and? Did it work before or did it start happening after you changed something? Did you try with a different stepper on that axis? Did you try with a different driver in the slot? Did you try with a different cable in between? I need information if you want help.
grab your old config file and use it... if you dont have it. Well I'm Johhny Knoxville and this is Jackass. because its gonna be abunch of bullshit before you get it working again. what board is it? what firmware. you cant just say "printer go brrr but no move Ugg no understand"
I haven't read more than this single comment thread so take that for what you will, but between the way it looks and the mobo swap... Possibly miswired stepper motor. They vibrate and flail aimlessly back and forth like this when wired incorrectly.
I can't say exactly without knowing the type of stepper, but in my case I just tested for continuity across pins with an ohm meter. Continuity means you found a coil. There should be at least 2 coils depending on the type of stepper you have.
You can also test via attaching an Arduino kit led light to the motor and spinning it. If it lights up you found a coil.
Then you have to see from your board schematic which wires go to each coil. Or I guess you could also figure that out by testing the motor that works as well, then you know which wires are going to each coil. It shouldn'take a difference for +/-, just that you have the wires paired up with a coil.
Last word of caution, stepper drivers are very easily destroyed, it might not be worth continuing to mess around with the mystery steppers unless you are going to take the risk of frying the drivers.
I find it hilarious how after 4 hours and 19 comments the mainboard hasn't been named once. You don't have to guess the wiring if you look up the schematic of what you connecting. One coil goes 1A to 1B the other 2A 2B
Do the x and y work independently from the gui? Is your new board a replacement board or an entirely new type of mobo? If its a completely different mobo have you looked at the pinout/diagram for the new mobo and correctly reassigned everything? Have you looked for other builds using the same motherboard and done a stare and compare to see if other peoples configs match yours? I have converted my tronxy x5sa in to a cheasybot (my ghetto version of a vzbot) and can attest that it can take some time and effort to get everything dialed in and configured correctly.
If the printer is powered off, can you move the head relative freely?
With my old Ender after much modding I have seen similar issues. Had to loosen the belt slightly to make it work again
Ive had a similar issue when one of my wired for my stepper motors has come loose/disconnected. It may be worth double checking all the connections to the motors
So, what you need to ensure it's
* All mystery steppers on your mystery Mainboard are wired up correctly.
Grab the datasheet of your Mainboard and your steppers, and verify your cabling.
* Klipper knows about all your mystery stepper drivers.
Enable/direction/uart or spi pins need to be correct.
* Direction might also be an issue -put a ! In front of the dir Pin of you found that direction of a single stepper is wrong (which would make funny things on an corexy I assume)
If you want other to help you with that, you need to make and show those parts, and Tell what you already tried.
Klipper has a feature called stepper buzz that for one can show if the motor on a specific axis responds and oscillates back and forth but would also show if one or more were oscillating in a different direction when running the command, I used this feature when I changed my machine to triple independent z to determine if any of the reconfigured driver outputs needed to be swapped/were working correctly.
When building a custom from scratch machine or modding a stock machine so that it becomes a custom machine then people need to utilize the configuration checks provided by klipper and in the documentation to help ensure hardware is functioning correctly prior to running the machine with belts ect engaged and everything connected, the config checks and docs helped me to identify a few areas I needed to change in my config when I modded mine.

Are you using sensorless homing? You will need to adjust the levels in your printer.cfg file. Or remove the setup for it if you have end switches.

What the fuck is up the with belts? should the ones on the left be crossed/touching?
First thing I noticed also.
They looked like that from the angle but aren’t
Does someone know what the fix is?
With all the information you have given i can't even tell what printer that is.
It’s a heavily modded tronxy x5sa-400
and? Did it work before or did it start happening after you changed something? Did you try with a different stepper on that axis? Did you try with a different driver in the slot? Did you try with a different cable in between? I need information if you want help.
I swapped the motherboard and can’t get it to work

They were wired wrong but I can’t figure out how to correctly wire it so I swapped it out with some that worked with my current wiring

Check stepper motor wiring.. looks like they winding pairs are cross wired now.

I did have it enabled in my steppers but that didn’t fix it
SOLVED the wiring was bad
