New forum member needs help to get startet with LinuxCNC

Hello everybody!

I’m new to this forum and new to linuxcnc.
I own a 3-axis gantry mill that I used to control with mach3 connected to a USB Motion Controller.
The controller died a while ago and since I didn’t have any milling projects the machine has been sitting in at the corner for quite a while.Recently I decided to bring it back to life. The goal now is to to get rid of Windows and USB. I got a 7i92 Board that I could bring to life. I have installed linuxcnc from the latest available .iso file. In addition I have a WHB04B Pendant available, that I would like to integrate.
Linuxcnc is not very intuitive for a beginner, but I managed to get it working to some extend. I used an „axis“ configuration and could connect the pendant, I got to a point where the display on the pendant was updated when I moved the axis in linuxcnc and keypresses on the pendant showed up in linuxcnc, so the hardware/config is generally working, but I never got jogging to work. By now I have obviously tried too many things and messed up the configuration in a way that it is not working at all any longer.
To have a clear and clean configuration to start with, I would to prefer to restart from scratch.
So my question is:
Is there any HowTo and are there sample configurations that include the WHB04B?
Since I’m new to the world of Linux I assume the learning curve will be very steep.
Thanks in advance for your support!

P.S.
If this leads to success, I’m happy to log the details and to compile a step by step howto for beginners, since I couldn’t find any.
