Description
Did you test the latest bugfix-2.1.x code?
Yes, and the problem still exists.
Bug Description
I was playing around with my Marlin Configuration (bugfix, latest build) for my Ender 3 Pro and had something very strange happen.
When I would issue a G28 (HOME), the hotend and bed would move at normal speeds getting to X=0 Y=0, but then going towards the center, the bed and the hotend moved very slowly (I could hear the stepper clicks) [This can be seen in the video Ender3Slow].
If I move the hotend (not using G28) it moves along the X axis at normal speed (see file Ender3Normal).
I was wondering if anyone else had something similar happen, or can point me to a direction to fix this.
The videos and configuration.h, configuration_adv.h are in this dropbox location:
thanks very much!
Bug Timeline
Started happening this morning
Expected behavior
I expected a faster speed going towards center of bed, and downward Z movement to get bed location
Actual behavior
Homed to (0,0) at normal speed. Then going to center of bed, the x and y axis movements were slow, and the Z axes did not lower towards the bed.
