Continuing the discussion from Best 3D printer or kit under $400:
I just finished assembling a Max Micron aluminum frame Prusa i3 from The Online 3D Printer Store. It appears to be a solid little unit, and the hardware is good. It has a Mk3 heated bed ,Mk8 extruder and autoleveling. All up it was only $340. But I do have an issue. The home position for the XY axis are off. When I go through the menu on the LCD screen, there is nothing to set for the axis home positions. They sent me the firmware and some seemingly unrelated files as well. It just confuses things because I have no way of knowing what applies and what doesn’t. It has Marlin firmware. When I hit auto home the X axis moves all the way left, ignores the stop switch and binds the motor until I stop it. Also the X axis runs the bed all the way forward, making the auto level sensor miss the bed completely. If I can get past this hurdle, I can at least start to print. My son was a member out there and got me interested in 3D printing. I was just hoping someone there would share some of their wisdom with an old man. I might be wrong, but I can’t help but think the firmware needs to be reflashed. Any thoughts?
