Afternoon everyone! I recently purchased an SV06 Plus ACE and I have been having mad vibration issues throughout my time owning the printer. I went to check the smoothness of the X and Y axis. my Y axis rolls perfectly smooth but my X axis seems almost gritty? I thought it was the belt but after detaching that from the head assembly it still felt wrong. I then took the print head carrier off of the X rail and all of the bearings seem to roll smoothly. if I remove one of the bearing and kinda of hold it in place it rolls perfectly fine but then as soon as I put the third bearing back on it rolls like crap again. I would attach a video but since I am new I am unable to do so.
If you bought it from Sovol, email them about your issue at info@sovol3d.com
If you bought it from somewhere else, you will have to email them.
While you had the 3rd bearing out, did you try to lube it..??
the bearings seem to be sealed so I didnât really know how to go about doing that however they also feel decently smooth when I spin them with my hands
Update for anyone else who may run into this issue with this printer. The bottom roller bearing can be adjusted with the wrench supplied with the printer while the hot end is assembled. just turn it either direction until it feels smooth. I would suggest disconnecting it from the belt for this but you really donât have to if you donât want to.
Ah! I had the same problem. Thank you for the great lead. Just to clarify for anyone else: The bolt is 10mm, and is already set with a nylon nut, the mechanism is usually referred to as an âeccentric nutâ. Youâre not looking to tighten that nut; Your aim is to simply âpointâ the bolt in the correct direction. As Playin_On said, turn it in small increments (think of it like a clockâ10min intervals), and roll it back and forth slowly, with consistent force until you pinpoint the best direction and the carriage moves freely, and consistently.
A method I used to make this easier is to put a small line onto the nut with a marker to keep track of the direction. This allows you to quickly assess whether the eccentric nut is not at the right âtimeâ.
Mine was fine my first couple weeks printing, but at some point I noticed growing Z banding like imperfections, and it had shifted mid print a couple times, eventually I noticed the growing loudness as it traveled along the rails. This completely solved all the problems I was having, but I did notice the eccentric nut was nearly too easy to turnâlike I could have turned it with my fingers if I tried. I assume this contributed to it going out of alignment after some time.
I believe having to actually tighten the nylon nut to the bolt would be the real solution, but unfortunately I assume this might happen again, so keep an eye out for it on your printer!
Iâm gonna be honest I didnât even think about that but that is a fantastic point. Definitely gonna tighten the nylock nut now after verifying it hasnât loosened or tightened just to kind of lock it in place. Thanks for adding this.
Thanks for sharing, encountered this same issue here today.
