Anyone know about updating marlin firmware for Prusa i3? I don’t have the source code (configuration.h) so I was going off of YouTube instructions among others. Everything is working except for the Z axis control, which makes a loud noise when moving in either direction. I’m thinking it’s the axis_steps_per_unit that I don’t have the right value for, but it could be other things that I haven’t considered yet. Any help or ideas would be great. The value that makes the least noise is around 4000. I tinkered with it in both directions and it only seemed to get worse.
In the example picture the value works out to be 2000 (200*8/0.8)*1.
Thanks.

This is the guide I used when I upgraded to the MK2S. Didn’t have any issue. Do you try these steps?
Thanks guys, I got it sorted out with a z-axis step calculator and the magic number is 2560.00. My printer isn’t an MK2 so it’s not very nice, but provides a great learning experience, figuring out the “inner workings”.
Oh sorry. All the MK2 post recently I kinda just assumed.
No worries my friend. Thanks.
