I just ran my unit on v3.7.5 and it works fine.

Sorry for the stupid question, but is main power on? . . . not just USB.

I applied 12v power, no USB is connected. I measured 12.4V between input terminas, however directly on driver there is just 3.06V

OK this is interesting:

flashed - 2nd ESP32 with old "GRBL_ESP32" firmware and motors are working.
switch to FLUIDNC 3.7.5 - motors are working for first time and drivers are initialized :

[MSG:INFO: Axis A (150.000,450.000)] [MSG:INFO: Motor0] [MSG:INFO: tmc_2130 Step:gpio.33 Dir:gpio.32 CS:NO_PIN Disable:NO_PIN Index: 4 R:0.110] [MSG:INFO: X Axis driver test passed] [MSG:INFO: Y Axis driver test passed] [MSG:INFO: Z Axis driver test passed] [MSG:INFO: A Axis driver test passed] [MSG:INFO: Kinematic system: Cartesian] [MSG:INFO: Using spindle NoSpindle]

3. after restart/powercycle  of ESP32 it comes back to error state :

[MSG:ERR: X Axis TMC driver not detected - expected 0x0x11 got 0x0x0] [MSG:ERR: Y Axis TMC driver not detected - expected 0x0x11 got 0x0x0] [MSG:ERR: Z Axis TMC driver not detected - expected 0x0x11 got 0x0x0] [MSG:ERR: A Axis TMC driver not detected - expected 0x0x11 got 0x0x0]

You can send $MI at any time rerun the test.. Try that a few times.

It's interesting even $MI says driver not detected, but axes are moving when 1st test passed

I am not sure what is going on. Both Grbl_ESP32 and FluidNC use the same 3rd party library (TMCStepper) for all motor communications. My 4x SPI Daisy controller always reports on startup an after each $MI.

I initially thought that turn on timing might com into play, but the $MI should not have timing issues because that is well after turn on.

It is possible that the response is more sensitive on your controller. With diasy chain all responses have to go through all motors. Try moving the motors a small amount. If they move change the microstepping and do the same move to see if the setting has changed to move amount.

seems the microsteping has no effect. Looks like motor is moving same amount no matter what I configure.

My personal experience with Makerbase MKS DLC32 v2.1 and three TMC2209 drivers: whenever I add a third TMC2209 driver no one driver is recognized. I solved using a smaller 470 ohm between TX and RX lines. Despite being NOT STANDARD nor referenced on the TMC2209 datasheet, it has been now running since 3 weeks without issues. It sould be nice if someone can double check this behaviour and report back.

I don't think this is HW related, reverted back to GRBL_ESP32 and it works fine.
