Hello,
Since I bought my 3d printer (Tevo Tarantula kit), I am having tons of problems with it.
Now the Y-axis wheels aren’t tight enough, and all the bed is moving. I tried adjusting the eccentric nuts, but it’s not working.
It looks like the holes should be closer to each other.
What should I do now?? Should I drill new holes?!?!
Thanks for helping me (again).
Hello
Hello friends
The best solution IMHO would be to re-drill the holes larger and use those OpenBuilds eccentric spacers - they would allow you to fine-tune the tension in the wheels. I like that many of these cheap printers are built using the V-slot extrusions but none of them use the eccentric spacers despite them costing less than $0.40 each retail.
@Jakab_Gipsz I don’t think I understood. Do you want me to rotate this plate 90°?? The wheels are already too wide, so rotating the plate will make them even wider.
@Petr_Sedlacek that is correct. I also think they should use the eccentric spacers. So looks like my plan is to drill bigger holes.
Not. i delete the post. I see the pictures on the net. The Y stepper wrong side your Y axis, see te pictures.
Are there larger wheels in the kit? Because you may have made little ones.
@Jakab_Gipsz no. All the wheels are the same size.

@1111125 Good luck, should be a fairly easy fix. Just make sure to drill the holes just the right size so that the eccentric spacers sit solidly on the plate.
@Petr_Sedlacek about that, I think it will be too risky to drill only the other side. My measurements show that it will still be okey, and the offset won’t be too big. I hope it would work.
Just a small update:
Finished the drilling work. The heatbed plate is standing still!!
Now I just have to manually level my bed, and clean the workshop.
Hopefully everything will go right.
Wanna say thanks for @Petr_Sedlacek ! So… Thanks for your advice!
Is your tevo kit mostly plexiglass, or mostly 3d printed material. I was just reading about quality control issues with the plexiglass version, and to fix it you should be able to buy a fix-it kit made from 3d printed materials.
@MidnightVisions it’s the plexiglass version, I think I am okay with it. There is no need to replace it or buy any additional kits. Maybe I will try the additional Z rod kit in the future, or create my own one with a stepper motor, laser muchine, and few other materials.
I would replace with a cheap linear rail.
@Richard_Jones Not sure that’s a cost effective upgrade. A cheap linear rail might not be that great and a properly adjusted V-slot slide is very solid.
