Quality Issue in Flexible TPU

Tue May 15, 2018 11:13 am

We have 3 printers (Robo 3d Plus with flexion extruders). we use the same gcode files for all three printers. 2 print parts perfectly. the last one has recently started having an issue with intermittent layers printing poorly. See pictures:

These layers fail when flexed. I went through the help guide. I did not see a similar issue there. So I'm trying to figure out how to resolve it.

It looks like your having an issue with layer adhesion. What temperature / speed are you using? Also, is this an old spool and how high is your humidity?
