Thank you for the input. I am planning to run the machine from either sd card or octopi/cnc image. I have been using the octopi for my printer for a bit. I bought the full graphic LCD from Ryan and just used it to run the crown test with a sharpie. had to adjust the stepper connectors to orient, but got it on my first switch. It looks good except a low spot in my mounted board where the pen didn’t draw. I am gonna be replacing with some MDF and surfacing it. All in all I am very happy thus far. If I do have a laptop hooked to the mini rambo will it power the board and the steppers to where they keep moving?
