Nvm i found it, forgot they were archived! https://discord.com/channels/582187371529764864/844167067757182980/998324814509002944
yep, didn't have time to move this to the new forum format

well I have a very intresting problem now
I thought the wiring like you had in your picture for X and Y, but now my printer when I go to the consul to move X it moves Y so what I assumed was to flip the wires, so that X would move X properly and Y moved Y properly, nothing changed, and what happens now when it goes to hit An in stop, the printer doesn’t even stop. It just slams itself into the endstop and keeps trying to move, Like the endstops work but it’s like they don’t even read it? I’m useing a Manta m8p @elcoj

I'd guess that it's only looking for input from the X endstop while moving on the X axis. There's a chart somewhere about flipping pins to make the movement go in the direction you expect, I don't recall where. It's either swapping ports or inverting things in printer.cfg
foreign-sapphire•2y ago
But even when I set the kinematic position, when I press the arrow to go right on the x-axis, it goes back on the Y axis? Get what I’m saying ya know?
Did you forget to invert the direction pins?
foreign-sapphire•2y ago
No. I didn’t
Didn't forget?
If you flip the motor pins, it inverts the direction. So you need to invert the dir pin too.
foreign-sapphire•2y ago
I did-not forget
And only flipped the pins on one side of the cable?
foreign-sapphire•2y ago
I flipped the pins on both sides
Guess I should of payed attention
Sorry
And you expected that to do anything except changing your wire colors?🤣
foreign-sapphire•2y ago
I don’t understand
equal-aqua•2y ago
Just to clarify, did you change the position of two pins, or 4 pins (or 8 pins)
It's just on one side 1234 to 4321
foreign-sapphire•2y ago
8 pins
Each side
Ohhhh
Gotcha
equal-aqua•2y ago
😅
So each motor pin is still connected to the same driver pin
foreign-sapphire•2y ago
Yeah
foreign-sapphire•2y ago
No not at all. (Yes) just kinda stupid ya know
Lolll
equal-aqua•2y ago
I might do this now since I'm tinkering with my config too anyways...
Man I wish I had your skill depinning, mine are all JST connectors that don't have the easy plastic tab to lift and instead have to press the metal insert down 😅 , doesn't go so well.
Gonna swap them around on the stepper side, it does appear to have the little plastic tabs to lift.

Also does this apply to Z motors? Z seems to be the loudest, but I assume that's coming from the actual bed moving/etc
Yes
But also align your lead screws and lube them
After adding top constraints, reseat the coupler by loosening and fastening
Motor side is easy with a small knife
equal-aqua•2y ago
Ah, I don't have top constraints (3.0 build didn't have them)
foreign-sapphire•2y ago
@elcoj switch the bored side back to the normal wiring diagram, still its moving flunky
x moves y, y moves x
equal-aqua•2y ago
did you plug them back into the wrong ports
If you plug your X motor into the Y port, and visversa... it'll do that
foreign-sapphire•2y ago
No
I even flipped them to check @apple.sauce
equal-aqua•2y ago
Did you forget to flip both x and y in the printer.cfg? Or the wires on one of them?
Check your wiring again against your board's documentation on the ratrig page
foreign-sapphire•2y ago
What is there to flip in the cfg?
No
equal-aqua•2y ago
You need to invert the pin for the motors so they turn backwards now
Since you've crossed the wiring to be backwards.
foreign-sapphire•2y ago
Oh well yah i did that
But i dont understand how x can control y, vice versa
equal-aqua•2y ago
Because of how corexy works
To move in X axis, both motors have to spin.
Google suggests that you need to reverse one motor in a CoreXY to flip X/Y
foreign-sapphire•2y ago
So what dose that mean
equal-aqua•2y ago
That you have a wiring problem
Or a config problem.
I suggest you re-check:
1) Did you correctly reverse both sets of X and Y. Does the wiring order on both stepper ends of the cable match, and does the wiring on the opposite ends match each other
2) Check that they're plugged into the correct board per the wiring diagram
3) Check that you inverted both of them in printer.cfg with a "!" (or by removing a ! if you already had it) and that you didn't accidentally invert a Z stepper via the printer.cfg or something.
foreign-sapphire•2y ago
Yes i think i found the problem
one momment
@apple.sauce I fixed it, WOW DOSE THAT MAKE A DIFFRENCE
Why would my bed heater just stop heating?
Like i have been printing fine all day
Please don't rename a post and change the subject. It makes it confusing for people in the future doing searches. Why don't you start a new post specific to your new problem?
foreign-sapphire•2y ago
Okay I will .

Hi, I have the problem with Stepper buzz. I tried everything I read about. Flip the wires on one side, changed the stepper driver, lower the run current and bought new motor cables. Nothing work. Btw i use 5160’s and ldo 42STH48-2504AC. Sorry for my bad English tho 😅
