Easel Settings for SainSmart Prover 4030

Absolute beginner here, looking for an easy to understand and use software and I came across Easel. Trying to set it up for my Machine " Sainsmart Genmitsu PROVerXL4030" and I can’t find them anywhere. Rail Size not found, also not sure which motion control my machine uses.
Any help would be appreciated!
Thanks

Did you ever find a solution for this, Been pulling my hair out trying to find the same answer

Record your grbl settings first! It has been reported many times that 4030xl will have ALL grbl settings erased when you go through the machine setup.

It is a best practice to go to machine>advanced and export the gcode and use a dedicated gcode sender like candle, UGS, or Openbuilds to send the gcode with a 4030xl machine
