Marlin: Z-Probing fails after turning on ATX PSU

[uuzi]

Bug Report

• Description: After issuing M80 to turn on my ATX PSU, the first homing (and only the first, second try is perfectly fine) works ok for X and Y but for Z it just moves along the X axis to the middle and stays at the Y-min position.
• Expected behaviour: Hotend should move to middle of bed for Z-probing

Just to emphasize, this ONLY happens on the first homing after I turn on the PSU. Every homing try after that works just as expected, until I turn off the PSU again. After that the first try will fail again.

Does it make a difference if you switch the power supply or if you just reset the processor?

Here was my workaround. Put it in your start gcode before homing:
G0 Y1 ; TMC2130 Y-axis workaround

strangely enough, that works. so there is a bug in the tmc2130 implementation?

It is already fixed in the bugfix1.1.x branch.

Please test with the latest bugfix-1.1.x (and/or bugfix-2.0.x) branch to see where it stands. If the problem has been resolved then we can close this issue. If you still see the bad behavior we should investigate further.
