Anet A8 Z-Axis alignment (Proper z-axis wobble fix and noice reduction)

Sorry for the microphone inconsistency, the only mic I have ain't the best one out there. Doing this with my printer really helped with the Z-axis movement. My printers z-axis stepper motors were struggling really hard when the carriage was at the lowest point and after inspecting the printer I noticed that the z-axis lead screws were being bent because of poor alignment. The brass lead screw nuts were too far apart. Hope I can help someone who has the same problem out there!

Thanks for posting this! I've been trying to chase a problem with the Z-Axis on my new Anet A8 and have not seen this technique yet. This is very helpful.

I'm glad this was helpful!

Adjusting the smooth rods in the x axis wont do much because the zed smooth rods are the constraints for x. Adjusting the horizontal rods do not adjust the space between the brass nuts. Thats all controlled by the zed smooth rods and if the original holes were placed wrong, then the only thing you can do is print a z motor mount that allows the motor to move

Yes definitely release printable files for your robot I would love to print and make it

I know this is an old video, but on my anet a8 it seems the brass threads on the carriage mounts actually measure wider than the z motor centre points, and I've played around with the insertion depth of the x smooth rods, but the z smooth rods constrain the carriage mount width distance. I tried filing motor mount holes into a slot so the motor is mounted relative to the threaded rod which positioned relative to the smooth rods which are constrained top and bottom. Going to have another look at it but with a drill as filing took a long time and didn't get me where I wanted to be

That really sucks, I haven't experienced similar issues with my A8. Hopefully you'll be able to sort it out!

You should fix your audio man. But, your explanasion was on point

Yeah sorry about that the microphone I used for recording didn't really cut it.. I'll definately find a better way to record in the future.
