E axis endstop

agusano

Hello,

is it possible to home the E axis with a microswitch endstop? This is part of my config.

; Axis and motor configuration
M569 P0 S1									;Drive 0  (Eaxis)										
M569 P1 S1									;Drive 1
M569 P2 S0									;Drive 2 
M569 P3 S1									;Drive 3  (Eaxis)
M569 P4 S0									;Drive 4  (Eaxis)
M569 P5 S1									;Drive 5  (Eaxis)		
M569 P6 S0 									;Drive 6 			
M569 P7 S1									;Drive 7 
M569 P8 S1									;Drive 8 
M569 P9 S1									;Drive 9 


M584 X6 Y1 Z2 E3:4:0:5 U7 V8 W9 						;Custom Drive Mapping

;ENDSTOPS
M574 Z1 S1 P"zstop"								;Set active endstops low
M574 E1 S1 P"e0stop"
M574 X1 S3
M574 Y1 S3
M574 U1 S3
M574 V1 S3
M574 W1 S3

;SENSORLESS HOMING
M915 X Y U V W S3 F0 R1								;Configure motor stall detection

I want to add an endstop to de 0 and 5 drivers but both of them are tools and i'm having lots of problems.

Thank you

@agusano i don't believe endstops cal be added to extruders. why do you want to add an endstop?

@agusano You probably can, but you will need to change the extruder to a regular axis (not an extruder axis), home it, then set it back to an extruder axis. This could all be done in a macro.

@droftarts that's my new thing for today!

@agusano the only type of endstop supported for extruders is a stall detect endstop. This allows you to feed filament quickly through a Bowden extruder (typically using reduced motor current) until the filament reaches the hot end. As others have said, if you require some other sort of extruder homing, you can temporarily change it to be an axis.
