I assume it was one of the earliest models. The board was cracked along with the frame. I am now printing a frame from thingiverse to try to put these motors and the new board on because it is falling apart. I think the previous person got it from someone else too because it looks like these aren’t the original motors. I tried out the motors on a ramps 1.4 setup and they run smooth there, but seem to be running full step with the eggbot board. By the time I figure this out, I probably could have just bought the new kit. I should have the new frame printed in a couple hours and see what happens then.
