Problem: Curious Axis Behavior (FluidNC 3.9.1) #1385

Interesting: issue on 2 different ESP32 exactly the same, when i fall back to 3.7.11 everything is working without problems! $SS |
My first guess would be it has something to do with the SPI stepper drivers used with a I2SO cs_pin. Many changes to I2SO have been made in recent revisions. I am on vacation for a few weeks and don't have access to a 6 Pack with SPI drivers. I may be able give you some things to try, but I cannot test. |

What happened?
Updated the Firmware since 1 Year now i have Problems with Axis Movements.
After Startup: JOG Mode: X,Z,B axis won't move in any Direction (Log Console showing normal)
Y,A and C Axis Move normally
.
Switched off Powersupply for 6 pack board, waited 1 min,
Switched it back on: X, A, C Axis are Moving without problems (Jog-Mode),
previous Problem shifted to Axis Y,Z,B...
Test:
Reconfiguration from StealthChop to Stallguard on all 6 Axes (Run Mode):
same Test revealed that all Axis wanted to move, but the Axes with the Problem are just "squeeking" the Time the jog signal is on.

Other Information
before Updating to 3.9.1, everything seemed ok.
TMC Drivers Swapped without any change of the Issue.
in StealthChop Mode, Axis that will not move are silent.
in Stallguard Mode, Axis that will not move are "squeeking" during movement tests.
Axis Behavior is different, sometimes X,Z,A are not moving... sometimes Just Y,B are not moving
Axis that move are perfectly fine, no mechanical issue.
