No judgement. There are a lot of details to try to learn and keep straight as you get going. Hang in there.
Makerverse hasn’t been around very long and it is only required to be used with the M2, though it recently has been upgraded to support the older systems. I have not used it more than basice movements and a cut or two on the older system just to verify it does work. There are a few who have tested it. Makerverse will work with the older kits if they have the newer firmware version ([holey-51.28.hex] (https://github.com/WebControlCNC/Firmware/releases/download/2020-05-23-1229/holey-51.28.hex)) . There are instructions on how to upload it in the wiki category of this site. The older kits will work with makerverse, webcontrol or groundcontrol, but the firmware above will only work with makerverse or webcontrol. You will need 1.26 for groundcontrol.
