I will try to post those tomorrow. Bed time for now over here...

Thanks so far!

So I copied the hall and ini file, but I'm on  windows PC right now. I hope this works?

Looks basically ok except that you have "num_pwmgens= 3"
which should cause an error since a 7I77 configuration would not normally
have any pwmgens.

I would disconnect the 7I77 analog out from the drives and monitor
x-output (with halmeter or halshow) as you jog back and forth
and verify if the 7I77 analog output matches x-output
(with a P of 5 you would expect a analog output voltage of 5V per MM
of following error)

Not related to your problem. But I see a small problem with the ini file. Generally the axis and joint should be the same.

[AXIS_X]
MIN_LIMIT = -0.01
MAX_LIMIT = 200.0

[JOINT_0]
MIN_LIMIT = -200
MAX_LIMIT = 200.0

[AXIS_Z]
MIN_LIMIT = -100.0
MAX_LIMIT = 0.01

[JOINT_1]
MIN_LIMIT = -100.0
MAX_LIMIT = 200

We have movement! I must be colorblind. Made a correct wiring diagram but switched the two analog wires like you mentioned. Z axis is jogging between its software limits now. Not tuned yet though. X axis is not moving, doesn't get analog signal. I tried another channel, no change. When I manually put X in another position and I start Linux, X forces itself to 0,000mm on the DRO and stays there. But also no drift anymore.
