I keep having feed rate issues. The knurled bolt keeps eating away at the material. I cant even print anything with out it happening. I have tried cleaning the bolt, two different materials from two different manufacturers, helping feed it, different temperatures. What am I doing wrong?
thank you for the help.

Hi Rob,
- If the tension screw is too tight, the filament will eat away at the material. Check out the following videos from Jeorgen....
- If the diameter of the filament is greater than the inner diamter of the bowden tube, you will get a jam at the cold end. I had
this problem with the stock UM filament (silver one) that i received with the kit. Also, if the bolt eats away at the filament, it can deform it, thus causing a
jam at the cold end
- Are you printing at high enough temperature? The temperature reading that I get is off by 25-30 degrees (which tested with a multimeter). So when I
was printing at 205 degrees (it was really about 180 degress) which was causing very little extrusion and filament stripping at the cold end. Eventually when I was printing at real temp of 220-225 then things started to flow better..
- Is the hot end of your bowden jammed? If your fialment diamter is the right size..and at a high enough temp( 230 degrees) can you easily
push the filament manually? If not, then your hot end of the bowden might be jammed..
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.
