Geeetech

I have the Geeetech i3 pro B. I have constructed it, and it appears fine.
I am completely lost when I try to work out how to work the machine. The user manual starts with Repetier- host, but when I installed this, the Printer settings has a warning: 'Notice: you have a Repetier-server installation. We highly recommend using the Repetier-Server connector instead'. I've followed the instructions but I've clearly done something wrong because the Notice has not gone.
So - I joined the Forum, and here there isn't a Repetier section, but people seem to use Easyprint.
What do I do? Is there a beginner guide somewhere?
Thanks
Paul

Skip Repetier for now and start with another slicer, for example Prusa Slicer.

You can find my configs for it here.
These I use on my Pro B and they work well. Perhaps you like to tweak them a bit later on.

Slice, and transfer the g-code on an SD-card is easiest in the beginning.
Later on perhaps you could set up an Octoprint server. Really makes things a lot easier.

Good luck
