X and Y vibrate and move erratically when moving to the Z safe homing point
X,Y, and Z all move smoothly when moved individually.
X and Y both HOME smoothly
The problem occurs when X and Y move from their home positions to the SAFE_Z_HOMING_POINT
ABL is in Bi-linear mode and works pretty much as expected.
SKR 1.4 Turbo
TMC2209 Stepper Drivers Diag. pins removed. Mechanical Endstops for X and Y min
BLTouch ABL Endstop fro Z Min
Steps to Reproduce
Initiate "Home All" from BT TFT 24
Expected behavior:
X Homes to the Mech Endstop in the min. position
Y Homes to the Mech Endstop in the min. position
Z moves diagonally to the Z_SAFE_HOMING_POINT (roughly the center of the bed)
BLTouch deploys
Z homes to the build plate until BLTouch triggers
Actual behavior:
X Homes to the Mech Endstop in the min. position
Y Homes to the Mech Endstop in the min. position
--> X and Y vibrate and move erratically towards the Z_SAFE_HOMING_POINT but never fully make it.
--> The Main Screen on the LCD Displays the proper X and Y position
BLTouch deploys
Z homes to the build plate until BLTouch triggers
Additional Information
Lowering XY _HOMING_FEEDRATE (20*60) and raising HOME_BUMP_DIVISOR (5,5,2) help.
If I physically push the X and Y carriages they will move to the Z_SAFE_HOMING_POINT
Junction deviation is set to 0.013 by default. (I dont understand this one yet).
Please let me know what additional information might be helpful?
