@@ -57,7 +57,7 @@ Based on my own experiences, the following variables besides the retraction sett
 - The [feeder gear pressure](hardware/printhead.md#extruder-feeder): if it's too low, the gear can't grab the filament reliably and therefore can't retract reliably.  
 - The state of the feeder gear: if the teeth of the feeder gear which grabs the filament is kinda clogged due to debris of the filament, then it might slip as well.   
 - The quality and the state of the [nozzle](hardware/printhead.md#nozzle): low-quality nozzles as well as worn out and/or slightly clogged nozzles can increase stringing. Also the diameter of the nozzle has an impact as it determines how much filament gets extruded.   
-- The quality and the state of the PTFE tube inside of the heatbreak (Neo) or the bowden tube overall (Go).  
+- The quality and the state of the PTFE tube inside of the heatbreak.  
   As an example: stringing got way better after I replaced the stock PTFE tube with a Capricorn one, it seems that the lower friction of the Capricorn tube affected the retraction capability. Also a slightly clogged and/or deformed tip of the PTFE tube affected this a lot.  
 - [Retraction settings](calibration.md#retraction-settings), so the retraction *distance* and the retraction *speed*.  
   Even though one would usually assume that higher values should/would be better to avoid or at least deal with stringing, it's not always the case. So instead of e.g. going higher than 1mm retraction distance at the direct drive of the Neo (which would provoke clogging), go much lower and see how it goes.
