I’ve recently put together my K8400, and everything was working smoothly.
But I got one bad print (large amount of tangle and a large melted blob). But I removed all the filament easily. However, now it makes a “brr” sound and the y axis moves with a lot of resistance.
I greased it and it worked a lot better, but still not good enough to actually print anything.
Everythibg gets displaced while printing. Each layer moves about 3mm to the right, making each print look like a “staircase”.
Any thoughts on how to fix?
Most certainly the cause is a misalignment of your Y axis. have a look at the [color=#408040]Wiki [/color]about this.
