http://www.boogieland.org/ReadBlog/Da-Vinci-10-Stepper-Motor-Driver-Replacement.aspx Recently, after about 5 months of using my Da Vinci 1.0, I started to run into some problems printing. The carriage seems to skip about 5mm or so in the X-Axis from time to time during printing. Sometimes this happens within the first few layers of print, which was not too bad. Sometimes it happens hours into the print. When this happens, a loud rattling sound comes out of the stepper motor. For stock firmware printers, you might see error code 0030. Perhaps I will continue this story in another post...
