Help with extruder feed calibration - please! Hi, I've just fitted herringbone gears to the extruder motor (thanks iamburny) and wanted to check the feed calibration with the old felt mark, then extrude 100mm and check actual length. But for the life of me, I can't get that blasted thing to manually extrude. Am using the web interface, but have also tried it on Pronterface. No doubt I'm missing some vital step. I did it ok when the printer was first commissioned for goodness sake! So can someone put me out of my misery by figuring out what's missing?

This Doc will come in helpful once I start doing that so I know what I'm doing.

I'm still putting my O2 together (Yes I'm taking my time) and wanted to know if there is a PDF or something that has a list of all these different commands and what they are used for?

[reprap.org] lists all the commands used for all printers (not all are supported by the Duet firmware but it should be sufficient for most purposes).

Make sure you have a tool selected (e.g. send T0), and enable cold extrusion with M302 P1.
