cube comes out 3x taller
-
Hi!
I own ender3 pro with default extruder and almost direct extruder (6cm Bowden).
When I print 20mm cube it comes out 3x taller (z axis). With no underextrusion present
I'm using default ender3 config from configurator

I changed the M92 Z400 to M92 Z221 and it seems allright but I would appreciate helping me understand the situation

@rudenick Just got this through the RRF Config tool, mine Ender3 is very different!
This line might help in your ;Drives section - its missing from your config
M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolationYour M92 should be this
M92 X80.00 Y80.00 Z400.00 E96.50HTH

Paul.
