its my first printer too, not user friendly at all especially trying to use octopi it has a totally different calibration set up

No its a piece of trash and worthless buy a different printer. i will also be posting YouTube videos about how terrible this product is.

id recommend looking into a different brand printer as this one is complete and utter garbage. if you can try and sell the machine to recoup some of the costs. this machine is not worth the time and headaches trust me.

i personally used whatever cables i had laying around they were from an old computer power supply and they seem to be working fine i think its 18AWG

Having the same issue as you! and i cannot print via wireless only via SD card

There is no polarity!
