Greg, Many thanks for that!! Now I have to ask "how in the world did that get in there?" I was using "recommended" settings and it looks like this happened with "experimental" settings. I sure don't recall setting anything under experimental other than using Tree support a couple of times.
Great to know and keep an eye out for that red circle.
Thanks again,
Len

I have been trying to get rid of my stringing issues and have played with all the recommended settings in Cura with little or no improvement. Watching the print (retraction towers) I notice the nozzle temp increased about one third the way through the print - right where the stringing began!
I went through the gcode and found two places where Cura sets nozzle temp way higher than set in the Material settings in Cura. I do not see any other place in the setting that would change the temp. Editing the gcode to make all the M104 commands read the desired temp resulted in a VERY GOOD print.Attached gcode file generated with Cura 4.7.1 using Recommended settings. Note the temp changes (M104) about 1/3 and 2/3 the way through. Starts at 205 (desired) and then goes to 245 followed by 240.
Why/where does Cura change the nozzle temp midway through the print? Is there a way to change this? retractions_2.gcodeEasy to see why I am getting stringing when nozzle temp jumps to 245 with PLA.
Tried the same retraction tower model with PursaSlicer and it also turned out pretty good.

Greg, I have no recollection of opening anybody else's files but may well have. Typically I just import (open) an STL file and slice that. I was messing around with tree supports but don't think that would cause this. Oh well, I will just watch for the red circle from now on.
All this after spending $200 and three days adding direct drive extruders to get rid of stringing. when all along it was a temperature issue. Lesson learned.
Thanks again for the help!
