S3D is not maintaining the set extruder temp. I have set the extruder to 210 and have "wait for temp controller to stabilize" checked but at about 190 it starts to print and stays around 193 and does not show it is heating.
Is that the S3D or a printer problem? Sounds to me more like a printer problem, but I could be wrong. Have you tried another slicer on the printer recently?
