🤦♂ Resolved: X and Y swapped movement
Slowly working on commissioning. All 3 Z motors behaving correctly. And the A and B motors do move in the +/- directions correctly, but when I click Y+ it moves the toolhead in a X+ direction. And visa versa with X and Y.
This is my first CoreXY so I am no doubt the problem here.
I have tried (separately testing each time):
- swapping the X and Y (a and b?) motor plugs at the drivers.
- in the printer config (!) reversing the direction pin for X and Y motors.
- in the board (Spider2.3) cfg swapping the X pins with the y pins definitions.
All these produce is reversing the direction of an axis movement, not the axis’ themselves. This seems like a 101 derp moment because I don’t quite understand core xy movement yet. What am I doing wrong? ✌️🤦♂️

Try reversing the pin direction for only one motor
This. Try around with swapping the motor directions via config, theres only 4 possible combinations. One must work.

Yeah, reversing one direction should work, but which to reverse will probably be easiest figured out by testing.
Just to make sure:
plug in the left motor (seen from the front of the printer) to the 1st slot on your board (X) and the right one in the 2nd (Y).
And of course write your spider2.3 cfg the same way.
Physically switch the connections for A and B motors
Thanks guys. Nothing worked. Then I found this… 🤦♂️
Sorry for the runaround.
