Z axis motor off-line and looking for troubleshooting tips
In the photo of the board on the bottom of the UM, there are these 5 "stepper driver" boards that can be removed without any soldering. They are socketed. The top right one is the Z driver (notice it is closest to the connector to the Z motor).
A quick check is to swap the cables for Y and Z. Use pronterface to move the motors 1mm at a time. If the problem is with the stepper motor or the cable the problem will stay with the same stepper (it won't move).
If the problem moves to the other stepper than it's something on this circuit board so next you swap the stepper drivers aka pololu's. These are manufactured and sold both by Ultimaker or through the rep rap community. If it's not the pololu (that's the most likely thing after cabling) then it's probably the arduino (even easier and cheaper to locate and purchase!).
In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
