Hybrid confusion
Installed belts today for the hybrid and used configuration setup to be 500 hybrid. thing makes a awful noise as you can hear belts skipping.
My printer.cfg reads
[stepper_x]
dir_pin: !x_dir_pin # Add ! in front of pin name to reverse the direction of stepper_x
rotation_distance: 40 # 40 for 20 tooth 2GT pulleys, 32 for 16 tooth 2GT pulleys
homing_speed: 50
position_min: -59.8
position_max: 559.8
position_endstop: -59.8
#---------------------------------------------------- X1 ----------------------------------------------------
The B axis motor for the toolhead, located at the rear right of the printer
#------------------------------------------------------------------------------------------------------------
[stepper_x1]
dir_pin: !x1_dir_pin # Add ! in front of pin name to reverse the direction of stepper_x1
rotation_distance: 40 # 40 for 20 tooth 2GT pulleys, 32 for 16 tooth 2GT pulleys
#---------------------------------------------------- Y -----------------------------------------------------
The left Y motor used for cartesian Y control in Hybrid CoreXY, located at the rear left of the printer
#------------------------------------------------------------------------------------------------------------
[stepper_y]
dir_pin: !y_dir_pin # Remove ! in front of pin name to reverse the direction of stepper_y
rotation_distance: 40 # 40 for 20 tooth 2GT pulleys, 32 for 16 tooth 2GT pulleys
homing_speed: 50
position_min: -14.35
position_max: 530
position_endstop: -14.35
#---------------------------------------------------- Y1 ----------------------------------------------------
The right Y motor used for cartesian Y control in Hybrid CoreXY, located at the rear right of the printer
#------------------------------------------------------------------------------------------------------------
[stepper_y1]
dir_pin: y1_dir_pin # Add ! in front of pin name to reverse the direction of stepper_y1
rotation_distance: 40
which makes no sence to me.

After troubleshooting turns out I have a bad motor. will wait till replacement arrives to finish hybrid upgrade. Thank you to the folks that helped me get to the answer.

drop your debug.zip in here and maybe a video
@TheTik Video I can do. Is debugging on be default?
I think the debug.zip is always available. There is additional debug lines generated if you change some settings but shouldn't be needed for this
My best guess is that one of the two motors on one belt is turning the wrong way
That’s what I thought as well. I just didn’t know why 3 would have ! And one wouldn’t. I don’t want to damage belts already enough damage today.
look up "stepper buzz" and buzz each motor to make sure the go in the correct/same direction and the correct motor moves
Looks like y1 not responding
that'd do it
