Installed Duet WiFi firmware version 2.0. After much trial and error, I have got everything working except printing. The problem one that has been reporter before; i.e., extruder to fast but extrusion amount OK (100 mm equals 100 mm extruded). Using Ideamaker which uses M82, so changed Config.g M83 to M82. Extrusion seemed faster the when config.g M83. Also changed both config.g and code file to M83. Again seemed even faster. Copy of config.g file:

When you calibrate your e steps, are you measuring 100mm of filament before the extruder? Or are you measuring 100mm after it's left the nozzle?
It seems to have straighten itself out. I hate it when it does that for no known reason, but I glad it did it. Use it all day with no problems. Keeping fingers cross.
Before. Calculating the length of 0.4 mm of extrusion from 1.75 mm diameter and 100 mm in length ((1.75/2)^2/(.4/2)^2x100) or roughly 1914 mm or about 2 yds, but measuring would be. I just assumed if no leaks 100 mm displacement before the extruder would be 100 mm after and 100 mm at the nozzle.
Somehow it straighten it self out(I hate mysteries).
Again thank you and I am starting to enjoy the Duet WiFi.

Here's an easier way to calibrate the e steps.
