is 90.9 But now I fine tune this even more now to wrap up this video. If you have some time to work on your 3d printer and calibrate it so that you have perfect prints, then go ahead. Keep in mind that when you are going to do this, use the calibration cube. You know that the size is 20 by 20 by 20 and then you are going to multiply it by the current steps per millimeter normally on this kind of machines, it’s around the 78 till 80 and the Z height because it’s a lead screw. It’s a different kind of step in my case. It was 400 and I did some calibration on that X as well, so that being said calibrating your 3d printer is not that difficult, it’s fun and you also learn quite a lot about your 3d printer settings, so that being said thanks for watching Please like this video.
