I purchased my K1C a few weeks ago and have been learning a great deal as I am brand new to 3D printing. I don’t have any functional issues but do have a question. Should my K1C make a kind of knocking sound when it first starts printing and the head goes to the front right corner (where the camera is)? It appears to be checking travel limits or something similar and while it is moving in the “Y” direction, towards the front of the printer, it makes a knock-type noise.
It may have done this since I got it and may be normal…I just can’t recall since so many of the noises are new to me.
If it is like my Qidi printers it will be using the stepper motor resistance when the print head reaches its full travel rather than using limit switches. I would say that it is normal.
I have 3 Enders of various ilks, and I owned a Delta style printer before. ALL of them had the same problem and then solution to knocking… In every case, slightly rising the print head cured the problem, I mean 1/100ths or whatever the tiniest height adjustment you can give it worked for me. Occasionally, I would have to move it 2 or 3 notches. Just FYI
Four printers, four years…haven’t rooted anything yet. The more stuff you change the more stuff that can go wrong. I’m NOT saying that some issues don’t require more drastic changes or methods, but, if it ain’t broke, don’t fix it, As far as raising the head,. here is a response from …X…A.I subset. (my KE is 700 miles away tonight). " To raise the print head incrementally on the Ender 3 V3 KE 3D printer, you can follow these steps:
Access the Control Panel: Use the touch UI screen on the Ender 3 V3 KE. Navigate to the “Control” menu.
Move Axis: Within the “Control” menu, select “Move Axis”.
Select Z-Axis: Choose the Z-axis. This will allow you to move the print head up or down.
Set Increment: You will have options for how much to move the Z-axis. Typically, you can select from increments like 0.1mm, 1mm, 10mm, etc. Choose the appropriate increment for your needs.
Move Up: Once you have selected the Z-axis and your desired increment, you can move the print head up by selecting the “+” or “up” option. This will raise the print head by the amount you specified.
Repeat if Necessary: If you need to raise it further, simply repeat the process by selecting the increment and moving up again.
It’s worth noting that precise movements like these are crucial for tasks such as bed leveling, nozzle cleaning, or ensuring that the print head clears your model during printing. For maintenance tasks, you might want to manually adjust or use these controls to lift the head to a safe height."
I can share that the issue I am having is not related to the height of the head. After more poking around on /r/crealityk1, I found a posting with the exact same issue. What’s happening with my K1C is that the gantry is hitting the end stop when it checks the limit of the “Y” axis. I confirmed this by doing as suggested on this comment and dead silent when homing.
Clearly this isn’t a solution but it did at least identify what is happening. I have contacted Creality and sent them pictures and a video of it happening. If anyone is interested, here is the video.
Please don’t worry, I will help you to solve the problem:
Measure the frame with a right angle ruler to determine whether there is 90 degrees to determine whether it is deformed or not
Check the belt
A. Compare the length of the two belts to see if they are the same, if not, remove them and cut them to the same length (refer to the video) https://www.youtube.com/watch?v=mHyS-xtsnzM
B. Check whether the number of teeth exposed on both sides of the belt pressure plate is consistent, inconsistent reinstallation (refer to the picture)
The belts look good. I also printed a belt tension tool and they are both correct and equal to each other. I need to take the riser I have on the printer off to check for square. However, since the printer is actually printing great, I seriously doubt the frame is bent/not square. I’ll update after I do that.
I will say that I didn’t watch that whole video but even if uneven/wrong length belts were the issue, I seriously doubt I would take on that task on a brand new printer. I would just exchange it.
can you send a video of this noise and make sure it’s a video of the entire process? it’s very possible that you may have a blockage through in the extruder. also what you need to do is run the extrusion process and tell me if you hear a knocking too
Video link was provided above about a week ago. Here is the link again…
Also in that same post, I mentioned that the noise is the gantry hitting the end stop when it checks the limit of the “Y” axis. Doing as suggested in this thread silences the knock when homing…
It does not make this noise when extruding, retracting, or printing. The chain is not coming in contact with anything. The noise only happens when checking the limit of the “Y” axis.
Although I didn’t know when I initially posted, I now know what’s hitting what…just don’t know why or how to stop it. I agree that this issue is not complex at all and I certainly didn’t intend to portray it that way. It seems very rudimentary which is why I’m unclear why it’s not a simple fix.
Oh my apologies, I read this post late at night and def skimmed over it. I dont think you made the issue complex but the solutions provided I think were definetly complex for what (especially after seeing that video) DEF is a simple issue. Im curious though, while you found a solution did you ever manage to find a cause for this issue?
