This is very common on UMO and is caused by backlash which basically means the nozzle isn't moving all the way to where the stepper told it to go.
Paradoxically it is most often caused by belts too tight or too loose. If the long belts are too tight the resistance can be very high to moving the head. If the long or short belts are too loose then the head isn't moving all the way to position either.
Usually it's the short belts are too loose - loosen the 4 screws holding the motors, push down hard on the stepper and re-tighten. It's possible you need to lengthen the wood slots in the wall of the UMO but not likely.
The long belts don't need to be very tight but if you pluck them they should emit a pitch discernible by the human ear (e.g. like the lowest note on piano). As opposed to slower than 10 times per second (not audible).
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.
