Ok!

Aber was könnte man direkt nutzen ohne zusätzliche hardware? Direkt am rpi4?

Danke

The translation into English is:

"Is the 7I92 pin compiled as:

10 30 IOPort SSerial 0 TXData0 (Out)
11 31 IOPort SSerial 0 RXData0
?

The translation into English is:

"Do I only need this HAL configuration:

loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=1 num_pwmgens=1 num_stepgens=5 sserial_port_0=0xxxxxxx"

Or are there other settings required as well?"

I'm trying to decide on a connection for my satellites

Ethernet or Firewire Cables, 5V or 24V ?

* RJ45 is cheaper, but could be confused with Ethernet
* FireWire uses thicker cablesCheaper
* satellite boards can be built using 5V, but 24V is practical for many sensors and limit switches
* RJ45 and 5V are compatible with Mesa-SmartSerial (except for the firmware)

Does anyone have any ideas?

no, but you can see the new pins with:

halcmd show

Hello, I'm trying to clone this board. Do you have any HAL file references?

See

benötigt aber noch einen usb-blaster zum programmieren.

Screenshot of the settings page?
In the meantime, disable:
-auto volts
-void sense/void lock
-set the arcok high to 160V
-set the arcok low to 60V
-set VAD to 60-65%
-set the cut voltage to (in your case) 100V
-set the feed rate to 2000mm/m
-set the jog speed to roughly 2000mm/m
-press F9 to fire the torch
-press an arrow key to jog
-watch the LED's on screen for arcok/up/down
Material for testing, 2-3mm thick, current set to 40-60A
Make some test cuts, check the under side of the cuts for dross and how easy it is to remove it, adjust feed rate/ air pressure (only while air is ON) and cut voltage till you get nice clean cuts with little dross.

It has somehow to do with the enabled stepper motors. As soon as the drive gets the enable signal the pins don´t change anymore (viewed them in hal config). Wen i check with the multimeter, the signal seems to be switching between 0.2V an 24V correctly (both with stepper enabled/disabled). Maybe it is an issue with those cheap breakout boards ?

That is almost always an interference/wiring/grounding/shielding issue, and cheap BOB's with optocouplers are very slow so will limit speed a lot, the ones with input buffers should be OK.
But, 24V? What encoders are those?
Upload some pictures of the wiring here so we can have a look.

That is a version of BL-Touch sensor for 3D printers, usually 5 wires, +5V, 2XGND, sense pin and a servo pin that drives the sensing bit up/down.
Should be pretty easy to make it work, the "push sensor down"/"pull sensor up" logic should be similar to RC servo, but i never bothered to check, despite having several in use on Voron's i built.
Precision is quite high and temperature drift is quite low, but i doubt it is precise enough for a mill, should be more than enough for most routers.

Colleagues, here is a device. Electrical connections: 5 wires. 
Connector: 5-wire, compatible with BLTouch:
    Black — GND (ground)
    Red — +5V
    Yellow — Servos (rod control)
    White — Probe (output signal)

Has anyone tried this? I'd love to hear about your experience using it as a probe. The ad highlights a very appealing feature—the
trigger weight is only 5 grams.

As I said, change of workpiece length, or as you say, change of depth.

Found this post,  sounds similar to what you need.
