Bug: Offset (layer shift) between first and second layer when printing PLA + PVA

· Bug: Offset (layer shift) between first and second layer when printing PLA + PVA
90% of the time this is a loose pulley. First figure out if it slipped in X or Y. Then tighten all 6 pulleys (SIX - not four). on that axis. The most likely problem pulley is the one on the stepper. You should be able to get it with a long handled hex driver (it's okay to push the print head around to get access to the set screw).
Tighten the hell out of those pulleys. If you are using an L shaped allen wrench with the short arm for torque it should hurt your fingers a lot after. A lot. Tighten it so much you are scared. The steel shaft should be twisting slightly.
If you don't believe me you can mark the shaft and pulley with a sharpie such that after a layer shift you can see if you are right or I am right. Sometimes the problem is high friction or overheating stepper driver (is it above 20C in the room with the printer?) but overheating stepper driver problems usually occur after an hour of printing - not just at the start. Push the head around with your fingers to feel the friction. If one axis seems worse then oil it. Oil them anyway. Just a tiny bit of oil. Too much oil is bad. One drop on each of the 6 steel rods in the gantry. Any light oil is fine. Don't use WD40.

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.
