Describe your issue:
Problem is when I stepper buzz x or y both x and y move. All other steppers, z, z1, z2, z3, buzz correctly.
I have reinstalled klipper from scratch, tried a CM4 module also installed from scratch.
The printer.cfg Im using has only the x, y, z, z1 drivers used, I attached it so you could see how I swapped the drivers from x, y to z, z1 as described.
Last thing I tried was to swap x and y with z and z1 in the printer.cfg so using the drivers that were z and z1, the problem follows x and y. z and z1 work as expected.
I have been working on this a few weeks with no success, also this is the 3rd printer I have set up with klipper. The others worked fine.
Likely you can spend a lot more time on this without ever solving it: On a CoreXY printer, moving one stepper will always result in a movement of both X and Y axes.
No ;} First thing I checked was the parallel sockets ;}
I went through the pinout several times, and checked by switching the dir_pins to see if the motors reversed and they did.
Also, I re programed the x and y to z and z1, switched the cables and the issue went with the buzzX and buzzY. So using different drivers and plugs didnt make a difference.
Seems as if the step pins of X and Y are connected via software.
So even with X and Y on Z driver ports both react in the same way?
Your config is very simple and not overloaded with thousands of macros that could cause issues.
Are the motors directly wired to the board?
@Sineos already provided you with the correct answer. When you move only the A or B motor on a corexy, the toolhead will move in a 45 degree diagonal direction. That is the expected and correct result. Stepper buzz doesn’t enable kinematics, so you will always get movement in X and Y when doing this.
