Orthogonal 3d printer is one of the most satisfying and frustrating procedures. Not necessary unless it's necessary. :)

thanks，this is really helpful. and for one motor one belt moving，is it good of 2 peaks in gragh？

oye que buena idea, pero y el linear advance? tiene que ir acompañado del input shaping.

this video is educating af! thank you very much. Small question to the diagonal movement for Corexy. Is it better to run 0° infill instead of 45° to run both motors and belts?

Hi, first of all thank you so much for this nice video. It explains a lot..... But I have one question though. In minute 22:29 you explain that usually the X has an higher amplitude than the Y Axis. This is not clear to me since X has less mass. I'm using a Creality K1 Max and in all my diagrams actually the Y amplitude is higher than X. If you are really right than it would mean that my X-Axis (and probably the X-Axis from many other users) is overdamped. Could you confirm that you described it right?

I just want to say thank you for this video! I helped me figure out that my machine was not sitting perfectly flat on the surface I moved it to after building! My graphs on x were 100% indicative of having a wobbly table or the machine moving around. After repositioning the machine the graphs are pretty dang clean now! THANK YOU!

reached to 0.2 deviation on my 500mm bed. thanks a lot ! :) ( also with some kapton tape at certain areas ) . but I couldnt figure out that I should lower B to side to increase the distance at C. Thanks!

What is the method to understand what physical points "A,B,C,D" corresponds to the virtual bed mesh? For example how do I determine what point is physical point "A" when looking at the bed mesh?

@markleaf1970 Жыл бұрын

When you look at the heightmap generated in RatOS, the position x=0,y=0 is A, and position x=300,y=300 (or whatever size printer you have, this is for 300mm) is C. So basically the origin 0,0 is at the bottom left corner which is A. After homing in the dashboard of RatOS you can move the print head to any location to know where it is physically as well if you are still having trouble.

I just made a funny discovery on my Printers. they are both standing in a not very rigid ikea shelve and when looking at the heavier exis of my two completely different printers, the peaks were at almost identical positions, just heavier on the one with the heavier gantry. It seems like i just found the resonant frequencies of an Ikea shelve xD

@DesignEntity Жыл бұрын

The opposite does not seem to be working. If I try to raise D by elevating A, then D does not move but A does.

This is amazing, thank you very much for this intro. It’d be nice to have a video with how the input shaping evolved and where it came from.

@scottwillis5434 Жыл бұрын

I appreciate the video, very helpful! 7:50 isn't the change in Z height (1 - cos(phi)) * 500 mm? The layers would be skewed relative to each other, by sin(phi) * layer thickness for each layer, by sin(phi) * 500mm maximum. This would be quite subtle. That's if all the Z axes had identical, parallel tilts; otherwise that turns into a mix of the center of the build plate shifting sideways, rotating and tilting.

HI. If you have loose screws/bolts can you say roughly whether it is the frame, XY gantry or print head? According to your video, I have a small peak in Y before normal and in X a very small peak after normal. When I compare it to your video, it's "loose bolts" every time.

Great video! Hope the series continues soon 😊 I have issues with my printer and I can narrow it down to a loose bolt and a wobbly table. The latter I’m aware of as I placed the printer on such a tabel To work on. However I’m not sure where to look for a loose bolt or even what is defined as loose? Like what torque is needed to tighten the gantty parts, mgn rails etc… Do you have any pointers, please?

@mikev4558 Жыл бұрын

love your video. one thing i don't really understand is the "over-dampening" isuue. What do you mean by this? can you give a few more examples. i though dampening was a good thing, as dampening absorbs resonance and converts the virbration energy into another form like heat. hence reducing resonance virbations.

@3dprintersawhiteboard401 Жыл бұрын

Think of the following example: We think of a linear oscillator mostly here. A very easy example is a spring with some weight attached. Now think about the spring being in a liquid, which will be dampening. We want to move the weight by moving the end of the spring. Now think of a second spring attached to the same weight, perpendicular, but with different length of the spring. If the liquid is very viscous, it will start delaying the movement of the weight. So if I pull on both springs at the same time, the weight will move in a bow instead of a line. Now, of course we can argue that this happens anyway with different lengths of the spring, but I think you can get the point. Over dampening has bad influence on the acceleration and deceleration phase and will create something that looks like overshooting in the corners. Worst case would even be, that it eats some tiny movements. It also stretches the belts and therefore reduced the lifetime of both belts and pulleys, and can also create belt artifacts when the teeth start to not perfectly fit the pulleys.

@TommiHonkonen Жыл бұрын

i mighta have to take out some bolts on the x axis rail at 21:50 innit the deviation more than 0.2, the scale is not on, the high is just about 0.2 and low is clearly below flat plane. you are looking at like 0.3 or so. i did a mesh just to check, mine is 0.4 or worse on a 500, bowed af but might try to fix that by letting some bolt go on the a axis.

Yes, depending on the state of the frame, it can make sense to use the other corner in the opposite direction.
