cura 4.6.1 e retraction

[mario69 0]

Hello everyone, I have a fairly serious problem, in the machine setting, on the starting script of the print eg:
G21; metric values
G90; absolute positioning
M82; set extruder to absolute mode
G28
G1 X0 Y0
G92 E0; zero the extruded length
G1 F200 E20; extrude 3mm of feed stock
G1 E-2
G92 E0; zero the extruded length again
G4 P6000
The retraction is not -2mm but becomes -20mm why?

what do you mean by "The retraction is not -2mm but becomes -20mm"?

I mean that if I set a retraction of the filament of -2mm then the SW does not do it but it portrays me a lot more than 2mm I also arrive at -20mm

Why should deleting G92 E0 solve the problem?

G1 F200 E20
G1 E-2

because the e-axis moves (slowly) from E=20 to E=-2 (22mm backwards)

Those are absolute coordinates like set with M82 a few lines above.

 

Here is a quite comprehensive gcode overview: https://reprap.org/wiki/G-code

perché l'asse e si sposta (lentamente) da E = 20 a E = -2 (22mm all'indietro)

Quelle sono coordinate assolute come quelle impostate con M82 poche righe sopra.

 

Ecco una panoramica del gcode abbastanza completa: https://reprap.org/wiki/G-code

 

everything works, it was my mistake, sorry for the
  time that I made you waste

It's okay.  You just helped the next person who googles about this same problem.
