Horizontal Ridges in ALL of My Parts

Thanks Waldo, I'll be looking forward to it. It seems to me that you work for Robo; is that the case? If not, I just wanted to mention that they contacted me back and told me they would provide a procedure to replace the z-axis lead screw in their online documentation. Told me a few days.

Granted, I am a mechanical engineer, so I am pretty sure I figured out the best method. But, $1500 is a lot for a graduate student, so I want to make sure the procedure I use is the recommended method. The last thing I want to do is cause more harm to the printer.

 

Well, I installed a new lead screw and z-axis motor and it seemed to completely fix the problem. And after Robo finally sent me some instructions, the replacement wasn't hard and only took about 45 minutes. One thing to note is that without those instructions, I probably would have harmed the printer more. I had no idea the entire gantry was a sub-assembly of the printer. I would not have thought it would come out so easily. Robo should post instructions online that show how to disassemble the entire printer.
