I think I solved this with the help of another post and github https://github.com/Ultimaker/Cura/blob/92691f68b6e969b07519a3dd91cff98796a765e4/resources/definitions/anet3d_a8.def.json M104 S0 M140 S0 G92 E0 ; Zero the extruder position G1 E-10 F2000 ; Retract 10mm instead of 80mm / Feed rate 2000 G28 X0 Y0 M84

I had just asked about this I think shortly before yours in regard to the Anet A8 profile. I went out to GitHub to look at the history on this: https://github.com/Ultimaker/Cura/blob/92691f68b6e969b07519a3dd91cff98796a765e4/resources/definitions/anet3d_a8.def.json Long and short of it there is a better setting: M104 S0 M140 S0 G92 E0 G1 E-10 F2000 G28 X0 Y0 M84 So - G92 E0 sets the extruder position to 0, then G1 E-10 F2000 runs an extrusion of -10mm and sets the feed rate to 2000. I'm going to give this a wing and see what happens - I was NOT happy with the 80mm retract - pulled the filament out of the extruder throat and globbed it under the hobbed gear. Had to take the thing apart to clear it.

I'm running into a slight issue with Cura 4.5's Anet A8 profile (thank you VERY much for including it) So on print end - the following gcode is executed: M104 S0 M140 S0 G92 E80 G1 E-80 F2000 G28 X0 Y0 M84 Cura 4.5 is a MARKED improvement over the previous 4.x releases. Application is very stable and starts reliably now. Upon finishing a print yesterday, I heard an interesting noise (not bad just unexpected) of the extruder retracting on completion. Today I went to run a print and kicked it off. I look over after the print completed and noticed nothing had printed out at all. I figured my filament got stuck (not remembering hearing the retract). I tried pulling out the filament manually only to have it get stuck. I let everything cool down and unbolted the cooling fan on the extruder body. Sure enough, there was a nice glob at the end of the filament below the hobbed gear. I think the retraction setting is a bit excessive. Any suggestions to tune this? Thanks in advance.
