18. Is UART mode supported?
Currently the robin nano 1.2 does not support UART. But UART drives can be used in
standalone mode.
19. How do I tune e-steps for my extruder stock or after market?
Not recommended for beginners.
If you tuner is either under or over extruding you may need to tune the e steps on the
extruder.
You have to be able connect to the printer with octoprint, simplfy3d, or Pronterface.
These are the ones I know and use many more will work.
Required materials. A ruler or caliper capable of measuring 120 mm. A piece of tape (I
actually tear off the sticky part of a sticky note works great for this) or marker capable of
marking on filament.
Issue command G503 Locate the M92 E##. Should be 381.5 on the coreception if you
have never changed it.
Ensure you have filament loaded and heat the extruder to your common print
temperature.
From the top of the extruder measure 120 MM and mark with tape/sticky note/marker.
Send: G1 E100 F100 This extrudes 100 mm of filament.
Once the move has completed measure from the extruder to the mark made. Let’s use
24mm as an example.
