Ghost printing - printing in thin air - barely extruding

Kolbi

@supset I have nearly the same setup with exception of regular mosquito / not magnum and single Z. Im not sure what is causing your issue but check out my configs / writeup here and compare: https://github.com/rkolbi/RRF-machine-config-files/tree/master/Prusa MK3s
Also for Z offset, check here: https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe

Actually, re-reading your post - your machine is a bit different. What sort of leveling are you performing? Manual?

Hi,

If you can extrude from the Duet Web Interface it ought to happen when printing.

What speed did you use for the extrusion calibration test?

@supset That's good news, kinda like looking for your car keys for a minute or two and then realizing that they're in your hand.
