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!).
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
