how to enable out6 on 6xd for M569.7 command for brake

Re: How to enable and disable brake on 6xd?
Hi,
According to former post for enabling and disabling a servo brake i tried to assign Out6 on my 6xd board to the brake of my servo P0.0 with following command:
M569.7 P0.0 C"out6"
when i later use the command M569.7 P0.0, it seems it doesn't do anything on port out6.
I would expect the port out6 to read 12V.
I connected out6 to an ssr which needs between 4V and 30V input to open. The output is conected to 24V which is needed to open my brakes on the servo.
Am i doing something wrong?
firmware of the 6XD is 3.52 -

@lazy_mosquito I could be wrong about this, as I haven't used the brake function, however I would expect the brake output level to change when you run M17/M18, not when you run M569.7 again.

@Maestro Thanks,You were right M17 did it, but it didn't solve my problems. Even if i unlock the brakes, i am unable to move the servo because the duet3d firmware doesn't let me move any servo before i home everything. the problem is that i have to tune my servos before i can home anything. And for the tuning i need to move my servos. chicken egg problem.
The command M564 S0 H0, which should enable moving the servos before tuning is not allowed on deltas.
Any way how to move my unhomed axis on a delta?
Maybe better to change the title of the topic, How to move stepper or servo without homing on delta? -
@lazy_mosquito if you set axis positions with G92 the axes become homed.

@oliof i don't get the homing error anymore, so i would think it works now. The moment when i move my z-axis 100 up with the command G1 Z100 F300 nothing moves, but the webinterface says now the z-axis is at 100?
Something is completely off, but i have no idea what.

@lazy_mosquito I wouldn't slap the G92 into config.g, just emit it on the console with the effector in a well known position so tuning can happen
