Describe your issue: when i try to home I get Unable to read tmc uart ‘stepper_y’ register IFCNT
… again I am super new to this.
now I am getting “Can not update MCU ‘mcu’ config as it is shutdown”
Transition to shutdown state: Unable to read tmc uart 'stepper_y' register IFCNT
It means that klipper wasn’t able to establish communication with the TMC driver for the Y axis. PF13 seems to be the right pin for its uart line, according to the klipper config for the m8p.
Are you certain that you are using tmc2208 drivers?
If that the case you have to make sure that there is a jumper is in this position:
You could try physically swapping the X and Y drivers, to see if the issue follows the driver or is bound to the slot. If it’s a faulty driver, you’ll get Unable to read tmc uart 'stepper_x' register IFCNT instead.
One last resort solution is to remove the [tmc2208 stepper_y] section in the config, but you will lose the ability to configure the driver through software.
This happens when Klipper is started while the MCU board is in shutdown state, from a previous shutdown. Issuing the FIRMWARE_RESTART gcode command should clear that.

How are you providing power to the TMC2208s using the jumper above each of the module sockets:
Sorry if this is a repeat response - I’ve seen a number of people over the past two days with Octopus/Manta boards that aren’t able to communicate to '2208s/'2209s and I’ve found that not providing power correctly to the modules is the primary cause of unable to read IFCNT.

Swapping the x&y stepper drivers did It. They are both working now, maybe I didn’t install them correctly. That is what was keeping my Z motor from running.
I didn’t anticipate that it would resolve the problem; my intention was to diagnose it. It’s possible that there could be faulty connections in the driver slots or a broken solder joint.
I don’t know works now. Can’t get the induction probe to work, but I looked up that it’s not supported with the manta, so I bought a bl-touch should arrive tomorrow.
There is no reason that such a probe should not be supported
