I have two Creality HI machines, and one works without problems, while the other came with ghosting right out of the box. I tried several things, and the only thing that significantly reduced it was downgrading to version 1.0.38 and recalibrating the input shaping. Did that fix it completely? No, but it helped. Creality needs to listen to the community and solve this problem because some machines come with a certain build quality and others are different. It can’t be that two machines purchased in the same place, which appear to be exactly the same, print differently despite the calibration efforts made by the user. It is not true that this machine competes with the Bambulab A1; it literally does not even reach half of the strengths and print quality that the Bambu has. It is a product released in its testing phase.
I’ve got 3 Hi’s and all 3 have horrible ghosting. I had one that worked perfectly but it died after only 8 days so I had to get it exchanged at Micro Center. Now the new one has horrible z banding issues and ghosting. I’m probably going to take this one back soon since Creality doesn’t know what’s causing the issue.
First, you need to check what frequency and what type of shaper is set after calibrating the input shaper. I have zv 29.6Hz for the table, ei 42Hz for the X axis. The echo depends very much on the belt tension. Most likely, your belts are either too loose or too tight. I will also say that it is better to print perimeters at accelerations up to 3000 m/s². When I adjusted the belt tension, I had either a strong or weak echo. Also, during calibration, the printer should be on a table that does not vibrate, or even better on the floor. Otherwise, the accelerometers will remove the wrong resonant frequencies.
I am experiencing the same problem with the creality hi printer. It violently shakes as if it is an earthquake directly under it. Now before I replied here I checked my setting for any thing that says “frequency” or “shaper”. And I see no such thing in the settings or any where else. I do not know if creality has this issue on a high priority to resolve, but they need too. Because I plan on purchasing more printers but I wont until this is solved. Because the shaking knocks over the whippers tower leading to bleeding or colors spot into the models. It also breaks supports that are needed to complete my models. I am currently trying to print a helmet & not even half way through and the printer is already violently shaking leading to visible distortions in the wall patterns. Can anyone provide an actual resolution b/c I have already turned down the X/Y jerking before this problem began.
Having the same issue too, and also frustrated on the radio silence about this and the printer in general. Even now long after launch, the only vids that hog any search, are the original review vids etc on YouTube.
Back in the Ender 3 days, you’d have 100 vids by now, showing how to test, repair, fix anything and talking about all the issues.
My surface quality is very poor - waves and patterns all over the place. It is like resonance compensation just isn’t functioning at all. I’m seeing more and more people talk about it on user groups, pictures of parts identical to what I am getting, but mostly being dismissed and nothing on YouTube that I can find relating to it.
To make matters slightly worse, the only suggestions you get are from people who don’t seem to have the issue, and it’s things like “run a temp tower” and “calibrate flow”
Yeah, very helpful. I didn’t just enter the printing world when these supposed “out of the box” printers launched 10 min ago lol.
@nacod3d Well no screw has ever broken on me, I recently updated the firewire. And it look as though they have figured out the printer head shaking. Why because my current print of a helmet is pass the 700 layer and the printer head is no longer shaking
