Calibration test prints for the J1/J1s 3D Printer

Can anyone tell me how they go about dialing in filament with these printers? I hoped there would be something in the slicer but I haven’t found anything. I think I picked up that these run on Marlin? So, I’m guessing test prints from slicers for Klipper based machines won’t work?

I use Orcaslicer, they have a good selection of calibration tests.

Thank you very much for that lead, I’m now using Orca Slicer. It looks like I’ll probably get better prints using it, my first completed print wasn’t good enough.
