Using TMC2209 drivers on an Octopus motherboard with a full graphics smart controller. Machine is custom made coreXY. Have tried the latest bugfix version and also a couple older versions of Marlin. New machine build so this isnt something that was working and now is not.
Sensorless homing works as expected if I click AUTO HOME on the display menu.
Does not work when a G28, G28 X or G28 Y is issued from G code on a SD card. Instead the machine will begin homing X and or Y and will vibrate the motors when they physically run up against the rails but will not home. If I home manually using AUTO HOME then print from SD without a G28 X or Y in the G-code it will home Z using G28 Z in the G code and will print fine. Then when the print is finished if I click on AUTO HOME it will not successfully home. After resetting the controller it will home with auto home again.
Bug Timeline
not sure. New machine build
Expected behavior
When the machine is given a G28 command from the G-code file it is running it should home XY then Z axes.
Actual behavior
When the machine is given a G28 command via G-code on the SD card reader the machine attempts to home X and Y axis but does not sense the stall and does not complete the homing sequence. However if the machine is homed using the AUTO HOME command from the UI display menu it will home as it should.
Steps to Reproduce
Compile and load latest Marlin 2.1 or 2.1 bugfix.
Home machine using AUTO HOME from the UI. Machine will home normally.
Run a G-code program which contains a G28 from the onboard SD card. Machine will attempt to home but will not sense the motors stalling and will continue turning motors.

I have other printers using this same electronics setup only are not coreXY kinematics. They do not have this problem. I have tried using the same Marlin version as some of my other printers which are not coreXY and the problem is there only for coreXY.
Did you test the latest
bugfix-2.1.x
code?Yes, and the problem still exists.
