I was getting some weird under extrusion and noticed that the gear on the extruder was a bit worn.

I decided to replace it with a dual-drive extruder, but that makes the E-step way off. I tried to run 100 mm through without any PTFE tube and only got 67 mm.

I am trying to figure out where I need to change the number.

I have the 4.2.7 motherboard, and I also put on the Creality touch screen.

It doesn't seem to have any place to enter those settings that I can find.
