charred fulcrum
Good afternoon everyone, i hope you had a great day till now, i hope you can help with the problem and thanks in advance!
My anycubic kobra max is running on and off, since around a year and now it started being super loud while printing. It narrowed it down to the feeder/ feeder retracting filament and i tried lubing it and cleaning the feeder with acetone, but nothing helped.
Does anyone know what i could try next, because i cant print with it being that loud.
kind regards, jim

thanks for your response, unfortunately after trying increasing and decreasing tension, the problem is still persists
charred fulcrum
Increase idleram tension. If it gets worse lower it
you got any other ideas?
should i just try getting a replacement gear? i seen somewhere that those wear down over time, maybe thats the problem?

ITS THE MOTOR ITSELF
charred fulcrum
do you know how to fix a stepper motor?
charred fulcrum
There are no stupid suggestions, but already tried that
charred fulcrum
Stupid suggetion
There is realy just the option to replace it, huh?
honest path
Im still a little sceptical tbh because i think in 8 years i broke 1 motor and that way by frying it with 220vac by accident
You sure there isnt a loose screw ratteling

i am rather confused as well and i never thought it would happen, but i let it run outside the printer, and it just makes noise on higher speed, like when pulling out filament
honest path
if you unscrew the motor and let it run does it still klick`? maybe video it again

i really highly doubt the motor is actually the thing that might be fried if anything fried its the stepper driver.
on a stock board i can see that happeneing, not on a 3rd party board, well possibly but with a very very low chance.
honest path
I thought of cable maybe because that can make all of funny things
charred fulcrum
i gonna send a vid later (i also think its weird, especially since he is still working but REALLY loud, so he is not fried, just weird)
agile jetty
which firmware did you install on the board?
charred fulcrum
it is stock
did not change much about the printer except replacing a broken resistor a couple weeks ago
its the 2.8.6
agile jetty
sorry for some odd reason i thought you messed with the vref must have been another post.
marlin? from anycubic
charred fulcrum
the stock official anycubic kobra max 2.8.7 Firmware from the website
agile jetty
ill take a look. i doubt its firmware related but nots rule something out.
charred fulcrum
i can send in around 2 hours, i am in class right now
honest path
Have reseted the epprom via pronterface? Oh and it would not be the first kobra i had to install firmware 3 to 6 times for it to actually work
agile jetty
yeah they are using some wierd combination of closed marlin firmware which is wierd since license wise they need to opensource their firmware. they are also using a chip on that board that has no marlin compatibility. they did something super wierd.
